The solution to the system of equations is given below.

What is function?

A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

Given is the system of equations as shown in the image.

{ 1 } -

x - 2y = - 7

2x + 5y = 8

We can write -

x = 2y - 7

Now -

2(2y - 7) + 5y = 8

4y - 14 + 5y = 8

9y = 22

{y} = 22/9

x = 44/9 - 7

x = 44/9 - 63/9

{x} = - 19/9

{ 2 } -

5x - 3y = 16

3x + 6y = 18

We can write -

5x - 3y = 16

x + 2y = 9

So -

x = 9 - 2y

5(9 - 2y) - 3y = 16

45 - 10y - 3y = 16

45 - 13y = 16

45 - 16 = 13y

13y = 29

y = 29/13

x = 9 - 58/13

x = 117/13 - 58/13

x = 59/13

Similarly, we can solve the other two system of equations.

Therefore, the solution to the system of equations is given above.

jack has 375in of sand to pour into a rectangular prism the base of the prism is 5 by 7 and the hight is 9 will the sand fit explain why or why not

Answers

Answer:

Yes, it will fit.

Step-by-step explanation:

To determine whether 375 cubic inches of sand will fit into the given rectangular prism, we need to calculate the volume of the prism and compare it to the amount of sand.

The formula for the volume of a rectangular prism is:

Volume = Base x Height x Width

In this case, the base of the prism is 5 by 7 inches, so the area of the base is:

Area of Base = 5 inches x 7 inches = 35 square inches

The height of the prism is 9 inches. Therefore, the volume of the prism is:

Volume = Base x Height = 35 square inches x 9 inches = 315 cubic inches

So, the volume of the prism is 315 cubic inches, which is less than the amount of sand Jack has (375 cubic inches). Therefore, all of the sand will fit inside the rectangular prism with room to spare.

In summary, the sand will fit inside the rectangular prism because the volume of the prism is greater than the amount of sand Jack has.

If 3 men can load a lorry of goods in 2 h, how long will it take (a) 6 men. (b) 5 men, and (e) 2 men, to load the lory of goods if they work at the same rate?​

Step-by-step explanation:

A) this one is easy....twice the manpower would take 1/2 the time = 1 hr

B) this requires a bit of calculation    find man-hrs required per lorry

    (3 men x 2 hr )/1 lorry = 6 man hours per lorry

              then:         5 men * x hr = 6 man hours

                    x =  6/5 hr    ( 1 hr 12 min)

C)  similar to B       2 men * x hr = 6 man hrs

                                         x = 6/2 hrs = 3 hrs

Answer:

see below

Step-by-step explanation:

more men = more hands = more help = less hrs cos faster

so your ans must be..

more men = less hrs

less men = more hrs

if...

3 men = 2hrs

1 man = 2hrs x 3 = 6hrs

6 men = 6hrs ÷ 6 = 1 hr

5 men = 6hrs ÷ 5 = 6/5hr = 1 1/5hrs

2 men = 6hrs ÷ 2 = 3hrs

A retailer buys merchandise from a supplier with an invoice amount of $12,400. The terms of the sale are 6/20, n/30. What is the net amount due (in $) on the order if the bill is paid by the 20th day?

Answers

If the retailer pays the invoice within 20 days and takes the discount, the net amount due is $11,656.

The sale's "6/20, n/30" clause allows the retailer to choose between paying the invoice in full within 30 days or taking advantage of a 6% discount if they do it within 20 days. If the bill is paid by the 20th day, we can determine the net amount owed as follows:

Then, we multiply the invoice amount by the discount rate to determine the amount of the discount:

Discount: $744 ($12.400 x 0.06)

The amount owed if the discount is taken is then determined by deducting the discount from the invoice amount:

Discounted amount due: $12,400 - $744 = $11,656

The net amount owed is therefore $11,656 assuming the store pays the invoice within 20 days and applies the reduction.

You create a masterpiece in your art studio and it is selected for an art exhibition. Your painting is 70 inches by 100 inches, and you choose framing that costs $4.95 per yard. Find the cost of framing.

