In an open relay race joe planned to swim 3 2/5 laps and eric planned to swim 2 1 and 1/5 laps how many combined laps did joe and eric plan to swim

5 3/5

Step-by-step explanation:

The wording "combined laps" means you want the sum of the two numbers of laps. You can add their integer parts and their fractional parts.

... (3 2/5) + (2 1/5) = (3 + 2) + (2/5 + 1/5)

... = 5 + 3/5 = 5 3/5

The fractions add to less than 1, so no additional work is necessary.

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

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.
