Reflect shape A in the y axis

Answer:

W = 72

Step by step explanation:

White = W

Red = R

W + R = 90

Write an equation

W = 5R - 6

Substitute

5R - 6 = 90

Add 6 to both sides of the equation

5R = 90

Simplify

90 ÷ 5 = 18

R = 18

90 - 18 = W

W = 72

Final answer:

By setting up an algebraic equation, we determine that there are 74 white marbles in the bag when the total number of marbles is 90 and the white marbles count is 5 times the number of red marbles minus 6.

Explanation:

Calculating the Number of Marbles

To figure out how many white marbles are in the bag, we can set up a simple algebraic equation. Let's define the number of red marbles as x. According to the problem, the number of white marbles is 5 times the number of red marbles minus 6. We can represent this as 5x - 6. Since we know the total number of marbles is 90, we can write the equation as:

x + (5x - 6) = 90.

Combining like terms results in:

6x - 6 = 90.

Adding 6 to both sides gives us:

6x = 96.

Dividing both sides by 6, we get:

x = 16.

So, there are 16 red marbles. Now, to find the number of white marbles, we plug this back into the equation for white marbles:

5(16) - 6 = 80 - 6 = 74.

There are thus 74 white marbles in the bag.

Answer:

3.5 Gallons Per Minute or 3.5m

Step-by-step explanation:

Since there is 10.5 Gallons in 3 minutes, do

10.5/3 = 3.5

(please mark brainliest if this helps!)

Final answer:

The flow rate from the faucet is 3.5 gallons per minute. To determine the amount of water that comes out in any number of minutes, we multiply the flow rate by the number of minutes desired.

Explanation:

Given that 10.5 gallons of water are dispensed in three minutes, we can calculate the rate of flow, which will allow us to determine how many gallons of water would come out of the faucet in any other number of minutes.

We start by finding the flow rate per minute by simply dividing the volume of water dispensed by the number of minutes it took. So, the flow rate is 10.5 gallons / 3 minutes = 3.5 gallons per minute. Now, to find out how many gallons flow in any number of minutes, we multiply the flow rate (3.5 gallons per minute) by the number of minutes.

For example, if we want to know how much water comes out in 5 minutes, we calculate it as follows: Flow rate x Time = 3.5 gallons/minute x 5 minutes = 17.5 gallons. Therefore, 17.5 gallons of water would come out of the faucet in 5 minutes.

-18x-17=-53 /add 17 to both sides

-18x-17+17=-53+17

-18x=-36

x=(-36)/(-18)

Answer:  y = -5x - 22

Step-by-step explanation:

Use the Point-Slope formula: y - y₁ = m(x - x₁)

y - (-2) = -5(x - (-4))

y + 2  = -5(x + 4)

y + 2 = -5x - 20

y       = -5x - 22

Answer:

$13.299 million

Step-by-step explanation:

We need the model from Part A to answer Part B to three decimal places,

The point marked by the blue arrow is clearly an outlier. I ignored it in "eyeballing" the best-fit line.

My line has four points above and five points below the line,

You probably had to use a statistical calculator to get the equation for the line of best fit.

Assume it was

y = 38.9016 - 0.7951x

You would use that equation to predict y when x = 32.2.

y = 38.9016 - 0.7951 × 32.2 = 39.1588 - 25.6022 = 13.299

If a movie brought in $32.2 million on opening night in Tallahassee, it should bring in $13.299 million in Gainesville.

The  expected revenue be for Gainesville is $13.299 million.

here we assume that

y = 38.9016 - 0.7951x

Here that equation to predict y

when x = 32.2.

So,

y = 38.9016 - 0.7951 × 32.2

= 39.1588 - 25.6022

= 13.299

hence, The  expected revenue be for Gainesville is $13.299 million.

1) The measure needed is the C. Base area,  2) the scenario represents the equation D. 10.5= (1/3)B (4.5)

and 3) the tent will cover C. 7 square feet of the back porch.

Use the appropriate formulas to solve it step-by-step.

