The first Earth Day was observed on April 22, 1970. Since then, the week of April 22 has been Earth Week, a time for showing support for environmental causes. Fans Cafe is offering a reduced refill rate for soft drinks during Earth Week for anyone purchasing a Fans mug. The mug costs $2.95 filled with 16 ounces of soft drink. The refill price is $0.50. A 16-ounce drink in a disposable cup costs $0.85. What is the approximate break-even point for buying the mug and refills in comparison to buying soft drinks in disposable cups? a. (5, 7.8) c. (4, 6.7) b. (8, 0.5) d. (7, 5.95)
Let x specify the number of 16 ounce serving
If you buy the mug you acquire the first serving including the mug.
So the price of x is:
295 + 50(x - 1)
the x - 1 here shows that the first serving with the mug.
And then count the whole thing in cents.
The fee of throwaway cups is 85x
So breakeven is computed by:
295 + 50(x - 1) = 85x
295 + 50x - 50 = 85x
245 = 35x
x = 245/35 = 7
Checking this will give us:
mug 2.95 + 50*6 = 5.95
disposable
8.5*7 = 5.95
So the answer is D.
The break-even point occurs after nine soft drink purchases(8,0.5). Hence, the correct option is b.
First, let's consider the cost of the mug with a soft drink:
Mug + Soft drink = $2.95
Next, the cost of each refill:
Refill = $0.50
Then, the cost of a soft drink in a disposable cup:
Disposable cup soft drink = $0.85
To find the break-even point, let's set up the equation. Let x be the number of refills (including the initial drink from the mug):
Cost of mug with initial drink + (Cost per refill × number of refills) = Cost of disposable cup × number of drinks
2.95 + 0.50x = 0.85x
Now we solve for x:
2.95 = 0.85x - 0.50x
2.95 = 0.35x
x = 2.95 / 0.35
x = 8.43
Since we cannot have a fraction of a refill, we will round up to the nearest whole number. Therefore, the break-even point is after 9 refills (including the initial drink from the mug).
The approximate break-even point is after purchasing nine 16-ounce drinks. Therefore, the correct answer is (8, 0.5).

calculate the distance nathan rides his bike if he rides 9/12 mile each day for 3 days
Final answer:
Nathan rides a total distance of 2 1/4 miles when he rides 9/12 of a mile each day for 3 days. To calculate this, multiply the daily distance by the number of days and simplify the result.
Explanation:
To calculate the distance Nathan rides his bike if he rides 9/12 of a mile each day for 3 days, you need to multiply the distance he rides in a day by the number of days he rides.
Distance per day: 9/12 mileNumber of days: 3 daysSo, the total distance Nathan rides is:
9/12 mile/day × 3 days = 27/12 miles
To simplify the fraction:
Divide the numerator (27) and the denominator (12) by their greatest common divisor, which is 3.This gives us 9/4 miles.Convert 9/4 to a mixed number: 9 ÷ 4 = 2 with a remainder of 1, so it's 2 1/4 miles.Therefore, Nathan rides a total distance of 2 1/4 miles over the three days.
explain why the pattern for the products of 10s facts is a straight column.
You can use the fact that when staying in the same column and walking from row to row, there is addition of 10.
Why is there straight column for multiple of 10 in number counting having 10 columns?First choose a row. Since there are 10 columns per row, thus changing the row by choosing same column will give difference of 10.
Go down in rows on same column and you'll see increment of 10, and go up in rows with same column and you'll see decrement of 10.
]This is the key reason behind that straight columns of multiples of 10s.
Let the number be x
Then moving from row to row on the same column, we will get:
x, x + 10, x + 20, x + 30, ...
If x = 10, we get 10, 20, 30, 40 which are multiples of 10 since
[tex]10 + 10 = 10 \times 2\\10 + 20 = 10 \times 3\\...\\ 10 + 10y = 10 \times (y+1)[/tex]
See the given table below:
[tex]\begin{array}{cccc}\cdots&x&\cdots & 10\\\cdots & x + 10 & \cdots & 10 + 10 = 10 \times 2 = 20\\\cdots & x+ 10 + 10 = x + 20 & \cdots & 20 + 10 = 10 \times 2 + 10 = 10 \times 3 = 30\\\cdots & \cdots & \cdots & \cdots\end{array}[/tex]
The last column, therefore, has multiples of 10 since adding 10 for multiple of 10 is like multiplying 10 by one bigger number which is same as increasing multiples of 10.

