Answer: 150 boys
Step-by-step explanation:
Let the number of boys be x
Since there were 200 more girls than boys, the number of girls will be: = x + 200
Since the ratio of boys to girls was 3:7, this can be solved further below:
3/7 = x/x+200
Cross multiply
(7 × x) = 3(x + 200)
7x = 3x + 600
7x - 3x = 600
4x = 600
x = 600/4
x = 150
The number of boys enrolled is 150
Number of Girls will be:
= X + 200
= 150 + 200
= 350
Check: Number of boys / Number of girls
= 150/350
= 3/7
= 3:7
Answer:
x = 11.2
Step-by-step explanation:
hypotenuse = 8.4 (radius) + 5.6 = 14
using the Pythagorean theorem:
x² = 14² - 8.4² = 196 - 70.56 =125.44
x = √125.44 = 11.2
Answer:
~15 meters away
Step-by-step explanation:
c^2 = a^2+b^2
c^2 = 10^2+11^2
c^2 = 100+121
c^2 = 221
c = 
c = ~15

Further explanation</h3>
<u>Given:</u>

- A fraction represents part of a whole.
- A fraction consists of a numerator and a denominator. i.e.,
. - The numerator = the number of equal parts of a whole.
- The denominator = the total number of parts that make up said whole.
From the problems above, the denominator or the bottom numbers are still different. We use the Least Common Multiple (or LCM) to equalize the denominator.
- Multiples of 3:

- Multiples of 4:

- Multiples of 6:

Hence, the LCM for 3, 4, and 6 is 12.
We change the denominator for each fraction to 12.



Then we continue adding fractions.


Thus, the result is
