Ok so area is length times width. A square has the same sides all around, which is called a quadrilateral. So you would plug in 40 for length and width. 40x40= 1,600 cm^2 <———— is your answer.
Hope this helped :)
Answer:
5:7
Step-by-step explanation:
10:14 ----> reduce by 2
5:7
125/21 = 150/x
cross multiply
125x = 3150
x = 3150/125
x = 25.2 lbs....rounded up = 26 lbs <==
Answer:
-11, -1, 0, 6/5, 1.25
Step-by-step explanation:
To find whether or not the ratios are proportional, simplify. The first ratio is already simplified, so simplify the second one. to do this, find what factors 24 and 35 have in common.
Factors of 24: 1, 2, 3 ,4, 6, 8, 12, 24
Factors of 35: 1, 5, 7, 35
It looks like there are now common factors between 24 and 35. For the ratios to be proportional, they have to have the same value. If 24/35 can't be simplified to 4/7, the factors are not proportional.
So, to answer the question: No, the ratios are NOT proportions. I hope this helps and have a great rest of your day!
