This pool has a deep end and a shallow end.The pools perimeter is 70 ft.Hiw wide is the deep end,d?
Answers
Work Shown:
L = d+9 = length along the horizontal
W = 10 feet = width along the vertical
P = 2(L+W) = perimeter of rectangle = 70 feet
70 = 2(d+9+10)
70/2 = d+19
35 = d+19
d+19 = 35
d = 35-19
d = 16
The deep end is 16 feet wide

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

describe fully the single transformation that maps triangle a onto triangle b
Answers
Answer:
the triangle A is translation to the triangle B.
Step-by-step explanation:
The ratio of x-coordinates is 4 /7 = 1.75 , so the scale factor of the dilation that maps (4,6) onto (7,9) is 1.75.
So, translation: (x,y) ↦ (x−2,y−1)
Tames is six years older
than Peter and the average
of their ages is twice peter age.
How old are they
Answers
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

square millimeters
Answers
Answer:
107 square millimeters
Step-by-step explanation:
You can make this problem easier by splitting this into pieces you already know how to solve. So, you can draw a line down the middle to get 2 rectangles whose formula are Length X Width. Now, use the side lengths 5x7=35 and 8x9=72.
Add the 2 area of rectangles together to get 107 which is your total area.
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?
Answers
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
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.
Answers
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
Step-by-step explanation:
E is the midpoint of DF, DE = 3x + 4 and EF = 5x - 2. Find DE, EF, and DF.
Answers
Since E is the midpoint of DF, DE and EF are two halves of DF. First, let's write down what we know.
DE = 3x + 4
EF = 5x - 2
DE = EF
DE + EF = DF
Now, let's plug our values for DE and EF into our first expression.
3x + 4 = 5x -2
Add 2 to both sides and subtract 3x from both sides.
6 = 2x
Divide both sides by 2
3 = x
Let's plug 3 in for x into DE.
DE = 3x + 4 = 3(3) + 4 = 9 + 4 = 13
DE = EF = 13
We can plug 13 in for DE and EF to get DF
DF = DE + EF = 13 + 13 = 26

The equation of the graph shown below could be A or C.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Linear equations may include one or more variables.
Given is a graph of the line.
So the equation must be linear.
The slope intercept form of a line is,
y = mx + c, where m is the slope and c is the y intercept.
The given graph has a negative slope since the graph is decreasing.
That is, the value of y is decreasing with an increase in the value of x.
m is negative.
Find the equations of line in options with negative slope.
Possible options are A and C.
A : y = -2x + 5
C : 2x + y = 4 ⇒ y = -2x + 4
Hence the possible options are A or C.

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
Answers
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
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.

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=?
Hopes this helps :)