The formula for the volume of a cone is:

[tex]V = \frac{1}{3} \pi r^2 h[/tex]

We need to find the base area of the cone (which is a circle) to determine the area covered by the tent on the back porch. The base area (A) of the cone is:

[tex]A = \pi r^2[/tex]

To calculate this, we must first determine the radius (r) of the cone. Let's rearrange the volume formula to solve for the radius (r):

[tex]10.5 = \frac{1}{3} \pi r^2 4.5[/tex]

Simplifying this equation, we get:

[tex]10.5 = \frac{1}{3} \pi r^2 4.5[/tex]

Multiply both sides by 3 to get rid of the fraction:

[tex]31.5 = \pi r^2 4.5[/tex]

Divide both sides by 4.5:

[tex]\frac{31.5}{4.5} = \pi r^2[/tex]

[tex]7 = \pi r^2[/tex]

Divide both sides by π:

[tex]r^2 = \frac{7}{\pi}[/tex]

Taking the square root of both sides, we find the radius (r):

[tex]r = \sqrt{\frac{7}{\pi}}[/tex]

Now we can calculate the base area (A) of the cone:

[tex]A = \pi r^2[/tex]

Substitute r^2 back into the equation:

[tex]A = \pi \left( \frac{7}{\pi} \right) = 7 \text{ square feet}[/tex]

The area of a rectangle is represented by the multiplication of its length and width. For a rectangle with dimensions 'x + 5' and 'x + 4', the area is given by the standard form polynomial ' [tex]x^2 + 9x + 20[/tex]'.

The area of a rectangle is calculated by multiplying the length by the width of the rectangle. Here, the length and width of the rectangle are given by the expressions 'x + 5' and 'x + 4'. Therefore, to find the area, you multiply those two expressions together:

(x + 5) * (x + 4)

When you multiply these two expressions, you get:
[tex]x\times x + 4\times x + 5\times x + 5\times 4 = x^2 + 9x + 20[/tex]

This is the polynomial in standard form that represents the area of the rectangle,

Answer: theta ≈ 30°

Step-by-step explanation:

It said on the "show me" box at the bottom of the screen :)

The required angle of the projectile motion having range 20 m and initial velocity 15 m is 30.29°

Range of the projectile motion:

The formula for finding projectile motion is given by

Range R = [tex]\frac{v^2sin2\theta}{g}[/tex]

where v is the initial velocity and g is acceleration and [tex]\theta[/tex] is the projectile angle of the object

If we have given range and initial velocity with acceleration then by substituting above range formula we can find angle of the projectile

Here we have given that

R = 20 m

v = 15 m/s

g = 9.8 m/s^2

Therefore

[tex]20=\frac{15^2sin2\theta}{9.8}[/tex]

[tex]sin2\theta=\frac{20(9.8)}{225}[/tex]

Step-by-step explanation:

8y+1=6y+9 -Because y is equal the equations are as well.

2y+1=9- Take 6y to the other side by -6y

2y=8-Take one over by -1

y=4-Divide 8 by 2 to get y=4

Answer:

The value of y is 4

If the some of the counters in each box are the same, then A = B

If A is 8y + 1 and B is 6y + 9

Since A = B, we can say

8y + 1 = 6y + 9

Answer:

6.3 yards high

Step-by-step explanation:

The three given points are (0,0), (1,6.86), and (2,3). Use these values in f(x) = ax2 + bx + c.

For (0,0), 0 = 0 + 0 + c.

So, c = 0.

For (1,6.86), 6.86 = a + b + c. Since c = 0:

a + b = 6.86(equation 1)

For (2,3), 3 = 4a + 2b + c. Since c = 0:

4a + 2b = 3(equation 2)

Multiply equation 1 by 2, and subtract the result from equation 2:

2a + 2b  = 13.72

4a + 2b - (2a + 2b)  = 3 - 13.72

2a  = -10.72

a  = - 5.36

Plug this value into equation 1:

-5.36 + b  = 6.86

b  = 12.22

So the function is f(x) = -5.36x2 + 12.22x.

When the ball hits the ground, the height is 0, or f(x) = 0:

Use the function to determine the height of the ball, f(x), after x = 1.5 seconds.

f(x) = -5.36x2 + 12.22x

= -5.36(1.5)2 + 12.22(1.5)

= 6.27

0 = -5.36x2 + 12.22x

0 ≈ x − 2.27(Divide both sides by -5.36x.)

x ≈ 2.27 ≈ 2.3

So, the ball will be about 6.3 yards high after 1.5 seconds.
