Answer: The correct answer is 12.

Step-by-step explanation: If 20 is decreased by 40% the first thing that we need to do is calculate how much is 40% of 20.

20 x .4 = 8

Now, subtract 8 from 20:

The answer:

For the first one is definitely 0.12 
The second one I was having trouble with, but I know it is not .25 or .75. Looking at the leftover answers I would say .36 because I already used .12. Also .52 and .25 are the givens.

It takes 40 minutes for 8 people to paint 4 walls. How many minutes does it take 19people to paint 7 walls?
Slav-nsk [51]
Hey hey!


56 would be the answer.

WAIT, don’t leave just yet! You have to show at least some work! You CANT learn if you don’t know what you’re doing.

Here’s how I got the answer:

7:4 walls = 10:8 people =M:40 minutes
M = (7/4) / (10/8) x 40
M = 56 minutes.

If that helped let me know by hitting the thanks button or reply with any help you need.

Have a FABULOUS DAYYY!

A stack of round crackers are in the shape of an oblique cylinder. The diameter of each cracker is 6 centimeters and the height
tekilochka [14]

Answer: 294cm

Step-by-step explanation:

The volume of a oblique cylinder is given by:

Volume= πr^2h

where

π = 3.14

r = radius

h = height

Radius= diameter/2 = 6/2 = 3

We have all the values, so we put it in the formulae so we can get the answer.

Volume= πr^2h

= 3.14 × 3 × 3 × (0.4 × 26)

= 294cm
