The answer is 1 bag.

First, watch out, the units are different! Next, let's first calculate a volume of a box.
The volume (V) of the rectangular box is:
V = l × w × h
(l - length, w - width, h - height)

It is given:
l = 7 feet = 84 inches
w = 9 inches
h = 6 inches

Therefore,
V = 84 · 9 · 6 = 4.536 in³

We know that each bag of manure contains 2.625 cubic feet of manure.
2.625 ft³ = 4536 in³

Now, make a proportion:
If 1 bag contains 4536 cubic inches of manure, how many bags will fill the box of 4536 cubic inches:
1 : 4536 = x : 4536
⇒ x = 4536 * 1 / 4536 = 1

Therefore, only 1 bag of manure will fill the box completely.

Volume = 7 × 9 × 6
= 378 inches

box = 378 ÷ 2.625
= 144

Which inequality is shown in this graph

Katena32 [7]

ANSWER

$y \leqslant - 2x - 2$

EXPLANATION

The boundary line passes through (-2,2) and (0,-2).

The slope of this line is

$m = \frac{ - 2 - 2}{0 - - 2}$

$m = \frac{ - 4}{2} = - 2$

The y-intercept is , c=-2.

The slope-intercept form of this line is given by;

$y = mx + c$

We substitute values to obtain;

$y = - 2x - 2$

Since the lower half-plane is shaded the required inequality is

$y \leqslant - 2x - 2$

The cost to rent a van is $19.50 per day plus $0.25 per mile. If you have $157 to

Jobisdone [24]

Answer:

92 miles

Write an inequality for the total cost of the rental.

Cost of the rental = 19.50+0.25x<=44

where x is the number of miles driven.

Subtract 19.50 from both sides.

0.25x<=44-19.50

0.25x<=24.5

x<=24.5/0.25

x<=98
