You traveled 120 miles

You are traveling at 50mph

So divide 120 by 50

$120$ ÷ $50= 2\frac{20}{50}$ ⇒ $2 \frac{2}{5}$

Answer: You traveled $2 \frac{2}{5}$ hours or $2.4$ hours

Suppose Johnny invests $41,745 into an account, which has been earning interest for many years and he now has a total of $39,974

It would not be reasonable for Johnny to have a negative amount in the investment. This is because you cannot earn negative dollars. And he is not spending money in this case. Therefore, it is unreasonable for him to have a negative number for this situation.

Use right triangle ABC, with right angle C, as shown to answer the question.

The ratios are: sin B = 4/5 , cos B = 3/5 and tan B = 4/3

Step-by-step explanation:

We can see in the diagram that the values of all sides are given. In case of trigonometric ratios, the side in front of angle under consideration is perpendicular and the side adjacent to angle is base.

In the given case, we have to find trigonometric ratios for angle B; So,

Base = a = 3

Perpendicular = b = 4

Hypotenuse = c = 5

Hence,

The ratios will be:

$sin\ B = \frac{perpendicular}{hypotenuse} = \frac{b}{c} =\frac{4}{5}\\cos\ B = \frac{base}{hypotenuse} = \frac{a}{c} =\frac{3}{5}\\tan\ B = \frac{perpendicular}{base} = \frac{b}{a} = \frac{4}{3}$
