B: 83
explanation:
62+35=97
180-97=83
32 meters tall.
It would form a right triangle, in which the shorter leg is 7m and the longer leg is 24m. You're looking for the last side, the hypotenuse. So use the Pythagorean theorem. a^2 + b^2 = c^2 , in which a and b are the legs and c is the hypotenuse.
Therefore, you get 7^2 + 24^2 = c^2.
Which is, 49 + 576 = c^2
Add, 625 = c^2.
Take the square root of 625, which is 25. So, the length of the hypotenuse (last side) is 25m. Add the 7m that is sticking out of the ground, to get 32m.

Answer: 12 years
Step-by-step explanation:
Let x be Timothy's present age .
The, Adele's present age = x+5
After 3 years, Timothy's age = x+3
Adele's age =x+5+3=x+8
According to the question, we have
Hence, the current age of Timothy = 7 years
The current age of Adele =7+5=12 years.
Answer:
42
Step-by-step explanation:
Total = 140 Jelly Beans
You are interested in the 3 part of the ratio.
Notice the word total. You should not be using 3/7 at all.
The ratio you want is 3/10. 10 represents the total.
3/10 = x / 140 Cross multiply
10 x = 3 * 140
10x = 420 Divide by 10
10x/10 = 420 / 10
x = 42
Check
How many jelly beans are left?
140 - 42 = 98
Thats the number of Blue Jelly Beans.
Does 42/98 = 3/7?
Yes. Divide top and bottom by 14 and you get 3/7
