Answer:

answer b (0.73)

Step-by-step explanation:

"Triple" means to increase in size by a factor of 3.

Thus, B = (1 + r)^2 becomes

3 = (1 + r)^2. Our task is to determine the value of r, the annual interest rate.

Taking the square root of both sides, we get

√3 = 1 + r, which yields √3 - 1 = r.

This is approx. 1.732 - 1.000, or 0.732. Answer b) is closest.

erma4kov [3.2K]

In first 40 hours he earns = 7.30 x 40 = $292
Each hour after his rate = 7.20 x 1.5 = $10.80 per hour
In extra four hours he earns = 10.80 x 4 = $43.20

Total earnings = $292 + $43.20 = $335.20

What is the difference of the fractions? Use the number line and equivalent fractions to help find the answer.

ipn [44]

The difference of the fraction is $\mathbf{ -\dfrac{3}{4}}$ by using equivalent expressions.

<h3>What is a number line?</h3>

A number line is a diagrammatic representation of real numbers on the graduated line. It ranges from negative axis to positive axis with 0 being the center position.

A sketch showing the representation of the difference in the mixed fractions can be seen in the image attached below.

Using equivalent expressions to determine the difference between the mixed fractions, we have;

$\mathbf{ = -2\frac{1}{2} - (-1\dfrac{3}{4}) }$
