If enrollment increases by approximately the same
Tanya [424]

Given:

The enrollment increases by approximately the same percentage between 2000 and 2010 as it decreased between 1950 and 1960.

To find:

The expected enrollment in 2010.

Solution:

Percentage decrease formula:

\%\text{ decrease}=\dfrac{\text{Initial value - New value}}{\text{Initial value}}\times 100

The percentage decrease in between 1950 and 1960 is:

\%\text{ decrease}=\dfrac{4-3.5}{4}\times 100

\%\text{ decrease}=\dfrac{0.5}{4}\times 100

\%\text{ decrease}=\dfrac{50}{4}

\%\text{ decrease}=12.5

The enrollment decreased by 12.5% between 1950 and 1960. So, the enrollment increases by 12.5% between 2000 and 2010.

The expected enrollment in 2010 is:

\text{Expected enrollment}=7+\dfrac{12.5}{100}\times 7

\text{Expected enrollment}=7+0.875

\text{Expected enrollment}=7.875

Therefore, the expected enrollment in 2010 is 7.875 thousands.

Need help asap with math question! Thx
Solnce55 [7]

Answer: Number 1 answer: I agree with Andre. Number 2 answer: The diagram could represent 14.

Step-by-step explanation:

1. I agree with Andre because the squares are all tenths. so the first rectangle has 10 tenths which is 100. The four small squares equal 40 since 4 tenths is 40. If you add them both you get 140.

2. The diagram could represent 14 because you can think of the squares as ones. so ten ones is 10, and four ones is 4. So 10 plus 4 is 14.
