Answer: B. 19.9

Step-by-step explanation: Set up an equation where sin and the degree angle is in the numerator, and the side length is in the denominator.

Sin65/8 = Sinx/3

Plug Sin65 into your calculator and you will get 0.9063. Divide this number by 8.

0.9063/8 = 0.1133

Your equation is now 0.1133 = sinx/3

Multiply by 3 on each side.

0.3399 = sinx

Put sin on the left side. It will look like:

Sin^-1(0.3399) = x

Press enter on your calculator. You will get

X = 19.9.

Answer: 4230.14

Step-by-step explanation:

The amount that the balance is multiplied by each month is

$\frac{2448}{2040}=1.2$ .

So, after t months, the balance is $1700(1.2)^{t-1}$ .

Substituting in t=6, we get the balance is

$1700(1.2)^{6-1}=\boxed{4230.14}$ , to the nearest hundredth.

Answer:

$12.5(x + 20) = 460 \\ x + 20 = 460 \div 12.5 \\ x + 20 = 36.8 \\ x = 36.8 - 20 \\ x = 16.8$

Hence, 16.8 miles is your answer
