Answer:
18
Step-by-step explanation:
70^2 = 4900 < 5607 < 6400 = 80^2
so sqrt(5607) is a two-digit number with tenth-digit 7
71^2 = 5041, 72^2 = 5184, 73^2 = 5329, 74^2 = 5476, 75^2 = 5625
so the smallest square bigger than 5607 is 75^2, which is 5625
so the number should ne 5625 - 5607 = 18
Answer:
One solution: 0x + 0.5y = 0
Step-by-step explanation:
9x + 4y = 36
6x + 2.5y = 24
2 * Eq. 1
18x + 8y = 72
-3 * Eq. 2
-18x - 7.5y = -72
Add the multiples of the equations.
0x + 0.5y = 0
Answer: One solution: 0x + 0.5y = 0
460 (envelopes) / 30 (minutes) = 15.3 rounds down to 15 envelopes per minute
The answer would be cos(52°)
Length = l = 3 m ,
Breadth = b = 4 m
Length of the Longest rod placed in
the room = length of the diagonal of the floor
= √ l² + b²
= √ 3² + 4²
= √ 9 + 16
= √ 25
= 5
I hope this helps you.
