The two square roots of 4,900 are +70 and -70 . 70 x 70 = 4,900 (-70) x (-70) = 4,900
810000
3.5/5 X 100 => 3.5 X 20 => 70%
five tenths of 70 = 70 x 5/10 which is the same as 70 x 1/2 Then you turn the times to a divide and divide it by the reciprocal of 1/2 which makes 70 / 2 which is 35!
-5 x 14 = -70
Percentage decrease from 70 to 30 is ((70 - 30)/70) x 100 = (40/70) x 100 = 4000/70 = 400/7 = 57.14%
x - 30% of x = 91 → 70% x = 91 → x = 91÷ 70% = 130
21/30 x 100 = 70. Therefore, 21 is 70 percent of 30.
(30/100) X 70 feet = 21 feet.
Yes: 300 x 7 = 2,100 30 x 70 = 2,100
the answer is 42.9 % 30 X 100 = 3000 3000 : 70 = 42.85714286
70 x 30 = 2100 7 x 30 = 210
70' x 30' = 70*30 square feet = 2100 sq feet.
To find the percent that a number, x, is out of another number, y, divide x by y and multiply by 100. So (21/30)*100 = 70, which means that 21 is 70% of 30.
21/30 x 100% = 70%
30 % off of 525 is (100 - 30 = 70) % of 525 remaining: 70 % of 525 = 70/100 x 525 = 367.5
2 x 3 x 5 = 30 2 x 5 x 7 = 70 2 x 3 x 5 x 7 = 210, the LCM
