There were 600 students at the north campus and 400 students at the south campus.
<h2 /><h3><u>Calculus</u></h3>
To determine, if 42% of the 1000 students at the east campus are music majors, how many students did the north and south campuses have before the merger, the following calculation must be performed:
- 0.10X + 0.90Y = 420
- 1000 x 0.42 = 420
- 500 x 0.10 + 500 x 0.90 = 50 + 450 = 500
- 600 x 0.10 + 400 x 0.90 = 60 + 360 = 420
Therefore, there were 600 students at the north campus and 400 students at the south campus.

Answer:
x-0.33x = 0.67x
Step-by-step explanation:
Given : A new soup recipe contains 33% less sodium per serving than the old soup recipe.
The old soup recipe contained x milligrams of sodium per serving.
To Find: Which of the following expressions could represent the amount of sodium per serving, in milligrams, in the new soup recipe
Solution :
Since we are given that old recipe contains x milligrams of sodium per serving
And new recipe contains 33% less sodium per serving than the old soup recipe.
So, 33%of x = 0.33x
Since new recipe contains 33% less sodium than old recipe:
⇒x-0.33x
or
⇒(1-0.33)x
⇒0.67x
Thus expressions which could represent the amount of sodium per serving, in milligrams, in the new soup recipe :
x-0.33x or 0.67x
The answer is 2 drinks left
This corresponds to a sinusoidal graph, we have:
Radius= 20 feet, that corresponds to the amplitud (A)
One revolution takes 24 seconds, that corresponds to the period
Min= 3 feet
k=360/24=15
D= bottom distance+ amplitud=3+20=23 feet
Then, let x be the time, in seconds:
a) To determine Reid's height after 1 minute= 60 seconds, substitute x=60
b) To determine when Reid's height will first reach 18 feet, we have to substitute y=18 feet, and isolate x:
