A computer that originally cost $500 is on sale for $350. What is the percent discount?

laiz [17]

Answer:

30%

Step-by-step explanation:

500 - 350 = 150
Set up a proportion: $\frac{150}{500} = \frac{x}{100}$
Cross multiply, then divide: 150 × 100 = 15000, 15000 ÷ 500 = 30
Write the completed fraction: $\frac{30}{100}$
$\frac{30}{100} =$ 30%

I hope this helps!

Find the indicated side length by using Sin, Cos, and Tan.

Elena L [17]

So we are looking for side $z$ and we are given the length of hypotenuse ( $b=18$ ) and angle $\zeta=60$ .

The function I would use is sine.

$\sin(\zeta)=\frac{z}{b}$

If we solve for side $z$ :

$z=b\times\sin(\zeta)$

Now fill in the data.

$z=18\times\sin(60)\approx\boxed{15.59}$

$\bf \cfrac{\textit{similar shape}}{\textit{similar shape}}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\\\\
-------------------------------\\\\
\cfrac{smaller}{larger}\qquad \cfrac{3}{4}=\cfrac{\sqrt{13}}{\sqrt{a}}\implies \cfrac{3}{4}=\sqrt{\cfrac{13}{a}}\implies \left( \cfrac{3}{4} \right)^2=\cfrac{13}{a}
\\\\\\
\cfrac{3^2}{4^2}=\cfrac{13}{a}\implies \cfrac{9}{16}=\cfrac{13}{a}\implies a=\cfrac{16\cdot 3}{9}$
