Given:
Perimeter of a parallelogram = 64 cm
Length = 3 times larger than the width
To find:
The length of the parallelogram.
Solution:
We know that, the perimeter of the parallelogram is:
Where, l is length and w is width of the parallelogram.
We have, l = 3w and P=64.
So,
Divide both sides by 8.
Now,
Therefore, the length of the parallelogram is 24 cm.
Answer:
The median is 115
Step-by-step explanation:
98, 104, 115, 137, 263
the median is the number in the middle when you sort from least to greatest
Answer:
9
Step-by-step explanation:
If you multiply 2 x 4 you get 8, then you divide 72 by what you got from the other 2 numbers when multiplied which in this case is 8 to get the final answer of 9.

Answer: 100 revolutions</h3>
This value is approximate because pi = 22/7 is approximate.
===========================================================
Explanation:
Let's find the perimeter of the wheel, aka the circumference
C = pi*d
C = (22/7)*77
C = 242
The distance around the tire is approximately 242 cm
At first glance, it looks like one revolution will do the trick. However, we need to cover 242 meters and not 242 cm.
We can say the following
1 meter = 100 cm
242 meters = 24200 cm .... multiply both sides by 242
One revolution covers 242 cm, which is 1/100 of the distance we need to cover. So that means we need to do 100 revolutions to get to the target we're after.
1 revolution = 242 cm
100 revolutions = 24200 cm ... multiply both sides by 100
---------------------------
We could also use a proportion to solve
(1 revolution)/(242 cm) = (x revolutions)/(24200 cm)
1/242 = x/24200
1*24200 = 242x
242x = 24200
x = 24200/242
x = 100
False, to get pi is pi= circumference divides by diameter
