Answer:

(-12, -10)

Step-by-step explanation:

Midpoint M is the average of endpoints A and B:

M = (A +B)/2

2M = A + B . . . . . . multiply by 2; next, subtract A

B = 2M - A . . . . . . the missing endpoint can be found this way

B = 2(-8, 0) -(-4, 10) = (2(-8)+4, 2(0)-10) = (-12, -10)

If you have an old fish tank in the form of a circular cylinder and it is 2 feet in diameter and 6 feet tall, how many cubic fee

yuradex [85]

Answer:

The old fish tank hold 18.84 cubic feet of water.

Step-by-step explanation:

Given:

An old fish tank in the form of a circular cylinder and it is 2 feet in diameter and 6 feet tall.

Now, to find the cubic feet of water the fish tank hold.

Dimensions of old fish tank are:

Diameter is 2 feet so. we find the radius first.

Radius ( $r$ ) = $\frac{Diameter}{2}=\frac{2}{2}=1\ feet.$

Height ( $h$ ) = $6\ feet.$

Now, to get the cubic feet off water the tank hold we put formula:

(Taking the value of π as 3.14.)

$Volume=\pi r^2h\\\\Volume=3.14\times 1^2\times 6\\\\Volume=3.14\times 1\times 6\\\\Volume=18.84\ cubic feet.$

Therefore, the old fish tank hold 18.84 cubic feet of water.

An office building casts a 90 foot shadow. At the same time of day, a 5 foot woman standing near the building casts an 8 foot sh

Elenna [48]

Make a ratio:

Make sure shadow is in same location on both fractions (either numerator or denominator) 

x/90=5/8

Cross multiply:

8x=90x5
8x=450

x=56.25 feet 

Therefore, the approximate height of the building to the nearest foot would be 56.25 feet.

That makes sense, too, because the woman's shadow is taller than she is, but is less than double her height. The building shadow is taller than the building, but it's less than double the height of the building.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
