hahahaaha i cant believe no one answered this yet, they probably thought this was an actual math problem they had to use much braincells for-

The answers for addition are 3,49,59 and multiplication are 0 and 25.

Any symbol that denotes a mathematical operation is known as an operator. Examples are d/dx and Square root of x (which implies that the square root should be taken) (which indicates differentiation with respect to x is to be performed).

These operators are + for addition, - for subtraction, * for multiplication, / for division, and % for percentage (modulo).

So:

2+1=3

40+9=49

56+3=59

2*0=0

5*5=25

Therefore,The solutions to the addition and multiplication problems are 0 and 25 respectively.

$1470 more money  does Michael have  than Steven after 1 year.

The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned.

Rate of interest is simple interest for Steven in a savings account. He can withdraw his money any time he wishes to.

Steven will receive after 1 yr an interest payment of

=35000×1.8/100

=35000×0.018

=630

Michael invests his inheritance in a CD (Certificate of Deposit) account. He gave up access to his money for a specified period of time. Assuming that given rate of interest is annual.

=35000×6/100

=35000×0.06

=2100

Therefore, Micheal has more money than Steven.

=2100-630

=1470.

Hence $1470 more money  does Michael have  than Steven after 1 year.

Given,

The amount Gagu is paid = £1200 per month

The increase he is going to get = 4%

We have to find the amount Gagu gets after the increase:

First we have to find the increment amount:

That is,

4% of 1200

= 1200 × (4/100)

= 12 × 4

= 48

Here,

£48 is the increment amount Gagu will get.

Now we can calculate the monthly amount gagu will be paid after the increase.

That is,

Explanation:

The x coordinates are the same, so we subtract the y coordinates and use absolute value to ensure the result isn't negative.

|-30.5 - 9.7| = |-40.2| = 40.2

One unit represents 1 km, so 40.2 units represent 40.2 km

This converts to 40,200 meters. Multiply by 1000 to go from km to meters.

The value of k in the expression is equal to 9.

The expression is in the form of Cubic polynomial. A cubic polynomial is the one which can be written in the form y = ax³ + bx² + cx + d where a, b, c and d are coefficients and x, and y are independent and dependent variables respectively. The cubic polynomial f(x) = 2x³ + (k)x - 11 has a factor equal to (x-1). If it is the factor, then x = 1 is the solution of cubic polynomial and at x = 1 the value of f(x) = 0.

2(1)³ + k(1) - 11 = 0

2 + k - 11 = 0

k - 9 = 0

The skid distance value that will be used when calculating the skid speed formula is 58.5 ft.

What is average of values and how is it defined?
The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average. In mathematics, the central value of a set of data is expressed as the average of a list of data. It is defined mathematically as the ratio of the total number of data points to the number of units in the list. In terms of statistics, the term "mean" also refers to the average of a certain set of numerical data. As a result, the following is the mathematic average formula:
Average = Sum of values/Set of values = (x₁ + x₂ + ... + xₙ)/n

Given, the first skid distance calculated, in feet = x₁ = 55
The second skid distance calculated, in feet = x₂ = 55
The third skid distance calculated, in feet = x₃ = 62
The fourth skid distance calculated, in feet = x₄ = 62
Therefore using the formula for average mentioned in the literature at n=4, we have,
Average skid distance = (55 + 55 + 62 + 62)/4 = 234/4 = 58.5 ft.
Thus, the skid distance value that will be used when calculating the skid speed formula is 58.5 ft.

y=x+23 is the linear equation that gives the rule for the given table .

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.

The following is how the linear equation can be expressed in a slope-intercept form:

y = mx + b

where

slope = m

y-intercept = b

Using the table we get two points:

(1,24) and (2,25)

slope= y2-y1/x2-x1

= 25-24/2-1

=1

Now we have to calculate B using the point (1,24) and putting values in equation y=mx+b

24=1+b

b=23

So the equation is :

y=x+23

Therefore the linear equation for the given set of data table is  y=x+23.

Some of the terms of an equation that has missing terms will be eliminated.

100 is the missing term that transforms (x² - 20) into a perfect square.

What is a  perfect square?

A perfect square is a number that can be written as the product of an integer multiplied by itself or as the integer's second exponent. For instance, the number 25, which is the product of the integer 5 multiplied by itself, is a perfect square because 5 x 5 = 25.

The missing term will be calculated in the next step.

Use k to represent the x-coefficient.

