Commission earned by William is $ 45.84

Given that,

William makes a commission of 6% percent on everything he sells

He sells a computer for $764.00

To find: Commission amount of William

Given that he makes a commission of 6 % on everything he sells. So he has received a commission of 6 % of $ 764.00

Commission amount of William = 6 % of $ 764.00

a % of b can be written in fraction as [tex]\frac{a}{100} \times b[/tex]

[tex]6 \% \text { of } 764=\frac{6}{100} \times 764=0.06 \times 764=45.84[/tex]

Thus commission earned by William is $ 45.84

Answer:

x = 30, y = 18

Step-by-step explanation:

Given the 2 equations

x - 2y = - 6 → (1)

x - y = 12 → (2)

Subtracting (2) from (1) term by term will eliminate the term in x

||(x - x) + (- 2y - (- y)) = (- 6 - 12), that is

- y = - 18 ( multiply both sides by - 1 )

y = 18

Substitute y = 18 into either of the 2 equations for value of x

Substituting in (2)

x - 18 = 12 ( add 18 to both sides )

x = 30

Answer: (30,18)

x - 2y = -6

x - y = 12

x - y = 12

- y = 12 - x

y = -12 + x

x - 2y = -6

x = -6 + 2*y

y = -12 + (-6+ 2*y)

y = -12 - 6 + 2*y

y - 2*y = -18

-y = -18

y = 18

y = -12 + x

18 = -12 + x

-x = -12 - 18

x = 12 + 18

x = 30

Her gross pay is $118.50

Step-by-step explanation:

Firstly, find out how much she earn in each day :

Day 1 => 3.3hr × $7.50

= $24.75

Day 2 => 2.9hr × $7.50

= $21.75

Day 3 => 4.0hr × $7.50

= $30.00

Day 4 => 3.5hr × $7.50

= $26.25

Day 5 => 2.1hr × $7.50

= $15.75

Lastly, sum up altogether to calculate how much she earns in 5 days:

$24.75 + $21.75 + $30 + $26.25 + $15.75

= $118.50

Answer:

S = 2 - 0.25W

Step-by-step explanation:

A lake near the Arctic Circle is covered by a  2 meters thick sheet of ice during the cold winter months.

At the warm air of spring gradually melts the ice thickness gradually.

Therefore, the equation that models the situation is S = 2 - bW ....... (1), where S is the remaining thickness of the ice sheet and W is the number of weeks passed and b is the rate of decrease of ice sheet thickness with respect to the number of weeks.

Now, putting W = 3 weeks and S = 1.25 meters in the equation (1) we get,

1.25 = 2 - 3b

⇒ 3b = 0.75

⇒ b = 0.25 meters per week.

Therefore, the equation (1) becomes S = 2 - 0.25W (Answer)

Answer:

y = 5/2x + 5

Step-by-step explanation:

Your b value is the place where the line crosses the y-axis. So, we can tell right away the b value in the equation is 5.

I'll use negative 2 as the point to find the slope. You go down 5, so we have -5, and go left 2, so -2. 2 negatives make a positive, so the slope is 5/2.

Final equation -

y = 5/2x + 5

The number of minutes of call for long distance is 500 minutes .

Step-by-step explanation:

Given as :

The two different long distance telephones plans are plan A and Plan B

Plan A

monthly fee = $40.00

The charge per minute = $0.05

Plan B

monthly fee = $15.00

The charge per minute = $0.10

now, for both plans

Let The number of minutes of call for long distance = n minutes

So, According to question

∵ The both plans to be same

Monthly fee for plan A + The charge per minute ×  number of minutes of call for long distance for A = Monthly fee for plan B + The charge per minute ×  number of minutes of call for long distance calls for B

i.e $40.00 + $0.05 × n =  $15.00 + $0.10 × n

Or, $40.00 - $15.00 =  $0.10 × n -  $0.05 × n

Or, $25 =  $0.05 × n

∴ n = [tex]\dfrac{25}{0.05}[/tex]

I.e n = 500 minutes

So, The number of calls minutes = n = 500 minutes

Hence, The number of minutes of call for long distance is 500 minutes . Answer

The area of the rectangle will be 12b⁶ + 6b³ – 18b².

Let H be the height and W be the width of the rectangle. The area of the rectangle is the product of height and width.

