56*(4+15/60)

56*(240+15)/60

56*(255)/60

238 miles

Well you need to first convert 4hrs and 15 minutes to either a decimal hours or minutes, I would do minutes so 255 minutes. Then you set up a proportion of 56miles xmiles
----------- = --------------- Then solve 60x=(56*255)
60 minutes 255 minutes 60x=14280
----- ---------
60 60
x= 238
so the answer is 238miles

Answer: h(3)= -4 h(-3)=-16

Step-by-step explanation:

Plug in 3 and -3 for x and solve

Suppose you are driving 60 miles per hour. what is your rate of speed in miles per minute?

Verdich [7]

So if it is 60 miles per hour it is basically 60 miles per 60 minutes. $\frac{60}{60}$ when you simplify it, it is going to be 1/1=1 The answer is 1 mile per minute

In isosceles triangle ABC, AC=BC=20, the measure of angle A=68, and CD is the altitude to side AB. What is CD to the nearest 10t

Answer:

Step-by-step explanation:

Comment

The way the diagram looks when it is drawn is that you are going to need the sine function to solve for the side opposite which is CD.

Formula

Sin(A) = Sin(68 = opposite / hypotenuse Substitute values.

Solution

sin(68) = altitude (side opposite) / 20 multiply both sides by 20

20*sin(68) = 20* altitude / 20 substitute for sin(68)

20* 0.9272 = altitude

altitude = 18.5

Answer: 18.5 to the nearest tenth