We thus have:

k = -20

Divide both sides by 2

k/2 = - 10

squaring both the sides,

(k/2)² = (- 10)²

=> (k/2)² = 100

Answer: Choice D

Step-by-step explanation

First, subtract Ax from both sides:

Ax - Ax + By = C - Ax

By = C - Ax

Now, divide B from both sides:

[tex]\frac{By}{B}[/tex] = [tex]\frac{C - Ax}{B}[/tex]

y = [tex]\frac{C - Ax}{B}[/tex]

Finally, to get an equivalent answer for an answer choice, divide each term by B on the right side of the equation:

y = [tex]\frac{C}{B}[/tex] - [tex]\frac{Ax}{B}[/tex]

     or

y = -[tex]\frac{Ax}{B}[/tex] + [tex]\frac{C}{B}[/tex]

     or

y = [tex]\frac{-Ax}{B}[/tex] + [tex]\frac{C}{B}[/tex]

This answer is the same as answer choice D, and so D is the correct answer.

Answer: D.

Step-by-step explanation:

[tex]Ax+By=C\\Ax+By-Ax=C-Ax\\By=C-Ax\\[/tex]

Divide both parts of the equation by B:

Answer:

n = 1

Step-by-step explanation:

-12 = -6(-8n + 6) + 8(-4 + n)

multiply our right side:

-12 = 48n - 36 -32 + 8n

combine n terms on right side:

-12 = 56n - 36 -32

combine numbers on right side:

-12 = 56n - 68

add 68 to both sides:

-12 + 68 = 56n - 68 + 68

56 = 56n

divide both sides by 56:

56/56 = 56n/56

n = 1

check:

-12 = -6(-8(1) + 6) + 8(-4 + (1))

-12 = -6(-8 + 6) + 8(-3)

-12 = -6(-2) + 8(-3)

-12 = 12 - 24

-12 = -12

The equations for the coordinates of the endpoint F should be x = 2 · 35 - 15 and y = 2 · (- 3) - 26.

In this problem we know the coordinates of the endpoint E and the midpoint M of the line segment EF and we need to derive expressions of the coordinates of the endpoint F by the midpoint formula:

M(x, y) = 0.5 · E(x, y) + 0.5 · F(x, y)

2 · M(x, y) = E(x, y) + F(x, y)

F(x, y) = 2 · M(x, y) - E(x, y)

If we know that M(x, y) = (35, - 3) and E(x, y) = (15, 26), then the coordinates of the endpoint F are:

F(x, y) = 2 · (35, - 3) - (15, 26)

F(x, y) = (70, - 6) + (- 15, - 26)

The endpoint F's coordinates should be given by the formula

x = 2×35 - 15 and y = 2×(- 3) - 26.

In order to solve this problem, we need to derive expressions for the coordinates of the endpoint F using the midpoint formula.

We know the coordinates of the endpoint E and the midpoint M of the line segment EF.

M(x, y) = 0.5×E(x, y) + 0.5×F(x, y).

2×M(x, y) = E(x, y) + F(x, y).

F(x, y) = 2×M(x, y) - E(x, y).

Given that M(x, y) = (35, -3) and E(x, y) = (15, 26), the endpoint F's coordinates are,

F(x, y) = 2×(35, - 3) - (15, 26).

F(x, y) = (70, - 6) + (- 15, - 26).

F(x, y) = (55, - 32).

The statements about Alina's and Cesar’s estimates should be completed as follows:

Percentage error is also referred to as percent error and it can be defined as a measure of the extent to which an experimental numerical value differs from the actual (theoretical) numerical value.

Mathematically, percentage error can be calculated by using this expression;

[tex]Percent\; error = \frac{Actual\;value - Experimental\;value}{Experimental\;value} \times 100[/tex]

For the Alina's result, we have:

Difference = Actual mileage - Estimated mileage

Difference = 50 miles - 45 miles

Difference = 5 miles.

Next, we would determine Alina's percentage error as follows:

Percentage error = 5/50 × 100

Percentage error = 500/50

Percentage error = 10%.

For the Cesar's result, we have:

Difference = Actual mileage - Estimated mileage

Difference = 200 miles - 190 miles

Difference = 10 miles.

Next, we would determine Cesar's percentage error as follows:

Percentage error = 10/200 × 100

Percentage error = 1000/200

Sarah earned $10 per hour for babysitting

Step-by-step explanation:

The net pay of  Alisha Gregory  is $30606.4

Since we are given the weekly gross  pay of her  is $640

The annual gross pay will  be  52 *  640 =33280.

Here the local income tax is  1.5% of the gross, which is  1.5/100 * 33280  = 499.2 and  it is also specifically said that the state tax is the 3.0% of taxable income.

So we have:

3/100 * 33280= 998.4

The medical insurance is $1,940 for a year from where the company  pays 60 %

For which we have:

60/100 *1940

= 1164

At the last he pays  $4.50  for union dues and $7.50 for others.

Since we know that the net pay is nothing but the amount we get after subtracting the deductions from the annual gross pay

So the net pay = 33280- (499.2+998.4+1164+4.50+7.50)

                         =  33280  -(2673.6)
