A quadrilateral has a total area of 36. 18 square inches. One of the sides measures 6. 7 inches. How long is the other side? inches



(do not include any words in the answer blank)

Answers

Answer 1

The length of the other side of the quadrilateral is 10.67 inches.

The other side of the quadrilateral measures 10.67 inches. This can be found by using the formula for the area of a quadrilateral, which is (1/2) x diagonal x height. We know the total area and one side length, so we can solve for the height. The height is 10.67 inches, which is the length of the other side.

To find the length of the other side of the quadrilateral, we need to use the formula for the area of a quadrilateral, which is (1/2) x diagonal x height.

We know the total area of the quadrilateral is 36.18 square inches, and we can assume that the side given (6.7 inches) is one of the diagonals. We can solve for the height, which represents the length of the other side.

Using algebra, we can rearrange the formula to solve for the height:

Area = (1/2) x diagonal x height

36.18 = (1/2) x 6.7 x height

Multiplying both sides by 2:

72.36 = 6.7 x height

Dividing both sides by 6.7:

height = 10.67 inches

Answers

The  function f(x)=500[tex]x^2[/tex] +10,000  can  be  used  to  model  the  food  vendor's  annual  revenue. The  food  vendor  would expect  to  bring  in  $ 60,000  in  annual  revenue by 10 years from now.

To find out when the mobile food vendor should expect to bring in $60,000 in annual revenue using the function f(x) = 500x^2 + 10,000, follow these steps:

1. Set the function equal to 60,000: 500[tex]x^2[/tex]+ 10,000 = 60,000
2. Subtract 60,000 from both sides of the equation: 500[tex]x^2[/tex]+ 10,000 - 60,000 = 0
3. Simplify the equation: 500[tex]x^2[/tex]- 50,000 = 0
4. Divide both sides by 500:[tex]x^2[/tex] - 100 = 0
5. Add 100 to both sides: [tex]x^2[/tex] = 100
6. Find the square root of both sides: x = ±10

Two circles, C1 and C2, intersect at point A and B. Passes through the center O of circle C2. The point P lies on circle C2 so that the line PAT is target to circle Ci and point A. Let ∠APB =.

Answers

The value of ∠APB = 180°. It is a straight line.

Given the information, we can deduce that the line passing through the center O of circle C2 and point A also passes through point B, as AB is the intersection of the two circles.

Now, consider the line segment AP. Since PAT is tangent to circle C1 at point A, we know that ∠APT = 90°. Additionally, since AB is a diameter of circle C1, we know that ∠ABP = 90°.

Using these angles, we can see that ∠APB is equal to the sum of ∠APT and ∠ABP. Therefore,

∠APB = ∠APT + ∠ABP = 90° + 90° = 180°.

So, we have shown that ∠APB is a straight line.

You buy a sheet with 10 stamps. Some are 45 cents and some are 30 cents. If it cost $4. 20 how many of each did you get

Answers

You bought 8 stamps that cost 45 cents each and 2 stamps that cost 30 cents each.

Let's assume you bought x stamps that cost 45 cents each and y stamps that cost 30 cents each.

From the given information, we can create two equations:

The total number of stamps is 10: x + y = 10.

The total cost is $4.20: 45x + 30y = 420 (since the cost is given in cents).

Now we can solve this system of equations to find the values of x and y.

We can multiply the first equation by 30 to eliminate y:

30x + 30y = 300.

Now we have a system of equations:

30x + 30y = 300,

45x + 30y = 420.

Subtracting the first equation from the second equation, we get:

45x + 30y - (30x + 30y) = 420 - 300,

15x = 120,

x = 120/15,

x = 8.

Substituting the value of x back into the first equation:

8 + y = 10,

y = 10 - 8,

y = 2.

Therefore, you bought 8 stamps that cost 45 cents each and 2 stamps that cost 30 cents each.

Complete the statements by selecting the correct answer from each-down menu. Carl's transactions for a year are given in the table. His broker charged him $5 per trade. How much does Carl pay his broker?

Answers

Carl pays his broker a total of $200 in fees for the 40 trades he made during the year.

To calculate how much Carl pays his broker, we need to first determine how many trades he made in a year. Looking at the table, we can see that Carl made a total of 40 trades - 20 buys and 20 sells. Since each trade incurs a $5 charge, we can multiply the number of trades by the cost per trade to get the total amount paid to the broker.

