Answer:
If there are 10 students taking only chemistry, 9 students taking only physics, and 5 students only taking both chemisty and 16 students are taking neither; I would add 10+9+5+16=40 (total students) and divide 10/40 (25% chemistry) 9/40 (22.5% physics) 5/40 (12.5% both) 16/40 (40% neither)
Step-by-step explanation:
1. Determine a single event with a single outcome.
2. Identify the total number of outcomes that can occur.
3. Divide the number of events by the number of possible outcomes.
Answer:
D. Nine months
Step-by-step explanation:
Simple interest=principal×rate×time
Principal=$1800
Rate=4.5%
Time=?
Interest=$60.75
Simple interest=principal×rate×time
60.75=1800×4.5×t/100
60.75=8100t/100
60.75=81t
t=60.75/81
t=0.75 year
0.75 years=9 months
Answer: 51
Step-by-step explanation:
From the question, we are informed that there are 2601 students in a school and that the teacher want them to stand in rows and columns.
Since the number of the row and column are equal, thus will go thus:
Let the number of row and column be represented by y. Therefore,
y × y = 2601
y² = 2601
y = ✓2601
y = 51
Therefore the rows and columns must be 51 each.

x = -9
x = 2
Step-by-step explanation:
Given:
First, note that
Since and stay in the denominator, then
Now add two fractions which stay in the left part. The common denominator is so multiply the numerator of the first fraction by and the numerator of the second fraction by and subtract them in the numerator:
