Answer:
4 : 7
Step-by-step explanation:
The area ratio is the square of the side length ratio. So, the side length ratio is the square root of the area ratio.
side length ratio = √16 : √49 = 4 : 7
The answer is 125. 40x2 is 80, 50x2 is 100, 20 percent left, 20 is half of 40, half of 50 is 25, 100+25=125.
Answer:
144,148,152
Step-by-step explanation:
Here we will have, 4x + 4(x+1) + 4(x+2) = 444
=> x + (x+1) + (x+2) = 111 (dividing both sides by 4)
=>x + x+1 + x+2 =111
=> 3x + 3 = 111
=> 3x = 108
=> x = 36.
So, the three desired numbers 4x, 4(x+1) and 4(x+2) are,
4*36, 4*(36+1) and 4*(36+2)
That means the numbers are, 144, 148 and 152.
