Veronika works as a cook at Toyem Catering, she makes $58,200/year. She pays 18% in taxes and $125/month for health insurance. What is Veronika's net income per month?
a
$4,200
b
$3,852
c
$4,850
d
$2,989
Veronika's net income per month is $3,852. Option B
How to calculate Veronika's net income per monthThe annual amount of taxes that Veronika pays:
Annual taxes = 0.18 x $58,200 = $10,476
Annual health insurance = $125/month x 12 months = $1,500
we can calculate Veronika's net annual income by subtracting the taxes and health insurance from her annual salary:
Net annual income = $58,200 - $10,476 - $1,500 = $46,224
We can calculate her net income per month by dividing her net annual income by 12:
Net monthly income = $46,224/12 = $3,852

What is the green dashed line called?
Answer:
The line (or "axis") of symmetry is the y-axis, also known as the line x = 0. This line is marked green in the picture. The graph is said to be "symmetric about the y-axis", and this line of symmetry is also called the "axis of symmetry" for the parabola.
The equation of the function g(x), after the translation, is given as follows: g(x) = (x + 2)² + 4.
What is a translation?A translation happens when either a figure or a function are moved horizontally or vertically.
The four translation rules for functions are given as follows:
Left a units: f(x + a).
Right a units: f(x - a).
Up a units: f(x) + a.
Down a units: f(x) - a.
The parent function for this problem is given as follows:
f(x) = x².
For this problem, the parent function was moved:
2 units left, hence g(x) = f(x + 2).
4 units up, hence g(x) = f(x + 2) + 4.
Hence the function g(x) is defined as follows:
g(x) = (x + 2)² + 4.

x + 9 - 4x = -3x - 3
A. There is only 1 solution, and x = -3.
B. There is only 1 solution, and x = 9.
C. There are infinitely many solutions because the variables cancel each other.
D. There is no solution because 9 ≠ -3.
Answer:
D. There is no solution because 9 ≠ -3.
Step-by-step explanation:
For finding out the statement let's check it ourselves
x + 9 - 4x = - 3x - 3
-3x + 9 = - 3x - 3
9 ≠ - 3
So there is no solution for the equation.

Step-by-step explanation:
What is the value of this expression? 6 + (-9) - (-5)
6 + (-9) - (-5)
= 6 - 9 + 5
Following the rules of BODMAS, addition comes first before subtraction
= 6 - 14
= - 8
6 + (-9) - (-5) = -8
Note:
- * - = +
- * + = -
+ * - = -
+ * + = +

Answer:
(111.5, 155.5)
Step-by-step explanation:
Given the data:
132 127 106 140 158 135 129 138
The Outlier formula :
Lower = Q1 - 1.5(IQR)
Higher = Q3 + 1.5(IQR)
Using a calculator :
Q1 = 128
Median, Q2 = 133.5
Q3 = 139
IQR = Q3 - Q1 = 139 - 128 = 11
Lower = Q1 - 1.5(IQR) = 128 - 1.5(11) = 111.5
Higher = Q3 + 1.5(IQR) = 139 + 1.5(11) = 155.5
(111.5, 155.5)

Omar is planning to buy some new baseball shoes. He has already saved $22.50 The shoes cost at least $38 dollars. He writes an inequality to determine how much more he will need to save
Answer:
At least $15.50
Step-by-step explanation:
Omar is planning to buy some new baseball shoes. He has already saved $22.50
The shoes cost at least 38 dollars.
At least means, greater than or equal to which is represented by the sign
≥
The inequality is given as
22.50 + x ≥ 38
x ≥ 38 - 22.50
x ≥ 15.5
Therefore, he would need to save at least $15.50

Find the additive inverse of 3x−6
Answer:
3x+6
Step-by-step explanation:
inverse means the opposite of the sign and the opposite of subtraction is addition so I used addition
The additive inverse of 3x − 6 is -3x + 6
What is additive inverse?
The additive inverse of a number x is a number that when added to x gives a result of 0.
For the expression 3x - 6
The additive inverse is a number that can be added to the expression to get 0. Hence:
The additive inverse of 3x − 6 is -3x + 6

C. c = d + 3
D. c = d + 3d
Answer: A. c = 3d
I'm gonna go with c = 3d
Step-by-step explanation: c = 3d
After looking at the table I believe the equation would be c=3d. I came to this conclusion because (6)=3(2); (9)=3(3); (15)=3(5); 18=3(6). I really hope this helps!:)

Now to find equation that models the given data we will use two point slope form.
Formula:
Substitute the values in the formula
where y denotes the number of days and x denotes the cost
Let us suppose d denotes the number of days and c denotes the cost
So, equation becomes:
Hence an equation models the data in the table is
So, option A is true.
A fourth grade teacher gives homework every night in both mathematics and language arts. The time to complete the mathematics homework has a mean of 10 minutes and a standard deviation of 3 minutes. The time to complete the language arts assignment has a mean of 12 minutes and a standard deviation of 4 minutes. The time to complete the mathematics and the time to complete the language arts homework has a correlation rho = -0.75. The variance of the time to complete the entire homework assignment is
Answer:
4
Step-by-step explanation:
Given that:
X = time taken to complete mathematics homework
Y= time taken to complete language homework
Standard deviation of X ; SD(X) = 3
Standard deviation of Y ; SD(Y) = 4
rho = - 0.375
rho = Cov(X, Y) / SD(X) * SD(Y)
-0.375 = COV(X, Y) / 3 * 4
COV(X, Y) = 12 * - 0.375
COV(X,Y) = - 4.5
Variance(X, Y) = V(X, Y)
V(X, Y) = V(X) + V(Y) + 2COV(X,Y)
V(X) =SD(X)² = 3² = 9
V(Y) = SD(Y)² = 4² = 16
V(X,Y) = 9 + 16 + 2(-4.5)
V(X, Y) = 16
SD(X, Y) = sqrt(V(X, Y)) = sqrt(16) = 4
Hence, standard deviation to complete entire homework, SD(X, Y) = 4
Andy wants to buy a used car that cost $8,500. He has
saved $1,300 and can save an additional $225 each month.
How many months will it take for Andy to have enough
money for the car?
Answer:
32 months.
Step-by-step explanation:
Andy wants a car that costs $8,500.
He already saved $1,300.
$8500 - $1300 = $7200
Andy can save an additional $255 each month.
7200 ÷ 255 = 32
So, it would take Andy 32 months to have enough money to buy the car.

ayudenme plis
Answer:
a. Velocidad = 16 m/s
b. Deceleración = 0.64 m/s²
Step-by-step explanation:
Dados los siguientes datos;
Tiempo = 25 segundos
Distancia = 400 metros.
a. Para encontrar la velocidad;
Velocidad = distancia/tiempo
Velocidad = 400/25
Velocidad = 16 m/s
b. Para encontrar la desaceleración;
Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.
Deceleración = (v - u)/t
Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.
Deceleración = (0-16)/25
Deceleración = 16/25
Deceleración = 0.64 m/s²
