Answer:
68 km
Step-by-step explanation:
Actual distance (d) will be proportional to the map distance.
d/8.5 = 36 km/4.5
d = (36 km)(8.5/4.5) = 68 km
The actual distance is 68 kilometers.

f(n) = n^3– 2n
g(n)= 2n + 2
Find (f •g)(n)
Answer:
[tex]\boxed{(f~.~g)(x) = 2n^4 + 2n^3 - 4n^2 -4n}[/tex]
.
Step-by-step explanation:
We know that
[tex]f(n) = n^3 - 2n[/tex]
[tex]g(n) = 2n + 2[/tex]
.
So
[tex](f~.~g)(x) = f(n)~.~g(n)[/tex]
[tex](f~.~g)(x) = (n^3-2n)(2n + 2)[/tex]
[tex](f~.~g)(x) = n^3(2n + 2) - 2n(2n + 2)[/tex]
[tex](f~.~g)(x) = 2n^4 + 2n^3 - 4n^2 -4n[/tex]

(2x+3y)raise 2 pls can u tell
Answer:
4x² + 12xy + 9y²
Step-by-step explanation:
Assuming you require the expansion
(2x + 3y)²
= (2x + 3y)(2x + 3y)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x + 3y) + 3y(2x + 3y) ← distribute both parenthesis
= 4x² + 6xy + 6xy + 9y² ← collect like terms
= 4x² + 12xy + 9y²
Answer:
[tex] {4x}^{2} + 12y + {9y}^{2} [/tex]
Step-by-step explanation:
[tex](2x + 3y) {}^{2} \\ {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} \\ = {(2x)}^{2} + 2 \times 2x \times 3y + {(3y)}^{2} \\ = 4 {x}^{2} + 12y + 9 {y}^{2} \\ hope \: it \: helps[/tex]
Jack bought 3 pairs of socks for $7.50. At this rate, how much would 10 pairs of socks cost?
Answer:
25$
Step-by-step explanation:
7.50$ divided by 3 is 2.50$. then 2.50$ times 10 is 25$
Answer:
75$
Step-by-step explanation:
because you multiply 7 x 10 and that equals 70$ and then multiply .50 x 10 and that equals 5$ so 70$ plus 5$ equals 75$

Step-by-step explanation:
Francisco is saving money in an account. At the beginning of the year, he has $56 in savings
and puts in another s4 per week. Which of the following equations models the amount of
savings, s, as a function of the number of weeks, w, Francisco has been saving?
The correct equation for this given condition is;
⇒ s = $56 + $4w
Where, 's' is amount of savings and 'w' is number of weeks.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Francisco is saving money in an account.
The savings amount = $56
And, Put in another $4 per week.
Now,
Let number of weeks = w
And. Total amount in saving amount = s
So, We can formulate;
⇒ s = $56 + $4w
Thus, The correct equation for this given condition is;
⇒ s = $56 + $4w
Where, 's' is amount of savings and 'w' is number of weeks.

Solve for the variable x.
4(x - 11) = -210
Answer: Divide both sides by the numeric factor on the left side, then solve.
Exact Form: x= −83/2
Answer: x = -41.5
Step-by-step explanation:
Distribute the 4 that is outside of the parentheses.
4 times x = 4x
4 times -11 = -44
Then to isolate the variable add 44 to both sides of the equation to cancel out -44.
-44 + 44 = 0
-210 + 44 = -166
Now your equation should 4x = -166
To find x, divide both sides of the equation by 4.
4x divded by 4 is x.
-166 divded by 4 is -41.5.
So the answer is x = -41.5.
To check the answer, plug in -41.5 to the x.
4(-41.5 - 11) = -210
i need help findind m angle 12 =?
m angle 9 = 80° and m angle 5= 68°
Answer:
I think the answer is 12 = 100
Step-by-step explanation:
since 9 = 80 and that is the same for 11, if you do 180 - 80 = 100 which would be the answer for 10 and 12. Thus 12 = 100 based on the info given.

