Answer:

5 inches

Step-by-step explanation:

we know that

The scale drawing is

\frac{1}{4}\ in : 1\ ft

using proportion find out the width of the great room on her plan

\frac{(1/4)}{1}\ \frac{in}{ft}=\frac{x}{20}\ \frac{in}{ft}\\\\x=20(1/4)\\\\x=5\ in

A. What is the volume, in cubic feet, of the box in the diagram?
Allisa [31]

Volume is a three-dimensional scalar quantity. The number of boxes that can fit in the cargo hold of the truck is 54.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the box = Volume of the cube = a³ = (2.50)³ = 15.625 ft³

The volume of cargo hold = 7.50 × 7.50 × 15 = 843.75 ft³

Now, the number of boxes that can fit in the cargo hold of the truck will be,

Number of boxes = (Volume of truck container)/(Volume of box)

                              = 843.75/15.625

                              = 54

Hence, the number of boxes that can fit in the cargo hold of the truck is 54.

sveticcg [70]
4c + 3p = 10.93....multiply by 7
7c + 2p = 13.31....multiply by -4
--------------------
28c + 21p = 76.51 (result of multiplying by 7)
-28c - 8p = - 53.24 (result of multiplying by -4)
------------------add
13p = 23.27
p = 23.27/13
p = 1.79 <== cost of 1 pencil pack

1.79/10 = 0.179 rounds to 0.18 <== unit price per pencil

4x - 3y = 17 5x + 4y = 60 x = 2, y = -3 x = 5, y = 8 x = 8, y = 5 x = -8, y = -5
Anna35 [415]
4x - 3y = 17.....multiply by 4
5x + 4y = 60 ...multiply by 3
-----------------
16x - 12y = 68 (result of multiplying by 4
15x + 12y = 180 (result of multiplying by 3
-----------------add
31x = 248
x = 248/31
x = 8

4x - 3y = 17
4(8) - 3y = 17
32 - 3y = 17
-3y = 17 - 32
-3y = - 15
y = -15/-3
y = 5

solution is (8,5) <==
