Step-by-step explanation:
12- 1/5r = 2r + 1
R=??
Answer:
r = 5
Step-by-step explanation:
12 - 1/5r = 2r + 1
12 - 0.2r = 2r + 1
12 - 0.2r + 0.2r = 2r + 0.2r + 1
12 = 2.2r + 1
12 - 1 = 2.2r + 1 - 1
2.2r = 11
2.2r ÷ 2.2 = 11 ÷ 2.2
r = 5
Answer:
r = 5
Step-by-step explanation:
12- 1/5r = 2r + 1
12 = 11/5r + 1
5(11) = (11/5r)5
55 = 11r
r = 5

A swimming pool has a diameter of 24 feet. What is the minimum amount of fabric needed to cover the pool if the cover must hang off by 1 foot all around the pool?
Answer:
531.167 ft²
Step-by-step explanation:
Given data
Dimension of pool
Diameter =24ft
Radius =12ft
If the cover must hang by 1ft around, then the diameter is 26ft
Radius =13ft
Area of cover = πr²
Substitute
Area = 3.142*13²
Area =3.143*169
Area =531.167 ft²
Hence the minimum area is 531.167 ft²

Answer:
Hi there, this should be the correct answer!
x = -1 - 1/2y
y = -2 - 2x
Step-by-step explanation:
Work I did, hope this helps:
y + 4 = -2x + 2

The surface area of a cube is S(x) = 6x?, where x is the length of the side of each edge of a cube, Restrict the domain to create a one-to-one
function. Find and describe the inverse function.
Answer:
Restrict values of x to . Then the surface area function is one-to-one and has an inverse.
Write y instead of S(x). Interchange x and y, then solve for y.
This function could be used to find the edge of a cube with a given surface area. For example, if the area is x = 54, then the edge is

A chair rental company charges $100 for delivery plus $3 per chair.
You have $410 to spend on chairs. How many can you rent?
Answer:
103 chairs
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
410 = 100 + 3*c
Subtract 100 from each side
410-100 = 100+3c-100
310 = 3c
Divide by 3
310/3 = 3c/3
103.3=c
We cannot rent part of a chair so we round down
103 chairs

You have a 3L jug and a 5L jug. You need to fill the 5L jug with exactly 4L of water. Write an algorithm to solve this problem. I will award Brainliest!
Fill the 3L jug, then pour its contents into the 5L jug.
Fill the 3L jug again, then pour as much of it (2L) as you can into the 5L jug.
Now the 5L jug is full, and the 3L jug is carrying 1L of water.
Empty the 5L jug.
Pour the 1L of water from the 3L jug to the 5L jug.
Finally, fill up the 3L jug, then transfer its water into the 5L jug. It now has 4L of water.

Write an equation for the nth term of the arithmetic sequence. -6,-9,-12,-15
Answer:
[tex]a_{n}[/tex] = - 3n - 3
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 6 and d = a₂ - a₁ = - 9 - (- 6) = - 9 + 6 = - 3 , then
[tex]a_{n}[/tex] = - 6 - 3(n - 1) = - 6 - 3n + 3 = - 3n - 3

Answer:
2 degrees / hour
Step-by-step explanation:
The average rate of change is
f(x2) - f(x1)
---------------
x2 -x1
We know that x2 is 6pm so f(x2) is 101
We know that x1 is 10 am so f(x1) is 85
101 -85
--------------
6 pm - 10 am
16 degrees
---------------
8 hours
2 degrees / hour
Answer:
We have this proportion....
36 / 12 = x / 9 where x is the model door height
Cross-multiply
36*9 = 12 * x
324 = 12 *x divide both sides by 12
27 = x and that's the model height in centimeters

What is the domain of the function graphed below?
Answer:
x < 7
Step-by-step explanation:
the domain is the number range or interval of x the function is defined for to generate a y-value.
the graph shows that the y-values continue with x-values to the right up to but not including 7 (the empty dot says "excluding"). and with x- values to the left to negative infinity.
x=-1 is not a problem, because while for the left part of the function it is not included, but for the right part it is.
so, it is fully defined for all x < 7.
