Aloiza [94]

Answer:

$- 32$

Step-by-step explanation:

1) Simplify

$\sqrt{32} \: to \: 4 \sqrt{2}$

$- 8 \sqrt{2} \times \frac{1}{2} \times 4 \sqrt{2}$

2) Use this formula: a/b × c/d = ac/bd.

$- \frac{8 \sqrt{2} \times 1 \times 4 \sqrt{2} }{2}$

3) Simplify.

$- \frac{32 \sqrt{2 \sqrt{2} } }{2}$

$simplify \: 32 \sqrt{2 } \sqrt{2} \: to \: 32 \sqrt{4}$

5) Since 2 × 2 = 4, the square root of 4 is 2.

$- \frac{32 \times 2}{2}$

6) Simplify 32 × 2 to 64.

$- \frac{64}{2}$

7) Simplify 64/2 to 32.

$- 32$

Therefor, the answer is option three -32

Fernanda has a collection of 200 seashells from corpus christi she gage her sister one-fifth of her collection how many seashell

Katarina [22]

Answer: 160

Step-by-step explanation: She gave her sister one fifth of the collection; one fifth written as a percent is 20% (I did one and divided it by five). To turn 20% to a decimal I didved by 100 to get 0.20. I multiplied 200 and 0.20 and got 40. 40 is the amount of shells given to her sister, so you would subtract 40 from 200 to find how many shells were left. 200-40=160.

The sales tax on a 15,000 car is 540. at this rate what is the tax on a 32,000 car

maria [59]

Note : Since unit of currency is not defined, I'll be using units.

Sales tax on a 15000 units car = 540 units
540 = 15000 × tax% / 100
=> 540 = 15000 × tax% / 100
=> 540/15000 = tax% / 100
=> tax% = (540/15000) × 100
=> tax% = 540/140
=> tax% = 3.6

now,
sales tax on a 32000 units car = 32000 × tax%/100
= 32000 × 3.6/100
= 320 × 3.6
= 1152 units
therefore sales tax on a 32000 units car = 1152 units
