Answer:

\frac{3a^2b^{11}}{2}

Step-by-step explanation:

\frac{-18a^{-2}b^5}{-12a^{-4}b^{-6}}

To simplify the given expression we use exponential property

\frac{-18}{-12} =\frac{3}{2}

\frac{x^m}{x^n} =x^{m-n}

\frac{a^{-2}}{a^{-4}} =a^{-2+4}=a^2

\frac{b^{5}}{b^{-6}} =b^{5+6}=b^{11}

We substitute the simplified terms

\frac{-18a^{-2}b^5}{-12a^{-4}b^{-6}}

\frac{3a^2b^{11}}{2}

A high school has 40 players on the football team. The summary of the players' weights is given in the box plot. Approximately,
yulyashka [42]

Answer:

About 91%

Step-by-step explanation:

According to the box plot provided :

Total number of students = 40

Minimum weight = 152 pounds

Third quartile (Q3) = 245

The approximate percentage of students that weigh 245 kg or less

About 10 of the intervals out of the 11 coverage interval of the box plot fall between 152 and 254 ; Hence,

(10 / 11) * 100

90.90

= about 91 % of the total students weigh 245 kg or less

a hamster wheel has a 7 inch diameter. How many feet will a hamster travel in 100 revolutions of the wheel?
Firdavs [7]
1 revolution = circumference of the wheel = pi * diameter

= 3.14 * 7 inch

so 100 revolution = 100 * 3.14 * 7 = 2198 inches

= 2198 / 12 = 183.17 feet

Find the rate of change
eimsori [14]

Answer:

9

Step-by-step explanation:

The rate of change of a function f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

here [ a, b ] = [ 3, 7 ]

f(b) = f(7) = 47 and f(a) = f(3) = 11, hence

rate of change = \frac{47-11}{7-3} = \frac{36}{4} = 9

Mrs.Anderson writes a check for 10.50 to each of her four nieces. What will be the total change in Mrs.Andersons checking accoun
