You want to put a 5 inch thick layer of topsoil for a new 16 ft by 34 ft garden. The dirt store sells by the cubic yards. How ma

shepuryov [24]

Answer: About 8.5 cubic yards

Step-by-step explanation:

Given : The length of the garden = 16 ft.

The width of the garden = 34 ft.

The depth of the thick layer of topsoil on the garden = 5 inch

= $\dfrac{5}{12}\text{ ft.}$ [Since 1 foot = 12 inches]

The volume of a rectangular prism :-

$V=l*w*h$ , where l is length , w is width and h is height.

The number of cubic feet of topsoil required will be

$V=16\times34\times\dfrac{5}{12}=\dfrac{680}{3}\text{cubic feet}$

Since 1 yard = 3 feet

$1\text{ foot}=\dfrac{1}{3}\text{ yard}$

$V=\dfrac{680}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}=8.3950617284\approx8.50\text{cubic yards}$

Find the missing side length leave your answers as radicals in the simplest form.

ira [324]

Answer:

Part 1) $x=\frac{10\sqrt{3}}{3}\ units$

Part 2) $y=5\ units$

Step-by-step explanation:

step 1

Find the value of x

In the right triangle of the figure

$sin(30^o)=\frac{(5\sqrt{3}/3)}{x}$ ---> opposite side angle of 30 degrees divided by the hypotenuse

Remember that

$sin(30^o)=\frac{1}{2}$

substitute

$\frac{1}{2}=\frac{(5\sqrt{3}/3)}{x}$

solve for x

$x=\frac{5\sqrt{3}}{3}(2)$

$x=\frac{10\sqrt{3}}{3}\ units$

step 2

Find the value of y

In the right triangle of the figure

$cos(30^o)=\frac{y}{x}$ ---> adjacent side angle of 30 degrees divided by the hypotenuse

we have

$x=\frac{10\sqrt{3}}{3}\ units$

$cos(30^o)=\frac{\sqrt{3}}{2}$

substitute

$\frac{\sqrt{3}}{2}=\frac{y}{\frac{10\sqrt{3}}{3}}$

$y=(\frac{\sqrt{3}}{2})(\frac{10\sqrt{3}}{3})$

$y=5\ units$
