Answer:
<h2>Width = 7.6 ft.</h2><h2>Length = 12.7 ft.</h2>
Step-by-step explanation:
Perimeter of a rectangle (P) = 2L + 2W
where
P = 40.6 ft.
L = 2W-2.5
plugin values into the formula:
40.6 = 2(2W-2.5) + 2W
40.6 = 4W - 5 + 2W
40.6 + 5 = 6W
W = 45.6 / 6
W = 7.6 ft.
L = 2W-2.5
L = 2(7.6) - 2.5
L = 12.7 ft.
proof:
P = 2(12.7) + 2(7.6)
P = 40.6 ft.
Answer:
a) The blue whale has about 200 times more mass
Step-by-step explanation:
(blue whale mass)/(cow mass) = (1.8×10^5 kg)/(9×10^2 kg)
... = (1.8/9)×10^(5-2)
... = 0.2×10^3
... = 200
The blue whale has about 200 times as much mass as a cow.
Answer:
Both Amy and Fraser walk distances equal to the radius of the lawn.
Step-by-step explanation:
The radius of a circle is a line segment from the center to the outside edge (circumference).
Amy walks from O, the center, to A, along the outside edge, using segment OA. This is a radius of the circle.
Fraser walks from O, the center, to B, along the outside edge, using segment OB. This is a radius of the circle.
Thus the correct answer is that both Amy and Fraser walk distances equal to the radius of the lawn.

Answer:
f(-2) = +2
Step-by-step explanation:
Let x = -2
So,
f(x) = 4x + 10
Substituting the value of x gives ,
f(-2) = 4 × (-2) + 10 = 10 - 8 = 2