Then the area of the rectangle will be

Area of the rectangle = H × W square units

A rectangle has a height of 3b² and a width of 4b⁴ + 2b – 6.

Then the area of the rectangle will be

Substitute H = 3b² and W = 4b⁴ + 2b – 6. Then the area of the rectangle will be

Area of the rectangle = 3b² x (4b⁴ + 2b – 6)

Simplify the equation, we have

Area of the rectangle = 3b² · 4b⁴ + 3b² · 2b – 3b² · 6

Area of the rectangle = 12b⁶ + 6b³ – 18b²

Thus, the area of the rectangle will be 12b⁶ + 6b³ – 18b².

The area of the rectangle is 0.75 of the square of the length. When the length is doubled, the width is 37.5 % of the length.

The area of a rectangle is calculated by multiplying its length and width. In this case, the width is 75% of the length. So if we denote the length as 'L', then the width would be 0.75 * L. Therefore, area would be L * 0.75L = 0.75 * L^2.

Now, if the length of the rectangle is doubled, the width remains the same, so it becomes 0.75 * 2L. So the width becomes a smaller fraction of the length. We can work out this out as follows: (0.75L / 2L) * 100 = 37.5%.

So, when the length of the rectangle is doubled, the width is 37.5 % of the length.

1. The area of the rectangle is 0.75 times the square of the length.

2. The width is now 75% of the length.

Part 1:

What is the area of the rectangle?

If the width of the rectangle is 75% of its length, then we can express the width as 0.75 * length.

The area of a rectangle is calculated by multiplying the length and width, so the area of the rectangle in this case is:

Area = length * width = length * 0.75 * length = 0.75 * length^2

Therefore, the area of the rectangle is 0.75 times the square of the length.

Part 2:

The length of the rectangle is doubled. What percent of the length is the width now? Explain your reasoning.

If the length of the rectangle is doubled, then the width is now half of 75% of the new length.

To calculate this, we can use the following steps:

Calculate the new length of the rectangle: old_length * 2 = new_length

Calculate 75% of the new length: 0.75 * new_length

Divide the width by the new length to get the percentage: width / new_length

For example, if the old length of the rectangle was 10 cm, then the new length would be 20 cm. 75% of 20 cm is 15 cm. Therefore, the width is now 75% of the length.

Answer: The width is now 75% of the length.

120+0.35=120.35

que tengas un buen día!!!!!!!!!!!!!

The initial amount of water in the tank was 1600 liters.

Let's denote the initial amount of water in the tank as W.

First, two-fifths of the water are used, leaving [tex]\(\frac{3}{5}\)[/tex] of the water remaining.

[tex]\[\text{Remaining amount} = \frac{3}{5} \times W\][/tex]

Then, three-quarters of the remaining water are used, leaving \(\frac{1}{4}\) of the remaining water.

[tex]\[\text{Final amount} = \frac{1}{4} \times \left(\frac{3}{5} \times W\right)\][/tex]

According to the problem, the final amount is 240 liters:

[tex]\[\frac{1}{4} \times \left(\frac{3}{5} \times W\right) = 240\][/tex]

Now, solve for W:

[tex]\[\frac{3}{5} \times W = 240 \times 4\][/tex]

[tex]\[\frac{3}{5} \times W = 960\][/tex]

[tex]\[W = \frac{960 \times 5}{3}\][/tex]

[tex]\[W = 1600\][/tex]

Step-by-step explanation:

TRUE, the student lunch price was generally increasing between 2000 and 2015 as the equation [tex]y=0.057x+1.150[/tex]  is a linearly increasing function.

TRUE, the student lunch price was changed by approximately [tex]5.7\rm cents[/tex]  a year.

FALSE, the student price in 2015 was approximately $1.15.

The best-fit line for the data has the equation  [tex]y=0.057x+1.150[/tex] , where [tex]x[/tex] is the number of years since 2000 and [tex]y[/tex]  is the student lunch price, in dollars.

So, it can be seen here from the best-fit line equation that it is a linearly increasing function so, the student lunch price was generally increasing between 2000 and 2015.

