Answer:

a = 7.5

Step-by-step explanation:

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

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{a}{15}$ = $\frac{1}{2}$ ( cross- multiply )

2a = 15 ( divide both sides by 2 )

a = 7.5

A cyclist travels a distance of 837 1/2 feet in 25 seconds. The cyclist travels at a constant rate. What is the unit rate, in fe

wel

Answer:

$\boxed{33.5 \ \text{feet/second}}$

Step-by-step explanation:

To find the unit rate, we need to find out how much distance does the cyclist travel in 1 second. For that, we need to use the unitary method. A unitary method is a method that determines the unit rate of an object.

Note: Since the cyclist travels at a constant rate, unitary method can be used.

$\rightarrow 837 \dfrac{1}{2} \ \text{feet in 25 seconds}$

$\rightarrow 837.5 \ \text{feet} = 25 \ \text{seconds}$

Divide both sides by 25:

$\rightarrow \dfrac{837.5}{25} \ \text{feet} = \dfrac{25}{25} \ \text{seconds}$

$\rightarrow 33.5 \ \text{feet} = 1 \ \text{seconds}$

$\rightarrow \boxed{33.5 \ \text{feet/second}}$
