Hence option B

She is paid an hourly rate plus 10% commission on everything she sells

Total amount she get = Hourly rate + 10% on sale price of the objects

One week she was paid $381.25 for working 15 hours and selling $1,225 worth of books.

Let the hourly wages is x

She paid $381.25 for working 15 hours

for hourly rate divide the amount by number of hours :

The hourly rate is $25.416

Answer : The hourly rate is $25.416

The value of the expression, [tex]17c^{9} d^{4} -2c^{3} d^{9} .3c^{6} d^{-5}[/tex], after simplification with only positive exponents is [tex]11c^{9} d^{4}[/tex].

According to the question,

We have the following expression:

[tex]17c^{9} d^{4} -2c^{3} d^{9} .3c^{6} d^{-5}[/tex]

Now, we know that we will first solve terms in multiplication and we also that if numbers with same base are in multiplication then their powers are added.

So, we will have the following expression:

[tex]17c^{9} d^{4} -6c^{3+6} d^{9-5\\}\\17c^{9} d^{4} -6c^{9} d^{4}[/tex]

Now, they have the same variables so the terms can be easily subtracted.

(More to know: if the variables would have been different in these two terms then they could not have been subtracted.)

[tex]11c^{9} d^{4}[/tex]

Hence, the value of the expression, [tex]17c^{9} d^{4} -2c^{3} d^{9} .3c^{6} d^{-5}[/tex], after simplification with only positive exponents is [tex]11c^{9} d^{4}[/tex].

The total number of square cardboards that can be placed is 35 square pieces.

Length of the class board = √150dm

Length of the square side = √3 dm

Number of cardboards that can be cut = √150 ÷ √3 = 7.07 ≈ 7

Width of the square = √80 dm

Number of cardboard pieces =  √80 ÷ √3 = 5.16 ≈ 5

Total number of cardboard squares = 7 × 5 = 35 pieces

The factored form of the quadratic equation 2x² + 25x + 50 is (2x + 5)(x + 10)

Factoring quadratics is a method of expressing the quadratic equation ax² + bx + c = 0 as a product of its linear factors as (x - k)(x - h), where h, k are the roots of the quadratic equation ax² + bx + c = 0.

Therefore, let's factor the equation 2x² + 25x + 50.

2x² + 25x + 50

The two numbers one can multiply and add to get 100 and 25 respectively are 20 and 5.

Therefore,

2x² + 20x + 5x + 50

2x(x + 10)+ 5(x + 10)

Division is the opposite of multiplication. If you divide 12 into three equally sized groups, you will get four in each group if the three groups of four sum up to 12, which they do when you multiply. The main goal of division is to count the total number of evenly distributed groups or the total number of people in each group following a fair distribution.

The slope intercept form of the required line is x -2y = 12

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

The given line is

[tex]x - 2y = 16\\2y = x - 16\\y = \frac{1}{2}x - \frac{16}{2}\\[/tex]

Slope of the line = [tex]\frac{1}{2}[/tex]

Slope of the line parallel to this line = [tex]\frac{1}{2}[/tex]

The line passes through (2, -5).

Equation of the required line-

[tex]y - (-5)= \frac{1}{2}(x - 2)\\2y + 10 = x - 2\\ x - 2y = 10 + 2\\x-2y = 12[/tex]

The coordinates of the vertex and the range of the function y = |3 · x + 6| - 4 are (x, y) = (- 2, - 4) and y ≥ - 4, respectively. (Correct choice: B)

In this problem we have an absolute value function of the form y = |a · x + b| + c, of which we need to determine the coordinates of the vertex and the range of the function. The coordinates of the vertex is the point of the function such that:

x-Coordinate

|a · x + b| = 0

a · x + b = 0

x = - b / a

y-Coordinate

y - c = 0

y = c

And the range of the function is:

y ≥ c

If we know that a = 3, b = 6 and c = - 4, then the coordinates of the vertex and the range of the function are, respectively:

Justin"s heart rate decreased 3 beats per minute for each of next 4 minutes

Let his heart rate be be 1

For the first minutes

1 minute his heart rate was 1 - 3 = -2

This is because the heart rate is decreasing 3 beats per minutes

2minutes later, his heart beat will be -2 -3

-2 - 3 = -5

3 minutes later, his heart beat will be -5 - 3

-5 - 3 = -8

4 minutes later, -8 - 3

-8 - 3 = -11

Change = Final heart beat - initial heart beat / initial heart beat

Change = -11 -2 / -2

Change = -13/-2

Change = 13/2

Assuming the goal is to construct a line parallel to AB that passes through given point C.

-Draw a line through C and across AB at an angle creating D.

- With the compass width about half of DC, and center D, draw the first arc to cross both lines.

-Using the same compass width , draw the second arc with center C.

-Then set the compass width to the lower arc (the first arc)

- Move the compass to the second arc. Mark off an arc to make point E

-Draw a straight line through C and E

You can make one and a half smoothies from one oz of acai juice

Given that:

smoothie recipe uses 2/3 oz of acai juice to make one smoothie and

Acai juice comes in a 5-oz container

In order to know how many smoothies can be made from one container, you divide the volume of the Acai juice container by the volume needed to make one smoothie. Thus the equation is:

No. of smoothies = volume of container/volume needed for one smoothie

The number of smoothies that can be made from one oz of acai is:

No. of smoothie = 1/(2/3) =  1 1/2 smoothies

What is unitary method?

Unitary method is the process in which the value of single unit can be calculated from the value of multiple unit and the value of multiple unit can be calculated from the value of single unit. Sometimes Value of single unit can be less than the value of multiple unit. For example - The relation between the cost of a commodity and the quantity of the commodity

Sometimes Value of single unit can be more than the value of multiple unit. For example - The relation between the number of men and the number of days taken by those men to do a certain job.

Here, unitary method is used

FOIL Method! (EXPLAINED BELOW)

Step-by-step explanation:

FOIL MEANS First Out In Last.

For example:

Binomial: (a+b) (a+b)

STEP 1: Multiply the first term of each bracket.

      (a+b) (a+b)

      So, a * a =    [tex]a^{2}[/tex]

      The number would be positive since both terms are positive.

STEP 2: Multiply the outer terms.

      (a+b) (a+b)

      So, a * b = ab

      The number would be positive since both terms are positive.

STEP 3: Multiply the inner terms.

       (a+b) (a+b)

      So, a * b = ab

      The number would be positive since both terms are positive.

STEP 4: Multiply the last terms.

       (a+b) (a+b)

       So, b * b = [tex]b^{2}[/tex]

      The number would be positive since both terms are positive.
