The income tax policy for residents of a tiny island nation that uses U. S. Dollars as its currency is as follows: The first $20,000 of a citizen’s income is taxed at a rate of 10%. The next $30,000 of the citizen’s income is taxed at a rate of 18%. Any amount over $50,000 is taxed at a rate of 27%.

How much income tax would an individual with an income of x dollars be charged, where x is at least $50,000?

0.10(20,000) + 0.18(30,000) + 0.27x

0.10(x − 20,000) + 0.18(x − 30,000) + 0.27x

0.10(20,000) + 0.18(30,000) + 0.27(x − 50,000)

0.10(20,000) + 0.18(30,000) + 0.27(50,000 − x)

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

the answer is 31.27mph

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
