Answer: Find the formula and there you go
Step-by-step explanation: Each 4 papers = 3 minutes keep adding it until I get near twenty one and don't go over
Answer:
10 and 31/100
Step-by-step explanation:
C = 18
because find the radius by dividing by pi and square-rooting, then multiplying the radius by 2 to get the diameter. Then multiply by pi to get the circumference
It's 65. Because you add the other angles and get 90+25 and get 115. 180 -115 = 65.
Hi there!
We can solve by setting both equations equal to each other:
.5x + 4 = -.25x² + 5
Move everything to one side:
0 = -.25x² - .5x + 1
Multiply both sides by 4 to cancel out the decimals:
0 = -x² - 2x + 4
Factor out negative from both sides:
0 = x² + 2x - 4
Use the quadratic formula:
Plug in the corresponding terms:
Simplify:
Simplify the radical to reduce:
Divide all terms by 2:
