Answer:
i). 211.
ii). 711.
iii). 31
iv). 131.
Step-by-step explanation:
i). √37460 = 193.545
Then take the whole number from the decimal:
193² = 193 × 193 = 37249
You subtract the answer from the main number:
37460 - 37249 = 211
211 is the answer.
ii). √506900 = 711.969
711² = 711 × 711 = 505521
506900 - 505521 = 1379
1379 is the answer.
iii). √4931 = 70.221
70² = 70 × 70 = 4900
4931 - 4900 = 31
31 is the answer.
iv). √5607 = 74.879
74² = 74 × 74 = 5476
5607 - 5476 = 131
131 is the answer.

C.) 68
Why?
a triangle has 180 degrees.
The tics denote the sides being equal, which means the opposite angles are equal, too. To get the remaining subtract it from 180... 180- 2(56) =68 degrees
The first one includes both
Answer: 17 years
Step-by-step explanation:
Let mary's age be m
2m-7 = m+10
Subtracting m from both sides:
m-7 = 10
Therefore, m = 17
