In the morning, Marco sold 12 cups of lemonade for $3. By the end of the day, he had earned $9. How many cups of lemonade did he sell in all?
STEP BY STEP ANSWER don't use me for points
Kaycee wrote the proportion 12/3= 9/c Identify the error and give two ways to write the proportion correctly.
Answers
Answer:
2
Step-by-step explanation:
only made $9 so one cup is $3 so two cups equal $9
Answer:
Sample response: Kaycee did not keep lemonade and dollars in corresponding positions in the ratios of the proportion. The proportion should be 12/3=c/9 or it could be written 3/12=9/c. Dollars should be in the same position and cups should be in the same position across ratios.

Simplify the expression: 4(x+3)+3(5−x)
x + 27
x +8
2x + 15
19x + 11
Answers
Answer:
A. x + 27
Step-by-step explanation:
4(x+3)+3(5−x)
4x + 12 + 15 - 3x
x + 27
First multiply each of the brackets by the number on the outside:
4(x + 3) = 4x + 12
3(5 - x) = 15 - 3x
Then add these into the expression:
4x + 12 + 15 - 3x
Collect the like terms (the things that have the same letters):
4x - 3x = 1x (but remember we don’t write the 1, so it’d just be x)
12 + 15 = 27
Therefore:
x + 27
Your answer would be:
A) x + 27
find (g•f)(3) f(x)=3x-2 g(x)=x^2
Answers
Answer:
f(x)=3x-2
g(x)=x^2
(g o f)(3)=?
(g o f)(3)=g(f(3))
x=3→f(3)=3(3)-2
f(3)=9-2
f(3)=7
(g o f)(3)=g(f(3))=g(7)
x=7→g(7)=7^2
g(7)=49
Answer: (g o f)(3)=49
OR,if you like this answer can also work
For this case, the first thing we must do is the composition of functions.
We have:
f (x) = 3x-2
g (x) = x ^ 2
(gOf) (x) = (3x-2) ^ 2
We now evaluate the function:
(gOf) (3) = (3 * (3) -2) ^ 2
(gOf) (3) = (9-2) ^ 2
(gOf) (3) = (7) ^ 2
(gOf) (3) = 49
Answer:
(gOf) (3) = 49
Both are same

A six-sided die is rolled. What is the probability of rolling a three or six
Answers
Answer:
The probability is 1/6 for each side. Each side has a 1/6 chance of getting rolled.
It would be 2/6 if your trying to get either 3 or 6 because there's two sides you can get which would equal 2/6.
Step-by-step explanation:
I hope this helped, have a nice day!
The probability of rolling a three or six is 2/6
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes.
The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Given:
probability of getting 2= 1/6
probability of getting 6 = 1/6
So, the probability of rolling a three or six
=1/6 + 1/6
=2/6
=1/3
Hence, probability of rolling a three or six is 1/3.

M is the midpoint of LN. If LN = 90, what is LM?
Answers
Answer:
LM = 45
Step-by-step explanation:
M is the midpoint of LN. If LN = 90, what is LM?
L––––––N
From the question
M is the midpoint of LN.
Hence:
L––M––N
Since M is the Midpoint of LN, it means LN is divided in 2 equal parts
LM , MN
So, LM + MN = LN = 90
If LN = 90, LM = 90/2

6.3952 rounded to the nearest tenth
Answers
The decimal number 6.3952 rounded to the nearest tenth is 6.40.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, A decimal number 6.3952 and we have to round to the nearest tenth.
To round it to the nearest ten we'll look at the digit at the hundreds place which is 5 so we'll add one to the tens digit and make the digits after that zero.
Therefore, 6.3952 rounded to the nearest is 6.40.

Lauren bought 13.25 yards of yarn for $6.99. How much would it cost if she bought 24
yards of yarn?
Answers
We can use our knowledge to figure out the price of one yard by dividing both sides by 13.25:
13.25yards = 6.99
1yard = 699/1325
Then multiply both sides by 24 to get the price for 24 yards:
24yards = 12.6611321
As we are dealing with money we will only take the first two decimal points and NOT round:
24 yards would cost $12.66

Tip #1: Find the right string trimmer for you.
A few different string trimmers exist to meet the needs of you and your lawn:
Electric string trimmers tend to use lithium-ion batteries at 40 to 80 volts and are clean, quiet, and light. The uncorded versions add mobility to your work; however, corded electric string trimmers don’t require recharge time and are lighter.
Gas string trimmers use gas engines that provide more power than their electric counterparts. These trimmers are cordless and mobile, but you must regularly refuel for continued use. Some gas trimmers require a pull-start to crank, while other models come with an automatic crank.
String trimmer mowers, or walk-behind trimmers, resemble traditional lawnmowers without the size or the spinning blade. String trimmer mowers offer an in-between range for those lawn sections too big or too small for conventional mowers and trimmers.
Tip #2: Take safety precautions when using your string trimmer.
Like lawnmowers, string trimmers use a spinning motion to cut grass and thin wooden plants. For example, trimmers cutting in a counter clockwise spin will eject cut debris in a leftward direction.
Acknowledge the direction of your string trimmer’s spin and position yourself appropriately to avoid harmful debris hitting your body, like rock, glass, plastic, or any other small objects that can go flying when hit by the trimmer’s filament line. Additionally, keep children and pets indoors, or otherwise keep them and others on the opposite side of the eject direction.
Tip #3: Take advantage of spin direction when using your string trimmer.
Though you must heed the spin direction of your string trimmer for safety, the spin direction also commands the best use of your string trimmer. Ensure that your string trimmer ejects material away from your cut path to avoid working over piles of cut material, which drastically reduces the efficiency of your tool and encourages an uneven lawn trimming.
Tip #4: Use a cutting technique that fits the circumstance of your yard.
You accomplish a well-trimmed lawn by handling your string trimmer with precision. String trimmers seem clunky at best, but you can use a few different techniques to get that even cut you want. Mark Clement from Popular Mechanics suggests these methods:
Tapering: To cut along the boundaries of your lawn, angle the string trimmer so that the line cuts somewhat at an angle. You get your best cut toward the tip of the line, Clement explains, so tilting the trimmer slightly down helps cut smaller, more manageable portions while allowing the line to strike at its strongest point.
Edging: This method is useful when you need to cut grass at the edge of a parallel surface, such as a driveway or sidewalk. Instead of tilting the trimmer down, hold the tool so that the line cuts vertically. Clement notes that edging may uproot rocks and dirt and suggests easing these portions of your lawn into the right cut over time if you haven’t edged before.
Scything: Gently swing your string trimmer in a U-shaped pattern to navigate a difficult or obstructed area of the lawn. This method provides manageable trimming, and by overlapping the pattern, you’ll get the even cut you want.
Screeding: Clement explains that this method of using your string trimmer helps cut grass and weeds growing out of sidewalks, driveways, and other paved areas. Angle your string trimmer so that the line tip is hitting the pavement but the rest is slicing close to the base of the weed or grass.
Tip #5: Take care of your string trimmer.
Not unlike other tools, maintaining your string trimmer will keep it operable for years to come. After every use, wipe off grass and dirt debris from the line or replace it when necessary. String replacement is common, especially if you are using your string trimmer frequently. For gas-powered string trimmers, replace the spark plug every three to four months. Finally, empty the gas tank of the trimmer before long-term storage.
If you buy the right string trimmer for your needs, keep it properly maintained, and remember cutting direction for safety and a good cut, you’ll be using your string trimmer like a pro in no time.
