The difference of seven squared and eight

Answer:

Step-by-step explanation:

From the graph attached,

Relation between the amount of money raised and number of car washed is represented by a straight line.

Let the equation of the line is,

y = mx + b

where m = slope of the line = charges for each car wash

b = y-intercept = Initial amount the team have before the car wash.

Slope of the line will define the charges of car wash for each car.

Since, slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of the line passing through (0, 100) and (10, 150) will be,

m = [tex]\frac{150-100}{10-0}[/tex]

m = 5

Therefore, charges of each car wash will be = $5

y-intercept of the line 'b' = 100

Equation of the line will be,

y = 5x + 100

If team wants to earn $300,

300 = 5x + 100

5x = 200

x = 40

Therefore, 40 cars will be needed to wash by the swim team to earn $300.

1) The amount of money the swim team charged for each car that it washed is; $5 per car

2) The amount of money that the swim team had in its account before the car wash is; $100

3) If the team wants to earn $300, then number of cars they need to wash is; 40 cars

We know that formula for slope between two points is;

m = (y₂ - y₁)/(x₂ - x₁)

Let us take 2 coordinates from the given graph which are;

(10, 150) and (30, 250)

Thus;

m = (250 - 150)/(30 - 10)

m = 100/20

m = 5

Now, the equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

From our graph, the y-intercept is 100. Thus, equation of the line of the graph is;

y = 5x + 100

A) From our equation y = 5x + 100, we can say that number of cars are x and as such amount charged per car is $5 per car.

B) The amount of money the swim team had before washing cars is when the value of x is 0. Thus;

y = 5(0) + 100

y = $100

C) The team wants to earn $300 and so we will plug 300 for y into y = 5x + 100 to get;

300 = 5x + 100

5x = 300 - 100

5x = 200

x = 200/5

x = 40 cars.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Population mean (μ) = 1076

Sample mean (m) = 1436

Number of samples (n) = 40

Population standard deviation (sd) = 276

α=0.10

Null: μ = 1076

Alternative : μ > 1076

This is a right tailed test;

Reject null;

If z > z0.10

Z0.10 = 1.28 ( right tailed)

Test statistic (z) :

(m - μ) / (σ / √n)

(1436 - 1076) / (276 / √40)

360 / 43.639431

= 8.249

Since

8.249 > 1.28

We reject the null.

B) using the p value calculator from Zscore and alpha level

Zscore = 8.249 ; α=0.10, one tailed

P value < 0.00001

Which shoes that result is significant at 0.10

Answer: A,b,e

A:Each successive output is the previous output divided by 3.

B:As the domain values increase, the range values decrease.

E:The range of the function is all real numbers greater than 0.

Step-by-step explanation:

h-1=5h+3h-8

Combine like terms

h-1 = 8h-8

Subtract h from each side

h-1-h = 8h-8-h

-1 = 7h-8

Add 8 to each ide

-1+8 = 7h

7 =7h

Divide by 7

Answer:

[tex]x=42.5^o[/tex]

Step-by-step explanation:

Notice that this is an isosceles triangle, so the angles opposite to the sides of equal length (40 units) must be equal. That means that angleD = angleE

Then using the rule for addition of interior angles of a triangle equal to 180, we can write:

angleD + angleE + angleF = 180 degrees

x + x + 95 = 180

2 x = 180-95

2 x = 85

x = 85/ 2

x = 42.5 degrees

Answer:

42.5

Step-by-step explanation:

Side EF = 40

Side DF = 40

that means it is a equilateral triangle so:

Angle ∠E = Angle ∠D (which is x)

(180-95) / 2

= 42.5

Answer:

x = 16

Step-by-step explanation:

We know that line a and b are parallel so they each have the same slope therefore, (7x + 2) = (8x - 14).

First we have so isolate a number value and x.

So we subtract 7x from 8x, which looks like:

2 = (x - 14)

Then we have to get that -14 to the other side, so we add and that looks like:

16 = x

Therefore, we have our answer, x = 16.

Answer:

there is no whole number

Step-by-step explanation:

Answer:

Step-by-step explanation:

Translated point (-1,-3). The point moved to the right 2 (horizontal) and up 2 (vertical).

The coordinate of translated point would be (-1,-3) and its movement is vertically upside and horizontally right side of the coordinate system.​

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Vertical shifting of a graph is done by adding any arbitrary constant to the function in shifting.

For example, If shift up by 1 unit,  add 1 to the function

If shift down by 4 units, subtract 4 from the function

The original coordinate is (-3, -5).

Translate the point (-3, -5) using the rule, x→+2, and y→+2,

The coordinate of translated point would be (-3+2, -5+2) = (-1, -3).

Here the movement is vertically upside and horizontally right side of the coordinate system.​

Answer:

y=7x - 2

Step-by-step explanation:

Slope- intercept form is - y=mx+b

In this equation, you would start off by isolating y.

So, you would move 7x to the right side like so-

7x -y =2

-7x        -7x

Now you have

-y= -7x +2

Next step is to divide all number by -1 since you have -1y

-y=-7x+2

/-1    /-1   /-1

Now you have

y = 7x -2

Answer: 40%

Here is how I solved it:

Step 1: Convert into percentages.

2,000 = 100%.

Step 2: Find 50% of 2,000.

2,000 - 1,000 = 1,000.

Step 3: Subtract 200 (20%)

1,000 - 200 = 800.

Step 4: Convert 800 of 2,000 into a fraction.

[tex]\frac{800}{2000}[/tex] = 800/2000

Step 5: Reduce the fraction.

800/2000 reduced = 8/20.

Step 6: Convert 8/20 into a percent.

800 = 40% of 2,000

Answer = 40%.

Answer:

3400, If it's a decimal version then, 3.39

Step-by-step explanation:

3,389

The 8 is after the 3/the hundreds place. So you round the 8 because the 8 is greater then 5 and then you get 3,400. Decimal version: 3.34, the hundreds place in the decimal is the second digit to the right of the period. 3.389 = 3.34 9 is greater then 5. Your welcome :)

29.93 ℃

Step-by-step explanation:

Temperature (K) = ℃ + 273

302.93 K = ℃ + 273

302.93 - 273 = 29.93℃

At 29.78 °C gallium can melt our hand.

To convert temperatures in degrees Celsius to Fahrenheit, multiply by 9/5 and then add 32.From here we can also convert degree Fahrenheit to degree celsius. The S.I unit of temperature is Kelvin.

According to the given question

Gallium is a metal that can melt in your hand at 302.93 k. what is the temperature in celsius.

The conversion formula from kelvin to celsius  is

°C = K - 273.15

Given it can melt our hand at 302.93 k

∴ °C = (302.93 - 273.15)k

  °C = 29.78.

Step-by-step explanation:

Answer:

m∠3 = 38.9°

Step-by-step explanation:

If all three angles of a triangle adds up to 180° (Triangle Sum Theorem), it is a right angle (meaning that one of the angle measures is 90°), and m∠1 = 51.1°, then:

m∠1 + m∠2 + m∠3 = 180° (Triangle Sum Theorem)

51.1° + 90° + m∠3 = 180° (Substitution Property of Equality)

141.1° + m∠3 = 180° (Addition Property of Equality)

m∠3 = 38.9° (Subtraction Property of Equality)

Answer:

39

Step-by-step explanation:

assuming the angles are 57 & 84

141 + 57 > 180

123 + 57 = 180 (no room for an 8)

96 + 57 = 153

180 - 153 = 27 (an 8 doesn't work for this answer)

57 + 39 = 96

180 - 96 = 84 ( we have a winner!)
