Answer:
c. 56.2 mph
Step-by-step explanation:
In most cars, the speedometer reading is proportional to tire rotation speed, so a larger diameter tire will go farther for the same number of rotations. That is, the distance traveled in a certain length of time is proportional to the tire circumference, which is proportional to the tire diameter.
The car with new tires will actually be going at the speed of ...
(26 in)/(24.5 in) × (53 mi/h) ≈ 56.245 mi/h ≈ 56.2 mph
Answer:
15
Step-by-step explanation:
the diagonal of a rhombus are perpendicular, so we can use the Pythagorean theorem to solve this problem:
CL = √17^2 - 8^2 = √289 - 64 = √225 = 15
Answer:
129
Step-by-step explanation:
8^2 + 9 (12/3 x 2) -7 Parentheses first 12 : 3 is the same as 12/3
8^2 + 9 (4x2)-7 Parentheses:
8^2 + 9 (8) - 7 Exponent 8 x 8:
64 + 9(8) - 7 Multiply:
64 + 72- 7 Add :
136 - 7 Subtract:
129
The answer is 129.
Hope this helps :)
Answer: 4 * (12.75 + x) = 61
Step-by-step explanation:
Each of the 4 friends paid $12.75 so that is:
= 4 * 12.75
Assuming the tip is denoted as x it would be:
= 4x
Putting them together is:
4 * (12.75 + x) = 61
Solving the equation would give:
4 * (12.75 + x) = 61
51 + 4x = 61
4x = 61 - 51
x = 10/4
x = $2.50
Answer:
It is 6/8
