phone store makes $15 per hour plus a commission
cales This week she sold 40 phones averaging $450
4. An employee at a cell phone store makes $15
of 2.5% of her phone sales. This week she sold
each. What is her commission this week?

(i need the explanation)

Answers

450 multiplied by .025 also known as 2.5 percent which equals 11.25 dollars
which is her commission for the week
Final answer:

An employee at a cell phone store sold 40 phones for $450 each, totaling $18,000 in sales. Based on her commission rate of 2.5%, she earns $450 in commission for the week.

Explanation:

The subject of this question is how to calculate the employee's commission based on her sales. First, we need to calculate the total sales the employee made. She sold 40 phones at $450 each, so her total sales would be 40 * $450 = $18,000.

Next, we need to figure out what 2.5% of her total sales is because this is her commission rate. The calculation would be $18,000 * 2.5/100 = $450.

So, the employee's commission for this week is $450.

the volume is everything on the inside of the tank

surface area would only be the amount of water it take of cover one side

area would just be the size of the glass on bottom

the perimeter would just be the length of all four edges of each side of the fish tank

For the maximum amount of water it takes to fill a rectangular fish tank, we need to know the volume of the fish tank.

Option A is the correct answer.

What is a rectangle?

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

The volume of any container gives us the maximum amount the container can hold.

What is coordinate geometry?

Coordinate geometry is the study of geometry using the points in space.

On a coordinate plane, the x-axis is labeled Side length and the y-axis is labeled Perimeter or area.

A line representing the perimeter goes through points (0, 0), (1, 4), (2, 8), (3, 12).

Then the equation of line will be

y = [(12 – 8) / (3 – 2)]x

y = 4x

A curved line representing the area goes through points (0, 0), (2, 4), (3, 9), and (4, 16).

y = x²

Andrew wants to build a square garden, and needs to determine how much area he has for planting.

The perimeter of the garden is between 12 and 14 feet.

Then the value of the side length corresponding to 12 and 14 will be

For y = 12, we have

12 = 4x

 x = 3

Then the area will be

y = 3²

y = 9 square feet

For y = 14, we have

14= 4x

 x = 3.5

Then the area will be

y = 3.5²

y = 12.25 square feet

Then the range of the possible areas will be 9 square feet and 12.25 square feet.

Kayla wants to purchase some new clothes for the school year and has a budget of $200. The sales tax rate that will apply when she makes her purchases is 7%. Here are the items she wants to purchase:

2 T-shirts, $9.98 each
1 pair of pants, $25.99
3 dresses, $24.99 each
1 pair of shoes, $89.99
Kayla’s budget be enough to purchase all of the clothing items listed after sales tax is applied because the total will be .

Answers

Answer:

Kayla will not have enough because the total will be $225.67

Step-by-step explanation:

2 * 9.98 = 19.96

3 * 24.99 = 74.97

19.96 + 25.99 = 45.95

45.95 + 74.97 = 120.92

120.92 + 89.99 = 210.91

0.07 * 210.91 = 14.76

210.91 + 14.76 = 225.67

Kayla will not have enough because the total will be $225.67

Calculation of the total balance:

Since there is a budget of $200. The sales tax rate is 7%

Also, the following items should be purchased

2 T-shirts, $9.98 each

1 pair of pants, $25.99

3 dresses, $24.99 each

1 pair of shoes, $89.99

So, the calculations should be

2 of 9.98 = 19.96

3 of 24.99 = 74.97

Now the total should be

19.96 + 25.99 = 45.95

45.95 + 74.97 = 120.92

120.92 + 89.99 = 210.91

0.07 of 210.91 = 14.76

And, finally

210.91 + 14.76 = 225.67

Therefore, Kayla will not have enough because the total will be $225.67

Melissa is saving $25 that she earned for washing her mom’s car. She earns $10 every week for doing chores, which she also saves. Which function can be used to find t, the amount of money Melissa will have saved at the end of n weeks of doing chores?

