15) Eileen has a piece of paper that is 30 cm long and 20 cm wide. She cuts out the shaded triangle as shown on the diagram.
What is the area of the triangle?
20 cm
30 cm
Not drawn to scale

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

how long did the flood last

step-by-step explanation:

then i will answer

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.

there would be 162.15 calories in this cereal.