Now, differentiating the given best-fit line for the data has the equation  [tex]y=0.057x+1.150[/tex] with respect to [tex]x[/tex] to determine the approximated change of the lunch price per year

[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(0.057x+1.150)\\\dfrac{dy}{dx}=\$0.057\\\dfrac{dy}{dx}=5.7\rm cents[/tex]

And, [tex]2015[/tex] is [tex]15[/tex] years from the year [tex]2000[/tex] so, substitute the value of the parameter [tex]x=15[/tex] in the best-fit line equation, we get

[tex]y=0.057\times 15 +1.150\\y=0.855+1.150\\y=2.005[/tex]

Answer:

  Max is correct

  If one reflects a figure across the x-axis, the points of the image can be found using the pattern (x, y) ⇒ (x, –y).

  If one reflects a figure across the y-axis, the points of the image can be found using the pattern (x, y) ⇒ (–x, y).

  Taking the result from the first reflection (x, –y) and applying the second mapping rule will result in (–x, –y), not (y, x), which reflecting across the line should give.

Step-by-step explanation:

The answer above pretty well explains it.

The net result of the two reflections will be that any figure will retain its orientation (CW or CCW order of vertices). It is equivalent to a rotation by 180°. The single reflection across the line y=x will reverse the orientation (CW ⇔ CCW). They cannot be equivalent.

Max is correct in stating that two reflections, one across the x-axis and another across the y-axis, will not result in a reflection across the line y = x for a pre-image in quadrant II. Josiah's conjecture is incorrect. Statements that will help Max prove his conjecture include reflecting a figure across the x-axis and the y-axis, and how the coordinates of the image points change in each reflection.

Max is correct. When a figure is reflected across the x-axis, the y-coordinate of each point is negated, resulting in an image in a different quadrant. Therefore, reflecting a figure across the x-axis from quadrant II will place the image in quadrant III. Similarly, when a figure is reflected across the y-axis, the x-coordinate of each point is negated, resulting in an image in a different quadrant. Reflecting a figure across the y-axis from quadrant III will place the image in quadrant IV.

A figure that is reflected from quadrant II to quadrant IV will be reflected across the line y = x. However, reflecting a figure across the x-axis followed by a reflection across the y-axis will result in an image that is reflected across the line y = -x, not y = x. Therefore, Josiah's conjecture is incorrect.

The following statements will help Max prove his conjecture:

Therefore, Max's statements are correct and Josiah's conjecture is incorrect.

Step-by-step explanation:

Cost of 1 cellular bill = (number of text msgs per day) x (cost per text msg) x (number of days in billing period)

in this case, it is given that :

cost per text msg = $0.89

number of texts per day = 22 or 23

billing cycle = 6 weeks = 6 x 7 = 42 days

hence,

Cost of 1 cellular bill = (22 or 23) x $0.89 x 42 days

if she sends 22 messages,

Cost of 1 cellular bill = (22) x $0.89 x 42 days= $822.36

if she sends 23 messages,

Cost of 1 cellular bill = (2) x $0.89 x 42 days= $859.74

Answer:

The price per pound of apples is greater than $1.

Step-by-step explanation:

Please consider the complete question:

Three coworkers decided to buy fruit to share at lunch time. Antonii spent $1.47 on bananas.Laura spent $2.88 on apples. Suzanne spent $2.85 on oranges.   If Laura bought 2.1 pounds of apples, is the price per pound of apples greater than or less than $1 ? how can you tell?

To find the price of apples per pound, we need to divide total amount paid by Laura ($2.88) with total pounds of apples (2.1 pounds) bought.

[tex]\text{Price of apples per pound}=\frac{\$2.88}{2.1}[/tex]

[tex]\text{Price of apples per pound}=\$1.37142857[/tex]

Since the price of apples per pound is $1.37, therefore, the price per pound of apples is greater than $1.

We can simply tell that the price per pound of apples is greater than $1 because 2.88 is greater than 2.1. So when we will divide 2.88 by 2.1, then we will get a number greater than 1.

To find the price per pound of apples, we divide the total cost of the apples by the weight of the apples.

To determine whether the price per pound of apples is greater or less than $1, we need to divide the total cost of the apples by the weight of the apples. The question states that Laura bought 2.1 pounds of apples. To find the total cost, we can use the information given in the reference:

10 apples × 50 cents each = $5.00 spent on apples in 2001.

Dividing $5.00 by 2.1 pounds gives us the price per pound of apples Laura bought, which is approximately $2.38. Therefore, the price per pound of apples is greater than $1.
