Answer:
4 hours
Step-by-step explanation:
Since we know he travels at a rate of 1:7.5 all we have to do is divide 7.5 by 30. Do you use proportions? You can set this up as a proportion and the find answer easily.
1
Now we cross product.
7.5 multipled by x =7.5x
1x30=30
so now we have
7.5x=30
Now we have to divide 7.5 on both sides which gives us
x=4
Area=3.14(r)^2
radius is half of diameter
3.14(9.5)^2=283.385
rounded is 283.39
The statements that are true are:
A. m<AGB = 19°
D. <BGD is a right angle
<h3>What is a Right Angle?</h3>
A right angle is an angle that measures 90 degrees.
Given the diagram, where:
m<AGC = 38°,
m<CGD = 71°,
m<FGC = 147°
We have the following measures:
1/2(m<AGC) = m<AGB
1/2(38) = 19°
m<CGD + m<AGC = m<BGD
Substitute
71 + 19 = m<BGD
90 = m<BGD
m<BGD = 90° [this is a right angle].
Therefore, the statements that are true are:
A. m<AGB = 19°
D. <BGD is a right angle

Mikes repair shop $100 service charge plus $65 per hour Amys auto repair $40 service charge plus $80 per hour write an equation for each repair shop to represent the total cost of a car repair as a function of the number of hours worked let C = total cost to you let h = number of hours worked. Suppose you need to get the dent in your car repaired you see the ads above in the newspaper your father who knows a bit about cars said it would take no more than 3 hours for the repair person to fix your car how do you determine where you should take your car to get it repaired
-Mike Cost:: M(3) = 100 +65*3 = $295
-Amy Cost:: A(3) = 40 + 80*3 = $280
------------------------------------------------------------
-Mike charges 100 dollars service charge plus 65 dollars per hour.
-Amy charges 40 dollars service charge plus 80 dollars per hour.
-The cost to repair from mike is 100 + 65 * x.
-The cost to repair from amy is 40 + 80 * x.
------------------------------------------------------------
Let x = 3 and you get:
The cost to repair from mike is 100 + 65 * 3 = 295 dollars.
The cost to repaid from amy is 40 + 80 * 3 = 280 dollars.
As long as the time to repair is 3 hours or less, the cost to repair will be cheaper from Amy.
