Hi there.

If you want to find out the total, just multiply the rate per hour ($32.50) by the time (15 hours)

32.5 · 15 = $487.50

51 times the difference between a number and 21 is equal to the number plus 58.
Lerok [7]

51(x - 21) = x + 58

<em><u>Distributive property</u></em>

51x - 1071 = x + 58

<em><u>Subtract x from both sides</u></em>

50x - 1071 = 58

<em><u>Add 1071 to both sides</u></em>

50x = 1129

<em><u>Divide both sides by 50</u></em>

x = 22.58

A disc has a diameter of centimeters while a mini disc has a diameter of centimeters. Write the ratio of the mini disc diameter
Dafna1 [17]

Answer:

2 : 3

Step-by-step explanation:

A disc has a diameter of 21 cm while a mini disc has a diameter of 14cm. Write the ratio of the mini disc diameter to the disc diameter.

Answer: Let the diameter of the mini disc be d_1 while the diameter of the disc be d_2. To get the ratio of the mini disc diameter to the disc diameter, we just simply have to divide the diameter of the mini disc by the diameter of the disc and then represent the fraction in ratio form. The ratio of the disc diameters is given by:

Ratio of the mini disc diameter to the disc diameter = Diameter of mini disc / diameter of disc

Ratio of the mini disc diameter to the disc diameter = \frac{14}{21}=\frac{2}{3}

Ratio of the mini disc diameter to the disc diameter = 2 : 3
