Using proportions, it is found that the weekly amounts are given as follows:
Federal Withholding: $33Social Security Tax: $22.51.Medicare Tax: $10.53.State income tax: $134.31.What is the missing information?We have to determine for Lucretia these following weekly amounts:
Federal Withholding.Social Security Tax.Medicare Tax.State income tax.The rates are given as follows:
Withholding allowance: $33 (for someone earning $363 a week).Medicare tax: 2.9%.Social Security: 6.2%.State tax: 37%, as she lives on a state with no tax, hence pays only the Federal rate.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.
Lucretia's weekly salary is given as follows:
20 x 18.15 = $363.
The withholding allowance is fixed at $33 for a person earning her amount, while the tax rate is of 37%, as she lives in a state with no income tax, hence she only pays the federal tax rate.
The other amounts are given as follows:
Medicare Tax: 0.029 x 363 = $10.53.Social Security Tax: 0.062 x 363 = $22.51.State tax: 0.37 x 363 = $134.31.More can be learned about proportions at https://brainly.com/question/24372153

From the given absolute value function, we have that:
The cyclist starts 20 kilometers from the station.The cyclist reaches the station in 60 minutes.What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin.
For this problem, the function is:
d(t) = 1/3|t - 60|.
The d-intercept is given by:
d(0) = 1/3|-60| = 20.
Hence: The cyclist starts 20 kilometers from the station.
The t-intercept is found as follows:
1/3|t - 60| = 0
t - 60 = 0
t = 60.

Scaling a Rectangle
A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
Scale factor back to original size = 1/7
The transform object is a mathematical mapping from one coordinate system to another. The coordinate system can differ in position (i.e. origin), scale, axis orientation, and relative axis orientation. We are told that the rectangle has been scaled by a factor of 7. This means that if the length and width are x and y respectively, the new scaled measurements will be;7x and 7 years.
Now, to get us back to the original size, all we have to do is divide the new scale measure by a factor of 7.This means the original size will be;
Length = 7x × 1/7
Width = 7y × 1/7
Hence, the scale factor will be 1/7 back to the original size.

Given the following values, find the perimeter of the figure shown below:
AB = 7 cm, BC = 3 cm, CD = 1 cm, DE = 2 cm, EF = 3 cm, and FG = 1 cm.
Do not include "cm" with your response.
Answer:
26
Step-by-step explanation:
First, split the figure into 3 rectangles and label the sides so that it is easier to work with.
Then you have to find the unknown values: HG and AH.
HG: Since AB=7 and AB is the longest horizontal side; we know that HG+EF+CD=AB=7. Plugging in the known values: HG+3+1=7 => HG+4=7. Therefore, HG=3 because 3+4=7.
AH: BC and FG are the corresponding sides to AH so AH+FG=BC. Plugging in the known values: AH+1=3. Therefore, AH is 2 because 2+1=3.
Now you have to use the perimeter of rectangle formula which is P=2(L+w) for the 3 rectangles.
Rectangle 1: 2(3+2)=10
Rectangle 2: 2(3+1)=8
Rectangle 3: 2(3+1)=8
Add them all up to find the total perimeter: 10+8+8=26.

If we are borrowing $10840 to buy a car and repaying it in 6 years (or 72 months) , our monthly payment will be $150.55 or rounded of $200.
As per the question statement, we are borrowing $10840 to buy a car and repaying it in 6 years (or 72 months) , what will be the estimate monthly payment by rounding off to the nearest hundred dollars
First we are supposed to find the monthly payment then we can round it off to the nearest hundred dollars.
Total loan borrowed = $10840
Time taken to pay it off = 6 years or 72 months,
Payment to be made per month = [tex]\frac{10840}{72} \\ 150.5556[/tex]
Therefore [tex]150.5556[/tex] dollars is to be paid every month for 72 months.

