The 7th graders at Sunview Middle School were helping to renovate a playground for the kindergartners at a nearby elementary sch

ool. City regulations require that the sand underneath the swings be at least 15 inches deep. The sand under both swing sets was only 12 inches deep when they started.
The rectangular area under the small swing set measures 9 feet by 12 feet and required 40 bags of sand to increase the depth by 3 inches. How many bags of sand will the students need to cover the rectangular area under the large swing set if it is 1.5 times as long and 1.5 times as wide as the area under the small swing set?

What is the inverse equation for h(x) = 2log(x-3) ?
marshall27 [118]

Given the function:

h(x)=2log\left(x-3\right)

To find its inverse:

\begin{gathered} y=2log\left(x-3\right) \\ x=2log\left(y-3\right) \end{gathered}

solving for y:

\frac{x}{2}=log(y-3)\begin{gathered} 10^{\frac{x}{2}}=y-3 \\  \\ 10^{\frac{x}{2}}+3=y \end{gathered}

ANSWER

h^^{-1}(x)=10^{\frac{x}{2}}+3

Determine the answer to 3 + -5 and explain the steps using a number line
Marizza181 [45]
Adding a positive to a negative, you would look at the number with the greater absolute value, and that number would determine the sign of the sum. 

5 - 3 = 2

Since 5 is bigger, you use that sign

-5 

-2

Answer: -2

A laptop has a listed price of $843.88 before tax if the sales tax rate is 7.25% find the total cost of the laptop with sales ta
Step2247 [10]

Answer:

$905.06 dollars

Step-by-step explanation:

Given the following question:

7.25% of 843.88

In order to find the answer, we use the formula to calculate percentages, then we add that answer to the initial cost of the laptop.

\frac{p\times c}{100}
\frac{7.25\times843.88}{100}=7.25\times843.88=6118.13\div100=61.1813
61.1813
1 < 5
61.18

<u>Now add:
</u>843.88+61.18=905.06
=905.06

Which means the laptop after a 7.25% sales tax costs "$905.06 dollars."

Hope this helps.
