A study found that a factory produces 6 defective computers for every 500 computers that are produced. On the average, what perc

masya89 [10]

Answer:

1.2%

Step-by-step explanation:

We know that for every 500 computers, 6 are defective. So, to know what percentage of computers are defective on average, we can do a rule of three:

500 computers -> 6 defective

100 computers -> X defective

500/100 = 6/X

X = 100 * 6 / 500 = 1.2

So, in average, for every 100 computers, 1.2 are defective, so the percentage is 1.2% (1.2 for every 100)

What is the solution to the equation One-third (x minus 2) = one-fifth (x + 4) + 2? x = 12 x = 14 x = 16 x = 26

Elena L [17]

Answer:

x = 26

Step-by-step explanation:

Given

$\frac{1}{3}$ (x - 2) = $\frac{1}{5}$ (x + 4) + 2

Multiply through by 15 to clear the fractions

5(x - 2) =3(x + 4) + 30 ← distribute and simplify both sides

5x - 10 = 3x + 12 + 30, that is

5x - 10 = 3x + 42 ( subtract 3x from both sides )

2x - 10 = 42 ( add 10 to both sides )

2x = 52 ( divide both sides by 2 )

x = 26

Divide x to the 1 half power divided by x to the 2 sevenths power.

juin [17]

$\frac{x^\frac{1}{2} }{x^\frac{2}{7}}$

According to the rule of exponents $\frac{a^m}{a^n} = a^{(m-n)}$ , i.e. when two terms are in division with same base , we subtract the exponents

$\frac{x^\frac{1}{2} }{x^\frac{2}{7}} = x^{(\frac{1}{2}) - (\frac{2}{7})}$

$=x^\frac{3}{14}$

x to the 3 fourteenths power

Boof<br>$543.51 is subtotal.

antiseptic1488 [7]

Answer:

The total of the sales price and sales tax is $ 588.35 .

Step-by-step explanation:

As given

$543.51 be the subtotal .

8.25% is the sales tax .

8.25% is written in the decimal form.

$= \frac{8.25}{100}$

= 0.0825

Sales tax price = 0.0825 × 543.51

= $ 44.84 (Approx)

Total of sales price with sales tax = Sale price + Sales tax price

Putting the values in the above

= $543.51 + $44.84

= $ 588.35

Therefore the total of the sales price and sales tax is $ 588.35 .
