Answer:
1010
Step-by-step explanation:
There are a whole class of questions that rely on the method to this one.
First add up what you know
1270 + 1150 + 870 + 1450 = 4740
Now add on the 5th month (which you don't know. Call it x)
4740 + x
Divide by 5
(4740 + x)/5 = 1150 and that is your equation
Solution
Multiply both sides by 5
5*(4740 + x) / 5 = 1150 * 5
4740 + x = 5750
Subtract 4740 from both sides
4740 - 4740 + x = 5750 - 4740
x = 1010
Which seems kind of low, but that's what the numbers come to.
Answer: 46,000
Step-by-step explanation:
X2 is double the amount of x1
"The diameter is 10, therefore radius = 5. If arc length = 10, then angle = 10/5 = 2 radians 2 radians = 2/2pi = 1/pi of a complete circle.
Area of circle = pi * r^2 = 25pi.
Area of sector = angle * area of circle = 1/pi * 25pi = 25"
