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
