The actual length (l) of a rectangle is 27 centimeters. use the scale drawing of the rectangle to find the actual width (w).

Step-by-step explanation:

To solve this question, we just have to use proportions. The given rectangle is showing a ratio that helps a lot to find the answer. In other words, we can use the rule of three to solve this problem.

Now, we solve for :

Therefore, according to the proportion, the actual width is 18 centimeters.

When we use proportions and ratios like this problem, we have to make sure that we are placing magnitudes in the right order, that is, if we place width in the numerator, it always has to be in that position, placing the width in the denominator in the other ratio would be completely wrong.

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.
