Arc length is s=r x theta. The unit circle has r=1 so for an arc length of 3pi/2 the angle is 3pi/2 radians
100% = 1
Because:to have 100 percent of something, you must have one whole. One whole equals 100% and the same backwards. I hope this helps!
So, the correct answer is equals =
Answer:
26.55
Step-by-step explanation:
When rounding to the nearest whatever, you always look at the digit to the right of it. In this case, you look at the thousandth digit. 3 is not equal to or less than five, so you round 3 to 0 and you get 26.55
Answer:
EF is 16.
Step-by-step explanation:
So we know that Point E is somewhere on Line DF. In other words, DE plus EF must equal DF. In an equation, this is:

We are given that DE is 2x, EF is 2x-6, and DF is 3x+5. So, substitute:

Now, solve for x.
On the right, combine like terms:

Subtract 4x from both sides:

Subtract 5 from both sides:

Divide both sides by -1:

Now that we know x is 11, substitute this back into the equation for EF to find EF.

Substitute 11 for x:

Multiply:

Subtract:

And we're done!
