Answer:
4x-20
Step-by-step explanation:
2+5x-1x-22
First, rearrange to make life temporarily easier.
5x-1x+2-22
Then combine like terms.
5x-1x=4x
2-22=-20
So we have 4x-20
That is simplified as far as it can.

meteroloogist track severe stoms using Doppler radar. A polar grid is used to measure distances as the storms progress. If the center of the radar screen is the origin and each ring is 10 miles farther from the center, what is the equation of the fourth ring
Answer:
[tex]$(x-h)^2+(y-k)^2= (r+ 40 )^2$[/tex]
Step-by-step explanation:
It is given that a meteorologist is using a Doppler radar to find out the distance of the storm as it passes using a polar grid.
The origin of the radar screen is its center.
And the distance between each ring is 10 miles from the center.
So let :
r = radius
h and k = be the coordinates of the center.
So the equation of a circle is :
[tex]$(x-h)^2+(y-k)^2= r^2 $[/tex]
Now the equation of the fourth circle when the radius changes by 10 miles is :
[tex]$(x-h)^2+(y-k)^2= (r+ 40 )^2$[/tex]

when can a parallelogram also be a kite?
9514 1404 393
Answer:
when it is a rhombus
Step-by-step explanation:
A kite is a figure in which the diagonals are perpendicular, and one of them is bisected by the other. It will be a parallelogram if both diagonals bisect each other. Such a figure (with mutually perpendicular bisectors as diagonals) is a rhombus.
A parallelogram that is a rhombus will also be a kite.

Answer:
hfgf td utdu6kjyyyudytdcyu6 vfhdutd,ld
Step-by-step explanation:
1. The value of A, the Net Salary received by Mr. Makatle is R 5,369.49 (R8,236,00 - R 2 866,51), which is the gross pay minus total deductions.
2. The UIF contribution of R82.36 was calculated as 1% of R8236,00 (R 8,236 x 1%).
3. Mr. Makatle's claims that the cumulative medical contributions indicated on his pay advice are incorrect are valid.
The cumulative medical contributions for the year are supposed to total R 17,640 (R 1 764,00 x 10) instead of R 6,177.00, which represents the pension's cumulative contributions.
4. Mr. Makatle's monthly tax contribution as a percentage of his gross salary is 4.8865%.
Tax contribution = R 402.45
Gross monthly salary = R 8 236
Percentage of tax contribution to gross salary = 4.8865% (R402.45/R8,236 x 100)
5. For question 2, we can use the rates computed from Mr. Makate's salary advice to calculate Danielle's net pay for the year.
Danielle's Net Pay:Basic Salary FR 45 600,50
PAYE R 2,228.27 (4.8865%)
UIF R 456.01 (1%)
Pension Fund R 3 420. 04 (7.5%)
Medical Aid contribution R 9,766.72 (21.418%)
TOTAL DEDUCTIONS R 15,871.04
NET SALARY R 29,729.46
What is net pay?The net pay is the difference between a salary earner's gross income and the deductions made before the payment of salary.
The net pay represents the amount that the salary earner goes home with.
The net pay is also known as the take-home pay.
Question Completion:Mr. Paul Makatle is an employee at a clothing factory The following deductions are made from his gross monthly salary:
• 7,5% of his gross monthly salary for pension fund contributions
• UIF (Unemployment Insurance Fund) of 1% of his gross monthly salary
• PAYE (Pay as you earn) tax as per tax bracket
Use the salary advice below that Mr. Makatle receives for December 2020 to answer the questions that follow.
Basic Salary R 8 236,00
PAYE R 402.45 (4.8865%)
UIF R 82,36 (1%)
Pension Fund R 617,70 (7.5%)

From -55, it’s showing small than
From -49, it’s showing greater than
x < -55 or x > -49
Answer: x < -55 or x > -49
Step-by-step explanation:
x < -55 or x > -49
They both start with an opened circle, and also these two opened circle dots do not connect to each other. On the left side, the number is going from -55 to the smaller side, -57 or less, so we can say that x is smaller than -55. On the right side, the number goes from -49 to the bigger number, we can say that x is greater than -49.
If your weekly salary is $1780 and taxes takes out $440, then what percent do you pay in taxes?
Round your answer to 1 decimal place.
Answer:
24.7
Step-by-step explanation:
If your weekly salary is $1780 and taxes takes out $440, then 24.7% you pay in taxes.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that the weekly salary is One thousand seven hundred and eighty $1780.
Taxes takes out is four hundred and forty $440.
We need to find the percent of tax we have paid.
This can be found by as below.
1780x=440
Divide both sides by 1780
x=440/1780
x=0.247
Now multiply with 100 as it is a hundredth part
0.247×100=24.7%
Hence, 24.7% is the percentage of tax we have paid.

in the figure below ABC- XZY
find cosZ, sin Z, tan Z
round your answer to the nearest hundredth
The magnitude of angle Z include the following:
cosZ = 0.471
sinZ = 0.88
tanZ = 1.875
How to calculate the magnitude of angle Z?In order to determine the magnitude of angle Z, we would apply the basic trigonometric ratio because the given side lengths represent the adjacent side, opposite side, and hypotenuse of a right-angled triangle.
cos(θ) = Adj/Hyp
Where:
Adj represents the adjacent side of a right-angled triangle.Hyp represents the hypotenuse of a right-angled triangle.θ represents the angle.For cosZ, we would apply the cosine trigonometric ratio as follows;
cosZ = 13.6/28.9
cosZ = 0.4706
Z = cos⁻¹(0.4706)
Z = 61.93°.
For sinZ, we would apply the sine trigonometric ratio as follows;
sinZ = 25.5/28.9
sinZ = 0.8824
Z = sin⁻¹(0.8824)
Z = 118.07.
For tanZ, we would apply the sine trigonometric ratio as follows;
tanZ = 25.5/13.6
tanZ = 1.875
Z = tan⁻¹(1.875)
Z = 61.93.

complete question
study by Allstate Insurance Co. finds that 82% of teenagers have used cell phones while driving ( The Wall Street Journal , May 5, 2010). In October 2010, Massachusetts enacted a law that forbids cell phone use by drivers under the age of 18. A policy analyst would like to determine whether the law has decreased the proportion of drivers under the age of 18 who use a cell phone.a. State the null and the alternative hypotheses to test the policy analyst’s objective.
b. Suppose a sample of 200 drivers under the age of 18 results in 150 who still use a cell phone while driving. What is the value of the test statistic? What is the p-value?c. At α = 0.05 has the law been effective?
d. Repeat this exercise using the critical value approach with α = 0.05
Answer:
1. H0: p>=0.82
H1: p<0.82
2. z test statistic = -2.5767
3. the law has been effective
4. the null is rejected, the law has been effective
Step-by-step explanation:
1. hypothesis formulation
H0: p>= 0.82
H1: p< 0.82
2. p = 82% = 0.82
estimated p^ = x/n = 150/200 = 0.75
standard error calculation:
= √0.82(1-0.82)/200
= √0.82x0.18/200
= √0.02716615
Z test statistic calculation:
= 0.75-0.82/0.02716615
= -2.5767
3. this test is 1 tailed
the p-value using a p value calculator is = 0.004983
0.004983 < 0.05 so we Reject null and conclude that the law has been effective.
4. we Reject null at 0.05 if z is less than -1.645.
-2.5767<-1.645 so we Reject H0 and conclude law has been effective and there is a decrease in drivers under this age who use cell phones
