Tracy has a cell phone plan that provides 250 free minutes each month for a flat rate of 29$. For any minutes over 250 tracy us charged 0.35$ per minute. Which of the following picewise functions represents charges based on tracy’s cell phone plane?

Answers

Answer 1

The answer choices are where....?

Answer 2

The piecewise function representing Tracy's cell phone charges is C(m) = {29 if m ≤ 250, 29 + (0.35)(m - 250) if m > 250.}.

Based on Tracy's cell phone plan, we want to create a piecewise function that represents the charges based on her usage. She is offered 250 free minutes at a flat rate, and any additional minutes are billed at an additional rate per minute. This piecewise function will have two parts: one for when Tracy's usage is at or below 250 minutes, and another for when her usage exceeds 250 minutes.

The first part of the function accounts for the flat rate up to 250 minutes:

If m ≤ 250, then C(m) = 29.

The second part of the function accounts for additional charges past 250 minutes:

If m > 250, then C(m) = 29 + (m - 250) * 0.35.

Therefore, the piecewise function that represents Tracy's cell phone charges based on the minutes used (m) is:

C(m) = {
29 if m ≤ 250,
29 + (0.35)(m - 250) if m > 250.
}

Answers

Your anniversary is usually when you are given a job review and possible increase in pay by a company. Most companies will review your performance for the past year and offer an increase in pay due to yearly inflation, or cost of living.

Answer: Option 'B' is correct.

Step-by-step explanation:

Your anniversary is usually when you are given a job review and possible increase in pay.

As in a job, job review is given at the time of anniversary, then on the basis of their performance there may be increase in pay.

Emma likes to knit hats and mittens for friends and family. Last fall, she knitted 4 hats and 3 pairs of mittens, which took a total of 46 hours. This fall, she knitted 2 hats and 1 pair of mittens, which took a total of 18 hours. If each hat and each pair of mittens takes the same amount of time to knit, how long does it take Emma to knit a hat and a pair of mittens?

Answers

Final answer:

Emma takes 4 hours to knit a hat and 10 hours to knit a pair of mittens, which was determined by solving two linear equations based on the time she spent knitting during two different falls.

Explanation:

Emma likes to knit hats and mittens, and we need to find out how long it takes her to knit a hat and a pair of mittens individually. Given that last fall she knitted 4 hats and 3 pairs of mittens in 46 hours, and this fall she knitted 2 hats and 1 pair of mittens in 18 hours, we can set up two equations to solve for the time it takes to knit each item.

Let's define H as the number of hours it takes to knit one hat and M as the number of hours it takes to knit one pair of mittens. The equations based on the given information are:

4H + 3M = 46 (Last fall's knitting)

2H + 1M = 18 (This fall's knitting)

To solve these equations, multiply the second equation by 2 to align the hats:

2(2H + 1M) = 2(18)

4H + 2M = 36

Now subtract this equation from the first equation to find M:

4H + 3M - (4H + 2M) = 46 - 36

M = 10

Substituting M back into the second original equation:

2H + 1(10) = 18

2H = 8

H = 4

Emma takes 4 hours to knit a hat and 10 hours to knit a pair of mittens.

choose the most appropriate strategy and then use it to solve the quadratic equation.

Angela spent $30.00 at a resturaunt. if she leaves a 15% tip, how much wll her total bill be

Answers

Answer: Her total bill will be: " $34.50 " .
_____________________________________________________
Explanation:
_____________________________________________________
15% = 15/100 = 15 ÷ 100 = 0.15 .

$30 + {0.15 * $30} = $30 + ($4.50) = " $34.50 " .
_____________________________________________________

Note: "15% of $30 = (0.15 * $30) = $4.50 .

We add the "$4.50" tip to the $30.00 that is spent; to get: " $34.50 " .
_____________________________________________________

Final answer:

Angela's total restaurant bill, after adding a 15% tip to her $30.00 original charge, will be $34.50.

Explanation:

To find out how much Angela's total bill will be after leaving a 15% tip at a restaurant, you first need to calculate the tip amount and then add it to the original bill. You calculate the tip by converting the percentage to a decimal and then multiplying by the cost of the meal. In this case, 15% of $30.00 is found by multiplying $30.00 by 0.15 which gives you $4.50. After calculating the tip amount, add it to the original bill to get the total amount Angela will pay.

Tip: $30.00 * 0.15 = $4.50.

Total bill: $30.00 + $4.50 = $34.50.

Therefore, Angela's total bill, including the 15% tip, will be $34.50.

Answers

sorry fam im stumped hope you get the answer your looking for

Answer with explanation:

The Vertices of quadrilateral A B CD, are A(1, a - 3), B(10, a), C(9, a + 3) and D(0, a).

