<h3>Further explanation</h3>

<u>Given:</u>

2.1 liters of coffee were equally distributed to 30 cups.

<u>Question:</u>

How many milliliters of coffee were in each cup?

<u>The Process:</u>

<u>Step-1:</u> 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 \times \frac{1,000 \ mL}{1 \ liter} = \ ? \ }

\boxed{ \ = 2.1 \times 1,000 \ mL} \ }

\boxed{ \ = 21 \times \frac{1}{10} \times 1,000 \ mL} \ }

\boxed{ \ = 21 \times 100 \ mL} \ }

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

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

<u>Step-2:</u> 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 \times \frac{2,100 \ mL}{30 \ cups} \times 1,000 \ mL = \ ? \ }}

\boxed{ \ = \frac{2,100}{30} \ }

The numerator and denominator are equally divided by 10.

\boxed{ \ = \frac{210}{3} \ }

\boxed{ \ = 210 \div 3 \ }

\boxed{\boxed{ \ 70 \ }}

Thus, 70 milliliters of coffee were in each cup.

Answer:

g = 55

f = 55

h = 55

Step-by-step explanation:

g = 180 - 25 = 55

this is because angle on a straight line is equal to 180 degrees

f = 55

alternate angles are equal. f alternates g

h = 55

opposite angels are equal

Ivanna will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $40 and costs an a
natka813 [3]
First, let's make these two into equations.
The first plan has an initial fee of $40 and costs an additional $0.16 per mile driven.
Our equation would then be
C = 40 + 0.16m
where C is the total cost, and m is the number of miles driven.
The second plan has an initial fee of $51 and costs an additional $0.11 per mile driven.
So, the equation is
C = 51 + 0.11m
where C is the total cost, and m is the number of miles driven.
Now, your question seems to be asking for one mileage for both, equalling one cost. I would go through all the steps I've taken to try and find this for you, but it would probably take hours to type out and read. In short, I'm not entirely sure that an answer like that is possible in this situation, simply because of the large difference in the initial fee of the two plans, along with the sparse common multiples between the two mileage costs.

The system shown at the right has no solution, as the grahs never intersect.
On the other hand, the line and the parab. at the left do intersect, and the points of intersection are (-3,0) and (6,6).
