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

How to tell whether its a prime or composite number

Answers

Prime numbers have only 2 factors 1 and its number for example:
2, 3, 5, 7, 11, 13, 17, 19, 23

Like this 1*2. Or 3*1

Composite numbers have more than two factors for example :
0, 4, 6, 8, 9, 10, 12, 14 15, 16..

For example 0 has many factors
0 times 3 0times 4

Step-by-step explanation: You know that it is a prime if the only number divisible by the number is one. If there are more numbers than 1 then it is composite.

!HELP! SHOW WORK PLEASE SO I CAN UDNERSTAND!A paper drinking cup in the shape of a cone has a height of 10 centimeters and a diameter of 8 centimeters. Which of the following is the closest to the volume of the cup in cubic centimeters?
167 cm³
209 cm³
670 cm³
502 cm³

Answers

Ok.

The volume of a cone is the volume of a cylinder over 3.

The volume of a cone is:
$(1)/(3) \pi r^(2)h$

This problem gives us the diameter, which is twice of the radius. So, we'll just half it.
Radius (me) = 4 cm.

Substitute our given values into the equation.
$(1)/(3) \pi (4)^(2)h \ or \ (1)/(3) \pi (4)^(2)(10) \ or \ (1)/(3) \pi (16)(10)$

Multiply
$(1)/(3) \pi(160) \ or \ (1)/(3) (3.14)(160) \ or \ 1.047(160)$

Multiply
$167.52 \ cm^(3)$

This would make $167 \ cm^(3)$ the closest option.

The formula for the volume of a cone is π r²h/3. You are given the height and the diametre of the cone. You need the radius which is half the diametre (4). So, f you were to write this out, it would look like this:

3.14 × 4² × 10/3

your answer is going to be 167 cm³

Drew purchased 3 books each with a different price, for $24. The cost of each bookj was a multiple of 4. What could be the prices of the 3 books?

What is 1 and 1/2 minus 7/8

Answers

Convert 1 and 1/2 to eights to make it easier to subtract. 1 4/8 add 1 to 4/8
12/8 then subtract that by 7/8 straight across the numerator. That then equals 5/8

You would find a common denominator 8. 1 and1/2 would be converted into 1 and4/8. 1 and 4/8 minus 7/8 equals 5/8

What is the answer to 9x8 2/3

Answers

The answer is 78. This is because you change 8 2/3 into a improper fraction which is 26/3. Then do 26/3×9/1. You should cross cancel so cancel out 3 and change it into 1 and change 9 into 3. So now your problem is 26×3=78.
~JZ
Hope it helps.

9 x 8 2/3.

First, make 9 a fraction: 9=9/1.

Then, make 8 2/3 a improper fraction: 8 2/3=26/3.

Now, we multiply: 9/1×26/3=234/3.

Finnally, we simplify: 234/3=78.

Therefore, the answer is 78.
