13). z = ( 9/13)(C)
Solve for C:
Step 1: flip Equation:
9/13 c = z
Step 2: Divide both sides by 9/13
9/13 c/9/13 = z/9/13
C = 13z/9
Answer: Letter Choice, (D), C = 13z/9
12.). Let " h" be the number of hikes:
Expense of First Club:
C * h = 20 + 5h
Expense of Second CluB:
C * h = 7h
20 + 5h < 7h
20 < 2h
h > 10 hikes
Answer: The First Club is Less Expensive, If it is more than Ten Hikes.
14.). Co-Efficient of Friction Formula:
ma = F - mw
+ mw + mw (cancel out +mw)
Mw + ma = F - ma
-ma -ma (Cancel out -ma)
Divide: Both sides by w:
Mw/w = F - ma/w
Therefore, Answer: Letter Choice, (D), M = F - ma/w
Hope that helps!!!! Have a wonderful day!!!! : )
No, it's not a function because 2*6=12, but 6*4=24. In order for it to be an actual proportion, it would have to have the same number multiplied to it. Hope this helps!
We are trying to find the average speed of the plane, which is mph, or 
. Using proportions, we can find the average speed of the plane in mph:
- Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that
.
- Multiply the entire equation by
- Divide both sides of the equation by
to clear both sides of the mile unit
The average speed of the plane is 300 mph.
Express 0.31 as a fraction and express 0.2 as a fraction
Area= 1/2 base x height
Area= 1/2 8x5
Area= 40/2
Area= 20cm^2