Mid point of AC= (5,1)

Mid point of B D= (5,1)

Mid point formula of two points having coordinates , (a,b) and (c,d) is , if (x,y), then

[tex]x=\frac{a+b}{2},y=\frac{c+d}{2}[/tex]

[tex]So,\rightarrow \frac{a-3+a+3}{2}=1\\\\\rightarrow \frac{2a}{2}=1\\\\\rightarrow a=1[/tex]

So, the coordinates of vertices of quadrilateral A B CD, are A(1, -2), B(10, 1), C(9, 4) and D(0, 1).

Distance formula of two points having coordinates, (a,b) and (c,d) is,

[tex]=\sqrt{(a-c)^2+(b-d)^2}[/tex]

[tex]AB=\sqrt{(10-1)^2+(1+2)^2}=\sqrt{81+9}=\sqrt{90}=3\sqrt{10}\\\\BC=\sqrt{(10-9)^2+(1-4)^2}\\\\=\sqrt{1+9}\\\\=\sqrt{10}\\\\CD=\sqrt{(9-0)^2+(3-0)^2}=\sqrt{90}=3\sqrt{10}\\\\DA=\sqrt{(1-0)^2+(1+2)^2}=\sqrt{10}\\\\AC=\sqrt{(9-1)^2+(4+2)^2}=\sqrt{64+36}\\\\AC=\sqrt{100}\\\\AC=10\\\\BD=\sqrt{(10-0)^2+(1-1)^2}\\\\BD=10[/tex]

Opposite sides AB and CD are equal to 3√10 unit and , BC and AD are equal to √10 unit.

Also,length of Diagonals , AC=B D=10 unit.

∴ The Quadrilateral, AB CD is a Rectangle.

The volume of a sphere is given by the equation [tex]V= \frac{4}{3} \pi r^3[/tex], where r is the radius.

We are given the diameter of the sphere, but recall that the diameter is twice the radius: [tex]d=2r[/tex]. So the radius is half of the diameter: [tex]r= \frac{1}{2}d[/tex].

Half of 8 cm is 4 cm.

We substitute this for r in the equation and we use 3.14 for π.

[tex]V= \frac{4}{3}(3.14)(4)^3= \frac{(4^4)(3.14)}{3}=267.9 \ cm^3 [/tex]

the steps for this are below

recall volume of sphere formula is

Large Cheese Pizza $14.85
Large Supreme Pizza $16.90
Cheese Sticks $5.99
Dessert Pizza $6.99

4. The largest order last Saturday was from a basketball team that ordered 5 large supreme pizzas, 5 large cheese pizzas, 5 orders of cheese sticks and 5 dessert pizzas. Jacob said the total was about $225. Is this reasonable? Justify your response using estimation. If the answer is not reasonable, identify the error and then calculate the correct solution.

Answers

this is reasonable, the total of everything would be 223.65.. which rounds up to 225.

Jacob's estimate of $225 for the basketball team's order is reasonable. Our calculations show a total estimated cost of $223.75, which is close to Jacob's estimate.

To determine if Jacob's estimated total of $225 for the basketball team's order is reasonable, we can perform a quick estimation.

First, let's list the items ordered:

5 large supreme pizzas at $16.90 each5 large cheese pizzas at $14.85 each5 orders of cheese sticks at $5.99 each5 dessert pizzas at $6.99 each

Next, we will estimate the total cost for each category:

5 large supreme pizzas: $16.90 x 5 = approximately $84.505 large cheese pizzas: $14.85 x 5 = approximately $74.255 cheese sticks: $5.99 x 5 = approximately $305 dessert pizzas: $6.99 x 5 = approximately $35

Now, summing these estimates: $84.50 + $74.25 + $30 + $35 = $223.75

Thus, Jacob's estimate of about $225 is reasonable, as our estimation shows a total of $223.75, which is close to his figure.

Rudy collects baseball cards, and he currently has 300 cards. Starting tomorrow, he will purchase 1 pack of 15 baseball cards every day, and every pack he purchases will contain 1 card of a member of his brother???s favorite team. Every time Rudy purchases a pack of cards, he will immediately trade the card of the member of his brother???s favorite team to his brother for 3 cards of members of a different team. Which of these recursive formulas produces the sequence that represents the number of baseball cards that Rudy will have at the end of each day, starting today?

Answers

Answer: The equation to find the number of cards could be: c = 300 + 17d, where c equals the total number of cards and d represents the number of days.

The 300 value is the starting amount of cards that Rudy has.

The 17 represents the number of cards that he is getting per day. It started at 15 because that is the amount in a pack of cards. However, he trades one to his brother and gets 3 in return.

15 - 1 + 3 = 17 extra cards per day
