Answer:

4 (5 + 4)

Step-by-step explanation:

1. the model show 20 + 16 which = 36

2. the first example 4 (5) + 4 which equals 20 + 4 or 24.

3. the second example 4 + 5 + 4 which equals 9 + 4 or 13.

<u><em>4. the third example 4 (5 + 4) , using order of operations, equals 4 x 9 and that equals 36.</em></u>

5. the last examples 5 (4 + 4) is 5 x 8 which is 40.

That is why the third example is correct!

Answer:

4(5+4)

Step-by-step explanation:

20 + 16 = 36

Think of PEMDAS (In this scenario you have parenthesis and addition)

4(5+4) = 20 + 16

4 (9) = 36

36 = 36

While looking at the other options:

4 (5) + 4 = 24

4 + 5 + 4=13

5 (4 + 4)= 40

A half-filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the dia

Anettt [7]

Answer:

d = 13.8 feet

Step-by-step explanation:

Because we are talking about cubic feet of water, we need the formula for the VOLUME of a cylinder. That formula is

$V=\pi r^2h$

We will use 3.141592654 for pi; if the tank HALF filled with water is at 20 feet, then the height of the tank is 40 feet, so h = 40; and the volume it can hold in total is 6000 cubic feet. Filling in then gives us:

$6000=(3.141592654)(r^2)(40)$

Simplify on the right to get

$6000=125.6637061r^2$

Divide both sides by 125.6637061 to get that

$r^2=47.74648294$

Taking the square root of both sides gives you

r = 6.90988299

But the diameter is twice the radius, so multiply that r value by 2 to get that the diameter to the nearest tenth of a foot is 13.8
