When you write an equation, it tells you, that you know what the math problem is and your steps of solving. For example if the math problem was that:

Trina invited 9 girls and 10 boys to her birthday. 2 girls didn't come and 1 boy didn't come. What is the total amount of people that came to Trina's birthday party.

Equation: 9+10-2-1=?

Answer would be: 9+10=19   
19-4=15.

So only 15 people came to Trina's birthday party!

:) Hope I helped!

What is the missing dimention with a cilinder with base as d and the height as 14 and it has a volume of 7433 in 3
Korolek [52]

Answer:

26in

Step-by-step explanation:

Volume of a cylinder = πr²h

Given

height h = 14in

Volume = 7433in³

Required

base d = 2r

r is the  radius

get the radius r

7433 = 3.14 * 14r²

7433 = 43.96r²

r² = 7433/43.96

r² = 169.08

r = 13.00

Since the base d = 2r

d = 2(13)

d = 26in

Hence the base of the cylinder is 26in

Three friends all live on the same street that runs west to east. Ben lives 8 blocks from ann. Carol lives 2 blocks from ben. If
Romashka-Z-Leto [24]

Answer:

i. 10 units (Carol's house is 10 units on the right from Ann's house)

ii. -10 units (Carol's house is 10 units on the left to Ann's house)

Step-by-step explanation:

A number line is a system that can be used to express the location of directed number on a straight line. It has an origin which is taken to be zero (0).

In the given question, Ann's house is located at 0 of the number line. Let 1 block be represented by 1 unit on the number line.

Thus, Ben lives 8 blocks from Ann implies that Ben's house is at 8 units from Ann's house.

Given that Carol's house is 2 blocks from Ben implies that Carol's house is 2 units from Ben.

So that,

The possible locations of Carol's house depends on its position with respect to Ann's house.

i. Carol's house = 8 + 2

                          = 10 units

This implies that Carol's house is 10 units on the right from Ann's house.

ii. Carol's house = - 8 - 2

                           = -10 units

This implies that Carol's house is 10 units on the left to Ann's house.
