Explanation:
P = 580 is the perimeter of the rectangleW = 144 is the widthL = unknown lengthThe units for each are in feet.
The formula tying together all three variables is
P = 2(L+W)
which is the same as saying
P = 2L+2W
We can think of it having two copies of L and two copies of W, four sides total, added together to get the full perimeter.
I'll go with the first version. Plug in the given values and solve for L
P = 2(L+W)
2(L+W) = P
2(L+144) = 580
L+144 = 580/2
L+144 = 290
L = 290-144
L = 146 feet is the length
---------------
We can confirm this by saying
P = 2(L+W) = 2(146+144) = 2*290 = 580
Or we could say
P = 2L+2W = 2*146+2*144 = 292+288 = 580
or,
P = L+W+L+W = 146+144+146+144 = 580

Step-by-step explanation:
Brian sat in a massage chair at a shopping mall for 8 minutes and paid $9. Norah sat in
the same massage chair for 12 minutes and paid $11. If the relationship between the
number of minutes and the amount paid is linear, with x representing the minutes and y
representing the amount paid in dollars, which of these equations models the situation?
A. x = 0.5y + 5
B. x = y + 1
C. y = 0.5x + 5
D. y = x + 1
Answer:
(1/2)x + $5 (Answer A)
Step-by-step explanation:
Two points on the line representing the cost are (8, $9) and (12, $11).
The change in x is 4 (minutes); this is the 'run.' The change in y is $2 (this is the 'rise'). Thus, the slope of this line is m = rise / run = $2/(4 min), or 1/2 dollar per min.
Applying the slope-intercept formula y = mx + b, we get:
$9 = (1/2)(8) + b, and from this we see that b must be $5.
Then the correct equation is y = (1/2)x + $5.

Which expression best represents the value of it? * The local pizza place has placed a new circular sign above the restaurant. The circumference of the sign is 37.68 feet, and the diameter is 12 feet. Which expression best represents the value of pi?
A.37.68/6
B.37.68/12
C.12/37.68
D.6/37.68
Answer:
B
Step-by-step explanation:
The circumference of a circle can be described as the linear distance round the circle
The circumference of a circle = 2πr or πD
π = 3.14
r = radius
d = diameter
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
π = circumference / 2r or circumference / D
37.68 / 12

The rectangle TV's width is determined by the formula W = 64.3 inches.
What is the diagonal of a rectangle?The formula determines a rectangle's diagonal.
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
Let D represent the diagonal of the rectangular TV.
D is now equal to 90 inches.
Let the TV's rectangle size be 63 inches.
Let W be the TV's rectangular width.
And , Diagonal of a Rectangle = √ ( Length )² + ( Width )²
D² = L² + W²
90² = 63² + W²
Subtracting 63² on both sides of the equation , we get
W² = 90² - 63²
On simplifying the equation , we get
W² = 4131
Taking square roots , we get
W = √4131 inches
W = 64.3 inches
Thus , W is equal to 64.3 inches.
Hence, the rectangular TV is 64.3 inches wide.

Answer:
∠ 1 = 37°
Step-by-step explanation:
(9x - 8) and (6x + 7) are corresponding angles and are congruent, then
9x - 8 = 6x + 7 ( subtract 6x from both sides )
3x - 8 = 7 ( add 8 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
Then
∠ 1 = 6x + 7 = 6(5) + 7 = 30 + 7 = 37°
