Answer:
to serve hot chocolate to 14 people, you need:
7/6 cups boiling water
12.25 cups milk
2 5/8 teaspoons vanilla
7/4 half & half cream
To serve cookies to 14 people you need:
2.4 (rounded) cups flour
7/8 teaspoon baking soda
7/16 teaspoon baking powder
7/8 cup butter
21/16 cups white sugar
Step-by-step explanation:
The regular recipe for hot chocolate serves 4 people. But 14 are being served; 14 is 3.5 times as much as 4, so multiply the measurements by 3.5.
The recipe for cookies makes 16 servings of 3 cookies (4 dozen total), so you must use slightly smaller quantities. 14 is 7/8 as much as 16, so just multiply the measurements by 7/8.

Please help, I need help on this math question
Answer:
Probably C
Step-by-step explanation:
Repeating Decimal: a decimal where a number or a pattern of numbers repeats forever
For example, 0.2222... or 0.671671.... (The "..." means that it repeats like that forever)
A. 3/7= 0.142857142857142857... (6 repeating digits) This is a repeating decimal because the last six digits continue forever
B. 3/4=0.75. This number is not a repeating decimal because a repeating decimal goes on forever, while this only has two decimal places.
C. 1/9= 0.11111... This is a repeating decimal because it goes on forever and has a pattern (all are 1s)
D. 5/11=0.454545... This is also a repeating decimal because the last two digits repeat forever.
There is probably something wrong with the question (or your unit) because three of these numbers are, in fact, repeating decimals. If I were you, I would ask your teacher (it gets you respect from the teacher=more chance that they'll be lenient with you)
But if you really don't want to, I would go with "C" because it only has one repeating decimal place, and your curriculum probably says that a repeating decimal is only one digit.
Good Luck! :)

1. The school office is now selling neon mechanical pencils. If the office pays $10.80 for a dozen pencils, how much should be charged to make a profit of 75 cents each?
2. Several cases of 16-ounce bottles of water were purchased for $252.00. If one case costs $7.00, how many cases were purchased?
3. Okolona College ordered jerseys to sell at the homecoming game. The college paid $9.25 each for 225 jerseys. Each jersey was sold for $15.75. What was the percent of markup for each jersey? How much profit was made if all of the jerseys were sold?
4. A truck traveled 654 miles on a long distance run. If the truck averaged 55 mph, how many hours did it take to reach the truck's destination? (Round to the nearest hour)
5. Della Riley borrowed $2400 for 6 months to invest in a business venture. If she agreed to pay 8% interest annually, how much will she be repaying?
6. It takes Dan an average of 45 minutes each evening to do his chemistry homework. Dan calculates that he worked a total of 3 hours on chemistry last week. Assuming that Dan worked his average time per evening consistently, how many evenings did Dan work?
7. Jon's car averages 20 mpg in town and 28 mpg on the road. What is the percent of decrease between the two driving conditions?
Answers:
1)10.80/12 =0.90
0.90+0.75=1.65
2)252/7=36 units
3)cost price = $9.25*225
= $2081.25
Selling price = $15.75*225
= $3543.75
Profit = Selling price - cost price
Profit = $3543.75 - $2081.25
=$1462.50
5) FV = L*(1 + rt),
Where FV is the amount to repay; L is the borrowed amount (the loan amount) and "r" is the annual interest as decimal; t is the time.
In your case L = 2400 dollars; r = 8% = 0.08 (as decimal) and t = 0.5 of a year (6 months).
Therefore,
FV = 2400*(1 + 0.08*0.5) = 2496.
In 6 months, Della Rilley must repay $2496
4) 654miles/55mph=11 hours, 53 minutes, 27 seconds ANS: ap.12 hours
time = distance/speed
6) 60*3=180mins
180/45=4
Ans: 4 days
7) This is a decrease of 8
a decrease of 28.57% rounded to two decimals
Ellena knows that 1/5 written as a decimal is 0.2. How can Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5?
The decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5
How to convert from decimal to fraction?For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.
WE are given that Ellena knows that 1/5 written as a decimal is 0.2.
Thus Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5
By multiplying 0.2 by 9 we can get the decimal equivalent of 9/5.
0.2 x 9 = 4.5
Hence, the decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5

A cardboard box has a volume that is 6,336 cubic inches. A company creates a new design with the same proportions, but instead the dimensions are One-fourth the dimensions. Explain how you can find the volume of the new design without knowing the dimensions.
Answer:
Cube the scale factor 0.25. Then multiply the volume of the box by 0.015625.
Answer:
Since the dimensions have a proportional relationship, the new volume can be calculated using the original volume and the scale factor. The new volume will be the cube of the change, which is 1

Consider the two functions below. Which one of these functions is linear? What is its equation? Enter any answers to two decimal places.
Answer:
Function A and the equation would be y = 1.6666666666~x + 0
Step-by-step explanation:
A linear function is a function that is a straight line with no change so function B does not fit that description. So than it has to be A
To find the equation you first what to find the slope of the line
ΔY/ΔX = 5/3 = 1.666666666666
Take the slope and multiply it by x to get y
Following are the solution to the given function:
Given:
Function A:
[tex]\bold{x} \ 3 \ 6 \ 9 \ 12 \ 15 \\\\\bold{y} \ 5 \ 10 \ 15 \ 20 \ 25[/tex]
To find:
Find the function=?
Solution:
Function A or equation would've been [tex]\bold{y = 1.6666666666 \sim x + 0}[/tex].The linear equation is a straight line with really no modification, hence function B doesn't suit its description. As a result, it has to be A.You must first calculate the slope of the line to solve this equation.[tex]\bold{\to \frac{\Delta Y}{ \Delta X} = 5/3 = 1.666666666666}[/tex]To get y, take the slope then multiply this by x.Bree takes 4.75 minutes to bike around the block how long does it take Bree to bike 11 times around the block?
