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 1

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.

Can someone explain to me how I can eliminate one of the variables to solve this equation for one of the variables?

Answers

Answer:

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer:

x = 1 and y = 4

Step-by-step explanation:

Multiply the top equation by 7 on both sides, and then cancel it out:

7(5x + y) = 7(9)

35x + 7y = 63

Now use this equation to cancel out -7y on the second equation:

35x + 7y = 63

10x - 7y = -18

45x = 45

x = 1

Now that we have our x-value, we can plug it into one of our two original equations:

5(1) + y = 9

y = 4

Micheal is buying Presents for a gift exchange for his four friends. He would like to spend less than $160 total. On average, how much can he spend on each person? Write out the Inequality as well.

Answers

Answer:

Micheal will spent 40 $ on each of his friends

Step-by-step explanation:

160$÷4=40$

why because there is 160 dollars to spend and there are 4 friends now you need to divide that to get the amount of money you need.

Answer:

x≤40. He can spend about $40 on each friend

Step-by-step explanation:

I got this because a number x is the amount of money he can spend on a friend on average. The inequality is then written like 4x≤160. You then try to get "x" on its own by dividing both sides by 4 (both sides being 4x and 160). then you get the average amount Michael can spend on his friends.

Help! Giving brainliest and 10+ points, A ball is dropped from the top of a 400-ft tall tower. The relationship between the time, t, in seconds, and the height, h(t), in feet, of the ball can be modeled by a quadratic function. Specific values of the function are shown in the table below
Part A: Determine the average rate of change of h(t) between t = 2 and t = 5.
Part B:Explain what this average rate of change means in terms of the context.

Answers

The average rate of change of h(t) between t = 2 and t = 5 is -112. See the explanation below.

What does this average rate of change means in terms of the context?

Because the average rate of change is negative it simply means that the slope of the Quadratic function is also negative.

What is the calculation showing the above answer in part A?

We are given the following:

When t =2; h(2) = 336

When t = 5; h(5) = 0

Recall that the Average Rate of Change on the interval [a,b] is given as:

[ta - tb]/(b-a)

Since the state interval is [2,5]; and

h(2) = 336; and

h(5) = 0

Hence

ARC = 0-336/5-2

= -336/3

= -112

Where was his tea, he wondered? He looked around to see whether the servants were arriving with the longed-for cup of steaming liquid. Dipping his fingers languidly into the cool pond, he delicately plucked out an oval-shaped purple leaf with fine-toothed edges, then let it drop so he could capture a newer one, a larger, brilliantly red leaf whose crinkled surface curled like the palm of a hand. Behind him, at the edge of the wide, sloping lawn, the tall, green fronds of bamboo waved, as mild as grazing sheep, and the politely clicking melody of wooden wind chimes wafted from the weathered pine balcony of his twelve-bedroom cottage. He would write a poem, he decided, for the leaf-watching festival, the Emperors favorite week of the year. A poem, perhaps about the bare slopes of Mount Atu, and a lone climber struggling up the mountainside as a late spring snow began to cover his shoulders. I am that climber, he thought, remembering the recent power struggles at the palace.All the nobles and royals of the court would be present at the poetry reading contest, returning from their summer retreats to begin the excitement of the new social season. Cranes would fly picturesquely across the face of the full moon; toy paper boats carrying small-flamed candles would drift like glad-eyed children on the palaces artificial lake. Sighing with expectation, the prince inhaled deeply the thin, tickling tang of pine-needle incense. Yes, the Emperor would approve of his poem, and perhaps grant him an honor such as the green sash of the Keeper of the Park! Our civilization, the prince thought, has reached a glorious peak.How does this passage convey a sense of the time during which the scene occurs?It specifies that the poem will be about a late spring snow.It mentions a full moon, cranes, and toy boats floating on a stream.It shows the prince's thoughts about certain events.It describes objects in nature that indicate the season. ***98 POINTS *** someone please help Dario is finding the percent of change from the original price of $75 to new price of $125. what is the range of possible sizes for x?
