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 .

Is 3.142857 a rational number

gregori [183]

If you're talking about just the decimal, then yes it is.
If you're talking about 22/7, then it still is.
But if you're talking about pi, then it isn't rational.

select the values that make the inequality h/4 greater than or equal to -1 true then write an equivalent inequality in terms of

jok3333 [9.3K]

Answer:

Values that make it equal:

-4, -3, -1, 0, 4

Written equivalent inequality:

h≥−4

Step by Step for the written inequality:

h/4 ≥−1

Multiply both sides by 4. Since 4 is positive, the inequality direction remains the same.

h≥−4

I hope this helps you!! :)

If in triangle ABC, a=5, b=6 and c=8, then cos A is...

s2008m [1.1K]

In a triangle, the nomenclature is that a variable side a is opposite of the angle A. we can use the cosine law to determine the value of cosine A.
a2 = b2 + c2 -2bc cos a25 = 36 + 64 - 2*6*8 * cos acos a = 25/32
