For this case we have by definition of properties of powers that:

To multiply powers of the same base, the same base is placed and the exponents are added. Also:

$a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}$

Now, applying the above properties, we can rewrite the given expression as:

$3 ^ {-3-5} = 3 ^ {- 8} = \frac {1} {3 ^ 8}$

ANswer:

$\frac {1} {3 ^ 8}$

Answer:

The average per week flow rate of students to the gym is <u>2700</u>.

Step-by-step explanation:

Given:

Baruch college has 1000 students in the spring of 2018. 30 percent of the students use the gym twice per week, 70 percent of the students use the gym three times a week.

Now, to find the average per week flow rate of students to the gym.

Total number of students = 1000.

So, 30 percent of the students use the gym twice per week:

$30\%\ of\ 1000\times 2\\\\=\frac{30}{100}\times 1000\times 2\\\\=0.30\times 1000\times 2\\\\=600.$

Now, 70 percent of the students use the gym three times a week:

$70\%\ of\ 1000\times 3\\\\=\frac{70}{100} \times 1000\times 3\\\\=0.70\times 1000\times 3\\\\=2100.$

Now, to get the average per week flow rate of students to the gym by adding 30 percent of the students use the gym twice per week and 70 percent of the students use the gym three times a week:

$600+2100$

$=2700.$

Therefore, the average per week flow rate of students to the gym is 2700.

What perecent of 18 is 27

zalisa [80]

150% of 18 is 27

Divide 27 by 18:
$\frac{27}{18} = 1.5$

Multiply 1.5 by 100, this will convert the decimal to a percentage:
$1.5 \times 100 = 150$

Of the 100 donated gift baskets, you raffled off 97. What fraction of the baskets are left?

Nesterboy [21]

There are 100 baskets in total. 97 were raffled off. This means you'll want to subtract 97 from 100.

Let's turn those numbers into an equation:

100/100 - 97/100 = ?

100 - 97 = 3

So, ? = 3/100

3/100 cannot be simplified.
