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!!!! : )
Answer:
y-8=3/2(x+4)
Step-by-step explanation:
y-y1=m(x-x1)
y-8=3/2(x-(-4))
y-8=3/2(x+4)
It's C and A since .2 times 30 is 6 and 1/5 is also .2
Answer:
620
Step-by-step explanation:
100% must be the the answer so 700% must be 7 times that number.
4340÷7=620
Answer:
D) 3768 inches
Step-by-step explanation:
Given,
No. of plates = 100
Diameter of each plate = 12inches
So, radius of each plate = 12 / 2 = 6 inches
So, circumference of each plate
= 2 × 3.14 × 6 inches
= 37.68 inches
Hence, circumference of 100 plates = 100 × 37.68 inches
= 3768 inches
Hence, <u>3768 inches</u> of gold trim is required (Ans)
