A bedroom measures 15 ft by 14 ft with a closet that measures 4 ft by 8 ft. if carpet costs $4.25 per foot, how much will it cost to carpet the room and closet..

Answers

Answer 1
Answer: First of all, I must assume that the correct cost for carpet is $4.25 per square foot.
It could be $4.25 per foot if it came of a standard roll, but then I would need to know the width of the roll, which you haven't given.

Area of the room = (15-ft x 14-ft) = 210 square feet

Area of the closet = (4-ft x 8-ft) = 32 square feet

Total area = (210 + 32) = 242 square feet.

Total cost of carpet = (242 x $4.25) = $1,028.50 plus pad and installation.
=========================================
You know what ?  I think you may have mis-copied the price of carpet altogether.
At $4.25 per square foot, that's awfully expensive carpet.
I suspect the actual price is $4.25 per square yard.  That's pretty cheap, but 
it's a lot closer to reasonable than $4.25 per square foot is ($38.25 per yd² !) 

If it's $4.25 per square yard, then we need to know that 1 square yd = 9 square ft.

The total requirement is 242/9 = 26 and 8/9 square yard, so you'll buy 27 sq yds.

$4.25 x 27 = $114.75 plus pad and installation.  That sounds cheap but better.

\hbox {Let x - to be your number.}

2x+7=93 ⇒ 2x=93-7 ⇒ 2x=86

x= (86)/(2) ⇒ \boxed {x=43}
Subtract 7 from both sides
2 . x = 86 Divide both sides by 2
X = 43

Subtraction of polynomials are done just as normal subtraction, but you can only subtract those with the same variables and exponents. This is shown below:

Which of these conditions might be true if polygons ABCD and KLMN are similar? A. The measures of corresponding angles of ABCD and KLMN are equal, but the lengths of corresponding sides of ABCD are half those of KLMN.B. The measures of corresponding angles of ABCD and KLMN are in the ratio 1 : 2, but the lengths of corresponding sides of ABCD and KLMN are not proportional.
C. The lengths of corresponding sides of ABCD and KLMN are equal, but the measures of corresponding angles of ABCD and KLMN are not equal.
D. The lengths of corresponding sides of ABCD and KLMN are proportional, but the measures of corresponding angles of ABCD and KLMN are not equal.
E.The measures of corresponding angles of ABCD and KLMN are not proportional, but the lengths of corresponding sides of ABCD and KLMN are proportional.

Answers

The correct answer is:


A) The measures of corresponding angles of ABCD and KLMN are equal, but the lengths of corresponding sides of ABCD are half those of KLMN.


Explanation:


The definition of similar polygons is two polygons whose corresponding angles are congruent and whose corresponding sides are proportional.


If the lengths of the corresponding sides of ABCD are half of those of KLMN, this is the proportion 1:2.


Combined with the fact that the measures of the corresponding angles are congruent, this makes ABCD and KLMN similar polygons.

The question ask to choose among the following choices that state the truth about the condition if polygon ABCD and KLMN are similar and the answer would be letter  A. The measures of corresponding angles of ABCD and KLMN are equal, but the lengths of corresponding sides of ABCD are half those of KLMN.

Michael works at a furniture store. He makes a commission for every piece of furniture he sells. He sold a couch for $1245 and received a check for $62.25. What was the % of commission he made? A. 5% B. 6% C. 7% D. 8%

Answers

Answer: A, 5%

Step-by-step explanation: First set up an equation to solve this: (62.25)/(1245) =(x)/(100)
Next, you cross-multiply, simplifying the equation to: 1245x=6225

Now you isolate the x by dividing both sides by 1245 giving you: x=5

Hope this helped
