Corbin can shoot 24 baskets In 3 minutes. Which table best<br> represents this relationship?
seraphim [82]

Answer:

  • Table C

Step-by-step explanation:

<u>This is the proportional relationship:</u>

  • y = kx

<u>We have x = 3, y = 24, then k is:</u>

  • 24 = 3k
  • k = 8

<u>The table will look as:</u>

  • x = 1 ⇒ y = 1*8 = 8
  • x = 2 ⇒ y = 2*8 = 16
  • x = 5 ⇒ y = 5*8 = 40

Correct choice is C

Need Help Please, This One Is A Bit Difficult.

Answer: 432 units²

Step-by-step explanation:

The figure is composed by two trapezoids.

The formula for calculate the area of a trapezoid is:

A=\frac{h}{2}(B+b)

Where "B" is the larger base, "b" is the smaller base and "h" is the height.

Let be A_f the area of the figure, A_1 the area of the trapezoid on the left and A_2 the area of the trapezoid of the right. Then the area of the figure will be:

 A_f=A_1+A_2

A_f=\frac{h_1}{2}(B_1+b_1)+\frac{h_2}{2}(B_2+b_2)

Substituting values, you get:

A_f=\frac{16units}{2}(25units+4units)+\frac{10units}{2}(25units+15units)=432units^2

Vinil7 [7]
10% of 360.26 is 36.026 but that answer wouldn’t be it since cents are only in the tenths and hundredths places after the decimal, so you’d probably have to round it up to 36.03
