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 <u>unit rate,</u> 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.

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

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

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

<u>Divide both sides by 25:</u>

\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}}
