Answer:
W=A/L
Step-by-step explanation:
If the area of the rectangle is L*W, you can just rearrange the equation A=L*W to get W=A/L, an equivalent equation.
Answer:
Step-by-step explanation:
In trapezoid FPST, FP=ST, then this trapezoid is isosceles, so
Draw the height PH. Triangle FPH is right triangle with two angles of measure 45°. This means that FH=HP. By the Pythagorean theorem,
Since trapezoid FPST is isosceles, the base FT hasthe length
Then the length of the midline is
Answer:
-2
Step-by-step explanation:
x^2 = 5 + (1/2)x
x^2 - 0.5x - 5 = 0
x = 5/2
x = -2
Answer: you can use 260 min, 60 min at a fixed price ($20) and extra 200.
Step-by-step explanation:
C(x) = 20 + 0.20(x − 60)
C(x) ≤ 60
20 + 0.20(x − 60) ≤ 60
0.20(x − 60) ≤ 60 - 20
0.20x - 12 ≤ 40
0.20x ≤ 40 + 12
0.20x ≤ 52
x ≤ 52/0.2
x ≤ 260
This way, you can use 260 min, 60 min at a fixed price ($20) and extra 200.
