Express 120 as the product of its prime factors.
Write the prime factors in ascending order.
Answer:
2 x 2 x 2 x 3 x 5
Step-by-step explanation:
The first and smallest prime number that can be divisible by 120 is 2; 120/2 = 60, 60/2 = 30, 30/2 = 15; and the smallest prime number divisible by 15 is 3; 15/3 = 5; and the smallest prime number divisible by 5 is 5; 5/5 = 1.
hence, we have 2 x 2 x 2 x 3 x 5 = 2³ x 3 x 5

We can plot these two points and draw a line through them to get the border of the inequality:
graph{(x^2+(y-2)^2-0.075)((x-4)^2+y^2-0.075)(x+2y-4)=0}
The line will be solid because the inequality operator has a "or equal to" clause in it. We can now shade the area to the right of the line because the inequality has a "great than" clause in it.
graph{(x+2y-4)>=0}

Answer:
"A"
Step-by-step explanation:
C & D start at 12... story starts at 15
3*3600 = 10,800 .... 15,000-10,800 = 4200
at 3 the graph has to be at 4200 (which is above 3)
note at 3 "B" is at 3 so answer has to be "A"

find the area of the Shaded sector. round to the nearest hundreds place
HELP!!! ASAP
Answer:
[tex]192.27\:\mathrm{cm^2}[/tex]
Step-by-step explanation:
The area of sector with radius [tex]r[/tex] and measure [tex]\theta[/tex] is give by [tex]A=r^2\pi\cdot \frac{\theta}{360^{\circ}}[/tex]. Since vertical angles are congruent, the two shaded sectors in the figure are congruent.
What we're given:
2 sectors of equal areaEach sector has a radius of 9 cmEach sector has a measure of 136 degreesTherefore, the area of the shaded regions (two sectors) is:
[tex]A=2\cdot 9^2\pi\cdot \frac{136}{360}=192.2654704\approx \boxed{192.27\:\mathrm{cm^2}}[/tex]

Please help me figure out this problem
Answer:
There was no van stated in the question, but if the van was the truck, the answer would be $50.
Step-by-step explanation:
We can split the problem into 2 parts. First, there is a flat fee of $30 to rent the truck.
Now, we can calculate the cost to rent the truck for 80 miles excluding the flat fee by multiplying the values together.
$0.25/mile * 80 miles = $20
Now, we can add the values up.
This will give us: $30 + $20 = $50

Help and explain pleaseeeeeeeee
Given:
The function is:
[tex]f(x)=\{(1,0),(2,3),(3,6)\}[/tex]
The given function is:
[tex]f(x)=1-2x[/tex]
The range of this function is [tex]\{-3,-5,-7\}[/tex].
To find:
The range of first function.
The domain of second function.
Solution:
Domain is the set of input or x-values and range is the set of output or y-values.
We have,
[tex]f(x)=\{(1,0),(2,3),(3,6)\}[/tex]
Here, the x-values are 1, 2, 3 and the y-values are 0, 3, 6.
Therefore, the range of the given function is [tex]\{0, 3, 6\}[/tex]. Hence, the correct option is C.
The given function is:
[tex]f(x)=1-2x[/tex] ...(i)
The range of this function is [tex]\{-3,-5,-7\}[/tex].
Putting [tex]f(x)=-3[/tex] in (i), we get
[tex]-3=1-2x[/tex]
[tex]-3-1=-2x[/tex]
[tex]\dfrac{-4}{-2}=x[/tex]
[tex]2=x[/tex]
Similarly,
Putting [tex]f(x)=-5[/tex] in (i), we get
[tex]-5=1-2x[/tex]
[tex]3=x[/tex]
Putting [tex]f(x)=-7[/tex] in (i), we get
[tex]-7=1-2x[/tex]
[tex]4=x[/tex]
The domain of this function is [tex]\{2,3,4\}[/tex]. Hence, the correct option is A.
Which system is equivalent to
Answer:
We can find the system equivalent to this one by replacing one of the equations with a multiply of itself, so:
Let’s multiply y = x-2 by 2
2y=2x-4
A system equivalent to this one is
y = -2x^2 (this remains the same)
2y= 2x-4

