The ratio of the areas of the two squares is 25 to 9. The side length of the smaller square is 30 meters. How long is the side l
Ratling [72]
Ratios of Area of the two squares = 25:9
So then let the areas be A1 = 25A and A2 = 9A, A is common element
Side of the smaller area S2 = 30 meters
Area of the smaller square A2 = 30 x 30 = 900
We have area of smaller square as 9A = 900 => A = 100
Area of the large square = 25A = 25 x 100 = 2500.
Hence S1^2 = 2500 => S1 = 50 meters which is 20 meters longer than the
side of the smaller square.

What changes occurred in the United States as a result of the cotton gin?
Jlenok [28]
While it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for slaves to grow and pick the cotton. In fact, the opposite occurred. Cotton growing became so profitable for the planters that it greatly increased their demand for both land and slave labor

PlEase explain where the decimal and zero comes in for 4840/90?
Anika [276]

Answer:

Read my explanation

Step-by-step explanation:

Since they both end with a 0, you can just cancel it out. So you'd have 484/9.

The answer to that is 53.7777777777...

So the decimal would come before the 3 and after the 7.

I hope this helped and have a good rest of your day!

Answer: Dealership 4: he would pay $40.33

Step-by-step explanation: I used a calculator, so if you have 1/3 you put 1 divided by 3 in your calculator and right that down somewhere completely

Then, you divide $121 dollars by the number you got for 1 divided by 3 and then multiply it by 121 and should get 40.3333333333 but you round to the nearest tenth so it would by 40.33

1÷3= 0.33333333333

121×0.33333333333= 40.3333333333
