2.1 liters of coffee were equally distributed to 30 cups. How many milliliters of coffee were in each cup?

Answers

Answer 1

Answer:

The amount of coffee in each cup is the average coffee in the cups.

The amount of coffee in each cup is 70mL

The given parameters are:

$\mathbf{Size = 2.1L}$

$\mathbf{Cup = 30}$

So, the amount in each cup is:

$\mathbf{Amount = (Size)/(Cup)}$

Substitute known values

$\mathbf{Amount = (2.1L)/(30)}$

$\mathbf{Amount = 0.07L}$

Convert liters to milliliters

$\mathbf{Amount = 0.07 * 1000mL}$

$\mathbf{Amount = 70mL}$

Hence, the amount of coffee in each cup is 70mL

Answer 2

Answer:

70 ml

Further explanation

Given:

2.1 liters of coffee were equally distributed to 30 cups.

Question:

How many milliliters of coffee were in each cup?

The Process:

Step-1: converting liters into milliliters

Recall $\boxed{ \ 1 \ liter = 1,000 \ milliliters \ }$

Let us change the 2.1 liters unit of coffee into milliliters.

$\boxed{ \ 2.1 \ liters * (1,000 \ mL)/(1 \ liter) = \ ? \ }$

$\boxed{ \ = 2.1 * 1,000 \ mL} \ }$

$\boxed{ \ = 21 * (1)/(10) * 1,000 \ mL} \ }$

$\boxed{ \ = 21 * 100 \ mL} \ }$

$\boxed{\boxed{ \ 2,100 \ mL \ }}$

Therefore, 2,100 mL of coffee are available for distribution.

Step-2: calculating how many milliliters of coffee were in each cup

$\boxed{ \ 30 \ cups = 2,100 \ mL \ }$

$\boxed{ \ 1 \ cups = \ ? \ mL \ }$

We have to divide the total amount of coffee by the number of cups.

$\boxed{ \ 1 \ cup * (2,100 \ mL)/(30 \ cups) * 1,000 \ mL = \ ? \ }}$

$\boxed{ \ = (2,100)/(30) \ }$

The numerator and denominator are equally divided by 10.

$\boxed{ \ = (210)/(3) \ }$

$\boxed{ \ = 210 / 3 \ }$

$\boxed{\boxed{ \ 70 \ }}$

Thus, 70 milliliters of coffee were in each cup.

A standard beach volleyball court is approximately 26 feet by 52 feet. She figures that she will need the sand to be one foot deep. She goes to the hardware store to shop for sand and sees the following signs on pallets containing bags of sand. Sand A is 60 lbs for $5 and Sand B is 150 lbs for $12. She uses her cell phone to search how many pounds of sand is required to fill 1 cubic foot and finds the answer is 100 pounds. Use brand A and compute how much it will cost Alisa to purchase enough sand to fill the court.

Volume of a rectangular prism:

V = lwh

V = (52)(26)(1)

V = 1352 cubic feet

1 cubic foot = 100 pounds

100 * 1352 = 135,200

Sand A = 60 pounds for $5

135,200 / 60 = 2253.33

2253.33 * 5 = $11,266.65

How do i round 3,176 to the nearest thousand

Answers

Here is the rule: 4 and below let it go (round down), 5 and above give it a shove (round up)
Look to the place after the thousandths in the number 3,176 (the 1)
Since it is below 5, you would round down to 3,000

Well you would look at the 176 in 3,176. Since it is less then half (500) you would round it down. So 3,176 rounded to the nearest thousand would be 3,000
