1 mi=5280

2 mi=5280*2=10560

y = 64

Step-by-step explanation:

$\bold{METHOD\ 1:}\n\n\sqrt[3]{y}=4\qquad\text{cube of both sides}\n\n(\sqrt[3]{y})^3=4^3\n\ny=64\n\n\bold{METHOD\ 2:}\n\n\text{Use the de}\text{finition of cube root}:\n\n\sqrt[3]{a}=b\iff b^3=a\n\n\sqrt[3]{y}=4\iff 4^3=y\to y=64$

An automated car wash can wash 30 cars in 5 hours. How long would it take to wash 120 cars? A. 15 h B. 20 h C. 25 h D. 30 h

Answers

An automated car wash can wash 120 carsin 20 hours.

What is expression?

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that an automated car wash can wash 30 cars in 5 hours.

Now, an automated car wash can wash 30 cars in 5 hours.

Then, 1 car can be washed in (5/30) hours.

So, 120 cars will take (5/30 x 120) hours

(5/30 x 120)

5 x 4

20 hours

Therefore, an automated car wash can wash 120 carsin 20 hours.

At the playground, 60% of the bike rack was filled. Thisis 30 bikes. How many total slots are there for bicycles?

Answers

The most simplest way to explain this is by breaking down the 60%.

Think about it.

If 60% space = 30 bikes

then 30% space = 15 bikes

then 10% space must be 5 bikes.

So we now know for sure 60% space = 30 bikes.
And 10% space = 5 bikes.

Then we know remaining 40% space = 20 bikes.

So total space = 100% space, for 50 bikes.

Five people shared 4 whole pizzas, how much pizza did each person get?

Answers

To do this you have to divide 4 by 5. This will give you 0.8. Each person got 0.8 or 4/5 of a pizza.

If x < 5, then which of the following must be true?-x < -5
-x > -5
-x < 5
-x > 5

Answers

If x > 5, than it stands to reason that -x < 5. Say x is 17. 17 > 5, that is true, but when you add a negative in front of 17, it becomes -17 > 5, which is not true, but -17 < 5 is. The third answer choice is correct.

Answer:

-x<5
