is this a domain or range?
please help :(
Step-by-step explanation:
it's a function.
the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
the domain is (1,3,7,8)
the range is (2,4,6,9)
The ratio of males to females at a party is 3 : 5
There are 12 more females than males.
How many people are at the party?
Answer:
48
Step-by-step explanation:
Given ratio of males to females at a party is 3 : 5.
Let the numbers of males and females be 3x and 5x respectively.
According to the given description:
No of females = No of males + 13
Therefore,
5x = 3x + 12
5x - 3x = 12
2x = 12
x = 12/2
x = 6
No of people at the party
= 3x + 5x
= 8x
= 8*6
= 48

Two pieces of ribbon, one with a length of 63 inches and another with a length of 42 inches are cut into pieces of equal length without remainder. Find the greatest possible length that the pieces can be.
Answer
224 over 567
Step-by-step explanation:
Answer:
21
Step-by-step explanation:
the greatest possible length that the two ribbons would be when the ribbons are divided by their lowest common multiple.
The lowest common multiple of 63 is 3. 63/3 = 21
The lowest common multiple of 42 is 2 = 42/2 = 21

Step-by-step explanation:
Answer:
32x+20
Step-by-step explanation:
If you use distributive property you would multiply each number by 4. 4 times 8x is 32x and 4 times 5 is 20, and when you put those together you get 32x+20!

Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.

Answer: The answer is 0.20
Step-by-step explanation: To find a scale factor all you need to do is find the ratio of a side on the scaled shape to its corresponding side on the original figure. We know the bottom of the scaled figure is 0.5 and the same side on the original rectangle was 2.5 so we can just divide like so...
0.5/2.5 = 0.2 which is our correct answer. I hope this has been of use to you :) If you have any other questions please do not hesitate to ask!

Step-by-step explanation:
Basically to find the slope you take the rise over run. How many squares does the line go up, over how many does it go left or right. As you can see in the diagram, it goes up 2 squares and goes left 1 square, giving the slope 2/1, which is 2.
The slope of a horizontal line is straight, which means it goes up 0, so automatically your answer is zero, because dividing anything by 0 is 0.

3. A computer is priced at $65,000 plus value added tax at 15%. What amount does the computer actually cost the customer?
Answer:
$74,750
Step-by-step explanation:
Given that,
The cost of a computer = $65,000 + value added tax at 15%
We need to find the amount the computer actually cost the customer.
Total cost = Cost of computer + VAT at 15%
[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]
So, the computer actually cost the customer is $74,750.
If the triangles are similar, find the value of x.
Answer:
x=25Step-by-step explanation:
the triangles are similar
so as we know
when two triangles are similar the rotio of triangles is equalnow let's solve it
to understand the solving stepsyou need to know aboutequation with fractionPEMDASaccording to the question
[tex] \frac{24}{30 } = \frac{x + 7}{2x - 10} [/tex]
[tex] \frac{4}{5} = \frac{x + 7}{2x - 10} [/tex]
[tex]4(2x - 10) = 5(x + 7) \: (cross \: multiplication)[/tex]
[tex]8x - 40 = 5x + 35[/tex]
[tex]8x - 5x = 35 + 40[/tex]
[tex]3x = 75[/tex]
[tex]x = 25[/tex]

Find the slope of the line from a graph! Will Give brainliest :)
Answer:
-4
Step-by-step explanation:
because the line is going from top to bottom it is negative
you take the rise ( the Y value) / the run (the X Value)
the Y and X value can be pulled from any two points
The sum of two numbers is 10. Their difference is 6. What are the two numbers?
Answer: 8 and 2
Step-by-step explanation:
this is simple, since we only have 10 numbers to work with. i just kept experimenting with numbers until i got one that had a difference of 6. no strategy, just brain power. hope this helps! xoxo
Answer:
So negatove numbers are gonna be impossible becuase we know that the highest we can go is -10+20=10 but it’ll give a whole different difference when subtracted.
And it can’t be greater then 10 becuase if you do add them it won’t be 10
SO it has to be between 1-10
So what equals 10?
5/5
2/8
8/2
6/4
4/6
3/7
7/3
Now 5 and 5 is out cause if subtracted its 0
2/8 and 8/2 works, if added you get 10 but when subtracked the way for 8/2 from left to write it’ll give 6 which is the only one which will give.
final answer the two numbers are 8 and 2
what is the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1)?
Answer: The other point is (17, -6).
Step-by-step explanation:
Midpoint (x,y) of the line segment joining (a,b) and (c,d) is given by :-
[tex](x,y) =(\dfrac{a+c}{2}, \dfrac{b+d}{2})[/tex]
Here, we need to find the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1).
Let other point be (a,b), then
[tex](7,1)=(\dfrac{-3+a}{2},\dfrac{8+b}{2})\\\\\Rightarrow\ \dfrac{-3+a}{2}=7\ \text{ and }\dfrac{8+b}{2}=1\\\\\Rightarrow\ -3+a = 7\times2 \text{ and } 8+b=1\times2\\\\\Rightarrow\ -3+a=14\text{ and }8+b=2\\\\\Rightarrow\ a=14+3, \ \ \ b= 2-8\\\\\Rightarrow\ a=17, b= -6[/tex]
hence, the other point is (17, -6).

Can the sides of a triangle have lengths 3, 7, and 15?
1/10( x + 130) = -2(3-X)
I need help
Answer:
x = 10
Step-by-step explanation:
1/10(x + 130) = -2(3 - x)
x + 130 = -20(3-x)
x + 130 = -60 + 20x
x - 20x = -60 - 130
-19x = -190
x = 10
