Nikitich [7]

Answer:

The total sale price that Gechina paid was $5,274.71.

Step-by-step explanation:

Given that Gechina Galvez shopped at a department store during the end-of-summer sale in which all luggage was marked down 35 percent, and she purchased a suitcase that regularly sells for $74.95, a garment bag that regularly sells for $8,000, and a tote bag that regularly sells for $39.99, in order to know the total sale price, the following calculation has to be made:

100 - 35 = 65

(8,000 + 74.95 + 39.99) x 0.65 = X

8,114.94 x 0.65 = X

5,274.71 = X

Therefore, the total sale price that Gechina paid was $5,274.71.

a prism has a surface area of 100 cm2 . which sentence describes the effect of measuring the surface area in square millimeters
jok3333 [9.3K]

For this case we must make a conversion, to indicate the surface of the prism in square millimeters.

By definition, we have to:

1cm ^ 2 = 100mm ^ 2

By making a rule of three we have:

1cm ^ 2 ----------> 100mm ^ 2\\100cm ^ 2 ------> x

Where the variable "x" represents the quantity in millimeters.

x = \frac {100 * 100} {1}\\x = 10000 \ mm ^ 2

Thus, the surface of the prism is: 10000 square millimeters

Answer:

10000 square millimeters
