Answer:
The 15% discount means that they only pay 100%-15% = 85% of the meal's bill.
This would cost 85% * 78.65.
However, they also have to pay a 20% tip of the meal cost.
This would cost 20% * 78.65.
Step-by-step explanation:
total Cost = (85% * 78.65) + (20% * 78.65)
= 105% * 78.65
= 1.05 * 78.65
= $82.58
cylinder a has a radius of 10 inches and a height of 5 inches. cylinder b has a volume of 750π. what is the percentage change in volume from cylinder a to cylinder b?
There is 50% increase in the change in the volume of cylinder A to A
The formula for the volume of the cylinder is given as
V = Πr^2h (1)
Where, r = radius of the cylinder
h = height of the cylinder
We have been given the radius and height of cylinder A which are,
r = 10 inches
h = 5 inches
Now putting the required values in equation (1) we get
V = Π(10)^2(5) cubic inches
V = Π*100*5 cubic inches
V = 500Π cubic inches
We have also been given the volume of cylinder B = 750Π
Thus percentage change in volume of cylinder = (750Π - 500Π)/500Π * 100
= 50%
Hence there is 50% increase in the change of the volume from cylinder A to B

If the function is reflected across the y-axis of the graph of f, the resulting function will be g(x) = 4x + 1
Translation of functionsTranslation is the technique that is used to change the position of a figure on an xy-plane.
For instance, if the function f(x) is reflected in the y-axis, the resulting function will be g(x) = f(-x)
Given the function f(x) = -4x+1 if the function is reflected in the y-axis of the graph of f.f, the resulting function will be;

The scale on the horizontal axis is 5 s per division and on the vertical axis 9 m per division. What is the time represented by the third tic mark on the horizontal axis? Answer in units of s.
Using proportions, it is found that:
The time represented by the third tic mark on the horizontal axis is of 15 seconds.The position represented by the fourth tic mark on the vertical axis is of 36 meters.The position at t = 15s is of 18 m.What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
On the horizontal axis, each tic represents 5 seconds, hence:

5. Charnita Jones earns $304.80 per week as a sales assistant. Next week she will be
promoted to assistant manager. She will then earn $332.50 per week. She is single
and claims 1 allowance. How much more will she pay in federal income tax?
Charnita Jones will have to pay $5 more in federal income tax.
According to the question we have been given that Charnita Jones
As sales assistant she earned = $304.80
After promotion as assistant manager she will earn = $332.50
Number of allowance she claims = 1
We need to find how much more she will pay in federal income tax.
For that we will first calculate how much she paid when her earning was $304.80. For this we will use the table for single persons-weekly payroll period. In that table, first we will choose the row of wages from the column number 1. We look to that row where $304.80 will lie that is the row will be $300-$310. then we will look for allowance that is 1. Thus the tax she will pay will be in column of allowance 1 and in the row of $300-$310 is $22.
In similar way we will find out the tax she will pay when she earn $332.50 which is $27.
Difference = $27 - $22 = $5
Hence she will have to pay $5 more in federal income tax.

What do you mean by the unitary method?The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
As a result, multiplying by 2, the man travels 3.5 miles in one hour.
The distance the man walks in 7 hours, multiplied by 7, comes out to be 24.5 miles. Alternatively, you might divide the man's distance traveled by 7, or X, to get 7 (x/7). It equals the time needed to travel X miles, which is 2 hours (7/2), divided by the time needed to go X miles, which is 7 hours. X, therefore, equals 24.5 miles.

a) y=-x+5
b) y=-x-2
c) y= 4x + 2
d) y=-4x-4
Answer: Any line with slope of -3/4
Reason:
Let's calculate the slope of the line through those two points
[tex](x_1,y_1) = (1,3) \text{ and } (x_2,y_2) = (4,7)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{7 - 3}{4 - 1}\\\\m = \frac{4}{3}\\\\[/tex]
The slope of the line is 4/3
Anything perpendicular to this has a slope of -3/4. I flipped the fraction and flipped the sign (from positive to negative).
So for example, the answer may be something like [tex]y = -\frac{3}{4}x+5[/tex] or [tex]y = -\frac{3}{4}x-2[/tex]. All that matters is the -3/4 out front of the x.
Side note: the original slope 4/3 and perpendicular slope -3/4 multiply to -1

An airplane leaves Los Angeles and travels 5 hours to New York City. The return trip travels along the same route and takes 6 hours because the plane travels 99 mph slower due to a headwind. Find the distance the plane flies between the two cities.
Using the relation between velocity, distance and time, the distance of the plane ride between Los Angeles and New York is of 270 miles.
What is the relation between velocity, distance and time?Velocity is distance divided by time, hence the following equation is built to model the relationship between these variables:
v = d/t.
For the Los Angeles to New York trip, we have that the time is of 5 hours, hence:
v = d/5.
v = 0.2d.
For the return trip, we have that the time is of 6 hours, while the velocity is 99 mph slower, hence:
v - 99 = d/6.
From the first equation, we have that:
v = 0.2d.
Replacing on the second:
0.2d - 99 = d/6.
d(0.2 + 1/6) = 99
0.3667d = 99
d = 99/0.3667
d = 270 miles.
The distance of the plane ride is of 270 miles.
