You need to buy a carpet that measures 7.5 yards long and 5 yards wide and costs $49.50 per square yard. How much will the carpet for the room cost?
Answer:
$1,856.25
Explanation:
To find the square yards, multiply length and width
7.5 * 5 = 37.5
Then, since each square yard costs $49.50, multiply the square yards and the cost
37.5 * 49.50 = 1,856.25
Thus the answer is $1,856.25
The carpet for the room will cost $1,856.25.
This is the product of the unit cost per square yard multiplied by the area of the room.
The area of the room is = 37.5 square yards (Length x Width)
Length of the room = 7.5 yards
Width of the room = 5 yards
Therefore, the total area of the room = 37.5 square yards (7.5 x 5)
Thus, the total area of the room is 37.5 square yards and since each square yard costs $49.50, the total cost for buying the carpet will cost $1,856.25 ($49.50 x 37.5).

Residents of the town of Maple Grove who are connected to the municipal water supply are billed a fixed amount monthly plus a charge for each cubic foot of water used. A household using 1900 cubic feet was billed $156, while one using 2600 cubic feet was billed $184. (a) What is the charge per cubic foot? dollars per cubic foot (b) Write an equation for the total cost, c, of a resident's water, , as a function of cubic feet of water used. c(w) = dollars c) How many cubic feet of water used would lead to a bill of $216? cubic feet
9514 1404 393
Answer:
$0.04 per cubic footc(w) = 0.04w +803400 cubic feetStep-by-step explanation:
(a, b) We are given two pairs of values:
(w, c) = (1900, 156) and (2600, 184)
so we can write the equation of the relationship using the 2-point form of the equation of a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
c = (184 -156)/(2600 -1900)(w -1900) +156 . . . . . substitute given points
c = 28/700(w -1900) +156
c(w) = 0.04w +80
The charge per cubic foot is $0.04.
__
(c) For a bill of $216, the amount of water used is ...
216 = 0.04w +80
136 = 0.04w
3400 = w
Use of 3400 cubic feet of water would lead to a bill of $216.

Erica bought a pencil, a rubber and a ruler for £1. Fritz bought three pens for 75p. Geraldine bought two rubbers and a pen for 45p. Horace bought a pencil, a ruler and a pen.
Answer:
Okay so, one pen equals to 25p, one rubber equals to 10p, and Erica bought a pencil, a rubber, and a ruler for 1 pound, which means 25p+10p equals to 35p, and 100-35= 65p, so one ruler costs 65p, so Horace bought a pencil, a ruler and a pen, we know one pencil equals 25p, a ruler costs 65p, and a pen also equals 25p, so 25+65+25 = 115, so 1pound 15 p

Mr. Santiago can buy light fixtures in packages of 12 and light bulbs in packages of 9. He bought the fewest number of light fixtures and light bulbs so that there is exactly one bulb per fixture with none left over.
How many packages of light fixtures and how many packages of light bulbs did Mr. Santiago buy?

List the multiples of both 12 and 9:
12, 24, 36, 48, 60
9, 18, 27, 36, 45
The lowest common multiple is 36.
This will make the fixtures and bulbs equal.
This means they bought 3 packages of light figures 3 x 12 = 36)
And bought 4 packages of bulbs ( 4 x 9 = 36)
Find out LCM of 9,12
LCM=2(2)(3)(3)=36Now
No of light packages=36/12=3
No of light bulbs=36/4=9

0.546 = 0.4 + ? + 0.006
Please Explain the Answer to me!
Answer: ? = 0.14
Step-by-step explanation:
So you need to find the value that fits the question mark. This means you have to get it by itself.
To start you subtract 0.4 from 0.546, which equals .146. Then you subtract 0.006 from 0.146 to get 0.14
What it looks like mathematically :
0.546 = 0.4 + ? + 0.006
0.146= ? + 0.006
0.14=?

The length of a rectangle is 2 more than twice the width. If the perimeter of the rectangle
is 34 inches, what is the area of the rectangle?
Answer:
Area = WxL=60 square inches
W = 5 inches
L = 12 inches
Step-by-step explanation:
Note, some teachers take points off if you don't include units!!
L = 2W+2
W = W
34 = 2L + 2W (perimeter)
34 = 2(2W+2) +2W solve for width
34 = 4W+4+2W = 6W+4
30 = 6W, so W=5
L = 2(5) +2 = 12
A pair of jeans is on sale for 25% off the original price. Which expression represents the sale
price? If the original price of the jeans is $40, evaluate the expression to find the sale price.
O s=p-0.25p; $30
O s= p - 25; 515
O s = p -0.25p; 510
O s=p-0.25: $39.75
Answer:
$30
Step-by-step explanation:
If it's 25% off, then to find the sale price we just need to subtract 25% of the original price from the original price.
Original price is 40 so we do 40 - (40 * 0.25) = 30
simplify -5^2-2^4

How do you convert 0.580 (80repeating) as a fraction?
Answer:
58/100
Step-by-step explanation:
9514 1404 393
Answer:
115/198
Step-by-step explanation:
The repeat is 2 digits, so you can multiply the number by 10 to that power.
x = 0.58080...(2-digit repeat)
100x = 58.08080...(2-digit repeat)
Then subtract the original number.
100x -x = 99x = 58.08080... -0.58080... = 57.5
Now, divide by the coefficient of x.
x = 57.5/99 = 115/198
This fraction cannot be reduced, so is the fraction you're looking for.
0.580...(2-digit repeat) = 115/198
_____
Additional comment
The number of 9s in the denominator is the number of repeating digits. If the repeat started at the decimal point, the fraction would be those two repeating digits divided by two 9s (99).
Your number can be considered to be ...
0.58080...(2-digit repeat) = 0.5 + 0.0808...(2-digit repeat)
This will be ...
0.58080... = 1/2 + 8/99 = 99/198 +16/198 = 115/198

Tames is six years older
than Peter and the average
of their ages is twice peter age.
How old are they
Answer:
3 and 9
Step-by-step explanation:
let Peter's age be x then James is x + 6
The average of their ages is twice Peter's age, that is
[tex]\frac{x+x+6}{2}[/tex] = 2x
[tex]\frac{2x+6}{2}[/tex] = 2x
x + 3 = 2x ( subtract x from both sides )
3 = x
Then Peter is 3 years old and James is x + 6 = 3 + 6 = 9 years old
The average yearly cumulative rainfall in Tucson by month is shown in the graph below. Does this
graph represent cumulative rainfall as a function of the day? Why or why not? What is the average
annual cumulative rainfall in Tucson? What is the approximate average rainfall in December? During
which month is average rainfall the greatest? How do you know?
Answer:
The average annual cumulative rainfall is [tex]1[/tex] inch per month.
During month of August average rain fall is greatest because slope in this month is maximum.
Step-by-step explanation:
The graph does not represent cumulative rainfall as a function of day.
Because they have average all values for month Total cumulative rainfall is [tex]12[/tex] inches.
Total period is [tex]12[/tex] month
So average annual cumulative rainfall is
[tex]$12 / 12=1$[/tex] inch per month
Average rain fall in month of December= (average cumulative rainfall in December[tex])-([/tex]average cumulative rainfall in November)
[tex]=12-11[/tex]
[tex]$=1$[/tex] inch
During month of August average rain fall is greatest because slope in this month is maximum.
