What is the answer 2-2n=3n+17
Answers
Answer:
n=-3
Step-by-step explanation:
2-2n=3n+17
Add 2n to each side
2-2n+2n=3n+2n+17
2 = 5n+17
Subtract 17 from each side
2-17 = 5n+17-17
-15 = 5n
Divide by 5
-15/5 = 5n/5
-3 =n
Answer:
n = -3
Step-by-step explanation:
2 - 2n = 3n + 17
Collect the like terms
-2n - 3n = 17 - 2
-5n = 15
Divide both sides by -5
n = 15/-5
n = -3

Area of the larger circle is 9/4 πx²
Step-by-step explanation:
Step 1: Given area of the small rug = 1/4 πx² Compare this to the formula for area of a circle.⇒ 1/4 πx² = πr²
⇒ x²/4 = r²
∴ r = x/2
Step 2: Given radius of the larger circle is 3 times that of the smaller circle (r = 3x/2), find area of the larger circle.Area of the larger circle = πr² = π × (3x/2)²
= 9/4 πx²

Answers
Answer:
C
Step-by-step explanation:
The high school boys vary in height more than the middle school boys.
middle school boys range = 169 − 164 = 5 cm
high school boys range = 183 − 175 = 8 cm
The range for both conditions is 5 cm and 8 cm respectively.
What is the range?The difference between the highest and lowest value data points of the provided data is known as the range in mathematics.
In statistics, the mean is the product of all the values in a set of data divided by the total number of values in the data for a given set of observations.

a group of rangers work 5 days per week. it takes them 4 days to plant trees on 1/2 acre.what is the unit rate per week
Answers
The unit rate at which the group of rangers plants trees is 5/8 of an acre per week, which is found by calculating the daily acreage planted and then multiplying by the number of workdays in a week.
Explanation:To determine the unit rate per week of the group of rangers planting trees, we need to calculate how much of an acre they can plant in a standard work week. As it takes them 4 days to plant trees on 1/2 acre, they will plant 1/2 acre in every 4 days of work. Since they work 5 days per week, we can adjust the ratio to calculate the weekly rate:
1/2 acre in 4 days is equivalent to (1/2 acre)/(4 days).Now, find out how much is planted in 1 day: (1/2 acre)/(4 days) = 1/8 acre in 1 day.Finally, multiply by 5 to get the weekly amount: (1/8 acre) * 5 days = 5/8 acre per week.Therefore, the unit rate at which the group of rangers plants trees is 5/8 of an acre per week.
let f(7)=12 and g(2)=7 what is the value of (f•g)(2)
Answers
Final answer:
The value of (f•g)(2), given f(7)=12 and g(2)=7, is 12. This is found by first applying g to 2 to get 7, and then applying f to get f(7), which equals 12.
Explanation:
The question pertains to the composition of functions and the use of the chain rule in calculus. Given that f(7)=12 and g(2)=7, we need to find the value of (f•g)(2). The notation (f•g)(x) means we first apply g to x, and then apply f to the result of g(x). Therefore, to find (f•g)(2), we first find g(2), which is 7, and then find f(g(2)) which is f(7). Since we know that f(7)=12, the value of (f•g)(2) is therefore 12.

high. Note: this drawing is not to scale)
How many square feet of wallpaper are needed to cover the wall?
Answers
84 sq. ft of the wall has to be covered with paint or wallpaper.
Step-by-step explanation:
Step 1: Find the area of wallpaper to be covered by calculating the area of the wall and subtracting the areas of the window, mirror and fireplace from it. All are rectangular in shape with are given by A = length × widthArea of the wall = 8 × 16 = 128 ft²
Area of the window = 18/12 × 14 = 1.5 × 14 = 21 ft² (since 1 ft = 12 in)
Area of the fireplace = 5 × 3 = 15 ft²
Area of the mirror = 4 × 2 = 8 ft²
Step 2: Calculate the area to be painted or covered with wallpaperArea of the wall to be covered with paint or wallpaper = 128 - (21 + 15 + 8)
= 128 - 44
= 84 ft²
Answer:
84 ft²
Step-by-step explanation:
Step 1: Find the area of the wall.
The wall is 8 ft high and 16 ft wide
A = LW
A = (16)(8)
A = 128 ft²
Step 2: Find the area of the window, fireplace, and mirror.
Window: The window measures 18 in wide and 14 ft high
18 in = 1.5 ft
A = LW
A = (14)(1.5)
A = 21 ft²
Fireplace: The fireplace is 5 ft wide and 3 ft high
A = LW
A = (3)(5)
A = 15 ft²
Mirror: The mirror above the fireplace is 4 ft wide and 2 ft high
A = LW
A = (2)(4)
A = 8 ft²
Step 3: Add all the areas of the three objects (window, fireplace, and mirror)
A = 21 + 15 + 8
A = 36 + 8
A = 44 ft²
Step 4: Subtract the total area of the objects from the area of the wall.
A = 128 ft² - 44 ft²
A = 84 ft²

