How long will jesse take to run a total of 50 miles if she run 0.13 per hour

Answers

Answer 1
Answer: Jesse runs 0.13 miles per one hour.
She wants to run a total of 50 miles.

0.13 miles .... 1 hour
50 miles ... x hours

We would like to know how long this will take (x hours). You can calculate this in the following way:
0.13 * x = 50 * 1   /0.13
x = 50/0.13
x = 384.6153846153846154 (hours)

The result is 384.6153846153846154 hours.
Answer 2
Answer: 384.61538462 hours is the answer.

Jodie bought some shirts for $6 each marge bought some shirts for $8 each the girls spent the same amount of money on shirts what is the least amount they could have spent

Answers

All this is asking you to do is find the LCM (least common multiple) of 8 and 6. So if you list them out this is what you get:
6: 6,12,18,24
8:8,16,24,32
So you can see that the multiple 24 is common between them. Now just add the two together and you have your answer: 48$

Peter figures he can build the entire tree house by himself in 20 hours. He figures that each additional friend who helps him would improve the time by 10%. He created a table using the algebraic expression n – n(0.10), where n is the previous number of hours.To the nearest tenth of an hour, how long will it take to build the tree house if 4 friends are helping?
It will take
hours.

Answers

If four friends assist, it will take 13.12 hours to construct the tree home.

What is algebraic Expression?

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

Given this, Peter figures he can build the entire tree house by himself in 20 hours. He figures that each additional friend who helps him would improve the time by 10%.

An algebraicexpression that determines the given condition is:

n – n(0.10)

=> n(1- 0.1)

=> n* 0.9

Since the above equation is for A friend and it's given there are four friends helping him.

Thus,

The final time is taken in building the tree house if 4 friends are helping:

=> n * 0.9^4

Where n is 20

=> 20 * 0.9^4

=> 13.122

Therefore, it will take 13.12 hours to build the tree house if 4 friends are helping.

A gallon of milk costs $5.12. What is the price, in dollars, of an 8 ounce glass of milk? There are 128 ounces in 1 gallon.

Answers

Answer:

$.32

Step-by-step explanation:

To find the unit price, we take the cost and divide by the units.  We will take the cost and divide by 128 ounces since that is how many ounces in a gallon.

$5.12 / 128 ounces

$.04 per ounce

I need to find the price of an 8 ounce glass of milk, so I multiply by 8 ounces

$.04 per ounce * 8 ounces = $.32

My 8 ounce glass of mile costs $.32
The answer to your question is $.32