40 trades x $5 per trade = $200 paid to the broker in a year

It's important to note that transaction costs can have a significant impact on investment returns, especially for small accounts, so it's important to consider these costs when making investment decisions. Some brokers may offer lower transaction fees or other incentives to attract clients, so it's worth shopping around and comparing fees before choosing a broker.

Answers

The equation of the line that passes through (1, 2) and (a) having a slope of 2/3 is y = (2/3)x + 4/3, (b) Having an undefined slope is x = 1, (c) having slope m = 0 is y = 2 (d) point (2, 3) also lies on the line is y = x + 1.

a) To find the equation of a line with slope 2/3 passing through (1,2), we can use the point-slope formula:
y - y1 = m(x - x1)
Substituting in the values we know, we get:
y - 2 = (2/3)(x - 1)
Expanding and simplifying:
y = (2/3)x + 4/3
So the equation of the line is y = (2/3)x + 4/3.

b) To find the equation of a line with an undefined slope passing through (1,2), we know that this line must be vertical. The equation of a vertical line passing through (1,2) can be written as:
x = 1

So the equation of the line is x = 1.

c) To find the equation of a line with slope m=0 passing through (1,2), we know that this line must be horizontal. The equation of a horizontal line passing through (1,2) can be written as:
y = 2
So the equation of the line is y = 2.

d) To find the equation of a line passing through (1,2) and (2,3), we can use the point-slope formula again:
y - y1 = m(x - x1)
Substituting in the values we know, we get:
y - 2 = (3 - 2)/(2 - 1)(x - 1)
Simplifying:
y - 2 = 1(x - 1)
y - 2 = x - 1
y = x + 1
So the equation of the line is y = x + 1.

Answers

Let's denote the total distance traveled by the object as `d` and time as `t`.

We can use the given information to set up a system of equations:

When t = 10.0 seconds, d = 50.0 meters

50.0 = a(10.0)^2 + b(10.0) + c         (Equation 1)

When t = 20.0 seconds, d = 200.0 meters

200.0 = a(20.0)^2 + b(20.0) + c          (Equation 2)

When t = 0 seconds, d = 0 meters

0 = a(0)^2 + b(0) + c           (Equation 3)

Simplifying Equation 3, we get c = 0.

Substituting c = 0 in Equations 1 and 2, we get:

50.0 = 100a + 10b               (Equation 4)

200.0 = 400a + 20b              (Equation 5)

We can solve Equations 4 and 5 simultaneously to get the values of `a` and `b`:

From Equation 4, we get:

10b = 50 - 100a

b = 5 - 10a

Substituting this value of `b` in Equation 5, we get:

200.0 = 400a + 20(5 - 10a)

200.0 = 400a + 100 - 200a

200.0 = 200a + 100

100.0 = 200a

a = 0.5

Substituting this value of `a` in Equation 4, we get:

50.0 = 100(0.5) + 10b

50.0 = 50 + 10b

b = 0

Therefore, the quadratic function that models the total distance traveled by the object is:

[tex]d = 0.5t^2[/tex]

To find the total distance traveled by the object after 30.0 seconds, we can substitute `t = 30.0` in the above equation:

[tex]d = 0.5(30.0)^2[/tex]

d = 450.0 meters

Therefore, the object will travel a total distance of 450.0 meters after 30.0 seconds.

Find the average rate of change of g (x) = 2x² - 7x from x = 1 to x = 6.
Simplify your answer as much as possible.

Answers

The average rate of change of g(x) from x = 1 to x = 6 is 7

Finding the average rate of change of g(x)

The average rate of change of a function over an interval is given by the difference in the values of the function at the endpoints of the interval, divided by the length of the interval.

In this case, we want to find the average rate of change of g(x) = 2x² - 7x from x = 1 to x = 6.

The value of g(x) at x = 1 is:

g(1) = 2(1)² - 7(1) = -5

The value of g(x) at x = 6 is:

g(6) = 2(6)² - 7(6) = 30

So the difference in the values of g(x) is:

g(6) - g(1) = 30 - (-5) = 35

The length of the interval is:

6 - 1 = 5

Therefore, the average rate of change of g(x) from x = 1 to x = 6 is:

Rate = 35/5

Evaluate

Rate = 7

So, the rate is 7

The average rate of change is 7.

We know that,

The average rate of change = (final value - initial value)/change in the value of x.

