A regular pentagon and rectangle have the same perimeter. The length of the rectangle and the side of the pentagon are equal. The width is 10 more than the length. Write an equation that describes the scenario. pentagon's perimeter: rectangle's perimeter: scenario's equation:
Answer:
Pentagon perimeter 5l
Rectangle perimeter 2l +2(l + 10
Scenario’s equation 5l=2l +2(l + 10)
Step-by-step explanation:trust me
The equation that describes the pentagon perimeter is 5l
Where l is the sides of the pentagon.
The equation that describes the rectangular perimeter is 4l + 20
Where l is the length of the rectangle
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Regular pentagon:
A regular pentagon has 5 sides.
Side = l
Rectangle:
Length = l
Width = 10 + l
Now,
The perimeter of a pentagon = 5 side
The perimeter of a rectangle = 2 (l + w)
The perimeter of the pentagon.
= l + l + l + l + l
= 5l
The perimeter of the rectangle.
= 2 (l + w)
= 2 (l + 10 + l)
= 2 (2l + 10)
= 4l + 20
Thus,
The equation that describes the pentagon perimeter is 5l
Where l is the sides of the pentagon.
The equation that describes the rectangular perimeter is 4l + 20
Where l is the length of the rectangle

Cypress Middle School wants to have a fundraiser to buy art supplies. Fundraiser A will give the school $1.50 for each order places plus $75 as a bonus. Fundraiser B will give the school $3.00 for each order placed, but no bonus. How many orders must be placed in order for the total amount of money earned by each fundraiser to be the same?
150
Answer:
The indifference point is 50 orders.
Step-by-step explanation:
Giving the following information:
Fundraiser A:
$1.50 for each order places plus $75 as a bonus.
Fundraiser B:
$3.00 for each order placed.
First, we need to structure the fundraisers' formula:
Fundraiser A= 75 + 1.5x
Fundraiser B= 3x
x= number of orders
Now, we equal both formulas and isolate x:
75 + 1.5x = 3x
75/1.5= x
50= x
The indifference point is 50 orders.
Prove:
Fundraiser A= 75 + 1.5*50= $150
Fundraiser B= 3*50= $150

Hudson and Knox are in a race. Hudson is running at a speed of 8.8 feet per second. Knox got a 30-foot head start and is running at a speed of 6.3 feet per second. How many seconds will it take until Hudson and Knox have run the same number of feet? Write the equation.
Answer:
It will take 12 seconds to be at same distance
The equation is;
8.8x = 6.3x + 30
Step-by-step explanation:
Let the number of seconds it will take be x
Mathematically, distance = speed * time
At x-seconds , Hudson will be at a distance of 8.8 * x = 8.8x ft
At x seconds , Knox will be at a distance of 30 ft + (6.3 * x) = 6.3x + 30feet
So the time it will take them to be at the same distance can be calculated using the equation;
6.3x + 30 = 8.8x
8.8x - 6.3x = 30
2.5x = 30
x = 30/2.5
x = 12 seconds
Answer:
Step-by-step explanation:
It will take 12 seconds to be at same distance

divide RS 1500 on the ratio of 2:3
Answer:
600:900
Step-by-step explanation:
Let the ratio be 2x+3x
2x+3x=1500
5x=1500
x=1500/5
x=300
2x = 600 ; 3x = 900
Therefore, 600:900 = 2:3
Andrew is evaluating his current financial position by totaling his monthly cash inflows and outflows. His cash inflows each month are $60 in allowance and $240 in wages from his part-time job working at the pet store. His cash outflows each month are $170 for his car payment, $70 in entertainment, and $45 for gas and food. How much, if anything, does Andrew have left over each month?
Answer:
Andrew has $15 left over each month
Step-by-step explanation:
Inflows=$240+$60=$300/mo.
Outflows=$170+$70+45=$285/mo.
Inflows-Outflows=left over
$300-$285=$15

Answer:
1. D2. CStep-by-step explanation:
1. .....................................................................................................
A. This is a functional relationship as the number of workers depend on the number of job sites.
y = 5xB. This is a functional relationship as the amount of money is dependent on the number of withdrawals
y = 2500 - 200xC. This is a functional relationship as the number of vitamins depend on the number of monkeys
y = 3xD. This is NOT a functional relationship as the output is a fixed value. The performance and scoring may repeat.

Find the x-coordinate of the vertex, y-coordinate of the vertex, and the x-intercepts.
! pls help, I’ll mark as brainliest !
Answer:
X=-1
Y=-9
Step-by-step explanation:
x^2+2x-8
x^2+2x +1 =8+1
(x+1)-9
x coordinate of vertex x=-1, y coordinate of vertex y=-9 and x=2 and x=-4 are the x intercepts.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given equation is y=x²+2x-8
then the x-coordinate of the vertex can be found using
x=-b/2a
x=-2/2=-1
x=-1 is the x coordinate of vertex.
substitute this value into f(x) for y coordinate
y=(-1)²+2(-1)-8
y=1-2-8=-9
y coordinate of vertex y=-9.
y intercept is -8.
To find the x intercepts x²+2x-8=0
x²+4x-2x-8=0
x(x+4)-2(x+4)=0
(x-2)(x+4)=0
x=2 and x=-4 are the x intercepts.
Hence, x coordinate of vertex x=-1, y coordinate of vertex y=-9 and x=2 and x=-4 are the x intercepts.
