Help me out I can’t figure out how to do this

Check the picture below.

\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=\frac{1}{4} \end{cases}\implies V=\cfrac{4\pi \left( \frac{1}{4} \right)^3}{3}\implies V=\cfrac{4\pi\frac{1}{64}}{3} \\\\\\ V=\cfrac{\frac{4\pi}{64}}{3}\implies V=\cfrac{\frac{\pi}{16}}{\frac{3}{1}}\implies V=\cfrac{\pi }{16}\cdot \cfrac{1}{3}\implies V=\cfrac{\pi }{48}\implies \stackrel{\textit{rounded up}}{V=0.07}

Triangle ABC is a right triangle and cos(22.6)=b/13. Slobs for b and round to the nearest whole number
aliina [53]
<u>Answer</u>
12


<u>Explanation</u>
Cosine is the ratio of adjacent to hypotenuse.

So, in this case b is the adjacent and 13 is the hypotenuse.

cos22.6 = b/13
b = 13×cos22.6
    = 13×0.923879532
    =12.010

To the nearest whole number the answer is 12.

A radio station ordered hats and coffee mugs to give away as prizes. A total of 1,000 of these items were ordered, and 3 times a
marshall27 [118]

Answer:

The options are not shown, so i will answer in a general way.

Let's define the variables:

h = number of hats

m = number of mugs.

We know that a total of 1000 items were ordered, then:

h + m = 1000

We also know that we have 3 times more mugs than hats, this can be written as:

m = 3*h

Now we have the system of equations:

h + m = 1000

m = 3*h

To solve these, we usually start by isolating one of the variables in one equation and then replace that in the other equation, but in this case, we already have m isolated in the second equation, then we can replace that in the first equation to get:

h + m = 1000

h + (3*h) = 1000

Now we can solve this equation for h, and find the number of hats ordered.

4*h = 1000

h = 1000/4 = 250

There were 250 hats ordered.
