Answer:
≈ 452.5 rpm
Step-by-step explanation:
First convert mph to in/min.
35 mi/hr × (5280 ft/mi) × (12 in/ft) × (1 hr / 60 min) = 36960 in/min
The diameter of the wheel is 26 inches, so the circumference of the wheel is 26π inches. So the revolutions per minute is:
36960 in/min × (1 rev / 26π in) ≈ 452.5 rpm
Answer: 84.5 cm3
explanation: 1.3x13x5=84.5 cm3
hope this helps!
The answer should be C,
To solve this question, we have to use the rule of triangle inequality. This means, lengths of the any 2 sides of a triangle added up, must be longer than the remaining side.
Therefore, we can try and see which one of the options fits the rule.
A.
35+25 > 10 ✔️
25 + 10 = 35❌
A cannot make a triangle.
B.
15 + 10 > 5 ✔️
10 + 5 = 15 ❌
B cannot make a triangle.
C.
35 + 45 > 55 ✔️
45 + 55 > 35 ✔️
35 + 55 > 45 ✔️
C can make a triangle.
D.
25 + 25 < 75 ❌
D cannot make a triangle.
Therefore, the answer should be C.
