(7/2) m is the width and 18m is the length. This is because area is lxw.let w= width and length=11+2wMultiply together, get 2w^2+11w-63=0factor to get (2w-7)(w+9).Find w and get w=7/2 and w=-9Negative rejected because a measurement can't be negative. Finally substitute that into the length equation (11+2w) to get 18m and width is 7/2 m

The perimeter of a rectangle whose sides are of lengths (4m+7) units and (3m+2) units
34kurt

Answer:

  • 2(4m + 7) + 2(3m + 2)

Step-by-step explanation:

<u>We know that:</u>

  • Length = (4m + 7)
  • Breadth = (3m + 2)

The perimeter of a shape is the sum of its boundaries. Let's represent perimeter as p.

<u>Solution:</u>

  • p = (4m + 7) + (4m + 7) + (3m + 2) + (3m + 2)
  • => p = 2(4m + 7) + 2(3m + 2)

Hence, the algebraic expression on how to find the perimeter is 2(4m + 7) + 2(3m + 2).

What are the cons of graphing, elimination, and substitution?
rosijanka [135]

GRAPHING CONS

1) hard to graph by hand. Often you need a graphics calculator or a computer software like maple or matlab. Or the graph has to be given.

2) hard to tell the exact solution, just by observing point of intersection. for example if x = 2.8675, the viewer would say x= 3.

3) sometimes not easy to decide the axis window of y and x axis. For example if the solution is very large like x = 100000 and your graph ends at x = 100, you cannot see the solution

SUBSTITUTION CONS

1) Becomes tedious if a system has too many equations or variables

ELIMINATION PROS/CONS

1) basically same as substitution

The data below indicate the time (in seconds) that it takes 25 separate employees to complete a certain task. hw1_q5.csva) What
IgorC [24]

Answer:

Explained below.

Step-by-step explanation:

Consider the data provided.

(a)

Compute the mean of the data in seconds as follows:

Mean =AVERAGE(array)

         = 225.280 seconds

(b)

Compute the median of the data in seconds as follows:

Median =QUARTILE.EXC(array,2)

            = 229 seconds

(c)

Compute the variance of the data in seconds as follows:

Variance =VAR.S(array)

              = 1148.043 seconds

(d)

Compute the standard deviation of the data in seconds as follows:

Standard deviation =STDEV.S(F2:F26)

                              = 33.883 seconds.

(e)

Compute the median of the data in minutes as follows:

Median =QUARTILE.EXC(array,2)

            = 3.755 minutes.

(f)

Compute the median of the data in minutes as follows:

Median =QUARTILE.EXC(array,2)

            = 3.817 minutes

(g)

Compute the variance of the data in minutes as follows:

Variance =VAR.S(array)

              = 0.319 minutes

(h)

Compute the standard deviation of the data in minutes as follows:

Standard deviation =STDEV.S(F2:F26)

                              = 0.565 minutes.
