8a - 4b = 20<br>5a - 8b = 62<br><br>What are the values of a and b?

erastovalidia [21]

Answer:

a=2 , b= (-1)

Step-by-step explanation:

8a-4b=20/×(-2)

5a-8b=62

-16a+8b= -40

5a-8b=62

now -8+8=0 right? so the only parameter that we have is a.

-16a+5a= -40+62

11a = 22/(÷11)

a=2

in order to find b, we will replace a with its value in one of the original equations (it doesn't matter which one you will choose).For instance, I chose the first one.

8×2-4b=20

-4b=20-16

-4b=4/÷(-4)

b= -1

Water flows at a rate of 8000 cubic inches per minute into a cylindrical tank. The tank has a diameter of 128 inches and a heigh

beks73 [17]

Answer:

The height of the water = 6.2 in. to the nearest tenth

Step-by-step explanation:

∵ The rate of flows of water into the tank = 8000 in.³/min.

∴ The volume of the water in the tank after 10 min. = 8000 × 10 = 80000 in.³

∵ The water take the shape of the tank

∴ The height of the water = volume of water ÷ Area of the base of the tank

∵ The tank is cylinder with diameter 128 in. and height 72 in.

∴ The area of the base of the tank = π(128/2)²

∴ The height of the water = $\frac{80000}{\pi(64)^{2}}=6.2169899$

∴ The height of the water = 6.2 in. to the nearest tenth
