If 14 gallon of paint covers 13 of a wall in Luna's bedroom, how much paint does she need to cover 1 wall?

Travka [436]

Answer:

182

Step-by-step explanation:

1/13=14 gal

14 times 13 = 182 gal.

Unless you wrote it diff, then it would be 14/13 = 1.08 gal (I don't think this one is correct though)

Three yards of fabric will be cut into pieces so that each piece is 8 inches long. How many pieces can be cut? (1 yard = 36 inch

In-s [12.5K]

You have 3 yards and each piece of fabric needs to be 8inches long. Convert yards into inches. Divide it by 8.

3yds= 108 inches
108/8= 13.5

You can cut 13.5 pieces of fabric.

Have a good day :)

A hypothetical cube grows so that the length of its sides are increasing at a rate of 2 m/min. How fast is the volume of the cub

Karolina [17]

Answer:

In a min the volume increased by 296m^3

Step-by-step explanation:

Volume of cube = v^3

At 8m = V = 8*8*8 = 512

Since it's growing at 2m/min

The previous volume A min ago would have been

8m - 2m = 6m

V = 6*6*6 = 216

So in a minute, the volume had gone from 216 to 512

The speed = 512 - 216 = 296

So it's volume increased by 296 in a min.

Just for future clarification.

(2 min ago the volume would have been.

8m - (2*2)m = 4

V 2min ago = 4*4*4 = 64.

At 2mins ago the volume changed by 216 - 64 = 152.

So this is what the volume looked like Each minute

0, 8, 64, 216, 512, 1000.)

Find the population standard deviation (σ not S) for the data set: {75,80,90,95,75,85,55,80,90,95}

Marianna [84]

The steps to work out standard deviation is as follows

Step 1: Find the mean of the data

$\frac{75+80+90+95+75+85+55+80+90+95}{10}=82$

Step 2: Subtract the mean from each data value

$75-82=-7$
$80-82=-2$
$90-82=7$
$95-82=13$
$75-82=-7$
$85-82=3$
$55-82=-27$
$80-82=-2$
$90-82=8$
$95-82=13$

Step 3: Add up the answers from step 2 $\sqrt{2.9}=1.7$

$-2+(-2)+7+13+(-7)+3+(-2)+(-2)+8+13=29$

Step 4: Divide the answer is step 3 by the number of data

$\frac{29}{10}=2.9$

Step 5: Square root the answer in step 4

$\sqrt{2.9} =1.7$
