Answer:
The answer is 78.5
Step-by-step explanation:
If you subtract -8 by -3 you get 5, which is the radius. If you plug that into the equation you get 78.5.
<span>The sum of two numbers is 48.
a + b = 48
;
If one third of one number is 5 greater than one sixth of another number,
a = b + 5
multiply both sides by 6, cancel the fractions
2a = b + 30
2a - b = 30
</span><span>use elimination to solve this
a + b = 48
2a - b =30
-------------Addition eliminates b, find a
3a = 78
a =
a = 26
then
26 + b = 48
b = 48 - 26
b = 22</span>
Answer:
125 = 5 * 5 * 5 = 5^3
Step-by-step explanation:
125 is equal to 5 times 5 times 5, and a power is a way to write repeated multiplication, just by saying what number it is and the putting a ^ sign and then saying how many times there is that number. There is 5 three times, so the power is 5^3.
Answer:
2
Step-by-step explanation:
Using a calculator, determine the value of √101 to four or five decimal places. Do the same with 10π. We get { 9.92749, 10.0500, 0.99853, 31.4159}.
Arranging these in descending order, we get {10π, √101, 9.92749, 0.99853}.
