5 or lower: (1,1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (3,2), (4,1)

There are 9 valid rolls out of 36 total possible rolls = 9/36 = 1/4

Water tank a has a capacity of 550 gallons and is 66% full. Water tank b is 53% full . The ratio of the tank a to tank b is 11:1

garik1379 [7]

A/B = 11/15 OR 15 x A = 11.B OR B= 15A/11

Actual Gallons in A = 550 x 66 % = 363 gal

Total capacity of B = 15A/11 OR (15 x 550)/11 = 750 gal.

Actual Gallons in B = 750 x 53% = 397.5 gal

Total surface area of a cube is 1014cm^2. It's volume will be :

rewona [7]

Answer:

$V=2197\ cm^3$

Step-by-step explanation:

<u>Surface Area and Volume of a Cube</u>

Given a cube of side length a, the surface area is:

$A = 6a^2$

The volume is calculated as:

$V=a^3$

It's given the surface area of a cube:

$A=1014\ cm^2$

We can find the side length a by solving for a:

$\displaystyle a=\sqrt{\frac{A}{6}}$

$\displaystyle a=\sqrt{\frac{1014}{6}}$

$\displaystyle a=\sqrt{169}$

a = 13 cm

Now compute the volume:

$V=13^3$

$\boxed{V=2197\ cm^3}$

Answer: a) 2197 cm^3
