Answer: 8

Step-by-step explanation:

Given: Pedro cut a sheet of poster board into 10 equal parts.

let x be the total sheet.

then, one part of sheet= $\frac{1}{10}$ of the sheet

Now, His brother used some of the poster board and now 8/10 is left.

Therefore, if Pedro wants to make a sign from each remaining part of the poster board.

then, The number of signs he can make= $\frac{8}{10}\div \frac{1}{10}=\frac{8}{10}\times\frac{10}{1}=8$

Hence, Pedro can make 8 signs.

The graph represents the heights of two climbers on a climbing wall over a 12-minute time period.

pychu [463]

Both climbers rested on the wall at a constant height for 2 minutes.

<h3>How to determine the true statement?</h3>

The illustrative graph that represents the climbers' movement is added as an attachment

From the attached graph, we have the following observation

The line of Abby's movement is horizontal from x = 4 to x = 6
The line of Brynn's movement is horizontal from x = 5 to x = 7

The difference between the endpoints of both horizontal line is

Difference = 6- 4 = 2

Difference = 7 - 5 = 2

This means that both Brynn and Abby stopped for 2 minutes

Hence, the true statement about is that (d) Both climbers rested on the wall at a constant height for 2 minutes.

Write the augmented matrix for the system of linear equations.

ivanzaharov [21]

$\left[\begin{array}{cccc}-9&1&8&2\\0&-5&9&-7\\-3&-6&4&9\\-3&-8&1&0\end{array}\right|\left\begin{array}{c}-6\\6\\4\\-2\end{array}\right]$

Step-by-step explanation:

Given equations are

-9w +x+8y+2z = -6

-5x+9y-7z=6

-3w -6x +4y+9z = 4

-3w -8x+y = -2

Here the augment matrix for the system

$\left[\begin{array}{cccc}-9&1&8&2\\0&-5&9&-7\\-3&-6&4&9\\-3&-8&1&0\end{array}\right|\left\begin{array}{c}-6\\6\\4\\-2\end{array}\right]$

Matt is mailing a rectangular package at the post office the box's volume is 24 in.³ what are all of the possible dimensions len

Greeley [361]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

Volume = 24 in³

Process

1.- Find the prime factors of 24

24 2

12 2

6 2

3 3

2.- Volume of a rectangular package

Volume = length x height x width

3.- Possible values are, combine the prime factors to find the volume

Volume = 4 x 2 x 3 or

Volume = 2 x 4 x 3

Volume = 3 x 2 x 4

Volume = 2 x 2 x 6

Volume = 6 x 2 x 2

Volume = 2 x 6 x 2

Volume = 12 x 2 x 1

Volume = 1 x 12 x 2

Volume = 2 x 1 x 12
