B 12:3 = 4-1=3 C 10- 7=3 And A 2+15x=x=15-2=13
Answer:
∠ A = 50°
Step-by-step explanation:
In a parallelogram, consecutive angles are supplementary, sum to 180°
∠ A + 130° = 180° ( subtract 130° from both sides )
∠ A = 50°
Answer:
Peanut oil freezes at a higher temperature than olive oil because 3.1 °C > –6.1 °C.
Step-by-step explanation:
Well since 3.1 is greater than -6.1 then it should be Peanut oil freezes at a high temperature. I did the test and I got it right. I hope you do to. :)
Exact Area = 98pi
Approximate Area = 307.8760800518 (use calculator stored version of pi)
Approximate Area = 307.72 (using pi = 3.14)
Units are in square millimeters
======================================================
Explanation:
In 60 seconds, the hand sweeps out a full circle of radius 14. The area of this circle is
A = pi*r^2 = pi*14^2 = 196pi
Half of this is what the hand sweeps out in 30 seconds, so A/2 = (196pi)/2 = 98pi is the exact area it sweeps out. Your calculator would then show 98pi = 307.8760800518 approximately
If instead you use pi = 3.14, then the approximate area is 98*3.14 = 307.72
