Answer:
Step-by-step explanation:
Find a common denominator or greatest common factor. 63 and 27 are both multiples of 9. When you divide each by 9 you get 7:3. 14 and 6 are both multiples of 2. When you divide each by 2 you get 7:3 again. So these ratios are equivalent.
Start with any set of numbers. Multiply them each by the same factor and the new set will be an equivalent ratio.
They're all equal. They would all be $87.
To find, divide each price by the number of tires.
This one is easy if u look at the pattern u would see it would be 4
Total number of rotations that will be needed for the car to complete 10000 miles will be given by:
rotations=(distance)/(circumference)=10000/(86.4×1.57828×10^-5)
=7333346.475 rotations
Answer:
∠ KLM = 27°
Step-by-step explanation:
∠ KLM + ∠ NLM = 90 , that is
3x + 7x = 90
10x = 90 ( divide both sides by 10 )
x = 9
Thus
∠ KLM = 3x = 3 × 9 = 27°
