Answer:
5 hours
Step-by-step explanation:
The problem is giving you the equation
y = 0.4x; where y is the # of buckets filled and x is the hours.
If they you 2 filled buckets, then how many hours?
You need to solve for x
y = 0.4x; to get the x by itself, divide by 0.4
x = [tex]\frac{y}{0.4}[/tex] ; now substitute y with 2 ( for 2 filled buckets)
x = [tex]\frac{2}{0.4}[/tex] = 5; which means it took 5 hours to fill up 2 buckets.
{8x + 9y = −3 ,6x + 7y = 1 What values of x and y satisfy the system of equations
Answer:
The value of x=−15 and y=13
The Comfy blanket is regularly priced at $39.99 online on amazon. The website is offering a 10% discount as part of their holiday sales. There is a 6% tax as well. Find the find the final cost.
Answer:
$38.4Step-by-step explanation:
Step one:
we are told that the price online is $39.99
and that the discount is 10%
and also tax is 6%
Step two:
discount
let us solve for the deduction first
=10/100*39.99
=$3.99
Tax
=6/100*39.99
=$2.4
The final cost= cost online-10% discount+6% tax
Final cost= 39.99-3.99+2.4
Final cost = $38.4

Evan told his mom that he could make 14/ 12 of a cake and 5/ 6 of another cake into 2 whole cakes his mom said no way prove it explain why or why not
Answer:
The mother is wrong
Step-by-step explanation:
What we do here will be to add the fractions of the cakes that we have
Mathematically, that will be;
14/12 + 5/6 = 24/12 = 2
This means that the mother is wrong and the cakes can actually be made into 2

5/7 = a/35 what is the answer ?
Answer:
hello! I am pretty sure the missing number is 25!
Step-by-step explanation:
Here is why I think so, I believe that because it seems to me that you are multiplying 7 by 5 so I think that you should multiply 5 by 5 and if you do that it is 25. Hope this helps!
Why does the sequence of translating and reflections matter?
Answer:
If two or more of the transformations have a vertical effect on the graph, the order of those transformations will most likely affect the graph. If two or more of the transformations have a horizontal effect on the graph, the order of those transformations will most likely affect the graph.

Step-by-step explanation:
Using the slope, state whether the lines are parallel, perpendicular, or neither.
Y= 2x-3
y=-1/2x+2
Answer:
Parralel lines have the exact same slope.
in the equation y=mx+b m is the slope
Both of these equations are in slope intercept form (y=mx+b) meaning that the coefficient in both equations is the slope.
Parralel lines have the same slope and perpendicular lines have the inverse opposite slope. For example if a line had a slope of 2 or 2/1 then the perpendicular line to it would have a slope of -1/2.
With that knowledge we can easily see that the lines are perpendicular since their slopes (represented by the coefficient) are the inverse opposite.
Perpendicular is your answer

What is the value of n of this data? Type a numerical answer in the space provided. Do not type spaces or decimals in your answer.
3, 12, 15, 25, 30, 40
Answer:
The value of n for this data is 6
Step-by-step explanation:
The given data is:
3, 12, 15, 25, 30, 40
In a set of given data, n is used to represent the number of values in a dataset. The values are also called observations. Hence, the total number of observations in a dataset are denoted by n.
In the given dataset, total values are 6.
So,
n = 6
Hence,
The value of n for this data is 6

Answer:
1. Number 1 and 2 and 4 is a function, 2. number 1 is a function
Step-by-step explanation:
1)To know if it's a function or not run vertical lines through multiple places of the graph. If it is a function every single time you do the vertical line test it should only go over the line once. If you do the vertical line test on 3 you will see that it went over the line on the graph, so we know not a function. Graphs 1, 2, and 4m however, are different, when you do the vertical line test on those graphs it only goes over them once.
2) Choice (1) is a function because when drawing vertical lines through the graph it only goes over one.
Choice (2) is not a function because when drawing vertical lines through the graph it covers two points on the graph.
Choice (3) is not a function because when drawing vertical lines through the graph it goes over multiple points.
Choice (4) is not a function because when a vertical line is drawn, it goes over more than one point on the graph.
The vertical test is a way to determine if it is a function.
When looking at a table functions are one-to-one and many-to-one
Non-functions are one-to-many and many-to-many

Which of these inequalities are equivalent to r > -11? Check all that apply.
-r -33
-3r 33
Answer:
the first choice, the third, and the fourth
The inequality which is equal to r>-11 is -3r<33.
What is inequality?Inequality is like an equation but it is expressed in greater than ,less than ,greater than or equal to and less than or equal to form. It also shows a relationship between two or more variables. We can also change sign by putting negative sign in both sides of the sign.
How to find inequality?We have been given inequality as r>-11 and we have to find the appropriate equivalent inequality from the given options.
We can find the inequality by multiplying and changing sign by putting negative sign on both sides of sign.
r>-11
Multiply both sides by 3
3*r>-11*3
3r>-33
Change > sign to < sign.
-3r<-(-33)
-3r<33
Hence the inequality which is equal to r>-11 is -3r<33.
