The answer is 399

PEMDAS

First is parenthesis, 20 - 8 = 12

Then exponents, 4^3 = 64

Since the 12 is still in parenthesis, you multiply it by the 64 and you get 768.

Moving onto the D in PEMDAS, you have to divide the 768 by 2 and you get 384.

And finally, addition. 384 + 6 = 390 and 390 + 9 = 399.

Anyone can find this?
Mademuasel [1]

Answer:

a=34 °

b=76°

c=70°

d=70°

Step-by-step explanation:

The angles 76° , 34°, and c make up a triangle. A triangle has a sum of 180°.

180° = 76° + 34° +c

c=70°

The parallel lines create 2 congruent triangles so we can use the same angles from the first triangle for the second one.

A cylindrical tank has a radius of 15 ft. and a height of 45 ft. How many cubic feet of water can the tank hold?
vladimir1956 [14]
The formula to solve for this would be pi(r^2)xheight. Essentially what this formula does is it takes the are of the base (pi x r^2) and multiplies it by the height of the cylinder to find how many times the base can stack on itself until it reaches the top. This formula of base are times height works for all prisms with two bases. Here are the steps to solve:

1) plug in the values
- pi(15^2) x 45

2) solve for the base area of one of the circles
- pi(15^2)=225pi

3) multiply the base area by the height
- 225pi x 45 = 10,125pi

4) final answer: the tank can hold 10,125pi cubic feet of water

Which expression is equivalent to 6+4.5(32f-14f)
vichka [17]

Answer:

6 + 4.5(32f - 14f) = 6 + 81f

Step-by-step explanation:

Let us apply the distributive property to find an equivalent expression for:

6  + 4.5(32f - 14f)

For all real numbers a, b, and c, the distributive property says that:

a(b + c) = ab + ac

We apply this property to get:

6 + 4.5(32f - 14f) = 6 + 4.5 \times 32f  + 4.5 \times  - 14f

6 + 4.5(32f - 14f) = 6 + 144f   - 63f

We simplify the RHS to get:

6 + 4.5(32f - 14f) = 6 + 81f
