Answer:

D. 21.

Step-by-step explanation:

The general form of the equation of a circle is:

(x - a)^2 + (y - b)^2 = r^2 where r is the radius.

Comparing:

(x + 5)^2 + (y + 7)^2 = 21^2

So r^2 = 21^2

making r = √21^2

= 21.

2.1 liters of coffee were equally distributed to 30 cups how many millimeters of coffee were in each cup

sattari [20]

Answer: 70 ml of coffee in each cup

Step-by-step explanation:

1 liter = 1000 ml

Amount of coffee given = 2.1 liters

$\Rightarrow$ 2.1 liters = 2.1 * 1000 = 2100 ml

Total number of cups = 30

$\therefore$ Amount of coffee in each cup = $\frac{Total\ amount \ of \ coffee}{number\ of \ cups}$ = $\frac{2100}{30}$ =70

∵ Amount of coffee in each cup = 70 milliliters
