You're just changing the given rate into a unit rate: follow along and do the division shown and fill in the blanks. 320 ÷16 = 20

So the unit rate is $\frac{20mi}{1gal}$

Do 320/16 and that will equal 20 and don’t pay attention to the denominators because they already put a 1 for you.

Find the distance between the two numbers on a number line. Write your answer as a mixed number.

Answer:

We conclude that the distance between the two numbers on a number line will be: 322

Step-by-step explanation:

Given the numbers

-212

-534

There can be a lot of ways to determine the distance between the two numbers on a number line like counting every number between them.

But, we can use a more efficient method in terms of determining the distance by taking the absolute value of the difference between those numbers.

Distance between the numbers:

$\left|-212-\left(-534\right)\right|$

Apply rule: -(-a) = a

$=\left|-212+534\right|$

$=\left|322\right|$

Apply absolute rule: $\left|a\right|=a,\:a\ge 0$

$=322$

Therefore, we conclude that the distance between the two numbers on a number line will be: 322

The diameter of a planet is about 1420 mi. Find the volume of the planet. Round to the nearest thousand cubic miles. Use 3.14 fo

Ainat [17]

Answer:

1,498,454,000 sq. miles

Step-by-step explanation:

Volume of a sphere = 4/3 (3.14) r^3

So since the diameter is 1420 miles, the radius would be half.

V = 4/3 x (3.14) x 710^3

V=4.18666667 x 357,911,000

V = 1,498,454,054.5 but if you want it rounded to the nearest thousand then it'd be 1,498,454,000.
