7/8 of a liter of milk is poured into glasses that can each hold 1/16 of a liter. How many glasses can be filled?

Otrada [13]

Divide total milk by amount per glass.

When dividing by a fraction flip the fraction over and multiply:

7/8 x 16/1 = (7 x16) / ( 8 x1) = 112/8 = 14

Answer: 14 glasses

The label on the car's antifreeze container claims to protect the car between −30°C and 130°C. To convert Celsius temperature to

Sveta_85 [38]

we know that

$C = \frac{5}{9}(F-32)\\ \\F=\frac{9}{5}C+32$

Step $1$

Find the inequality

we know that

$C = \frac{5}{9}(F-32)$ --------> equation $1$

and

$-30\° < C < 130\°$

substitute the equation $1$ in the inequality

$-30\° < \frac{5}{9}(F-32) < 130\°$

Step $2$

Convert $-30\°C$ to F

substitute in the formula

$F=\frac{9}{5}*(-30)+32\\ \\F= -22\°$

Step $3$

Convert $130\°C$ to F

substitute in the formula

$F=\frac{9}{5}*(130)+32\\ \\F= 266\°$

therefore

$-22\° < F < 266\°$

the answer is the option

B. −30 < 5 over 9 (F − 32) < 130; −22 < F < 266

Find f(2) for the function below f(x) = (1/8) times 5^x

Mrrafil [7]

Step-by-step explanation:

$f(x) = \frac{1}{8} \times {5}^{x} \\ \\ \therefore \: f(2) = \frac{1}{8} \times {5}^{2} \\ \\ \therefore \: f(2) = \frac{1}{8} \times 25 \\ \\ \huge \red{ \boxed{ \therefore \: f(2) = \frac{25}{8} }}$
