Answer: d. The helicopter rotor will spin 36,000 times in 1 hour
Step-by-step explanation:
Option A is wrong because in 40 minutes the rotor will spin:
= 40 * 600
= 24,000 times
Option B is wrong because we cannot know the number of times the rotor will spin before being lifted off of the ground with the details given.
Option C is wrong because in 3 hours the rotor will spin:
= 600 * 3 * 60 minutes
= 108,000 times
Option D is correct because in 1 hour the rotor will spin:
= 600 * 1 * 60 mins
= 36,000 times
Answer:
Isosceles triangle
Step-by-step explanation:
A triangle that contains 2 equal sides but one side different
Answer:
530.66 cm²
Step-by-step explanation:
take half the diameter of 26 and that gives you the radius of 13
A =π· r²
A = 3.14 x 169
Any number is equal to that number over 1
So x is equal to x/1
Same thing with 24. 24 = 24/1
To get it into percent we multiply by 100 so:

And simplifying that we get

And x/100 = x%
so 2400/100 = 2400%
So your answer is
<em><u>2400%</u></em> :)
