Answer:

The answer is A

Step-by-step explanation:

Step 1: Use Cosine to find ∅

Perform the following division:

Hey!

Alright, the first step to solving this division problem would be to convert the mixed fraction into a simple fraction. To do that, we'll multiply the denominator by the whole number and then add that total to the numerator.

<em>Original Fraction :</em>
$3 \frac{3}{4}$

<em>New Fraction {Changed by Conversion} :</em>
$\frac{15}{4}$

Now that we've successfully done that we'll have to change the equation.

<em>Old Equation :</em>
$\frac{15}{4}$ ÷ $\frac{2}{8}$ = ?

<em>New Equation {Changed by Flipping the Second Fraction and the Symbol} :</em>
$\frac{15}{4}$ · $\frac{8}{2}$ = ?

Now we multiply straight across.

<em>Old Equation :</em>
$\frac{15}{4}$ · $\frac{8}{2}$ = ?

<em>Solved :</em>
$\frac{120}{8}$

Almost done!
Now we have to simplify the fraction.

<em>Old Fraction :</em>
$\frac{120}{8}$

<em>New Fraction {Changed by Simplification} :</em>
$\frac{15}{1}$

Now just convert it to a whole number by removing the fraction line and the number, and that's it!

<span><em>So, $3 \frac{3}{4}$ ÷ $\frac{2}{8}$ equals</em></span> 15.

Hope this helps!

Find the missing length

jasenka [17]

Answer: 15

Step-by-step explanation:

For this you will have to use pythagoras’ theorem.

The formula for the shorter side of this triangle is u²=c²-b² (or in this case u²=17²-8²).

17²=289

8²=64

The formula becomes u²=289-64 or u²=225

Then to find u on its own you have to square root 225.

The square root of 225 is 15.

He could be 40321 years old.
If you divide 40321 by any odd or even number between 1 and 9, the remainder is 1.

I got this number by doing (2*3*4*5*6*7*8) + 1
