The coordinates of B would be (2, -4)

In order to find this, we need to know that the value of M's points will always be the average of A and B's points. This is because it is the midpoint. Therefore we can use the following formula.

Value of x

(A + B)/2 = M

(-8 + B)/2 = -3

-8 + B = -6

B = 2

Then we can do the same for the y values

Value of y

(A + B)/2 = M

(-2 + B)/2 = -3

-2 + B = -6

B = 4

Answer:

24 cars

Step-by-step explanation:

Given

$Red:Blue = 3:2$

$Cars = 40$

Required

Determine the number of red cars

Number of red cars is calculated using:

$Red\ Cars = \frac{Red\ Ratio}{Total\ Ratio} * Cars$

$Red\ Cars = \frac{3}{3 + 2} * 40$

$Red\ Cars = \frac{3}{5} * 40$

$Red\ Cars = \frac{3 * 40}{5}$

$Red\ Cars = \frac{120}{5}$

$Red\ Cars = 24$

Anyone know this ? I don’t understand math

MrMuchimi

Answer:

99cm^2

Step-by-step explanation:

When finding an area of a triangle, you multiply base times height and then divide by 2.

In this case,

Height:11

Base: 18

So then apply the formula:

$\frac{11*18}{2}$

Solve (using a calculator lol)

We get 99

Don't forget units!

So the final answer is 99cm^2

Charra [1.4K]

Answer:

A = 314 inches^2

Step-by-step explanation:

We know the diameter of the glass. We need to find the radius

d = 2r

20 = 2r

Divide each side by 2

20/2 = 2r/2

10 =r

To find the area of the glass

A = pi r^2

A = pi * 10^2

A = pi*100

A = 100 *(3.14)

= 314 in^2
