Find the greatest common factor between 18 and 60? Help me or I die.....Jk help me plz
Step-by-step explanation:
I dont know the answer exactly but to find the greatest common factor you have to find out like the numbers that go into the timetable your talking about like e.g a factor of 18 would be 6,3,2 etc. once you have done that between both of them then you have to find the same numbers between them. and that's the answer. hope it helped I'm not exactly good at explaining

let f(x)= p+ 8/x-q. the line x=4 is a vertical asymptote to the graph of f. what is the value of q and p, if the y intercept is (0,4)?
Answer:
The value of q and p is 4 and -24 respectively.
Step-by-step explanation:
Being [tex]f(x)=\frac{p+8}{x-q}[/tex] , the line x=4 is a vertical asymptote to the graph of f(x). The line r is an asymptote of a function if the graph of the function is infinitely close to the line r. That is, an asymptote is a line to which a function approaches indefinitely, without ever touching it.
Being a rational function that which can be expressed as the quotient of two polynomials, a vertical asymptote occurs when the denominator is 0, that is, where the function is not defined. In this case:
x - q= 0
Solving:
x= q
Being the line x=4 the vertical asymptote, then
4=q
Then the function f (x) is:
[tex]f(x)=y=\frac{p+8}{x-4}[/tex]
The y intercept is (0,4). This is, x= 0 and y=4. Replacing:
[tex]4=\frac{p+8}{0-4}[/tex]
Solving:
[tex]4=\frac{p+8}{-4}[/tex]
4*(-4)= p+8
-16= p+8
-16 - 8= p
-24= p
The value of q and p is 4 and -24 respectively.
A car travels at a constant speed, as shown on the double number line. Double number line. Time, hours. Distance, kilometers. How far does the car travel in 14 hours? Explain or show your reasoning.
Answer:
980 km.
Step-by-step explanation:
The speed of the car is constant,
From the double number line:
When the time is 0 hour, the distance covered is 0 km.
When the time is 1 hour, the distance covered is 70 km.
When the time is 2 hours, the distance covered is 140 km,
which can be written as
when the time is 2 hours, the distance covered is 70 x 2 km.
Similarly,
When the time is 3 hours, the distance covered is 210= 70 x 3 km.
This can be generalized as,
When the time is n hours, the distance covered is 70 x n km, i.e
The distance traveled in n hours = 70 x n km.
So, for 14 hours, n= 14,
Hence, the distance traveled in 14 hours = 70 x 14= 980 km.
the endpoint of ab are a(-7, -6) and b(5,6) what are the coordinates of point c on ab that is 1/3 the distance from point a to point b
Answer:
The coordinates of c are (-3,-2)
Step-by-step explanation:
We have the coordinates of a=(-7,-6) and b=(5,6). We need to find the coordinates of a point c=(x,y) such that:
[tex]d_{ac}=1/3 d_{ab}[/tex]
The coordinates x and y have the same relation as the distance:
[tex]x_{ac}=1/3x_{ab}[/tex]
Or, equivalently:
[tex]x_a-x=\frac{1}{3}(x_a-x_b)[/tex]
Multiplying by 3:
[tex]3x_a-3x=x_a-x_b[/tex]
Operating:
[tex]3x_a-x_a+x_b=3x[/tex]
[tex]2x_a+x_b=3x[/tex]
Dividing by 3:
[tex]x=\frac{2x_a+x_b}{3}[/tex]
Similarly:
[tex]y=\frac{2y_a+y_b}{3}[/tex]
Substituting:
[tex]x=\frac{2*(-7)+5}{3}=-3[/tex]
[tex]y=\frac{2*(-6)+6}{3}=-2[/tex]
The coordinates of c are (-3,-2)

Shannon paid $57.25 for 28 pounds of potatoes. Shannon estimated the cost per pound to be $3.00. What is her error?
Answer:
She rounded her estimation up.
Step-by-step explanation:
Shannon paid $57.25 for 28 pounds ($57.25÷28=2.0446428571)
If you round the answer to the nearest dollar, you'll look at the number in the tenths place (0). Zero is not 5 or greater. That makes the 2 stay the same.

Jeff has two sticker-printing machines. Each machine can print 42 stickers per minute. On day 1, only the first machine was used, and it printed 89 stickers. On the following day, the first machine printed for x minutes and the second machine printed for y minutes. Which expression shows the total number of stickers printed by both machines during these two days? (1 point) a 131x + 42y b 42 + 89x + y c 89 + 42x + 42y d 89x + 84y
Answer:
c 89+42x+42y
Step-by-step explanation:
On day 1 :
First Machine= 89 stickers
Second Machine= none
On day 2 :
First Machine= ? stickers ( if in 1min = 42stickers
x min=?
( x min/1 min × 42stickers)
=42x stickers.
Second Machine=?stickers ( if in 1min = 42stickers
y min=?
( y min/1 min × 42stickers)
=42y stickers.
Total = 89 + 42x + 42y
A biologist begins working with a sample containing 20,000 bacteria. The population size doubles every 10 days according to the equation p(t)=20,000(2)^t/10, where t represents the number of days. After seven days the biologist begins working with a second sample of 20,000 bacteria. The equation used to represent the population of sample 2 after t days is p(t)=20,000(2)^t-7/10. Which of the following is an equivalent form of the equation for the population of sample 2?

The perimeter of a flower garden with three sides is 46 feet. One side of the garden is 11 feet long. Another side of the garden is 13 feet long. What is the length of the third side? Enter your answer in the box. feet
Answer:
22ftStep-by-step explanation:
Step one:
given that the orientation of the garden is a triangular shape(it has three sides)
the perimeter is given as=46ft
one side y=11ft
the second side z= 13ft
let the third side be xft
Step two:
the expression for the perimeter = z+y+x
46=11+13+x
46=24+x
solve for x
x=46-24
x=22ft
Therefore the third side is 22ft long

which of these equations represents a line parallel to the graph of the equatioN
y=-1/3x-5
Answer:
[tex]y=-\frac{1}{3}x\pm c[/tex]
Step-by-step explanation:
The equation of two parallel lines is such that they have the same slope, when in written in slope intercept form.
Consider one straight line: [tex]y_{1}=mx_{1}+c_{1}[/tex].
Then the line parallel to the above line will be:[tex]y_{2}=mx_{2}+c_{2}[/tex]
The equation of a straight line provided is:
[tex]y=-\frac{1}{3}x-5[/tex]
Then the line parallel to this line will be of the form:
[tex]y=-\frac{1}{3}x\pm c[/tex]

d. The Pup Palace Kennel is never cheaper than Ngyuen's Kennel
Step-by-step explanation:
PLS HELP WITH THE QUESTION IN THE PICTURE!!!
Answer:
D
Step-by-step explanation:
Interesting question. The wording is a bit awkward. I think you have to assume the base is a square and each succeeding base is also a square.
So the first thing to do is to add the bases together.
30*30 + 23*23 + 16*16 + 9*9
Don't add these -- not yet.
Now take the height into consideration
6 *(30*30 + 23*23 + 16*16 + 9*9)
The point is that you only have to multiply by 6 once.
6*(900 + 529 + 256 + 81)
6*(1766)
10596 cubic inches
