Cam is playing four square on the playground with her friends. The area of the four square is 169 square feet. What is the side length of each player's square?

6.5 feet

Step-by-step explanation:

If total area is 169 square feet then we need to find 1/4 of that for each individual square. Each square is 42.25 feet square which would give a side length of 6.5 on each square.

6.5×6.5=42.25 area of each square

42.25×4=169 total area of all four squares

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.
