55. Joslyn eams money working part-time at a grocery store. This table shows the amounts of money that she earns for working different numbers of hours. Joslyn's Earnings
Number of Hours Worked 2 4 5. 12 Amount 62.50 125.00 | 150.00 Earned (dollars) $25.00 50.00 Part.

A Explain why the information in the table is a proportional relationship. As part of your explanation, determine the amount, in dollars, Joslyn earns per hour. Show your work.

Part B. Kate also has a part-time job.
• After working x hours, she earns y dollars • Her total earnings can be described by the equation y = 11.25x

Explain why Joslyn s total earnings will always be greater than Kate's total carnings when Joslyn and Kate work the same number of hours

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

step-by-step explanation:

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
