the waiters at a restaurant have agreed to give one third of their tips to the kitchen staff if a waiter collects 72$ how much does he end up keeping
Answer:
48
Since they are giving one third of it to the staff, they are keeping 2 thirds of it for themselves. Two thirds of 72 is 48.
Answer:
He keeps $48.
Step-by-step explanation:
If he gives away 1/3, he keeps 2/3 so that's what we need to calculate.
First find 1/3 of 72 by dividing by 3: 72/3=24
Now to find 2/3, multiply by 2: 24*2=48
(72/3)*2= $48
Find the length and width of a rectangle sandbox, where the length is 3 feet longer than it’s width if you are building it with 22 feet of lumber
Let the length be represented by l and the width, w.
The question says that the length is 3 feet longer than the width. This means that
[tex]l=w+3[/tex]The perimeter of a rectangle is given as
[tex]2(w+l)=P[/tex]The perimeter of the sandbox is given as 22 feet.
Substituting the values for the perimeter and the length (w + 3) into the perimeter formula, we have
[tex]2(w+w+3)=22[/tex]Solving, we have
[tex]\begin{gathered} 2(2w+3)=22 \\ 2w+3=\frac{22}{2} \\ 2w=11-3 \\ 2w=8 \\ w=\frac{8}{2} \\ w=4 \end{gathered}[/tex]Now that we have the value for the width, we can calculate the length as
[tex]\begin{gathered} l=w+3 \\ l=4+3 \\ l=7 \end{gathered}[/tex]The length is 7 feet and the width is 4 feet.

The property that completes the proof is the segment addition postulate
How to determine the statement that represents the reason in the proof?The given parameters in the question are:
The point C is the midpoint of AE
BC = CD
The above implies that
AC = CE
And it also means that:
The line segment BC and the line segment CD have equal lengths
Using the above as a guide, we have the following equations
AB + BC = AC
CD + DE = CE
The above equations are true because of the segment addition postulate
This postulate states that:
For any two points (A and C) located on a line segment and a third point (b) between the initial points. The lengths between the points can be represented as AB + BC = AC
Hence, the statement that represents the reason 3 in the proof is (b) segment addition postulate

Deluxe coffee is to be mixed with regular coffee to make at
least 43 pounds of a blended coffee. The mixture must
contain at least 12 pounds of deluxe coffee. Deluxe coffee
costs $6 per pound and regular coffee $5 per pound. How
many pounds of each kind of coffee should be used to
minimize costs?
Answer:
12 pounds of deluxe and 31 pounds of regular.
Step-by-step explanation:
$227 is the minimum cost.
Answer:
We have to minimize the cost of 51 pounds of blended coffee.
The mixture must contain 13 pounds of deluxe coffee.
Deluxe coffee costs $4 per pound while regular coffee costs $3 for the same amount.
So, we need to maximize the concentration of regular coffee in the blended coffee to minimize our costs, but we must mix 13 pounds of deluxe coffee in order to make the blended coffee as it is the condition given to us in the problem.
Hence, apart from this 13 pounds, all the rest weight in blended coffee should come from the regular one.
Hence, the amount of regular coffee we have to use = (51 - 13) = 38 pounds.
Now, the cost of the 51 pounds of blended coffee
38×3+13×4 = ₹166.

You make an investment of $2250.00 with an absolute change of ―$350.00. What is your investment now
worth and what was the percent change?
1. The investment of $2,250 with an absolute change of -$350 is now worth $1,900.
2. The percentage change in the worth of the investment is -15.56%.
What is a percentage change?A percentage change refers to the percentage difference between the initial value and the current value.
To compute the percentage change, use the absolute change and divide by the initial value, then multiply by 100.
For this investment of $2,250 which is now worth $1,900, there was a percentage change of -15.56%, implying that it has drastically reduced in value.
Initial Investment Cost = $2,250.00
Absolute change in investment value = $350
Current value of investment = $1,900 ($2,250 + $350)
The percentage change = -15.56% (-$350/$2,250 x 100)
Thus, the investment is currently valued at $1,900, having lost $350 in value, which in percentage terms, is -15.56%.