Answers

The cost of framing for the masterpiece is $46.73.

How to calculate this

To calculate the cost, we need to first determine the perimeter of the artwork.

Given the dimensions of the artwork, the perimeter is 100 + 100 + 70 + 70 = 340 inches.

The cost of framing is $4.95 per yard, so we need to convert the perimeter to yards.

To do this, we divide the perimeter by 36 inches since 1 yard equals 36 inches.

Thus, 340 inches divided by 36 inches equals 9.44 yards.

Therefore, the cost of framing the artwork will be 9.44 yards multiplied by $4.95 per yard, which equals $46.73.

b) On average, about 240 people visit a local food pantry every day in search of groceries. On an extremely cold day, visitors to the food pantry can be 175% of the average amount. About how many visitors might go to the food pantry on an extremely cold day?

Answers

About 420 visitors might go to the food pantry on an extremely cold day

What is the percentage?

Percentage refers to a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%". For example, if 30 out of 100 students in a class are girls, the percentage of girls in the class is 30%. Percentages are commonly used in many fields, such as finance, statistics, and science, to express proportions, rates, and changes over time.

The problem states that on average, about 240 people visit the food pantry every day in search of groceries. To find out how many visitors might go to the food pantry on an extremely cold day, we need to use the given percentage increase.

The phrase "175% of the average amount" means that we need to find 175% of 240, which is the same as multiplying 240 by 1.75 (since 175% is the same as 1.75 as a decimal). Using the multiplication, we get:

175% of 240 = (175/100) * 240 = 420

So, on an extremely cold day, the number of visitors to the food pantry might be around 420.

Therefore, about 420 visitors might go to the food pantry on an extremely cold day.

Maria and Connor are doing yard work for a neighbor. They make a total of $595.54. Since Connor works more hours than Maria, Connor gets 69% of the money. About how much (in whole
dollars) does Connor make?
Connor makes about

Answers

Answer: Since Connor gets 69% of the money, Maria gets the remaining 31%:

100% - 69% = 31%

Let's first find out how much money Maria makes:

Maria's share = 31% of $595.54

Maria's share = 0.31 x $595.54

Maria's share = $184.61

Now, to find out how much Connor makes, we can subtract Maria's share from the total:

Connor's share = Total - Maria's share

Connor's share = $595.54 - $184.61

Connor's share = $410.93

Therefore, Connor makes about $410.93 (rounded to the nearest dollar).

What percentage of votes did the last-place candidate receive?

Answers

The percentage of votes received by the last or fourth candidate in the example election is about 6.4%

What is a percentage?

A percentage is a representation of a fraction of an b expressed using a denominator of 100.

A percentage is a representation of a part of whole as a fraction of 100

Therefore, the percentage of votes that a last place candidate in an election receives is the number of  votes that the last candidate receives  represented as a fraction of the total number of votes with the denominator of the fraction being 100.

An example of an election result is an election result in which the  votes received by the four leading candidates can be presented as follows;

Party A = 8,794,726

Party B = 6,984,520

Party C = 6,101,533

Part D = 1,496,687

The percentage of votes received by the Party D is therefore;

% received by party D = ((1,496,687)/(8,794,726 + 6,984,520 + 6,101,533 + 1,496,687)) × 100  ≈ 6.4%

-6 + 2 = -4

Therefore, the image of L, L', will have coordinates (-1, -4).

Looking at the given options:

A. L'(-3, 6) - This point is not on the reflected line y=-2, so it cannot be the reflection of L.

B. OL'(-1,6) - This point is above the reflected line y=-2, so it cannot be the reflection of L.

C. OL'(-1, 2) - This point is on the reflected line y=-2, but its y-coordinate is not consistent with the reflection of L. The correct y-coordinate is -4.

Here's a playground for a school of 360 children in Springfield.


1. The fence around the playground costs 90 dollars per 50-foot roll. Laying the grass across the area costs 400 dollars per 500 square feet. How much did the fencing and grass for this playground cost to build?


