A rectangle has a perimeter of 56 cm and an area of 96cm^2. Its length is 4 more than five times its width. What is the lenght and width of the rectangle?
Answer:
L= 24cm
W= 4cm
Step-by-step explanation:
Given data
Perimeter= 56cm
Area= 96cm^2
Let the width be x
W= x cm
L= 5x+4
P=2L+2W
56= 2(5x+4)+2x
56= 10x+8+2x
56-8= 12x
48= 12x
x= 48/12
x= 4cm
L= 5x+4
L= 5(4)+4
L= 20+4
L= 24cm

A circular running track is 1/4mile long. Elena runs on this track, completing each lap in 1/20of an hour.
What is Elena’s running speed? Include the unit of measure.
Answer:
5 miles/hour
Step-by-step explanation:
the distance is the length of the track which is given as 1/4 of a mile. she completes each lap in 1/20 of an hour so divide the distance by the time taken to go around the distance
Answer:
Elena's speed is 5 miles/hour
Step-by-step explanation:
The speed is defined as the covered distance per unit time. The distance covered is the length of the circular track which is given as of a mile. We also know that she completes each lap in of an hour. To get her speed, we have divide the distance covered by the time taken to cover this distance and you come out with 5. She can run 5 miles each hour. Or in other words you take 20 divided by 4 you get 5
In what ways are the line of reflection and the line of symmetry the same?
Answer:
A shape has reflection symmetry if there exists a line of reflection that carries the shape onto itself. This line of reflection is called a line of symmetry. In other words, if you can reflect a shape across a line and the shape looks like it never moved, it has reflection symmetry.

Find the area of the figure.
Answer:
126.5
Step-by-step explanation:
Divide the shape into two, so you have a triangle and a rectangle.
Area of Rectangle:
A = bh
= (11)(8)
= 88
Area of Triangle:
A = 1/2bh
= 1/2(11)(7)
= 38.5
Add the two areas and the answer is 126.5
He measures and determines that he needs 24 feet of fencing. When he arrives at home improvement store, he realized fencing is priced at $0.25 per inch how much will it cost to fence it
Answer:
It will cost 72 dollars to fence the perimeter
Step-by-step explanation:
First of all, we will have to make sure that we are working with the same units.
To do this, we will have to convert our units which are given in feet to inches.
1 foot = 12 inches
24 feet = 288 inches.
We now have the total length of what he needs to be 288 inches.
The fence costs 0.25 dollars per inch.
Therefore 288 inches will cost 0.25 X 288 = $ 72

find
the value of x in 2x-7=5
Answer:
x = 6
Step-by-step explanation:
2x - 7 = 5
=> 2x = 5 + 7
=> 2x = 12
=> x = 12 / 2
=> x = 6
Hope it helps :)
Answer:
x = 6
Step-by-step explanation:
2x - 7 = 5
→ Add 5 to both sides
2x = 12
→ Divide both sides by 2 to isolate x
x = 6

Find the slope of the line y=1 over 6 x + 3 over 2
Answer:
1/6x
Step-by-step explanation:
the slope intercept form is: y = mx + b
m = slope
b = y-intercept.
When you already have in the form the slope is where m is, so the number that's is with x. In this case it's 1/6x.
Yani is creating a mural on a patio that measures 3 m long by 2 m wide. He is using 1 cm by 1 cm tiles. How many tiles will he need to use for the mural to cover the whole patio?
Answer: 60,000 tiles
Step-by-step explanation:
First find the area of the mural.
= 3 * 2
= 6 m²
The find the area of the tiles.
= 1 * 1
= 1 cm²
I m² = 10,000 cm²
There is therefore:
= 6 * 10,000
= 60,000 cm²
That is the area that needs to be covered in cm²
Seeing as each tile is 1cm², the number of tiles needed is:
= 60,000 / 1
= 60,000 tiles
Answer: the answer is 60,000 tiles
by the way that kinda seems like a lot of tiles to place like how long is that gonna take.

The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find all possible diameter lengths, d, if the circumference of a circle is more than 50 cm? 3.14 d less-than 50 3.14 d greater-than 50 50 d greater-than 3.14 50 d less-than 3.14
Answer:
3.14 d greater-than 50
(i also need help with one of my questions >~<)
Step-by-step explanation:
Since the circumference of a circle is approximately 3.14 times the length of its diameter, mathematically speaking:
C = 3.14d
That expression must be greater (>) than 50:
3.14 d > 50
So, the correct option is; 3.14 d greater-than 50

Is there a linear relationship between height and volume? Explain how you know.
Answer:
Yes
Step-by-step explanation:
The volume is for example the area of a circle times the height. If you divide the volume of a cylinder by the amount the radius is squared multiplied by pi, to calculate its height.
Yes, there exists a linear relationship between the height and the volume.
What is a linear relationship?A linear relationship is a relationship between the variables in a linear fashion. The relations ships can positive, negative, and neutral. Volume is a scalar quantity that is expressed in three-dimensional space.
Example of volume for the area of a circle is times the height. If we divide the volume of a cylinder by the amount of R it can be squared and multiplied by pi, to find its height.
Find out more information about the volume.
