Answer:
120 Minutes
Step-by-step explanation:
24 minutes / 2 miles = 12 minutes / 1 mile
12 minutes / 1 miles = x minutes / 10 miles
Cross multiply
12*10/1 = x
120 / 1 = x
x = 120

Find the value of d and FG if:
Answer:
The value of x = 8.5
The value of FG = 8.5 units
Step-by-step explanation:
Given
F is between E and G.EF = 7FG = 2(x - 5)EG = 3(x-4)Determining the value of x
As F is between E and G, so
EF = FG
7 = 2(x-5)
7 = 2x-10
2x = 7+10
2x = 17
divide both sides by 2
2x/2 = 17/2
x = 8.5
Thus,
The value of x = 8.5
Determining the value of FG
As
FG = 2(x-5)
substituting x = 8.5
FG = 2(8.5 - 5)
FG = 2(3.5)
FG = 7
Thus,
The value of FG = 8.5 units
Summary:
The value of x = 8.5
The value of FG = 8.5 units

The following data represents the 2011 guaranteed salaries (in thousands of dollars) of the head coaches of the final 8 teams in the 2011 NCAA Men's Basketball Championship.

(Source: www.usatoday.com)
1950 434 2300 3575 3376 3800 1655 418
Compute the range, variance and standard deviation for these data.
Round your answers to the nearest integer, where appropriate.
Answer: Range = 3382
Variance = 1785193
Standard Deviation = 1336
Step-by-step explanation: Range is the difference between the highest value and lowest value of the set.
Range for the coaches salaries is
range = 3800 - 418
range = 3382
Variance and Standard Deviation are both the statistical measures of the spread between in the data set. In other words, they show how far the numbers in the set are from the mean of the data.
Variance is calculated as
[tex]s^{2}=\frac{\Sigma (x-\mu)^{2}}{n}[/tex]
x are the numbers in the set
μ is the mean
n is sample or population quantity
For the coaches' salaries, variance is
[tex]s^{2}=\frac{\Sigma (418-2188.5+...+3800-2188.5)^{2}}{8}[/tex]
s² = 1785192.6
Standard deviation is the squared root of variance:
[tex]s=\sqrt{s^{2}}[/tex]
Then, for coaches' salaries:
[tex]s=\sqrt{1785192.6}[/tex]
s = 1336.11
For the 2011 coaches' salaries, range, variance and standard deviation are 3382, 1785193 and 1336, respectively

Divide both sides by-3
p = 5
Graph the line.
y=3x
How do you graph that?
-- i have attached a picture of the graph
- in order to graph, plug in values for x and find y
- this would create order pairs which you will plot.
some order pairs:
(0,0)
(1,3)
(2,6)
Answer: Plot the two points (0,0) and (1,3). Draw a straight line through them. The graph is shown below.
===========================================================
Explanation:
When x = 0, we have y equal to...
y = 3x
y = 3*0
y = 0
So this means (x,y) = (0,0) is one point on the line
Let's follow those steps for x = 1
y = 3x
y = 3*1
y = 3
So the point (x,y) = (1,3) is also on the line.
You can repeat this process for any x value you want; however, we only need two points to form the line. Plot (0,0) and (1,3). Then draw a straight line through both points. Extend the line as far as you can in either direction. This forms the graph of y = 3x.
You can use a graphing calculator (eg: TI83) to get the job done. Or you can use a free online resource such as GeoGebra or Desmos. I prefer GeoGebra as it offers more options. The graph shown below was made with GeoGebra.
Note that moving from point A(0,0) to B(1,3) has us move up 3 and over to the right 1. This is due to the slope of 3 = 3/1.
y = 3x is the same as y = 3x+0. It is of the form y = mx+b with m = 3 = 3/1 as the slope and b = 0 as the y intercept.

Answer:
$374,080.00
Step-by-step explanation:
You want to calculate the interest on $40000 at 5.8% interest per month after 12 year(s).
The formula we'll use for this is the simple interest formula, or:
[tex]I=P*R*T[/tex]
Where:
P is the principal amount, $40000.00.
r is the interest rate, 5.8% per month, or in decimal form, 5.8/100=0.058.
t is the time involved, 12....year(s) time periods.
Since your interest rate is "per month" and you gave your time interval in "year(s)" we need to convert your time interval into "month" as well.
Do this by multiplying your time, 12 year(s), by 12, since there's 12 months in 1 year.
So, t is 144....month time periods.
To find the simple interest, we multiply 40000 × 0.058 × 144 to get that:
The interest is: $334080.00
Usually now, the interest is added onto the principal to figure some new amount after 12 year(s),
or 40000.00 + 334080.00 = 374080.00. For example:
If you borrowed the $40000.00, you would now owe $374080.00
If you loaned someone $40000.00, you would now be due $374080.00
If owned something, like a $40000.00 bond, it would be worth $374080.00 now.

y = 9x + 28 & y = 11x + 22
Answer:C.4
Step-by-step explanation:
Answer:
It's B.3
Step-by-step explanation:
Substitution. With the equation Y= 9x+28 and Y= 11x+22, you substitute the x-factor with '3'. Which will give you
Y= 9(3)+28 Y= 11(3)+22
Y= 27+28 Y= 33+22
Y= 55 Y= 55

Aria´s height is 3 inches less than her brother´s height. her brother´s height is unknown.
The answer is x-3. We don't know the brother's height, so we make it into a variable. You may pick any variable, but x is a common choice. We then subtract 3 from x, which would give us Aria's height. Since we don't know the height of the brother, we won't know Aria's height.

Distributive property means
Answer:
according to
Step-by-step explanation:
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