2. How many kids per square yard can Springfield's playground hold?


3. There's a new playground going up in nearby Wintermeadow. Wintermeadow has a budget about 3 times greater than Springfield's. Recommend a playground shape and size that would fit Wintermeadow's budget and hold at least 3 times as many kids as Springfield's playground at the same density of kids per square yard. How many kids can your playground hold?

Answers

1. The fencing and grass for this playground cost $16,360.

2. Springfield's playground can hold approximately 800 kids at a density of 25 square feet per child.

3. We can recommend a rectangular playground measuring approximately 166 yards by 40 yards, with a total area of 6,666.67 square yards. This playground should cost $49,200 for the fencing and grass.

How did we arrive at these values?

1. To calculate the cost of the fencing and grass, we first need to know the dimensions of the playground. Let's assume that the playground is a rectangular shape measuring 100 feet by 200 feet, for a total area of 20,000 square feet.

To determine the cost of the fence, we need to know how many rolls of fencing are required. Each roll is 50 feet long, so we need four rolls to fence the perimeter of the playground (100 + 100 + 200 + 200 = 600 feet / 50 = 12 rolls, but we can't buy half a roll, so we round up to four rolls). Therefore, the cost of the fence is:

4 rolls x $90/roll = $360

To determine the cost of the grass, we need to know how many square feet of grass we need to cover the playground. Since each roll of grass covers 500 square feet, we need:

20,000 sq ft / 500 sq ft per roll = 40 rolls of grass

Therefore, the cost of the grass is:

40 rolls x $400/roll = $16,000

Adding the cost of the fence and the grass, we get the total cost:

$360 + $16,000 = $16,360

So the fencing and grass for this playground cost $16,360.

2. To calculate how many kids per square yard the playground can hold, we need to know the area of the playground in square yards. There are 9 square feet in a square yard, so the playground measures:

20,000 sq ft / 9 sq ft per sq yd = 2,222.22 sq yds

Assuming that each child requires 25 square feet of space to play, we can calculate how many kids can fit on the playground:

2,222.22 sq yds x (9 sq ft per sq yd / 25 sq ft per child) = 800 kids

Therefore, Springfield's playground can hold approximately 800 kids at a density of 25 square feet per child.

3. To recommend a playground shape and size that would fit Wintermeadow's budget and hold at least 3 times as many kids as Springfield's playground at the same density of kids per square yard, we first need to know Wintermeadow's budget.

Let's assume that Springfield's budget is $50,000, so Wintermeadow's budget is $150,000.

To determine the size of the new playground, we can start by calculating the cost of the fencing and grass for Springfield's playground per square yard:

$16,360 / 2,222.22 sq yds = $7.38 per sq yd

We can then use this cost to estimate the size of the new playground. Let's assume that the new playground will also be rectangular, and that we want it to hold at least 3 times as many kids as Springfield's playground, or 2,400 kids. Using the same density of 25 square feet per child, we need:

2,400 kids x 25 sq ft per child = 60,000 sq ft

Since there are 9 square feet in a square yard, this is:

60,000 sq ft / 9 sq ft per sq yd = 6,666.67 sq yds

Multiplying this area by the cost per square yard, we get the cost of the fencing and grass for the new playground:

6,666.67 sq yds x $7.38 per sq yd = $49,200

Therefore, we can recommend a rectangular playground measuring approximately 166 yards by 40 yards, with a total area of 6,666.67 square yards. This playground should cost $49,200 for the fencing and grass.

