Answer: 56/299

Step-by-step explanation:

Find the LCD (least common denominator) of the two numerators, which is 299. Then make the denominators in same as the LCD. Multiply the top part of each fraction individually, then subtract them together. Then join the two denominators together and simplify.

Hope this helps, have a blessed and wonderful day, as well as a good rest of your 2020 school year!

How many band uniforms can be made with 131 3/4 yards of fabric if each uniform requires 3 7/8 yards

ElenaW [278]

The question can be read as how many $3 \frac{7}{8}$ can be made out of $131 \frac{3}{4}$

$131 \frac{3}{4}$ ÷ $3 \frac{7}{8}$ ⇒ We need to change each mixed number into an improper fraction

$131 \frac{3}{4}= \frac{[131*4]+3}{4}= \frac{527}{4}$
$3 \frac{7}{8}= \frac{[3*8]+7}{8} = \frac{31}{8}$

$\frac{527}{4}$ ÷ $\frac{31}{8}$
$\frac{527}{4}$ × $\frac{8}{31}$
$\frac{527*8}{4*31}= \frac{4216}{248} =17$

Find the exact value of the expression. Do not use a calculator. If tan θ = 9, find the exact value of cot θ

adelina 88 [10]

$\bf tan(\theta )=9\implies tan(\theta )=\cfrac{\stackrel{opposite}{9}}{\stackrel{adjacent}{1}}\impliedby \textit{let's find the \underline{hypotenuse}} \\\\\\ \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c=\sqrt{a^2+b^2} \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases}$

$\bf c=\sqrt{1^2+9^2}\implies c=\sqrt{82} \\\\[-0.35em] ~\dotfill\\\\ cos(\theta )=\cfrac{\stackrel{adjacent}{1}}{\stackrel{hypotenuse}{\sqrt{82}}}\implies \stackrel{\textit{rationalizing the denominator}}{cos(\theta )=\cfrac{1}{\sqrt{82}}\cdot \cfrac{\sqrt{82}}{\sqrt{82}}}\implies cos(\theta )=\cfrac{\sqrt{82}}{82}$
