While attending a school carnival, you estimate the ratio of children to adults as If there are 180 people at the carnival, about how many children are in attendance?

180-n_c

Step-by-step explanation:

Given that the ratio of children to adults is 2:1.

Let and be the number of children and adults in the school carnival.

So,

Given that the total number of peoples in the carnival =180

So,

Now, from equations (i) and (ii), we have

Hence, the number of children in attendance is 120.

answer: the answer is 127 degrees

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.