Matrices are widely used to describe systems of equations, transformations, and data in mathematics, physics, engineering, computer science, and many other disciplines. The individual matrix components are frequently identified by their row and column positions, and matrices have a predetermined number of rows and columns. There are numerous actions that can be carried out on matrices, including addition, subtraction, and multiplication by other matrices.

given

We can write the equations in matrix form as follows to answer the simultaneous equations 1x + 4y = 9 and 2x - 3y = 7 using the matrix method:

Then, on the left side of the equation, we can locate the inverse of the coefficient matrix:

| 1 4 |^-1 = 1/(-11) | -3 -4 |

|-2 -1 |

When we multiply both sides of the equation by the coefficient matrix's inverse, we obtain:

| x | | 1 4 |^-1 | 9 |

| x | | -3/11 -4/11 | | 9 |

| y | = | -2/11 -1/11 | x | 7 |

If we simplify, we get:

x = (-3/11)*9 + (-4/11)*7 = -1

y = (-2/11)

*9 + (-1/11)

*7 = 1

Thus, using the matrix technique, the solutions to the simultaneous equations are x = -1 and y = 1.

The equation of the line of best fit is ŷ = 0.8x + 3.3

How to determine the equation of the line of best fit

From the question, we have the following parameters that can be used in our computation:

X- 14 16 29 42 43 44 47 48

Y- 11 17 31 35 37 37 38 43

When these values are entered in a graphing calculator, we have the following summary:

Sum of X = 283Sum of Y = 249Mean X = 35.375Mean Y = 31.125Sum of squares (SSX) = 1343.875Sum of products (SP) = 1055.625

For the regression equation, we have

ŷ = bX + a

Where

b = SP/SSX = 1055.63/1343.88 = 0.78551

a = MY - bMX = 31.13 - (0.79*35.38) = 3.33764

So, we have

ŷ = 0.78551x + 3.33764

Approximate

ŷ = 0.8x + 3.3

Hence, the equation is ŷ = 0.8x + 3.3

solve for x. 4(x+56.5)=30x-112

Answers

Answer:

x = 13

Step-by-step explanation:

Let's simplify and solve for x:

4(x+56.5) = 30x - 112

First, we distribute the 4:

4x + 4(56.5) = 30x - 112

Simplifying the expression:

4x + 226 = 30x - 112

Now we move all the x terms to one side and all the constants to the other:

226 + 112 = 30x - 4x

338 = 26x

Finally, we solve for x by dividing both sides by 26:

x = 13

Therefore, the solution to the equation 4(x+56.5)=30x-112 is x = 13.

Answer:

x=9.94

Step-by-step explanation:

4x + 226 = 30x - 112
226+112 = 34x
338 = 34x
338/34=x
9.94=x

The equation of the line crossing (3, 1 / 2)(5, 5) is y = 9 / 4 x  - 25 / 4.

How to find equation of a line?

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

m = slope of the lineb = y-intercept

Hence, let's find the equation of the line crossing (3, 1 / 2)(5, 5).

m = 5 - 1 / 2 / 5 - 3

m = 9 / 2 × 1 / 2

m = 9  / 4

Hence, let's find the y-intercept using (5, 5)

y = 9 / 4 x + b

5 = 9 / 4(5) + b

5 - 45 / 4 = b

b =  20 - 45/ 4

b = - 25 / 4

Therefore, the equation of the line is y = 9 / 4 x  - 25 / 4.

Which of the lines or segments below is secant to circle

Answers

The lines or segments which are secant to a circle are:  

AK, TW, RN & UN

What is secant of the circle?

A line that crosses a circle at two different locations is referred to as a "secant of a circle" in geometry. The Latin verb "secare," which meaning "to cut," is where the English term "secant" originates.

More technically, a secant of a circle is a line that crosses it twice, whereas a tangent of a circle is a line that crosses it only once. A circle's diameter is a chord that runs through its center, whereas a chord of a circle is a line segment connecting two locations on the circle.

Given that,

Two circle which contains various tangents, normal & secants

As we know from the definition of secant it intersect the circle at two points,

Line segments AK, TW, RN & UN are intersecting the circle at two points,

so all this segments are secant of the circle.

Hence, a 93% confidence range for the actual proportional difference between the two populations equation (represented by the two samples) is between -0.086 and 0.142.

What is the equation?

