1. if a = 16 and b= 12, find c

klasskru [66]

Answer:

20

Step-by-step explanation:

The pythagorean theorem states that

$a^2+b^2=c^2$

So $16^2 + 12^2 = c^2\\256+144 = c^2\\400 = c^2$

You would then do

$400 = c^2\\\sqrt{400} = c$

Because a square root is the opposite of a square.

$\sqrt{400} = 20$

because 20 * 20 = 400

A clothing store pays $89.47 for a dress. The store’s percent of markup is 50% and the tax is 7.6%. Find the selling price for t

Goryan [66]

Hi,
<span>SP=Selling Price
</span>CP of dress= $ 89.47
percent of mark up = 50%
SP without tax= 100+ mark up % /100 * CP
<span>SP without tax= 100+50/100 * 89.47
</span>SP without tax= 150/100 * 89.47
SP without tax= 1.5 * 89.47
<span>SP without tax= $ 134.205
</span>tot. SP(SP with tax)= 100 + tax %/100 * SP
<span>SP=100 + 7.6/100 * 134.205
</span>SP= 107.6/100 * 134.205
SP= 1.076 * 134.205
<span>SP= $144.40458
Hope this helps you.</span>