Now,

The given function is,

g(x)=2x²-7x

The initial value of x is 1 (given)

∴ The initial value of the function g(x), at x=1,

g(1)=2(1)²-7(1)=2-7

or, g(1)= -5

Now, the final value of x is 6,

∴ Finding the final value of the function g(x) at x=6,

i.e, g(6)=2(6)²-7(6)

or,  g(6)=72-42 = 30

∴ The change in the value of function g(x), from x= to x=6,

= g(6)-g(1)

= 30-(-5)

= 35

Now, change in the value of x = 6-1=5

∴ The average rate of change = 35/5 = 7

Hence the average rate of change is 7.

Lisa has 9 rings in her jewelry box. Five are gold and 4 are silver. If she randomly selects 3 rings to wear to a party, find each probability. P(2 silver or 2 gold)

Answers

The probability of selecting 2 silver rings or 2 gold rings is 3/28.

How to find the probability of selecting 2 silver rings or 2 gold rings?

To find the probability of selecting 2 silver rings or 2 gold rings, we need to find the probability of each event separately and then add them.

Probability of selecting 2 silver rings:

There are 4 silver rings out of 9 total, so the probability of selecting a silver ring on the first draw is 4/9. After the first ring is selected, there are 3 silver rings left out of 8 total, so the probability of selecting a second silver ring is 3/8. Finally, after two silver rings have been selected, there are 2 silver rings left out of 7 total, so the probability of selecting a third silver ring is 2/7. Therefore, the probability of selecting 2 silver rings is:

(4/9) * (3/8) * (2/7) = 24/504 = 1/21

Probability of selecting 2 gold rings:

Similarly, there are 5 gold rings out of 9 total, so the probability of selecting a gold ring on the first draw is 5/9. After the first ring is selected, there are 4 gold rings left out of 8 total, so the probability of selecting a second gold ring is 4/8 = 1/2. Finally, after two gold rings have been selected, there are 3 gold rings left out of 7 total, so the probability of selecting a third gold ring is 3/7. Therefore, the probability of selecting 2 gold rings is:

(5/9) * (1/2) * (3/7) = 15/126 = 5/42

Adding the probabilities of selecting 2 silver rings or 2 gold rings, we get:

P(2 silver or 2 gold) = P(2 silver) + P(2 gold) = 1/21 + 5/42 = 3/28

Therefore, the probability of selecting 2 silver rings or 2 gold rings is 3/28.

A model airplane flew the distance of 330 feet in 15 seconds. Select ALL the unit rates that are equivalent to the speed of the model airplane.

Answers

All of the unit rates that are equivalent to the speed of the model airplane are 22 feet per second, 1320 feet per minute, and 0.25 miles per minute.

To calculate the speed of the model airplane, we need to use the formula:

Speed = Distance / Time

Given that the distance covered by the model airplane is 330 feet, and the time taken is 15 seconds, we can substitute these values in the above formula to get:

Speed = 330 feet / 15 seconds

Simplifying this, we get:

Speed = 22 feet per second

To convert this unit rate to other equivalent unit rates, we need to use conversion factors. For example, to convert feet per second to feet per minute, we can multiply the unit rate by 60 (since there are 60 seconds in a minute):

22 feet per second x 60 seconds per minute = 1320 feet per minute

Similarly, to convert feet per minute to miles per minute, we can use the conversion factor 1 mile = 5280 feet:

1320 feet per minute / 5280 feet per mile = 0.25 miles per minute

Therefore, all of the unit rates that are equivalent to the speed of the model airplane are 22 feet per second, 1320 feet per minute, and 0.25 miles per minute.

Answers

Hello!

In this question, we are asked to find which set of points are solutions to our equation: 7x + 4y = -23

In order to find which points are solutions to our equation, we will plug the values into our equation and solve. If both sides of the equation are equal, the point will be a solution.

Note: Our coordinate point is in the format of (x,y), so we will plug in the values according to its variable.

Solve:

(-1,-4):

Plug in coordinate.

7(-1) + 4(-4) = -23

Simplify.

-7 - 16 = -23

-23 = -23

Since it is equal, (-1,-4) is a solution.

(2,6):

Plug in coordinate.

7(2) + 4(6) = -23

Simplify.

14 + 24 = -23

38 = -23

Since it is not equal, making it false, (2,6) is not a solution.

(-5,3):

Plug in coordinate.

7(-5) + 4(3) = -23

Simplify.

-35 + 12 = -23

-23 = -23

Since it is equal, (-5,3) is a solution.

(6,-7):

Plug in coordinate.

7(6) + 4(-7) = -23

Simplify.

42 - 28 = -23

14 = -23

Since it is not equal, making it false, (6,-7) is not a solution.

Answer:

The solutions to the equation are: (-1,-4) and (-5,3).