A mathematical equation connects two statements with the equals sign (=), which stands for equivalence. The equivalence of two mathematical propositions is established by a mathematical assertion that is utilized in algebraic equations. For instance, the equal sign separates the numbers 3x + 5 and 14 in equation 3x + 5 = 14. Use a mathematical formula to understand the relationship between the two sentences written on opposite sides of a letter. Usually, the program's particular logo matches it. A good example is 2x - 4 = 2.

For the initial example:

Sample proportion: 0.649 (p1 = 24/37)

Standard deviation SE1 is equal to

[tex]\sqrt{(p^1*(1-p^1))} /n1=\sqrt{(0.649*(1-0.649))/37)0.087}[/tex]

Regarding the second example:

P2 = 54/87 0.621 is the sample proportion.

The standard deviation SE2 is equal to

[tex]\sqrt{(p^2*(1-p^2))} /n2=\sqrt{(0.621*(1-0.621))/87)0.72}[/tex]

The crucial value for a 93% confidence interval has to be calculated next. We may use the conventional normal distribution and large sample size to obtain the z-value that represents the center 93% of the distribution:

[tex]1.812z=invNorm(\frac{1+0.93}{2} )[/tex]

We can finally determine the confidence interval:

CI is equal to (p1-p2) z*sqrt(SE12 + SE22)

CI is calculated as (0.649 - 0.621) 1.812*sqrt(0.0872 + 0.0722)

CI = 0.028 ± 0.114

CI = (−0.086, 0.142)

The real proportional difference between the two populations (represented by the two samples) thus lies between -0.086 and 0.142, with a 93% confidence interval.

There is a slave completely at the mercy of his brutal master's whims. He often is cruellybeaten, called out in the middle of the night, and so on.2. The master is kindlier and beats the slave only for stated infractions of his rules (notfulfilling the work quota, and so on). He gives the slave some free time.3. The master has a group of slaves, and he decides how things are to be allocated among themon nice grounds, taking into account their needs, merit, and so on.4. The master allows his slaves four days on their own and requires them to work only threedays a week on his land. The rest of the time is their own.5. The master allows his slaves to go off and work in the city (or anywhere they wish) forwages. He requires only that they send back to him three-sevenths of their wages. He alsoretains the power to recall them to the plantation if some emergency threatens his land; andto raise or lower the three-sevenths amount required to be turned over to him. He furtherretains the right to restrict the slaves from participating in certain dangerous activities thatthreaten his financial return, for example, mountain climbing, cigarette smoking.6. The master allows all of his 10,000 slaves, except you, to vote, and the joint decision is madeby all of them. There is open discussion, and so forth, among them, and they have the powerto determine to what uses to put whatever percentage of your (and their) earnings theydecide to take; what activities legitimately may be forbidden to you, and so on.Let us pause in this sequence of cases to take stock. If the master contracts this transfer of power sothat he cannot withdraw it, you have a change of master. You now have 10,000 masters instead ofjust one; rather you have one 10,000-headed master. Perhaps the 10,000 even will be kindlier thanthe benevolent master in case 2. Still, they are your master. However, still more can be done. Akindly single master (as in case 2) might allow his slave(s) to speak up and try to persuade him tomake a certain decision. The 10,000-headed monster can do this also.7. Though still not having the vote, you are at liberty (and are given the right) to enter into thediscussions of the 10,000, to try to persuade them to adopt various policies and to treat youand themselves in a certain way. They then go off to vote to decide upon policies coveringthe vast range of their powers.8. In appreciation of your useful contributions to discussion, the 10,000 allow you to vote ifthey are deadlocked; they commit themselves to this procedure. After the discussion youmark your vote on a slip of paper, and they go off and vote. In the eventuality that theydivide evenly on some issue, 5,000 for and 5,000 against, they look at your ballot and countit in. This has never yet happened; they have never yet had occasion to open your ballot. (Asingle master also might commit himself to letting his slave decide any issue concerning himabout which he, the master, was absolutely indifferent.)9. They throw your vote in with theirs. If they are exactly tied your vote carries the issue.Otherwise it makes no difference to the electoral outcome.The question is: which transition from case 1 to case 9 made it no longer the tale of a slave?