Bianca read 5 books last month. The number of pages in each book that bianca read is listed in the box below12,106,94,100,180 what is the mean absolute deviataion of the number of pages in the 5 books bianca read?
Answer:
36.32
Step-by-step explanation:
Given the data:
X = 12,106,94,100,180
The mean absolute deviation is calculated thus :
MAD = |x - mean| / n
Where n = sample size
Mean = Σx / n = (12 + 106 + 94 + 100+ 180) / 5 = 98.4
MAD = (|12 - 98.4| + |106 - 98.4| + |94 - 98.4| + |100 - 98.4| + |180 - 98.4|) / 5
MAD = 36.32
What is the image point (-5,3) if it is translated 3 units right and 2 units down
Our point is at -5, 3. -5 represents its x coordinate, and 3 represents its y coordinate. 3 units right makes it -2, while 2 units down makes it 1. Final coords of the point are (-2,1).
Answer:
given point is (-5,3)
right unit means positive and down unit means negative so,
image of (-5,3)---------->(-5+3-2,3+3-2)

What is the value of k?
Answer:
10
Step-by-step explanation:
Top angle of tri:
180 - 115 =
65
So:
65+4K+5+6k+10 = 180 (angles in tri add to 180)
Solve:
80+10k = 180
10k = 100
K = 10
Answer:
10
Step-by-step explanation:
y = 180 - 115
y = 65
Total of angles in a triangle is 180
(4k + 5) + (6k + 10) + 65 = 180
combine like terms
10k + 80 = 180
Subtract 80 from both sides
10k = 100
Divide both sides by 10
k = 10

Step-by-step explanation:
a) fg(x) = f(x²-1) = 2(x²-1) + 3
= 2x² + 1
b) gf(x) = (2x+3)² - 1
= 4x² + 12x + 9 - 1
= 4x² + 12x + 8
c) fg(2) replace the value in a)
fg(2) = 2(2²) + 1

A rectangular garden has length and width as given by the expressions below.
Length: 4 - 7(3x + 4y)
Width: 3x(-2y)
Write a simplified expression for the perimeter of the rectangle.
y
ху
Answer:
8 - 42x - 56y - 12xy
Step-by-step explanation:
Length = 4 - 7(3x + 4y)
= 4 - 21x - 28y
Width = 3x(-2y)
= -6xy
Perimeter of the rectangle = 2(length + width)
= 2{(4 - 21x - 28y) + ( -6xy)}
= 2(4 - 21x - 28y - 6xy)
= 8 - 42x - 56y - 12xy
Perimeter of the rectangle = 8 - 42x - 56y - 12xy

While she was on holiday,Olga measured the temperature at the same time every day. Here are the results. Work out the median: The range of the temperatures
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the required data are not given.
I will use the following data as an illustration of how to calculate median and range.
We have:
[tex]x: 11, 13, 14, 15, 18, 20[/tex]
Calculate range
Identify the highest and the least
[tex]Highest = 20[/tex]
[tex]Least = 11[/tex]
So, the range is:
[tex]Range = Highest -Least[/tex]
[tex]Range =20-11[/tex]
[tex]Range =9[/tex]
Calculate the median
The number of data we are using is 6 (i.e. even).
So, the position of the median item is:
[tex]Median =\frac{1}{2}(n+1)[/tex]
[tex]Median =\frac{1}{2}(6+1)[/tex]
[tex]Median =\frac{1}{2}*7[/tex]
[tex]Median =3.5th[/tex]
A decimal result implies that the median is the mean of the integer values before and after the result.
In this case, the median is the mean of the item at 3rd and 4th positions.
So:
[tex]Median = \frac{14+15}{2}[/tex]
[tex]Median = \frac{29}{2}[/tex]
[tex]Median = 14.5[/tex]
Find the direct variation equation
Answers:
The direct variation equation is y = 5xIf x = 4, then y = 20=================================================
Explanation:
Let's say that the letter k replaces the green box
We have the equation y = kx
Plug in (x,y) = (7,35) to get the equation 35 = k*7
Dividing both sides by 7 leads to k = 5
Therefore, the direct variation equation is y = 5x
We can check this by plugging in x = 7
y = 5x
y = 5*7
y = 35
So x = 7 leads to y = 35 as expected.
-------------
Do the same for x = 4
y = 5x
y = 5*4
y = 20 when x = 4
Side note: direct variation equations always go through the origin.
Answer:
20
Step-by-step explanation:
if y varies directly with x, then it takes the form y=mx
to find m, substitute in the values of x and y to get 35=m*7 and simplify to get that m=5
then the equation becomes y=5x
substitute in the value they gave for x which is 4 to get y=5*4
to get that y=20
