Step-by-step explanation:

Megan wants to give each guest at her birthday party three mini-
cans of Play-Doh. The cans are sold in bags of nine for $2.86. If there
are thirty-six guests at her party, how much will it cost to give three
mini-cans of Play-Doh to each guest?

Answers

36 x 3 = 108 so you need 108 cans of mini play dough. 108 divided by 9 is 12 so you need 12 bags. 12 x 2.86 is 34.32. It will cost $34.32 to buy 108 cans of mini play dough and give 3 to each of your 36 guests

Number of guests to be invited in the birthday party = 36

Megan wants to given 3 cans of Pay-Doh to each guest.

Therefore, number of cans to be given = 3 × 36 = 108

Since, cans are sold in the pack of 9, number of packs required = [tex]\frac{108}{9}[/tex]

                                                                                                           = 12

Since, cost of each pack of cans = $2.86

Therefore, total cost of 12 packs = 12 × 2.86

                                                       = 34.32

Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.

Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct? Explain your thinking.

Answers

Answer:

She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.

Step-by-step explanation:

You have a deck of cards and draw three cards one after the other without replacing the cards. What is the probabilities of drawing three tens? (Pls give a good explanation & the answer lol)

Answers

Answer:

The probability of drawing 3 tens one after another without replacing them is 1/5525

Step-by-step explanation:

In a pack of 52 cards, there are 4 cards that are 10, so the probability of drawing one ten [p(10)] = 4/52

Therefore:

The first draw, P(10) = 4/52  

Now, at this point you have taken out one of the cards with a number 10 printed on it, so we are left with 51 cards in total and 3 cards of 10.

The second draw, p(10) = 3/51

Now, we have 50 cards left and a total of 2 cards with a number 10 printed on it.

The third draw, p(10) = 2/50

Hence, the probability of drawing out 3 number 10 cards without replacement is:

4/52 * 3/51 * 2/50 = 1/5525  

The probability of drawing 3 tens one after another without replacing them should be 1/5525.

Calculation of the probability:

Since  we know that

In a pack, there are 52 cards and there are 4 cards that are 10,

so the probability of drawing one ten [p(10)] = 4/52

Now it should be left with 51 cards in total and 3 cards of 10.

So, The second draw, p(10) = 3/51  

and, The third draw, p(10) = 2/ 50

Thus,  the total probability is

= 4/52 * 3/51 * 2/50

= 1/5525

The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Show all work to receive full credit.

A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)

Answers

Answer:

Answer Below

Step-by-step explanation:

The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?

a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:

Circumference = 2π × radius; but diameter = 2 × radius. Hence:

Circumference = π * diameter.

Given that diameter of the tire = 2.5 ft:

Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft

b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.

1 mile = 5280 ft

The number of rotation required to cover 1 mile (5280 ft) is:

number of rotation = 5280 ft/7.85 ft per rotation = 672 rotations.

I need a set of coordinates to model a relation that is a linear function quick please.

Answers

Answer:

y=2x+1

Step-by-step explanation:

The linear function is a function that has a straight line graph.

Response:

A set of coordinate that model a linear function is presented as follows;

{(0, 5), (1, 8), (2, 11), (3, 14), (4, 17), (5, 20)}

Method by which the above set of coordinates is obtained

A linear function is a function that can be written in the form; y = m·x + c

Where;

m = The slope of the graph is a constant

c = The y-intercept of the graph is a constant

Therefore,

Therefore, a set of coordinates can be obtained by setting the values of m and c as follows;

When m = 3, and c = 5, we have;

y = 3·x + 5

Using the above equation, we get;

[tex]\begin{tabular}{|c|c|} \underline{x} & \underline{y = 3 \cdot x + 5}\\0&5\\1&8\\2&11 \\3&14\\4&17\\5&20\end{array}\right][/tex]

Using the above table of values, a set of coordinates that model a linear function is therefore;

{(0, 5), (1, 8), (2, 11), (3, 14), (4, 17), (5, 20)}

8%. How much will William pay in interest on this loan?

Answers

Answer:

Step-by-step explanation:

I'm going to assume two things

The interest rate is compoudning annually

There is only one payment (at the end of the 10 years)

To find the amount of interest paid on this loan we first need to calculate the future value (or accumulated value)

FV=PV(1+i)^n

Plug in our numbers

2500(1+.08)^10

Run this through a calcuatlor and get 5,397.31

This is the future value and the question is asking for the interest paid which is just the FV-PV