7x + 4y = -23
x = -1; y = -4
7*(-1) + 4*(-4) = -23
-7 - 16 = -23
-23 = -23

x = -5; y = 3
7*(-5) + 3*4 = -23
-35 + 12 = -23
-23 = -23

If m< a=3x and m< d=4x+6 what is the value of x?

Answers

Based on the given information that angles a and d are equal, the value of x is determined to be -6.

To find the value of x in the given scenario, we can equate the measures of the angles using the given information:

m< a = 3x

m< d = 4x + 6

Since angles a and d are stated to be equal, we can set up the equation:

3x = 4x + 6

To solve for x, we subtract 3x from both sides:

0 = x + 6

Next, we subtract 6 from both sides:

-6 = x

Therefore, the value of x is -6.

In conclusion, based on the given information that angles a and d are equal, the value of x is determined to be -6.

Kira had 3/5 acres land she planted 3/7 of it with corn. How many acres did she plant with corn?

Answers

Kira planted 9/35 acres with corn.

If Kira planted corn on 3/7 of her land total of 3/5 acres, what is the area she planted with corn?

To find out how many acres planted with corn, we first need to understand that the total amount of land she had was 3/5 acres. Then, we know that she planted 3/7 of her land with corn.

To calculate the area planted with corn, we multiply the total area of her land (3/5 acres) by the fraction that represents the portion she planted with corn (3/7). This gives us:

(3/5) x (3/7) = 9/35 acres

Therefore, Kira planted 9/35 acres of her land with corn.

We can simplify the fraction by dividing both the numerator and the denominator by their greatest common factor, which is 3 in this case. This gives us:

(9/3) / (35/3) = 3/11 acres

So, Kira planted approximately 0.26 acres with corn.

Which equation has the same solution as x^2-10x-3=5?

Answers

Answer:

Step-by-step explanation:

To find the equation that has the same solution as x^2 - 10x - 3 = 5, we can start by simplifying the left side of the equation by adding 8 to both sides:

x^2 - 10x - 3 = 5

x^2 - 10x - 8 = 0

Now we need to find an equation with the same solutions as this simplified equation. We can do this by factoring the quadratic equation into two linear factors:

x^2 - 10x - 8 = 0

(x - 2)(x - 8) = 0

Therefore, the solutions to the equation x^2 - 10x - 3 = 5 are x = 2 and x = 8. We can write two equations that have these solutions:

(x - 2) = 0

(x - 8) = 0

So the two equations that have the same solution as x^2 - 10x - 3 = 5 are x - 2 = 0 and x - 8 = 0. These equations can be simplified as x = 2 and x = 8, which are the same solutions as the original quadratic equation. Therefore, the equations x - 2 = 0 and x - 8 = 0 have the same solution as x^2 - 10x - 3 = 5.

Answer:

(x - 5)^2 = 33

Step-by-step explanation:Add 3 to both sidesx^2 - 10x - 3 = 5Simplifyx^2 - 10x = 8Calculate the "magic number":b = -10 → b/2 = -5 → (b/2)^2 = 25Add the magic number to both sidesx^2 -10x + 25 = 8 + 25Factor left side(x - 5)(x - 5) = 33Rewrite left side as a perfect square(x - 5)^2 = 33

Find the linear approximation for the following function at the given point. b. Use part (a) to estimate the given function value. f(x,y)= - 4x² + 2y² ; (3, -3); estimate f(3.1,- 3.01) a. L(x,y)= b. L(3.1, – 3.01)= (Type an integer or a decimal)

Answers

The estimate for f(3.1, -3.01) using the linear approximation is approximately -54.28.

a. To find the linear approximation of f(x,y) at the point (3,-3), we need to find the gradient of the function at that point.

∇f(x,y) = [-8x, 4y]

So, at the point (3,-3), the gradient is ∇f(3,-3) = [-24, -12].

The linear approximation is given by:

L(x,y) = f(3,-3) + ∇f(3,-3)·(x-3,y+3)

Plugging in the values, we get:

L(x,y) = -4(3)^2 + 2(-3)^2 - 24(x-3) - 12(y+3)

Simplifying, we get:

L(x,y) = -12x - 4y - 36

b. To estimate f(3.1, -3.01) using the linear approximation, we plug in the values into the equation we found in part (a):

L(3.1, -3.01) = -12(3.1) - 4(-3.01) - 36

L(3.1, -3.01) ≈ -54.28

Therefore, the estimate for f(3.1, -3.01) using the linear approximation is approximately -54.28.