Blank 1:
The an equation (slope-intercept form) of the line is 2y = 5x + 108.
What is described as the slope-intercept form?A line's equation can be written in a variety of ways, each of which is valid. The slope-intercept form of such a line is a way of writing a line's equation so that the slope and y-intercept are easily recognizable. The slope of the line is its steepness, and the y-intercept is the point where line intersects the y-axis.For the given question;
The equation of the perpendicular line is given as 2x + 5y = 10.
The passing points of the line (-20, 4)
(x₁, y₁) = (-20, 4)
The equation of line in slope-intercept form is given as; y = mx + c.
Where, c is the y intercept and m is the slope.
The relation of the slope of two perpendicular lines are-
m₁ x m₂ = -1
The equation of line is-
2x + 5y = 10; find m₁
5y = -2x + 10
y = (-2/5)x + 10
Comparing with standard form.
m₁ = (-2/5)
Then, m₁ x m₂ = -1
(-2/5) x m₂ = -1
m₂ = 5/2
Put in the equation of line;
y - y₁ = m(x - x₁)
Put the values;
y - 4 = (5/2) (x + 20)
Solving;
2y - 8 = 5x + 100
2y = 5x + 108
Thus, the an equation (slope-intercept form) of the line is 2y = 5x + 108.

Based on the domain, the equation of the function f(x) is F(x - h) = x^2 - 2xh + h^2 + 2
What is the domain of a function?The domain of the function is the set of input values of the graph
How to determine the solution of the function f(x)?The equation of the function is given as
F(x) = x^2 + 2
The required function is given as
F(x - h)
The above means that the value of x in the function F(x) = x^2 + 2 is x - h
i.e.
x = x - h
So, we substitute x - h for x in the equation F(x) = x^2 + 2
This gives
F(x - h) = (x - h)^2 + 2
Evaluate the exponent
So, we have
F(x - h) = x^2 - 2xh + h^2 + 2
The above equation cannot be further simplified
Hence, the solution of the function f(x) at the given domain is F(x - h) = x^2 - 2xh + h^2 + 2

A linear relationship is shown in the graph.
Which equation best represents the relationship between x and y?
(A) The equation y = ( 1/4 )x + 2 best represents the relationship between x and y.
From the graph, we can see that the line is passing through points ( - 8, 0 ) and ( 0, 2 ).
So, to obtain the equation that represents the best relationship we will substitute the points in the equation to check whether they satisfy or not.
Consider option (a),
y = ( 1/4 )x + 2
For ( - 8, 0) :
0 = ( 1/4 ) × - 8 + 2
0 = - 2 + 2
0 = 0
For ( 0, 2 ):
y = ( 1/4 )x + 2
2 = (1/4) × 0 + 2
2 = 2
Hence, the equation y = ( 1/4 )x + 2 passes through both points.
Consider option (b),
y = 4x - 8
For point ( - 8, 0 )
y = 4(-8) - 8
y = - 32 - 8 = - 40 ≠ 0
For point ( 0, 2)
y = 4(0) - 8 = - 8 ≠ 2
Hence, the equation y = 4x - 8 does not pass through the points.
Consider option (c),
y = ( 1/4 )x - 8
For ( - 8, 0 )
y = ( 1/4 ) × - 8 - 8
y = - 2 - 8 = - 10 ≠ 0
For ( 0, 2)
y = ( 1/4 ) × 0 - 8 = - 8 ≠ 2
Hence, the equation y = ( 1/4 )x - 8 does not pass through points.
Consider option (d),
y = 4x + 2
For point ( - 8, 0 )
y = 4( - 8) + 2
y = - 32 + 2 = - 30 ≠ 0
For point ( 0, 2)
y = 4( 0 ) + 2 = 2
2 = 2
Hence, the equation passes through ( 0, 2) but does not pass through the point ( - 8, 0 ).
Therefore, the equation that represents the relationship between x and y is y = ( 1/4 )x + 2
