Answer:
142.5, rounded to 143 women.
Step-by-step explanation:
A squadron with 750 members is the common multiple of the sum of 19 and 81.
Therefore, the number of women in a squadron is equal to [750 : (19 + 81)] x 19 = 142.5.
9/r= 3/10
Cross multiply:
3*r= 9*10
⇒ r= 9*10/3
⇒ r= 30
The final answer is 30~
1/5 is .2
.1^2 is .01
.02 is .02
So the furthest left would be the smallest number, which in this case is 0.1^2
Step-by-step explanation:
4(5x-2) = 2(9x+3)
20x-8 = 18x+6
20x-18x = 6+8
2x=14
x= 14/2
∴ x= 7 [ANS]
Answer:
Difference in area of the last square and the initial square = 440 cm²
Step-by-step explanation:
Length of the side of a square = 1 cm
Area of the square = (side)² = 1 cm²
Addition of side length every minute = 2 cm
After x minutes length of each side of the square = (1 + 2x) cm
If x = 10 minutes
Length of each side of the square = [1 + 2(10)]
= 21 cm
Area of the square after 10 minutes = (21)²
= 441 cm²
Therefore, difference in area of the last square and area of the initial square
= 441 - 1
= 440 cm²
