The volume of a cube is related to the area of a face by the formula V = A 3 2 . What is the volume of a cube whose face has an area of 81 cm2?
Answers
Step-by-step explanation:
We have V=A3/2
We know that A = 100cm2, so just plug the area into the equation:
V = 1003/2
= 1002/2 * 1001/2
= 100 * √(100)
= 100 * 10 = 1000 cm3
Therefore, the area is 1000cm3
Another way to solve the problem is to figure out what the side length is from the area. Since the area is 100cm2, and we know that area of a cube face is s2 (where s is the length of the side), we can figure out the side length first like this:
s = √(100cm2)
s = 10cm
Then we can calculate volume using V = s3 = 1000 cm3

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?
Answers
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).

0.546 = 0.4 + ? + 0.006
Please Explain the Answer to me!
Answers
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=?

How do you convert 0.580 (80repeating) as a fraction?
Answers
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

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?
Answers
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.

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) 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
Answers
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.