maths midpoint theorem
Step-by-step explanation:
10.
the various sides and line segments have been marked as equal already.
so, SSS proves that both triangles are congruent.
but to reprove things with the midpoint theorem :
remember
the line segment in a triangle connecting the midpoints of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.
so,
D, F are the midpoints of BA and BC.
so, AC is parallel to DF and twice as long as DF.
D, E are the midpoints of BA and AC.
so, BC is parallel to DE and twice as long as DE.
E, F are the midpoints of AC and BC.
so, BA is parallel to EF and twice as long as EF.
so, DF = AE = EC
DE = BF = FC
EF = BD = DA
so, the EF of DEF corresponds to DA of ADE.
DF corresponds to AE.
and DE is shared between both triangles.
so, again, all 3 sides correspond 1:1 to sides in the other triangle. and SSS proves they are congruent.
11.
equilateral means all 3 sides are equal :
PS = PT = ST
TSR can only be isoceles (both legs are equal) when
ST = SR
because PM = MQ, M is the midpoint of PQ.
and because of MS || QR, S is the midpoint of PR.
that means PS = SR.
and because PS = ST, ST = SR
therefore, TSR is isoceles.

meters. A bus requires 30 square meters. The attendant can handle only
60 vehicles. If a car is charged $2.50 and a bus $7.50, how many of each
should be accepted to maximize income?
The number of cars should be 100 and that of bus be 0.
x is the number of cars and y is the number of buses.
Area: 6x + 30y <= 600 simplifies to x + 5y <= 100
Total money collected: 2.50x + 7.50 y …..this is what you want to maximize
OR you want to maximize 2.50 (x+ 3 y)
OR you want to maximize (x+3y)
Replacing the value of x from the Area equation in the above price, we get
100 - 5y + 3y is the maximum amount you can collect
So you want to maximize 100 - 2y. This happens when y is 0.
When y is 0; x will be 100 and you will collect 250.

If initial deposit is GBP 3000 and the rate is 3.5%,then after 32 years it will reach to GBP 9000.
Given that the initial deposit is GBP 3000 and the rate is 3.5%.
We are required to find the number of years after which the amount will reach to GBP 9000.
Compound interest is basically the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.
Amount after compounding=P[tex](1+r)^{n}[/tex], where P is principal ,r is rate of interest and n is number of years.
The number of years can be calculated as under:

What is the equation of the tangent line of a curve at a given location?
A line is tangent to a function if and only if the function meets the curve only in one point. The slope of the tangent line can be found by using the first derivative of the curve and the y-intercept is determined from the slope-intercept form of the equation of the line. First, determine the slope of the tangent line:
f'(x) = 12 · x
f'(0) = 12 · 0

A truck driver is driving from Nome, Alaska to Death Valley, California. Because he is traveling between locations with extreme temperatures, he needs to check the weather continuously to make sure the gas in his truck remains in liquid form. The gas he uses freezes at −40° F and evaporates at 140° F.
Part A: Write an inequality to represent the temperatures at which the gas in the truck will remain in liquid form. (2 points)
Part B:Describe the graph of the inequality completely from Part A. Use terms such as open/closed circles and shading directions. Explain what the solutions to the inequality represent. (4 points)
Part C: In January 1989, the temperature in Nome, Alaska dropped to −49° F. Would the gas in the driver's truck have remained in liquid form so he could have driven on this day? Why or why not?
The inequality that represents the temperatures at which the gas in the truck will remain in liquid form is; -40°F < x < 140°F
How to solve Inequality Word Problems?
A) x is the temperature, and the temperature can't go down to -40°F and so x is greater than -40°F so that the gas doesn't freeze. Finally, x can't go higher than 140°F because the gas will evaporate. Thus, the inequality that represents the temperatures at which the gas in the truck will remain in liquid form is;
-40°F < x < 140°F
B) Open interval of the graph would mean that the interval is from -40°F to < 140°F. However, not equal to means that the gas in the truck can't stay liquid and as such means the coordinate is (-40°F, 140°F)
C) The gas will freeze because it has been said in the question the gas freezes at -40°F and as such if it goes -49°F, then it will freeze because the gas is supposed to stay higher than -40°F.
