Alaina is helping to build a new room in her house. The length of the room will be 12 feet. Three feet is about 0.9144meters so about how many meters will the length of the room measure? Round to the nearest hundredth.
Answer: 3.66m
Step-by-step explanation:
If 3 feet is 0.9144 and you have 12ft, you first need to divide the 12 by 3 and you get 4. Now that you have the scale factor you multiply the 0.9144 by 4 and you get 3.6576 but they want it to the nearest hundredth (second number after the decimal point) so the answer will be 3.66m
Find the slope that passes through the line (9, 3) and (2, 7)
Answer:
-4 / 7
Step-by-step explanation:
m = (y2 - y1) / (x2 - x1)
m = (7 - 3) / (2 - 9)
m = 4 / -7
m = -4 / 7
OR
m = (y2 - y1) / (x2 - x1)
m = (3 - 7) / (9 - 2)
m = -4 / 7

I need help writing an equation.
Subtraction Equation:
One arrow from the line 0 decreasing towards -9 (negative nine).

Notice: I am not responsible for any plagarism, it is your choice to use it, or correct partial of it. I also created a subtraction equation only certainly because it seems like it would make more sense. Not only that, it seems like it's the only possible solution that can be distributed.

Find the slope of the line that passes through the two points.
(-2,-8) and (4,4)
Answer:
The slope is 2
Step-by-step explanation:
Basically its Point slope form. Couldn't get their equation creator to work properly. Anyway....
(-2,-8) becomes the first set of x and y
(4,4) becomes the second set of x and y
For numerator.......4- -8=12
For denominator.......4- -2=6
12/6=2
The slope is 2

The inner circumference of a hollow cylindrical pipe is 4.5 metres and outer circumference is 4.6 metres. Find the cost of painting both its inner and outer sides at the rate of 20 per metre square, if it is 8 metres tall.
Answer:
[tex]\$527.2[/tex]
Step-by-step explanation:
[tex]r_i[/tex] = Inner radius
Inner circumference = 4.5 m
[tex]2\pi r_i=4.5\\\Rightarrow r_i=\dfrac{4.5}{2\pi}\\\Rightarrow r_i=\dfrac{2.25}{\pi}[/tex]
[tex]r_o[/tex] = Outer radius
Outer circumference = 4.6 m
[tex]2\pi r_o=4.6\\\Rightarrow r_o=\dfrac{4.6}{2\pi}\\\Rightarrow r_o=\dfrac{2.3}{\pi}[/tex]
h = Height of cylindrical pipe = 8 m
Total surface area to be painted
[tex]s=\pi r_i^2h+\pi r_o^2h\\\Rightarrow s=\pi h(r_i^2+r_o^2)\\\Rightarrow s=\pi\times 8((\dfrac{2.25}{\pi})^2+(\dfrac{2.3}{\pi})^2)\\\Rightarrow s=26.36\ \text{m}^2[/tex]
Cost of painting 1 square meter is 20
Cost of painting the inner and outer surfaces is [tex]20\times 26.36=\$527.2[/tex]
The total cost painting the surfaces is [tex]\$527.2[/tex].

Destiny made a password that consists of 4 digits, 0-9. None of the digits are the same How many passwords are possible?
Answer:
5,040
Step-by-step explanation:
10x9x8x7 = 5,040
Using the permutation formula, it is found that 5040 passwords are possible.
The order is important, as 1234 is a different password than 2134, for example, hence the permutation formula is used to solve this question.
What is the permutation formula?The number of possible permutations of x elements from a set of n elements is given by:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this problem, 4 digits are taken from a set of 10, hence:
[tex]P_{(10,4)} = \frac{10!}{6!} = 5040[/tex]
5040 passwords are possible.

Find the new set of coordinates given the scale factor for k > 1. E = (-1, -2), F = (2, -5), G = (5, -1), H = (1, 1) Scale factor = 6 E'= F' = G' = H' =
Answer:
The new set of coordinates are [tex]E'(x,y) = (-6,-12)[/tex], [tex]F'(x,y) = (12,-30)[/tex], [tex]G'(x,y) = (30,-6)[/tex] and [tex]H'(x,y) = (6,6)[/tex].
Step-by-step explanation:
Vectorially speaking, dilation can be defined by this equation:
[tex]D'(x,y) = O(x,y) +k\cdot (D(x,y)-O(x,y))[/tex] (1)
Where:
[tex]O(x,y)[/tex] - Center of dilation.
[tex]D(x,y)[/tex] - Original point.
[tex]k[/tex] - Scale factor.
[tex]D'(x,y)[/tex] - Dilated point.
Let suppose that center of dilation is located at origin, we determine the new set of coordinates below:
[tex]E'(x,y) = O(x,y) +k\cdot (E(x,y)-O(x,y))[/tex]
[tex]E'(x,y) = (0,0) +6\cdot (-1,-2)[/tex]
[tex]E'(x,y) = (-6,-12)[/tex]
[tex]F'(x,y) = O(x,y) + k\cdot (F(x,y)-O(x,y))[/tex]
[tex]F'(x,y) = (0,0) +6\cdot (2,-5)[/tex]
[tex]F'(x,y) = (12,-30)[/tex]
[tex]G'(x,y) = O(x,y) + k\cdot (G(x,y)-O(x,y))[/tex]
[tex]G'(x,y) = (0,0) + 6\cdot (5,-1)[/tex]
[tex]G'(x,y) = (30,-6)[/tex]
[tex]H'(x,y) = O(x,y) +k\cdot (H(x,y)-O(x,y))[/tex]
[tex]H'(x,y) = (0,0) + 6\cdot (1,1)[/tex]
[tex]H'(x,y) = (6,6)[/tex]
The new set of coordinates are [tex]E'(x,y) = (-6,-12)[/tex], [tex]F'(x,y) = (12,-30)[/tex], [tex]G'(x,y) = (30,-6)[/tex] and [tex]H'(x,y) = (6,6)[/tex].

Dave took 8/9 of his savings and decided to invest it. With his investments, 2/3 of it will go into the Canadian stock market. Amongst his Canadian stocks, 1/2 of it will be invested into oil companies. If Dave had $100,000 in his savings account, how much did he invest into Oil companies?
a) Write an equation to represent the scenario
b) Solve the equation and find out how many bags he can make:
Answer:
Dave invested approximately $29,629.63 into Oil companies.
Step-by-step explanation:
8/9 (100,000) = i
i= $88,888.89
2/3(88,888.89)=c
c = $29,259.26
1/2(29,259.26)=o
o= $29,629.63

( D. 10 - 6x)
The expression equivalent to 4(6 -2x) is A. 24 - 8x.
What is an expression?An expression is a sentence in two or more than two variables separated by addition or subtraction or both. There are many types of mathematical expressions they are algebraic expressions, trigonometric expressions, logarithmic expressions, and many more.There are also three basic math properties they are commutative law which states a + b = b + a, associative law which states (a+b) + c = a + (b+c) and distribute law which states a(b+c) = ab + ac.
We know distributive property states that a(b+c) = b + bc.
∴ The expression 4(6 -2x) is equivalent to,
= 24 - 8x.
