Assuming that this is a circular pizza :P

The area of a circle is:

A=πr^2  divide both sides by π

A/π=r^2  take the square root of both sides

r=√(A/π), we are told that A=1386 so:

r=√(1386/π) cm

r≈21 cm  (to nearest hundredth of a centimeter)

What is the value of x in trapezoid ABCD
statuscvo [17]
So the trapezoid has 2 parallel sides making segments AD and BC  transversals

Therefore making angle c and angle b add up to 180

(180-3x) + 3x + 180-9x +9x

180 +12x = 360

180= 12x
x= 15

Write the expanded form of the decimal 0.082¯ using powers of 10
Softa [21]

Answer:

0.082 = 8.2× 10^-2

Step-by-step explanation:

Given the decimal number 0.082, the expanded form using the power of 10 can be gotten by writing the decimal number in standard format(writing as a multiple of 10).

To do that we will shift the decimal point to the front up to the front of digit 8. This shows that the decimal point will be shifted 2times to the front. Since of is shifted 2times to the front, our power of 10 will be -2.

0.082 = 8.2× 10^-2

This gives the required answer.

Note that, the power of 10 is positive when decimals are shifted to the back and negative when shifted to the front(in this case).

Help.. Suppose Q is the midpoint of PR
8090 [49]

Answer:

3x+41 or 38

Step-by-step explanation:

If Q is the midpoint of Line PR, then lines PQ and QR add up to equal Line PR. We then get

PQ=6x+25\\QR=16-3x\\PQ+QR=PR\\6x+25+16-3x=PR\\3x+41=PR\\

If you want to know the exact number that PR is, we can do additional steps where PQ = QR.

PQ=6x+25\\QR=16-3x\\PQ=QR\\6x+25=16-3x\\9x+25=16\\9x=-9\\x=-1\\\\3x+41=PR\\3(-1)+41=PR\\-3+41=PR\\38=PR\\PR=38
