Answer:

The answer for you here is D.

Step-by-step explanation:

A. makes no sense, I don't think I need to explain myself there lol.

B. and C. both pretty much say the same thing, since you can only pick one that makes those answers sketchy. Not to mention, if anything it would be MORE biased for the survey to allow people who don't even use the service to vote.

D. This one simply makes the most sense, as that is indeed something that varies greatly from person to person. (Also I got this one right on the test :P   )

The sales tax on a $20 hammer is 7 percent, or $1.40. why is this tax a bigger burden for josh, who has a $15,000 income, than f
Bond [772]

Answer:

The ratio of the sales tax to Josh income is greater than the sales tax to aaron income (As the income of the Josh is less as compared to the arron income) this shows the tax is bigger burden for the Josh as compared to the aaron .

Step-by-step explanation:

As given

The sales tax on a $20 hammer is 7 percent, or $1.40.

As income of the  josh is 15000 and the income of the aaron is $150000 .

Now the ratio of the sales tax to the josh income .

\frac{Sales\ tax}{Josh\ income} = \frac{1.40}{15000}

\frac{Sales\ tax}{Josh\ income} = \frac{14}{15000\times 10}

\frac{Sales\ tax}{Josh\ income} = \frac{7}{75000}

In decimal form

\frac{Sales\ tax}{Josh\ income} = 0.000093\ (Approx)

Now the ratio of the  sales tax to the aaron income .

\frac{Sales\ tax}{aaron\ income} = \frac{1.40}{150000}

\frac{Sales\ tax}{aaron\ income} = \frac{14}{150000\times 10}

\frac{Sales\ tax}{aaron\ income} = \frac{7}{750000}

In decimal form

\frac{Sales\ tax}{aaron\ income} = 0.0000093\ (Approx)

Thus as the ratio of the sales tax to Josh income is greater than the sales tax to aaron income (As the income of the Josh is less as compared to the arron income) this shows the tax is bigger burden for the Josh as compared to the aaron .

Consider the inequality -20.2 > 0y. Which of the following must be true? Check all that apply. You cannot divide by zero. The
Katarina [22]

Answer:

You can not divide by zero.

The inequality is equivalent to - 20.2 > 0 which is false.

Step-by-step explanation:

We can not divide both sides by zero, because if we divide both sides by zero, then the inequality becomes

- \frac{20.2}{0} > y

⇒ - ∞ > y, which is not possible.

Again, the given inequality is - 20.2 > 0 × y.

We have to multiply y with zero and a product of zero with any term is also zero.

Hence, the inequality becomes - 20.2 > 0.

Therefore, the inequality is equivalent to - 20.2 > 0 which is false. (Answer)

alekssr [168]

Answer:

146%

Step-by-step explanation:

To find the percent increase/decrease:

1. Subtract the original value from the new value.

2. Divide by the original value.

3. Multiply the decimal by 100 to convert to a percent.

98.9 - 40.2 = 58.7

58.7/40.2 = 1.46

1.46*100 = 146%
