X=4

You have to distribute the negative sign for everything in the parentheses. After that you add x to the other side then add 8 to the opposite side to move them. Then your answer is 4.

Find the volume of the garden shed

Leno4ka [110]

Answer:

47.3 m³

Step-by-step explanation:

The garden shed is made up of a rectangular prism and a pyramid.

<h3><u>Volume of a rectangular prism</u></h3>

$\begin{aligned}\textsf{Volume of a rectangular prism}&=\sf width \times length \times height\\&=4 \times 4 \times 2\\&=16 \times 2\\&=32\;\; \sf m^3\end{aligned}$

<h3><u>Volume of a pyramid</u></h3>

<u />

From inspection of the given diagram, the slant height of the pyramid is 3.5 m.

Calculate the perpendicular height of the pyramid using Pythagoras Theorem:

$\begin{aligned}\implies a^2+b^2&=c^2\\2^2+h^2&=3.5^2\\h^2&=8.25\\h&=\sqrt{8.25}\;\; \sf m\end{aligned}$

Therefore:

$\begin{aligned}\textsf{Volume of a pyramid}&=\dfrac{\sf length \times width \times height}{3}\\\\&=\dfrac{\sf 4 \times 4 \times \sqrt{8.25}}{3}\\\\& = 15.31883372\;\; \sf m^3\end{aligned}$

<h3><u>Volume of the garden shed</u></h3>

$\begin{aligned}\implies \textsf{Volume of shed}&=\textsf{Volume of rectangular prism}+\textsf{Volume of pyramid}\\&=32+15.31883372\\& = 47.3\;\; \sf m^3\;(nearest\;tenth)\end{aligned}$

Assume that when you take a bath, you fill a tub to the halfway point. The tub measures 6 feet by 3 feet by 2.6 feet.

masya89 [10]

Using the volumes, it is found that you spend more water taking a bath.

<h3>What is the volume of a rectangular prism?</h3>

The volume of a rectangular prism of length l, width w and height h is given by:

V = lwh.

For this problem, the dimensions of the tub are as follows:

l = 6, w = 3, h = 2.6.

You use half of that, hence:

V = 0.5 x 6 x 3 x 2.6 = 23.4 feet³.

For the bath, the number of cubic feet is:

1.42 x 11/7.5 = 2.08 feet³.

Hence you spend more water taking a bath, as 23.4 > 2.08.

Crunchee Corporation increases the size of its granola packages from 16 ounces to 20 ounces. What is the percent of crunchees gr

garik1379 [7]

The percentage would be 4% because you have to subtract 20 from 16 to find the percentage and that would be 4. :D

Hope this helped. :D<span />