Answers

Answer:

t = 10n + 25

Step-by-step explanation:

At the end of n weeks, the total amount that Melissa would have can be found by the function, t = 25 + 10n.

Melissa made $25 from washing her mother's car and keeps it aside.

She then makes $10 every week. This means that in n number of weeks, the amount she would have made from chores is:

= Amount per week x number of weeks

= 10 x n

= 10n

The total she would then have in n weeks is:

= Amount saved from mother + Amount earned from chores in n weeks

= 25 + 10n

This total is t, so the total function is t = 25 + 10n.

a. 1/7

b. 8/14

c. 2/14

d. 1/14

Answers

Answer: D) 1/14

Work Shown:

There is 1 orange marble out of 7 total. The probability of picking an orange marble is 1/7. Let A = 1/7 which we'll use later.

The probability of flipping tails is 1/2 because 1 side is tails out of 2 sides total. Let B = 1/2

Multiply A and B

A*B = (1/7)*(1/2) = (1*1)/(7*2) = 1/14

This represents the probability of getting an orange marble and flipping tails.

We are able to multiply the probabilities because the two events (picking a marble and flipping a coin) are independent.

Part C: YX = 24 meters and mYX = 120 degrees , then determine the radius of circle H.

Answers

Answer: The radius is 11.5 meters (to the nearest tenth)

Step-by-step explanation: The circle with center H has an arc TX that measures 24 meters, and also the angle subtended by YX equals 120°.

The length of an arc is given b the formula;

Length of arc = (∅/360) x 2πr

Where the length of the arc is 24 and ∅ is 120, the formula becomes;

24 = (120/360) x 2(3.14) r

24 = (1/3) x 6.28 r

By cross multiplication we now have,

(24 x 3)/6.28 = r

72/6.28 = r

11.4649 = r

r ≈ 11.5

Therefore, the radius is approximately 11.5 meters

You have a $500 public relations budget for the current year. You would like to generate publicity by publishing several ads in the local township newspaper about your store's sponsorship of community activities. The newspaper normally charges $75 per ad but will give you a 20% discount since your message is community service-oriented. How many ads can you buy?

Answers

Answer:

8 ads

Step-by-step explanation:

To start off, we know we have a budget of $500 which means we cannot go above that amount. Ads cost $75 each but in our case they are now 20% cheaper. Lets figure out the new price of the ads. Remember to change 20% into its decimal form (20% -> 0.2)

75 x 0.2 = 15

Now we subtract 15 from 75 to get our new ad price.

75 - 15 = 60

Now to figure out how many ads we can get with a budget of $500, we simply divide 500 by 60. Don't forget to round the answer to the nearest whole number since we cannot go over our budget.

500 / 60 = 8 ads

Answers

The measure of angle VU is 240°.

Given that arc SV has a measure of **120°** and angle STV is **82°**, we can find the measure of angle VU.

1. The central angle STV is equal to the measure of arc SV. Therefore, ∠STV = 120°.

2. The sum of angles around a point (360°) is equal to the sum of the central angle and the inscribed angle. So, ∠VU + ∠STV = 360°.

3. Solving for ∠VU:

  - ∠VU + 120° = 360°

  - ∠VU = 360° - 120°

  - ∠VU = 240°

Therefore, the measure of angle VU is 240°.

A 2-m3 rigid tank initially contains air at 100 kPa and 22C. The tank is connected to a supply line through a valve. Air is flowing in the supply line at 600 kPa and 22C. The valve is opened, and air is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. A thermometer placed in the tank indicates that the air temperature at the final state is 77C. 1) Starting with the most general form of the appropriate mass balance equation, determine the mass of air that has entered the tank (4 points). 2) Starting with the most general form of the appropriate energy balance equation, determine the amount of heat transferred and whether it was heat transferred in or out (8 points). 3) List at least 3 assumptions needed to complete this problem (3 points). science: what are atoms where can they be found?
