Janine is an employee for a company whose gross earnings were $100,000 in 2018. Calculate Janine's Social Security portion
of the FICA tax for 2018.
Given that, for this earnings amount, the current tax rate for social security is 6.2% for the employer and 6.2% for the
employee, how much did Janine have to pay in FICA taxes for 2018?
Answers
Answer:
$6,200
Step-by-step explanation:
6.2% of $100,000 is
$100,000 × 0.062 = $6,200
Janine paid $6,200 in Social Security taxes for 2018.
Answer:
Step-by-step explanation:
The social security portion of the FICA tax is calculated as 6.2% of the first $128,400 gross earnings. Since Janine's gross earnings are less than this amount, her entire gross earnings are subject to the Social Security tax.
$100,000×0.062= $6,200
Thus, $6,200 will be deducted from Janine's paychecks over the course of 2018.

How many cups of cream would you need for 7 cups of sugar?
Answers
Answer:
28 cups of cream.
Step-by-step explanation:
With the information given in the table, we can set up a ratio:
4:1 = x:7 (where x is the unknown). If you multiply the denominator by 7 then you also have to multiply the numerator by 7 as well. Therefore, 4 * 7 is 28.
Hope this helps :)
Answer:
You would need 28 cups of ice cream for 7 cups of sugar.
For 1 cup of sugar you would need 4 cups of ice cream so we multiply 4 by 7 to find the answer.

what percent of students have an IQ of at least 130
Answers
A percentage of students who have an IQ of at least 130 is 7%.
What is the percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given a Frequency chart of IQ of 7th grades students.
students have an IQ of at least 130 = 9+ 4 + 1
students have an IQ of at least 130 = 14
Total students = 2+ 4 + 13 + 46 + 48 + 41 + 32 + 9 + 4 + 1
Total students = 200
thus percentage = 14 /200 * 100
Percentage = 7%
therefore, a percentage of students who have an IQ of at least 130 is 7%.

The two isosceles triangles formed by the median line indicates that

Response:
The measure of the smallest angle of ΔDEF is 19°Which method can be used to find the smallest angle?The given parameters are;
DM is a median of ΔDEF
M ∈ EF
[tex]DM = \mathbf{ \frac{1}{2} \cdot EF}[/tex]
DL is an angle bisector of ∠EDF
Required:
The measure of the smallest angle of ΔDEF
Solution:
ΔDME and ΔFMD are isosceles triangles by definition of isosceles
triangles.
∠MDF = ∠MFD base angles of an isosceles triangle
∠MDE = ∠MED base angles of an isosceles triangle
∠MDF + ∠MFD + ∠MDE + ∠MED = 2·∠MDF + 2·∠MED = 180° by angle sum property of a triangle
∠MDF + ∠MED = 90°
∠DLF = ∠MED + ∠LED by exterior angle theorem
∠MED + ∠LDE = 64° by substitution property of equality
∠EDF = ∠MDF + ∠MED by angle addition property
[tex]\angle LDE = \dfrac{\angle EDF}{2} = \dfrac{\angle MDF + \angle MED}{2} = \dfrac{90^{\circ}}{2} = \mathbf{ 45 ^{\circ}}[/tex]∠MED = 64° - ∠LDE
∠MED = 64° - 45° = 19°
∠MFD = 90° - 19° = 71°
∠EDF = 90°
In triangle ΔDEF, ∠MED = 19°, ∠MFD = 71°, ∠EDF = 90°

[tex]\sf{\boxed{\sf{x=3, \quad y=-7}}}[/tex]
Step-by-step explanation:
In order to solve the problem, all you have to do is substitute the left to right numbers in the equation.
-4x-3y=9 and 5x=15
Solve with 5x=15.
First, divide by 5 from both sides.
5x/5=15/5
Solve.
15/5=3
x=3
Substitute of x=3.
-4*3-3y=9
Solve.
-4*3=-12
Then rewrite the problem down.
-12-3y=9
You have to isolate by the y.
-12-3y=9
Add by 12 from both sides.
-12-3y+12=9+12
Solve.
9+12=21
-3y=21
Then, divide by -3 from both sides.
-3y/-3=21/-3
Solve.
21/-3=-7
y=-7
As a result, the solution is x=3, and y=-7, which is our answer.

Answer:
x = 5
Step-by-step explanation:
(9 - x) × 10 = 40
90 - 10x = 40
90 - 40 = 10x
50/10 = 10x/10
x = 5
Step-by-step explanation:
A number is subtracted from 9. We can call this number "x."
9-x is our first part. Now the problem is saying that the result is multiplied by 10.
10(9-x)
Now the problem is saying that this expressions is equal to 40. Now we have constructed the equation 10(9-x) = 40. Now let's solve!
10(9-x) = 40
divide each side by 10.
9-x=4
subtract 9 from both sides
-x=-5
multiply each side by -1

Step-by-step explanation:
please mark me as brainlest
Answer:
The total amount is ₹900.
Step-by-step explanation:
In this question, it is said that 12% of the total amount is ₹108 and we need to find the total amount.
So, let the total amount be x.
Now, according to the question :
[tex] \implies{\tt{12 \% \: of \: x = 180}}[/tex]
[tex] \implies{\tt{\dfrac{12}{100} \: of \: x = 180}}[/tex]
[tex] \implies{\tt{\dfrac{12}{100} \times x = 180}}[/tex]
[tex] \implies{\tt{\dfrac{12 \times x}{100} = 180}}[/tex]
[tex] \implies{\tt{\dfrac{12x}{100} = 180}}[/tex]
[tex] \implies{\tt{x= 180 \times \dfrac{100}{12}}}[/tex]
[tex] \implies{\tt{x= \cancel{180} \times \dfrac{100}{\cancel{12}}}}[/tex]
[tex] \implies{\tt{x= 9 \times 100}}[/tex]
[tex] \implies{\tt{x = 900}}[/tex]
Hence, the total amount is ₹900.
