Answer:
25%
Step-by-step explanation:
If we consider the original price of the piece of suit is x.
Given that, on Monday during a one day sale, the price of the suit was decreased by 20%.
Therefore, the new price of the suit on Monday is
.
Now, the price of the suit on Tuesday was changed back to the original price i.e. x.
Therefore, the price is increase by (x - 0.8x) = 0.2x from the price of 0.8x.
So, the percentage change in price of the suit on Tuesday is
%. (Answer)

GIVEN: A space telescope on a mountaintop is housed inside of a cylindrical building with a hemispheric dome. If the circumference of the dome is
, and the total height of the building up to the top of the dome is
.
TO FIND: what is the approximate total volume of the building.
SOLUTION:
let the height of the mountaintop be 
As the dome hemispherical.
circumference of a hemisphere 



total height of the building up to the top of the dome 


Volume of building 

as radius of mountain top is same as dome
putting values


Hence the total volume of the building is
Hello,
spinner has 1 yellow, 2 red, 3 blue and 2 green sections. What is the probability of not getting a yellow?
to find the probability to not get a yellow you have to know the total of color which is
1+2+3+2=8
and its 1 yellow
So the probability of not getting a yellow is 1/8
hope this help

Answer:
l = 16, w = 8
Step-by-step explanation:
Let l = length
Let w = width
Area = w * l
128 = w * l
w = 128/l
Perimeter = 2w + 2l
48 = 2w + 2l
48 = 2(128/l) +2l
48 = 256/l +2l
Multiply everything by l
48l = 256 + 2l^2
l^2 + 128 = 24l
l^2 + 128 -24l = 0
(l-16)(l-8)= 0
L = 16
L = 8
If you try them out, and test it, l = 16 would work:
2(16) + 256/16 = 48
32 + 16 =48
16 * 128/16 = 128
16 * 8= 128
128 = 128
Since I'm not sure if you are in advanced math or not, I will do it simple with guess and check
