if you have a rectangular banner and the length is 44 inches and has a perimeter of 156 inches and an area of 1496 square inches. if i make a similar figure as the original banner with the length of 11 inches what is my perimeter and area?
Answers
1.) Finding the width and going from there
2.) Finding the scale factor
I would recommend using the scale factor technique. You see how the length is reduced by a factor of 4? Well since the perimeter's formula involves adding length times width, you can just multiply the perimeter by 1/4 since the length went from 44 to 11(Just a rule, take it by heart). That means that the perimeter is
The area is multiplied, not added, so you have to square the scale factor. This means multiply the area by 1/16 (Another rule, take it by heart). This means that the area is [tex]\frac{1496}{16} = between 94 and 95

Answer:
B
Step-by-step explanation:
We start with 16 grams of water
At the end of the first hour , we decreased by 3.5%
We take the amount and multiply by the percent decreased. Then subtract that from the original amount
16*3.5% =
16*.035 =.56
16-.56 = 15.44
At the end of the second hour , we decreased by 4.25%
We take the amount and multiply by the percent decreased. Then subtract that from the amount we started with at hour 2
15.44 *4.25%
15.44 *.0425=.6562
15.44-.6562=14.788
Answer:
B.
Step-by-step explanation:
So there are 16 grams initally. Then, the amount of water decreases by 3.5%.
So first we must find 3.5% of 16. 3.5% in decimal form is 0.035, since you divide 3.5 by 100. Then, when you multiply 0.035 by 16, you get 0.56. Since the solution decreased by that percentage, you must subtract 0.56 from 16, which is 15.44.
Then the amount of water decreases by 4.25%. That in decimal form is 0.0425. You multiply it by 15.44, and it comes out to 0.6562. You subtract that from 15.44, not 16, since some of the water has evaporated. So you get 14.7838.

This is the reason the mental method for both are similar. we can also use the same process for decimal numbers and whole numbers.
Answer: Using mental math to add with decimals is like using mental math to add whole numbers because the actual thing is we are adding the place values in both the cases and they different as in case of whole numbers we start from the ones place but in case of decimal numbers we first separate it into whole numbers and decimals to add by using mental math separately, after solving the sum we write both parts together and that is the answer.
For example to add 4.50+9.20
Take after decimal portion separately 0.50+0.20=0.70
and 4+9=13
write together it becomes 13.70.
so 4.50+9.20=13.70.