Use the algebraic expressions for the length and width of Marlene's living room found in the
23.
diagram and the value of x found in Question 21C.
A. Find the actual length and width of her living room.
B
Find the actual area of Marlene's living room. Use actual dimensions.
Answer:
The area of Marlien's living room is 420 square ft
Step-by-step explanation:
Before calculating the real dimensions of Marlien's living room, we must find the value of x.
Given the total shape of the house is a rectangle, then both widths must be equal and both lengths must be equal.
The widths are already written width identical expressions x-2+x, but the lengths are given as different functions of x. Equating both expressions, we have:
[tex]2x-10+x-2+\frac{1}{2}x-4+x-2=2x+2+\frac{1}{2}x-4+x-2[/tex]
Simplifying:
-10 + x - 2 = 2
x = 10 + 2 + 2
x = 14
Since x=14 feet, the dimensions of Marlien's living room are
width=x=14 feet
length=2x+2=30 feet
Thus the area is:
A = 14*30 = 420 square ft
The area of Marlien's living room is 420 square ft

Company sells drinks in packs and cases a bottle is 1/6 of pack and the pack is 1/12 of a case a case of the drink called 25.92 what is the price per bottle in a case
Answer:
0.36
Step-by-step explanation:
Company sells drinks in packs and cases a bottle is 1/6 of pack and the pack is 1/12 of a case a case of the drink called 25.92 what is the price per bottle in a case
From the above question:
1 pack = 1/12 of a case.
1/12 of a case = 1 pack
1 case = x packs
Cross Multiply
1/12 × x = 1 × 1
x = 1 / 1/12
x = 1 × 12/1
x = 12 packs
This means, 1 case of drinks contains 12 packs of drinks
We are also told that: a case of the drink cost 25.92
This means the cost of 12 packs of drinks = 25.92
We are also told that:
a bottle is 1/6 of pack
1/6 pack = 1 bottle
1 pack = x bottles
Cross Multiply
1/6 × x = 1 × 1
x = 1 / 1/6
x = 1 × 6/1
x =6 bottles
This means, 1 pack of drinks contains 6 bottles of drinks
Hence:
12 packs of drinks = 25.92
1 pack of drinks = x
Cross Multiply
12x = 25.92
x = 25.92/12
x = 2.16
1 pack of drinks cost 2.16= 6 bottles of drinks cost 2.16
Therefore:
6 bottles of drinks = 2.16
1 bottle of drink = x
Cross Multiply
6x = 1 × 2.16
x = 2.16/6
x = 0.36
Therefore, the price per bottle in a case is 0.36
a coin jar holds dimes and quarters.A coin jar holds dimes and quarters. There are ten less quarters than dimes. There is a total of $3.80. How many dimes are in the jar
Answer:
There are 18 dimes in the jar
Step-by-step explanation:
Let
x = number of dimes in the jar
y = number of quarters in the jar
Total = $3.80
There are ten less quarters than dimes
y = x - 10
0.1x + 0.25y = 3.80
0.1x + 0.25(x - 10) = 3.80
0.1x + 0.25x - 2.5 = 3.80
0.35x = 3.80 + 2.5
0.35x = 6.30
x = 6.30/0.35
x = 18

Alex is trying to run a certain number of miles by the end of the month Alex is 40% of the way to achieving her goal and she already has run 12 miles how many miles is she trying to run by the end of the month
Answer:
30 miles
Step-by-step explanation:
Given that:
Alex has some target to run a certain number of miles by the end of the month.
Goal already achieved = 40% of the total goal
Number of miles already run by Alex = 12 miles
To find:
Number of miles that Alex is trying to run by the end of month?
Solution:
We have to find nothing but the goal of Alex here.
Let the number of miles that Alex is trying to run by the end of the month = [tex]x[/tex] miles
As per question statement:
40% of total number of miles to be run = 12 miles
OR
[tex]\dfrac{40}{100}\times x = 12\\\Rightarrow 40x=12\times 100\\\Rightarrow x = \dfrac{1200}{40}\\\Rightarrow \bold{x = 30\ miles}[/tex]
Total number of miles that Alex is trying to run by the end of the month = 30 miles

What is the area of the figure composed of a parallelogram, a square, anda rectangle?
10 in.
3.5 in.
4 in.
6 in.
12.5 in.
Enter the answer in the box.
___ square inches
Answer:
126 in^2.
Step-by-step explanation:
Area of parallelogram = 10 * 3.5 = 35.
Area of the square = 4*4 = 16.
Area of the rectangle = 6 * 12.5 = 75
Total area = 35 + 16 + 75
= 126 in^2.

The sum of the first a teoms of on
A
is 214. Find the frost 4 teams,
Answer:
So you have a summation of 4 terms
An Easy way to do this is to simplify the process:
You need X1+X2+X3+X4 to equal 214
Let the first number be 80
80+X2+X3+X4
Let X2 and X3 be 60 each
80+ 60+ 60+X4
Lastly we are at a sum of 200
So let X4 be 14
Therfore we have a sum of 4 X terms equal 214
