Answer:

$225.50 (nearest cent)

Step-by-step explanation:

1 foot ≈ 0.3048 m

Width of room = 15 ft ≈ 15 x 0.3048 = 4.572 m

Length of room = 18 ft ≈ 18 x 0.3048 = 5.4864 m

Area of room = width x length = 4.572 x 5.4864 = 25.0938208... m²

Cost of carpet = $8.99 per m²

Total cost of carpet = 25.0938208 x 8.99 = $225.50 (nearest cent)

A car dealership pays you 4% commission on your first $8,000 in car sales and 8% commission on additional sales over the $8,000.
Zigmanuir [339]

Answer:

Total Commission = $400


Step-by-step explanation:

Since total is $9000 (in sales) -- commision is 4% on the first $8000 and 8% in the additional part over $8000 (9000-8000=1000). So 8% on $1000.


<u>Total commission</u> = 4% of 8000 + 8% of 1000

= (0.04)(8000) + (0.08)(1000)

= 400


Total Commission is $400

terry opened a savings account in December with $132 and saved $27 each month beginning in January the value of terrys account i
liq [111]
Let S be the amount in a savings account. 
Let m be the number of months.

General equation
S = 132 + 27m

Specific question
July is the 7th month of the year including both January and July.
S = 132 + 7*27
S = 132 + 189
S = 321

Reasonableness?
Good question. You could estimate an answer.
Start with 150 dollars and say that you add 25 a month.
7 * 25 = 175
S = 150 + 175 = 325 All of this was done in my head. Since the exact answer obtained using the formula is 321, I think that's pretty reasonable using my estimate is a guide.

Answer:

d.every word in the first sentence of the first page of every chapter.

Step-by-step explanation

  • the sample space means the set of total possible outcomes or ALL possible outcomes.

  • the favorable outcome is the set which has all the words that the students would not know from all the words read  by the teacher or simply from the sample space.
  • since the teacher reads  the first sentence on the first page in every chapter , all the words in that sentence will be sample in this situation.
