Answer:Bb 12. Cyborg 12
Step-by-step explanation:
Right for my test
The required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.
Given that,
At a bargain store beast boy bought 5 items that each cost the same amount. Cyborg bought 8 items that each cost the same amount, but each was $1.50 less than the items beast boy bought. Both beast boy and Cyborg paid the same amount of money.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Let the cost of the item bought by the beast boy is x, and the item bought by the Cyborg be y,
According to the question,
5x = 8y
x = 8/5y - - - - - - -(1)
y = x - 1.50 - - - - - -(2)
Substitute the value of equation 1 to equation 2
y = 8/5y - 1.50
5y = 8y - 7.50
7.50 = 3y
y = 2.5
Now, put y in equation 1
x = 8 / 5 × 2.5
x = 8 × 0.5
x = 4
Now, the costs,
5x = 4 × 5 = $20
8y = 8 × 2.5 = $20
Thus, the required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.

Answer:
are you Philippines ty points
Answer:
a₂₁ = 41
Step-by-step explanation:
The nth term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = a₂ - a₁ = 3 - 1 = 2 , then
a₂₁ = 1 + (20 × 2) = 1 + 40 = 41
Find the midpoint of the segment with the given endpoints.
(-10,- 6) and (-3,7)
Step-by-step explanation:
in essence, these 2 points are the Hypotenuse of a right-angled triangle. the legs are the coordinate differences between the 2 points creating the 3rd point of that triangle at (-10, 7) : the x coordinate of one point, and the y coordinate of the other.
now, we are looking for the midpoint. this midpoint cuts the original line/hypotenuse in half creating a scaling factor of 1/2.
when we create now a similar triangle based on that "half- Hypotenuse", we need to use the same scaling factor also on the legs (the coordinate differences).
so, when we cut the coordinate differences also in half, we get the coordinates for the midpoint on the main line.
xm, ym are the coordinates of the midpoint.
xm = (x1 + x2)/2 = (-10-3)/2 = -13/2 = -6.5
ym = (y1 + y2)/2 = (-6+7)/2 = 1/2 = 0.5
so, the midpoint is (-6.5, 0.5)
Simplify the expression.

hannah and mallory are selling boxes of cookies for a school fundraiser. each box costs the same amount. hannah sells 14 boxes. mallory sells 22 boxes. mallory's neighbor makes a $6 donation without buying any cookies. together, hannah and mallory raise $141. write ans solve an equation to find out how much each box of cookies costs. how much does hannah raise? how much does mallory raise?
The cost per box of cookies is $3.75
The total amount Hannah raised from the sales of cookies is $52.50
The total amount Mallory raised from the sales of cookies and donations is $88.50
In order to determine the cost per box of cookies, take the following steps:
The first step is to determine the total sum of the boxes sold by Hannah and Mallory
Sum of the boxes sold = 14 + 22 = 36 boxes
36 boxes were sold by Hannah and Mallory
The second step is to determine the total cost of the 36 boxes sold.
Total cost of 36 boxes = total amount raised - donation
$141 - $6 = $135
The third step is to determine the total cost of each box
cost of one box = total cost of 36 boxes / total number of boxes
135 / 36 = $3.75
The total amount Hannah raised = cost per box x number of boxes she sold
14 x $3.75 = $52.50
The total amount Mallory raised = amount raised from the sale of cookies + donation
amount raised from sales = cost per box x number of boxes she sold
22 x $3.75 = $82.50
Total amount = $82.50 + $6 = $88.50

What's the domain of this function graph
Answer:
D) [0, ~)
Step-by-step explanation:
Domain of a Function:
the domain of a function is the set of values of x, the independent variable, that are responsible for the graph of the function.
For Example:
suppose, we have a function:
f(x) = 3x - 1
and it's domain is {1, 2, 3}
that means, the corresponding value of f(x) to these 3 values of x will be DEFINED, I.e., they exist and can be plotted on a graph.
The given function:
Therefore, for the given function, it's domain will be those values of x(the ones plotted on the horizontal line), that give some value to the function ,i.e., for which we can draw it's graph.
and since the graph starts from x = 0 and continues towards infiinity
(the arrow on the curve shows that the graph continues and hasn't yet come to a stop.)
So, that way we got [0, ~). ^^

Plug in -3 for f(x) into the first equation.
-3 = x^2 - 5x + 3
x^2 - 5x + 6 = 0
Factor!
(x - 3)(x - 2) = 0
Set each binomial equal to 0 to get the x-value of the point.
x = 3
x = 2
Plug each x-value back into the first equation (the answer should be -3, though it's always good to check) to get the y-value.
(3)^2 - 5(3) + 3
9 - 15 + 3
-6 + 3
-3
(2)^2 - 5(2) + 3
4 - 10 + 3

O(1,-5)
O (5,7)
O (7,5)
The coordinates of the image point will be P''(7, 5).
What is the difference between upward, downward, leftwards and rightwards translation?Upward translation {k units} : When the upward translation take's place then, each point will have its y - coordinate shifted upwards by +k units.Downward translation {k units} : When the downward translation will take place then, each point will have its y - coordinate shifted downwards by -k units.Leftward translation {k units} : When the leftward translation will take place then, each point will have its x - coordinate shifted by -k units to the left.Rightward translation {k units} : When the rightward translation will take place then, each point will have its x - coordinate shifted by +k units to the rightGiven is to translate P(4, 0) right by 3 units and up by 5 units.
Rightward translation : P'(4 + 3, 0 + 0) = P'(7, 0)
Upward translation : P''(7 + 0, 0 + 5) = P''(7, 5)
Therefore, the coordinates of the image point will be P''(7, 5).

The correlation coefficient for the costs and sizes of storage container is 0.55. How
are the costs and sizes of the containers related?
Answer:
There is a positive correlation between both variables.
Step-by-step explanation: That is to say, the relation between the cost and the size of the storage containers is growing.
As the size of the container increases the cost also increases.
The closer the correlation coefficient is to 1, the stronger is the positive relationship between the variables, in this case r = 0.52, so it could be concluded that the relationship between the variables is a medium positive correlation
A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.
The costs and sizes of the containers are moderately correlated.
What is a correlation coefficient?A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.
We have,
The correlation coefficient for the costs and sizes of the storage container is 0.55.
We know that,
Correlation coefficients whose magnitude is between 0.5 and 0.7 indicate that the variables are moderately correlated.
Correlation coefficients whose magnitude is between 0.3 and 0.5 indicate that the variables are a low correlation.
Since the correlation coefficient for the costs and sizes of the storage container is 0.55, it is between 0.5 and 0.7.
So it is moderately correlated.
Thus the costs and sizes of the containers are moderately correlated.
