A rectangle’s area and perimeter have the same numerical value. The length of the rectangle is 12 feet. What is the width of the rectangle in feet? Enter your answer as a decimal in the box.
Answer:
[tex]2.4\text{ feet}[/tex]
Step-by-step explanation:
A rectangle's perimeter is given by the formula:
[tex]P=2(l+w)[/tex]
A rectangle's area is given by the formula:
[tex]A=lw[/tex]
We are given that they have the same numerical value. In other words:
[tex]2(l+w)=lw[/tex]
And we are also given that the length is 12 feet. So, substitute 12 for l:
[tex]2(12+w)=12w[/tex]
To solve for the width, we just need to solve for w.
On the left, distribute:
[tex]24+2w=12w[/tex]
Subtract 2w from both sides. The left side cancels:
[tex]24=10w[/tex]
Divide both sides by 10. Flip also:
[tex]w=\frac{24}{10}[/tex]
Reduce both layers. Use 2. So:
[tex]w=12/5=2.4[/tex]
So, the width is 2.4 feet.
And we're done!

Melina graphed a line which passes through the points (-4, 2) and (6, 8). What is the slope of the line?
Answer:
The answer is
[tex] \frac{3}{5} \\ [/tex]Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-4, 2) and (6, 8)
The slope is
[tex]m = \frac{8 - 2}{6 + 4} = \frac{6}{10} = \frac{3}{5} \\ [/tex]
We have the final answer as

1) Find the value of X if m < EDG= 112 degrees
Answer:
x = 12
Step-by-step explanation:
From the question given above, the following data were obtained:
m < EDG = 112°
m < EDH = 6x – 9
m < HDG = 4x + 1
x =.?
Thus, we can obtain the value of x as shown below:
m < EDG = m < EDH + m < HDG
112 = 6x – 9 + 4x + 1
112 = 6x + 4x – 9 + 1
112 = 10x – 8
Collect like terms
112 + 8 = 10x
120 = 10x
Divide both side by 10
x = 120/10
x = 12
Therefore, the value of x is 12.

The cost per message is $0.15
What is unit rate?A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Given that, a graph,
The graph is showing a straight line,
Considering a coordinate (3, 20),
That means, they cost $20 for 3 messages.
Therefore, for 1 message = 3/20 = 0.15
Hence, the cost per message is $0.15

Answer:
18 square meters
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = 1/2(b1 +b2)h
The bases are the parallel line segments, and the height is the perpendicular distance between them.
A = (1/2)(7 m + 5 m)(3 m) = 1/2(12 m)(3 m) = 18 m^2
The area of the trapezoid is 18 square meters.

An athletic facility is building an indoor track. The track is composed of a rectangle and two semicircles.
a. Write a formula for the perimeter of the indoor track
P=
b. Solve the formula for x.
x=
c. The perimeter of the track is 660 feet, and r is 50 feet. Find x. Round to the nearest foot.
x=____feet
Answer:
(The image is not provided, so i draw an idea of how i supposed that the problem is, the image is at the bottom)
Ok, we have a rectangle of length x by r.
At the extremes of length r, we add two semicircles.
So the perimeter will be equal to:
Two times x, plus the perimeter of the two semicircles (that can be thought as only one circle).
The radius of the semicircles is r, and the perimeter of a circle is:
C = 2*pi*r
where pi = 3.14
Then the perimeter of the track is:
P = 2*x + 2*pi*r.
b) now we want to solve this for x, this means isolating x in one side of the equation.
P - 2*pi*r = 2*x
P/2 - pi*r = x.
c) now we have:
P = 660ft
r = 50ft
then we can replace the values and find x.
x = 660ft/2 - 3.14*50ft = 173ft

What is an absolute value of number?"It is the actual distance of the number from zero."
What is opposite of a number?"The opposite of number is a value which is an additive inverse of number.""The opposite of number 'a' is '-a'."For given question,
We need to find the statement which does not represent the same value as the others.
We find the value for each statement.
a) the distance between 0 and 9
The distance between 0 and 9 is 9.
b) the absolute value of negative 9
We know, |-9| = 9
So, the absolute value of -9 is 9
c) the opposite of 9
The opposite of 9 is -9.
d) the absolute value of 9
|9| = 9
So, the absolute value of 9 is 9.
Therefore, the statement that does not represent the same value as the others is 'the opposite of 9'

Hello i need help with 3/4(x+2) =6
Answer:
X = 6.
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
since you want to solve for x, you want to get it by itself
to start, you want to try to get (x+2) by itself, and you can do this by multiplying both sides by the reciprocal of 3/4
[tex](\frac{4}{3}) \frac{3}{4}(x+2) = 6 (\frac{4}{3})[/tex]
since a number multiplied by its reciprocal is equal to 1, this leaves you with
[tex](x+2) = \frac{24}{3}[/tex]
[tex](x+2) = 8[/tex]
now, you can subtract 2 from both sides in order to get x by itself
[tex](x+2)-2 = 8-2[/tex]
[tex]x = 8-2=6[/tex]
and then you have your answer
x = 6
hope this helps :)
