Answer:
Step-by-step explanation:
Use the Pythagorean Theorem: a^2 + b^2 = c^2 where a and b are the sides and c is the hypotenuse
21^2 + 28^2 = c^2
441 + 784 = c^2
1125 = c^2
Now you need to take the square root of 1125 to find the value of x, which would be approx 33.5
Set up a proportion.
Let x = the number of students in 29970 who speak 3 or more languages.
285/19 = 29970/x Cross multiply
285 x = 19 * 29970
285x = 569430
x = 569430/285
x = 5415 students speak 3 languages.

Answer:
50 dollars per month
Step-by-step explanation:
Given
Required
Determine the rate of savings
Suppose in a month, she saves x amount.
In 2 months, she would save 2x
When 2x is added to the initial savings, it gives the total amount saved.
So, we have:
Collect Like Terms
Divide both sides by 2
<em>Hence, she saves $50 dollars monthly</em>