Pamelas age is. 2 times jiris age. The sum of their ages is 30.what is jiris age?
Answers
p = Pamela’s age, j = Jiris’ age
2j = p
p + j = 30
Then change things around a bit...
p + j = 30 or
30 - p = j
Then substitute
2(30 - p) = p
And solve
2(30 - p) = p
60 - 2p = p
60 = 3p
p = 20
Answer:
Pamela is 20 years old
Jiris is 10 years old.
Step-by-step explanation:
The very first step is to identify your variables. Let's say that Pamela is 'P' and lets say Jiris is 'J.' The next step is to create an equation. 'The sum of their ages is 30' is something that we can use. So, P + J = 30. The next step is to see that Pamela is two times Jiris' age. So we can say that P = 2J. Now, in order to solve for one variable, we need to do some substitution. We know that P = 2J, so we can plug that into the first equation (P + J = 30). With this change, we now have, 2J + J = 30. With that, you combine like terms and solve for J to get an answer of J = 10. Now we can use that number and plug it into one of our previous equations, like P + J = 30. Now it is going to be P + 10 = 30. Solve for P and get an answer of 20 years old.

Each of the letters of the word ALABAMA are written on a piece of paper and then put into a bag. A piece of paper is drawn at random. What is the theoretical probability, as a decimal, of drawing an A? Round the decimal to the nearest hundredth.
Answers
The theoretical probability of drawing an 'A' from the word 'ALABAMA' is 0.57. This result arrives from dividing the number of 'A's (4) by the total number of letters in 'ALABAMA' (7).
Explanation:The question deals with a probability problem related to the selection of letters from the word 'ALABAMA'. The word 'ALABAMA' has 7 letters out of which 4 are 'A's. The theoretical probability is calculated as the number of successful outcomes divided by the total number of outcomes. Since we are interested in drawing an 'A', the successful outcomes are the number of 'A's which is 4, and the total outcomes are the total number of letters which is 7.
To calculate theoretical probability, you divide the number of successful outcomes by the total number of outcomes. In this case, the calculation will be 4 / 7 = 0.57 (rounded to the nearest hundredth).
So, the theoretical probability of drawing an A from the word 'ALABAMA' in decimal form, rounded to the nearest hundredth, is 0.57.

What is the volume, in cubic m, of a cube with an edge length of 11m?
Answers
the volume of cube with edge length 11 m is [tex]Volume = 1331m^3[/tex] .
Step-by-step explanation:
Here we have a side length of a cube as 11 m . We need to find the volume of cube . Let's find out:
We know that every side of a cube is identical and equal . And volume of cube is given by formula :
⇒ [tex]Volume = (side)^3[/tex] ...........(1)
According to question we have following parameters as
[tex]side = 11m[/tex]
Putting this in (1)
⇒ [tex]Volume = (11m)^3[/tex]
⇒ [tex]Volume = 11(11)(11)m^3[/tex]
⇒ [tex]Volume = (121)(11)m^3[/tex]
⇒ [tex]Volume = 1331m^3[/tex]
Therefore , the volume of cube with edge length 11 m is [tex]Volume = 1331m^3[/tex] .
The volume of the cube is 1331 m³
Explanation:
Given:
side of the cube, a = 11m
Volume of the cube, v = ?
we know:
Volume of the cube = (a)³
V = (11m)³
V = 1331 m³
