Answer:

y = 10

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{y}{20}$ = $\frac{1}{2}$ ( cross- multiply )

2y = 20 ( divide both sides by 2 )

y = 10

Convert the map scale to a unit rate. How many inches represent one mile? Show your work. Interpret the meaning of the unit rate

Veronika [31]

Verbal model: mile/inch=mile/inch

Proportion: 7/8÷3/10=x/1

Solve= 7/8*10/3=x/1

70/24=x/1

70=24x

x=35/12

The unit rate must be $\frac{35}{12} miles/ inch$
