If z varies jointly with x and y, x = 2 and y = 2, z = 7. Find z when x = 4 and y = 8.
Wittaler [7]

Answer:

56

Step-by-step explanation:

z varies jointly with x and y:

z = kxy

When x = 2 and y = 2, z = 7.

7 = k(2)(2)

k = 7/4

z = 7/4 xy

When x = 4 and y = 8:

z = 7/4 (4)(8)

z = 56

Functions A,B and C are linear functions. Some values of function A are shown in the table. Function B has y-intercept of (3,0)
cricket20 [7]

Answer:

In order of increasing slope:

B: y = 0

A: y = 2x-3

C: y = 3x+1

Step-by-step explanation:

(3,3), (5,7), and (6,9) are points on line A.

Use the coordinates of two of the points to find the slope of A.

Δy =7-9 = -2

Δx =5-6 = -1

Slope = Δy/Δx = 2

Equation for line of slope 2 that passes through (3,3):

y-3 = 2(x-3)

y = 2x-3

(3,0) and (5,0) are points on line B. They are horizontally aligned, so the equation for line B is y=0. Slope = 0.

You were given the equation for C: y = 3x+1. Slope = 3

In order of increasing slope:

B: y = 0

A: y = 2x-3

C: y = 3x+1

A major convention center, whose floors are covered by a square carpet tiles with side lengths of 9 inches laid out in a 48 by 9
bearhunter [10]

Answer:

option B

$28.80

Step-by-step explanation:

Given the question,

side length of one square tile = 9 inches

area of square tile = l² = 9² = 81 inches²

<h3>Step1</h3>

There are 48(96) = 4608 carpet tiles, so the company was making 4608($.05) = $230.40.

<h3>Step2 </h3>

Now, the company countered with square feet. We have a total of 4608(81) = 373,248 square inches.

1 square foot = 144 square inches.

373,248/144 = 2592 square ft.

2592($.10) = $259.20

$259.20 - $230.40 = $28.80
