It would be
A) 13 = 9 + 4
B) 7 - 4 = 3
and
E) 20 divided by 4 = 5
Since all of these values would match on each side of their respective equations after solving
ANSWER:
you multiply the meters by 100 to get to centimetres
you divide the centimetres by 100 to get to metres
REASONING:
100 centimetres= 1 metre
Answer:
40π/3 cm^2 ≈ 41.89 cm^2
Step-by-step explanation:
The centerline of the shaded region has a radius of 3cm+(4 cm)/2 = 5 cm. Its length is 1/3 that of the circumference of a circle with that radius (because 120° is 1/3 of 360°).
The area is the product of the centerline length and the width of the shaded area (4 cm).
shaded area = (1/3)(2π(5 cm))(4 cm)
shaded area = 40π/3 cm^2 ≈ 41.89 cm^2

<em>Alternate solution</em>
The area of the donut is the difference in the areas of the outer and inner circles:
πr₂² -πr₁² = π((7 cm)^2 -(3 cm)^2) = 40π cm^2
The are of the shaded region is (120°/360°) = 1/3 of that, so is
shaded area = (40/3)π cm^2
Answer:
B
Step-by-step explanation:
The second graph is the correct choice because the y-intercept is two, the graph is negative, and has a slope of m=3/1.
