There are two equation of the system
(1) The perimeter
2(w + l) = p
2(w + l) = 86
(2) The length and the width
2w = l + 2
From the second equation
2w = l + 2
l + 2 = 2w
l = 2w - 2
Subtitute l with 2w - 2 in the first equation to find the width
2(w + l) = 86
2(w + 2w - 2) = 86
2(3w - 2) = 86
6w - 4 = 86
6w = 90
w = 15
Now, find the length by subtituting w with 15
l = 2w - 2
l = 2(15) - 2
l = 30 - 2
l = 28
The dimension of the rectangle
length = 28 cm
width = 15 cm

A cylinder and a cone have the same volume. The cylinder has radius x and height y. The cone has radius 1/3x. Find the height of the cone in terms of y.
Great question! I had this question in Geometry on Edmentum.
Answer: Height of cone = 3y
Step-by-step explanation:
We know that the cylinder and the cone have the same volume. The cylinder has radius x and height y. We will make use of the formulas:
Volume of cylinder = πr²h
Volume of cone = 1/3πr²h
Since the cone has radius 1/3x, we will have to make its height 3 times of y (the height of the cylinder) to make both the cylinder and the cone have the same volume.
So, the height of the cone is equal to 3y.

is 42.1 greater than 24.1
Answer:
Yes!
Step-by-step explanation:
42.10 is the same as 42.1 and 24.10 is the same as 24.1. Once you added the zero (which isn't needed), it'll be easier to compare them
42.10 < 24.10
Answer:
Yes!
42.1>24.1

SHOW ALL OF WORK. Find missing length, round to the nearest tenth if necessary.
Answer:
15
Step-by-step explanation:
to do this you need to use the Pythagorean theorem
a^2+b^2=c^2
9^2+12^2=c^2
81+144=c^2
[tex]\sqrt{225}[/tex]=[tex]\sqrt{c^2}[/tex]

Look here in a square which is what I imagine that drawing is all the angles are 90 degrees. A rectangle would be knowing two angles is know all of them one way or another so fix your work and you should know the answer
Answer:
x = 200
Step-by-step explanation:
A rectangle (and any parallelogram) will always equal 360 degrees in angles. Technically, every angle has to equal 90 degrees for it to be a rectangle, just a side note.
Thus, 60 + 30 + 70 + x = 360
Solve for x.
60 + 30 + 70 + x = 360
160 + x = 360
x = 360 - 160
x = 200
PLEASE HELP ME BRAINLISET FOR RIGHT ANSWER!!
Answer:
1. No, Student 1 did not make any errors. However, their use of a ruler, or lack of thereof, could result in a lack of accuracy.
2. The student manually found the points and connected them together, doing so for both A and B and thus finding the intersection.
3. Since there is no formula used, the result may not be accurate. The student can only guess the position of the intersection, not know exactly (i.e. when the points are positioned at decimal numbers.)
Answer:
for answer 1 its no
for 2 the person found the points and connected them
for 3 no formula so its not accurate

I WILL GIVE BRAINLIEST FOR FULL PROOF! no trolls!!!
Answer:
AE = CF .
Why?
BD acts as a shape bisector because it cuts the entire rectangle in half from points B and D.
Given that AE is perpendicular to BD, and CF is perpendicular to BD (which we know BD is a bisector), that means that both AE and CF are of equal length inside the rectangle.
Another way to look at it is:
AE = CF because they are technically just vertical angles, shifted and displaced in a weird way; it is a different representation of vertical angles, only distorted. (Don't use this as your answer though, it needs more context. I just want to make it look easier to comprehend.)
