Answer:
77
Step-by-step explanation:
Rate as BRAINLIEST
x + 9y
we plug in x and y
5+9(8)
=5+72
= 77
The straight edge of the semicircle is 4 units, as this is this the diameter.
The circumference of the full circle is
C = pi*d = pi*4 = 4pi
which is the distance around the full circle (aka circle's perimeter)
So half of this is 4pi/2 = 2pi
Add this onto the straight edge length to get 4+2pi as the exact distance around the entire semicircle. This includes both straight and curved portions.
If you use the approximation pi = 3.14, then 4+2*pi = 4+2*3.14 = 10.28 is the approximate answer. To get a more accurate answer, use more decimal digits in pi.
---------------------------------------------------------
In summary,
exact answer in terms of pi is 4+2pi units
approximate answer is roughly 10.28 units (using pi = 3.14)
Answer:
B.
Step-by-step explanation:
First, notice that we can cancel out an x in the second term. Thus:
As with the last question, change the sign to multiplication and "flip" the second term:
Multiply straight across:
Cancel the (x+1) term:
Cannot be simplified further.

Answer:
1,800$
Step-by-step explanation:
25% is 1/4th of the total amount. So...
Divide 2,400$ by 4 and get 600
Now, subtract 600 from 2,400.
