13)
there are 2π radians in 1 revolution, and there are 60 seconds in 1 minute, so keeping that in mind, then,
14)
15)
what is the radians per seconds "w" in revolutions per minute? just another conversion like in 13)
Answer:
A
Step-by-step explanation:
area of triangle = 1/2*base*height
small triangle = 1/2*4*3 = 6
Big triangle = 1/2*8*6= 24
24/6=4
the big triangle is 4 times the size of the big triangle. so the small triangle would be 1/4 the size. hence D1/4(xyz) answer is A
30 is 20% of 150
Working out percentage problems of the form "30 is 20 percent of what number?"
We have, 20% × x = 30
or,
20/100 × x = 30
Multiplying both sides by 100 and dividing both sides by 20,
we have x = 30 × 100/20
x = 150
If you are using a calculator, simply enter 30×100÷20, which will give you the answer.
.10 because 1.10 - 1.00 = .10
The answer would be 32/5 or 6 2/5 or 6.4
Hope this helps
Have a great day/night