A deck of cards has three yellow cards and five green cards. One green card is drawn from the deck and not replaced. One more card is random drawn. Find the probability that the second card is yellow.
3/8
3/7
15/56
The probability that the second card is yellow after one green card is drawn and not replaced from a deck of 8 (3 yellow, 5 green) cards is 3/7. The correct answer is option b) 3/7.
To find the probability that the second card is yellow after drawing one green card (and not replacing it), we can follow these steps:
Determine the total number of cards in the deck after the first green card is drawn. Initially, we have 3 yellow + 5 green = 8 cards. After drawing one green card, there are 7 cards left (2 yellow and 5 green).Since one green card is drawn and not replaced, the number of green cards that remain in the deck is now 4, and the total number of cards left in the deck is 7.Calculate the probability of drawing a yellow card from the remaining 7 cards. There are still 3 yellow cards, so the probability is 3 yellow cards divided by the 7 total remaining cards.Thus, the probability that the second card is yellow is 3/7, which is corresponding to (b).

Which tax bracket a person Falls into is determined by his or her ?
A. Salary
B. Taxable income
C. AGI
D.Gross income
Answer:
B. Taxable income
Step-by-step explanation:
Taxable income is the amount of money that a person earns in a period of time that can be taxated by the government, you could earn money that is not taxated, for example life insurances from deceased family members is not taxable, also upto a certain amount of money as a gift is not taxable. So the tax bracket a person falls into depends solely on the taxable income that they make in a year.
Final answer:
B: Taxable income
A person's tax bracket is determined by their taxable income, which is their adjusted gross income minus any deductions and exemptions.
Explanation:
The tax bracket into which a person falls is determined by his or her taxable income.
Taxable income is the amount of income that is subject to the official tax rates for each bracket.
This figure is the result of subtracting deductions and exemptions from your adjusted gross income (AGI). It's important to note that taxable income and AGI are not the same, as the latter is your income from various sources minus specific adjustments but before deductions and exemptions.
To calculate taxable income, the equation used is: taxable income = adjusted gross income - (deductions + exemptions).
Income Tax Brackets are the thresholds of income that are taxed at varying rates. As an individual’s taxable income increases, not only does the amount of tax paid increase, but typically so does the percentage of tax on additional income, as the tax rates in higher brackets are usually higher.

Write the equation in standard form for the circle passing through ( - 1,3) centered at the origin.
Final answer:
The standard form equation of a circle centered at the origin and passing through (-1,3) is x² + y² = 10, where √10 is the radius of the circle calculated using the distance formula.
Explanation:
To write the equation of a circle in standard form that is centered at the origin and passes through the point (-1,3), you first need to calculate the radius using the distance formula. The distance formula is √((x2-x1)² + (y2-y1)²), where (x1, y1) is a point on the circle and (x2, y2) is the center of the circle. Since the circle is centered at the origin, (0,0), we can compute the radius as follows:
Radius = √((-1 - 0)² + (3 - 0)²) = √(1 + 9) = √10
The standard form of the equation for a circle centered at (h, k) with a radius r is:
(x - h)² + (y - k)² = r²
Since our circle is centered at the origin, h = 0 and k = 0, and the radius r = √10, the equation becomes:
x² + y² = 10

Yul left the class at 11:55 A.M. after it ended, having added 30 minutes to the start time. Sarah stayed for an extra 5 minutes, which implies she departed at 12:00 P.M.
Yul and Sarah's art class started at 11:25 A.M. and it lasted 30 minutes. To find out when Yul left, we simply add 30 minutes to the starting time. Starting at 11:25 A.M., after 30 minutes, it will be 11:55 A.M. That's when Yul left the class.
Sarah stayed an additional 5 minutes after the class to talk with the teacher. So, we add those 5 minutes to the time Yul left, which was 11:55 A.M. If we add 5 minutes to 11:55 A.M., it becomes 12:00 P.M. Therefore, Sarah left the class at noon.
