Five runners ran a marathon before they used a new training program. The same five runners also ran a marathon after they went t

hrough the new training program. The following data represents the completion time of a marathon in minutes for each of the 5 runners before and after training with the new training program. The trainer wants to determine if the training program results in faster completion time of the marathon. (You can use Excel for solving this problem).
Runner Before After
1 110 94
2 88 81
3 84 82
4 94 88
5 108 97

Estimate the length of one side of a square floor, if the area is 320 square feet. Give the whole number that is closest to the
RSB [31]
Let us assume the length of a side of the square floor = x feet
Area of the square floor as given in the question = 320 square feet
Then
x^2 = 320
x^2 = (17.89)^2
Then
x = 17.89
   = 18 feet approx

From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the second option or option "B".

What is the equation in point slope form of the line that passes through the point (2,6) and has slope of 5?
sleet_krkn [62]
Firstly, you can use the slope and the first point to find a second point:
2 + 1 = x2 and 6 + 5 = y2 because the slope is 5/1. 
Next you can write the equation in point-slope form (remember point-slope form is y - y1 = m(x - x1):
y - 11 = 5(x - 3) 
Another equation would be B because B is the correct equation if you choose 2 as x2 and 6 as y2. 
Hope this helps!

Bobby has already ran 1 mile on his own, and he expects to run 1 mile during each track practice. How many track practices would
german

Answer:

In order to have ran 33 miles, Bobby would have to attend <em>32 track practices.</em>

Step-by-step explanation:

Solving this problem entails of uncovering the amount of track practices Bobby must attend in order to have ran 33 miles. Start by reading the problem carefully to break down the information provided.

You can see that Bobby has already ran one mile on his own. This is important to remember for later. The problem also states that he expects to run one mile at every track practice.

Setting up an equation will help us solve. Here is how we could set up the equation:

(<em>amount of miles already ran</em> = 1) + (<em>number of track practices</em> = x) = (<em>total miles to run</em> = 33)

1 + x = 33

The equation is now in place. You can solve this, or isolate <em>'x',</em> by using the subtraction property of equality. This means we will subtract one from both sides of the equation, thus isolating the variable.

1 + x = 33

1 - 1 + x = 33 - 1

x = 32

The variable is the only term left on the left side of the equation. This means Bobby must attend track practice <em>32 times</em> in order to have ran 33 miles.

The cube shaped box is 6 inches wide and the rectangular box is 10 inches long 4 inches wide and 4 inches high. How much greater
nasty-shy [4]

Answer:

Formula of the volume for a cube= s^3 (side, length, width, or edge is acceptable for s)

Formula of the volume for a rectangular prism= lwh (length*width*height)

<u><em>= 50 cubic in. more</em></u>

Step-by-step explanation:

cube: 6^3

6x6x6

36x6

216

rectangular prism: 10x4x4

10x16

160

cube - rectangular prism= Difference between cube and rectangular prism

216   -   160                      =  50

<em>*REMEMBER that when dealing with volume the units are cubic (whatever), in this case, its cubic inches(in^3).</em>
