Answer:
C is the most reasonable answer because to add the system of equations together, you must make sure that one of the terms (whether it be the x or y value) can cancel out.
Step-by-step explanation:
The diameter is equal to the radius multiplied by 2.
Answer:
Option A.
Step-by-step explanation:
step 1
Find the area of the brownie pan
The area of the trapezoid is equal to
step 2
To calculate the number of days, divide the total area of the brownie pan by 30 square centimeters of brownie
so
First, determine the circumference (C) of the circle, the equation,
C = 2πr
Substituting the value or the radius,
C = 2π ( 4) = 8π
The arc length is the product of the circumference and the ratio between the subtended angle and 360. The mathematical expression is already,
S = (8π) x (72 / 360) = 0.8π
Thus, the arc is 0.80π.
