Answer:
x=9
JKL = 108 degrees
KLJ = 27 degrees
LJK = 45 degrees
Step-by-step explanation:
Add all the values of the triangle angles together to get 20. Then divide 180 by 20 to get 9 (The sum of all the angles in the triangle always equals 180 degrees).
JKL = 12x = 12(9) = 108
KLJ = 3x = 3(9) = 27
LJK = 5x = 5(9) = 45

The fabric cost 7cents per square inch. She will only pay for the fabric used to cover the box, even if there is waste or extra. How much money did shyla spend on fabric? Is the box is 7 by 11by 8 inchs
Answer:
Shyla will pay about 63 cents to cover the box
Step-by-step explanation:
Length of the box ( l ) = 7 inches
Width of the box (b) = 11 inches
Height of the box (h) = 8 inches
We can solve this equation by following two simple steps.
1. The first step is to find the total surface area of the box. This is the total area that the decorative fabric will be covering.
We can get this by the following formula:
SA=2( length X width) +2( length X height )+2(height X width)
SA = 2( 7 X 11 ) + 2(7 X 8) + 2 (8 X 11 ) = 442 square inches
2. The second step is to divide the total surface area by the price of the fabric per square inch.
This will be 442 square inches divided by 7 cents per square inch = 63.14 cents
Shyla will pay about 63 cents to cover the box
Which equation has the greatest rate of change?
A.
y=2x+5
B.
y=x+6
C.
y= -5x+2
D.
y=2/3x+4

The required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
A dog walker charges a $ 30 sign-up fee to cover insurance costs and $ 27 per walk.
Let the total cost be t for the w walks.
So, the expression is given as,
t = 27w + 30
Where 27w represents the cost of w walks.
Thus, the required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

A point R (-2,5) is mapped to point R',as described by a translation of 6 units to the rights and 7 units down.Mark R' on the coordinate plane.
Answer:
(4, -2)
Step-by-step explanation:
Given a point R (-2,5), if the point R' is described by a translation of 6 units to the rights and 7 units down, then the coordinate of R' will be;
6 units to the rights is towards the positive x axis
7 units down is towards the negative y axis
R' = (-2+6, 5-7)
R' = (4, -2)
Hence the coordinate point of R' on the plane is (4, -2)

Tasha lists all the multiple of 3 from 3 to99. Tony lists all the multiples of 5 from 5 to100. What is the first number that is on both lists? The second.
Answer:
Multiples of 3 = 3, 9Multiples of 5 = 5, 10Step-by-step explanation:
In a list of 3 to 99, the first multiple of 3 will be none other than 3 itself because when multiplied by 1, you get three.
The second number will be: 3 * 2 = 6
In a list from 5 to 100, the first multiple will be 5 with 5 being a multiple of itself when multiplied by 1.
Second number = 5 * 2 = 10
A person on a moving sidewalk travels 24feet the in 7 seconds. The moving side walk has a length of 180 feet. How long will it take to move from one end to the other?
Given:
A person on a moving sidewalk travels 24 feet the in 7 seconds.
The moving side walk has a length of 180 feet.
To find:
Time taken by the person to move from one end to the other.
Solution:
A person on a moving sidewalk travels 24feet the in 7 seconds.
The speed of the person is
[tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]
[tex]\text{Speed}=\dfrac{24}{7}[/tex]
[tex]\text{Speed}=\dfrac{24}{7}[/tex]
The moving side walk has a length of 180 feet.
[tex]\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\text{Time}=\dfrac{180}{\dfrac{24}{7}}[/tex]
[tex]\text{Time}=\dfrac{180}{1}\times \dfrac{7}{24}[/tex]
[tex]\text{Time}=52.5[/tex]
Therefore, the time taken by the person to move from one end to the other is 52.5 seconds.

Answer:
D
Step-by-step explanation:
The basic equation to solve this would be D = RT, which is
D is Distance
R is Rate (speed)
T is time
To find total distance D, we can find individual distances for two legs of the whole.
First Leg:
R = 8
T = a
D = 8a
The length of a rectangle is six times its width.
If the perimeter of the rectangle is 84 ft, find its area.
The area of the rectangle is 216 square feet
How to determine the area?Let x represents the length and y represents the width.
So, we have:
x = 6y
So, the perimeter is:
P = 2(x + y)
The perimeter is given as:
P = 84
So, we have:
2(x + y) = 84
Divide by 2
x + y = 42
Substitute x = 6y in x + y = 42
6y + y = 42
Evaluate the sum
7y = 42
Divide by 7
y = 6
Substitute y = 6 in x = 6y
x = 6 * 6
x = 36
The area is calculated as:
Area = xy
So, we have:
Area = 36 * 6
Evaluate
Area = 216
Hence, the area of the rectangle is 216 square feet

right angled triangle 5 12 c
Start with: a2 + b2 = c2
Put in what we know: 52 + 122 = c2
Calculate squares: 25 + 144 = c2
25+144=169: 169 = c2
Swap sides: c2 = 169
Square root of both sides: c = √169
Calculate: c = 13
