Amanda ran 5 miles in 40 minutes and 30 seconds.
What was her minute per mile pace?

 8.1 minutes per mile

Work Shown:

40 minutes, 30 seconds = 40 + 30/60 = 40+0.5 = 40.5 minutes

She ran 5 miles in 40.5 minutes

This forms the ratio

5 miles : 40.5 minutes

Divide both sides by 5 to turn "5 miles" into "1 mile" and we get

5/5 miles : 40.5/5 minutes

1 mile : 8.1 minutes

Her minute per mile pace is 8.1 minutes per mile

This means it takes 8.1 minutes to run each mile.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
