rhe surface area of the 27 square of prism

i don’t know how to solve these can someone explain ?

Answers

the answer is 136 :)

first u should find the area of rectangular:

7 × 16 = 112

then u should find the area of triangular:

Altitude = 13- 7 = 6

base=16 - 8 = 8

so...u can find the area of triangular now:

(6× 8)÷2 = 48 ÷ 2 = 24

so...the area of your shape is: 112+ 24 = 136

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.

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

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)}

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
