To determine a mixture that will make the same shade of green but a smaller amount, we can divide both the yellow and blue amounts by the same number.
How to find a mixture that will make the same shade of green but a smaller amount?To solve this problem, we can use the principle of proportionality, which states that if two ratios are equal, then the quantities they represent are proportional.
A. To find a mixture that will make the same shade of green but a smaller amount, we can divide both the yellow and blue amounts by the same number. For example, if we divide both amounts by 2, we get 1 cup of yellow and 1.75 cups of blue. This will create a smaller amount of the same shade of green.
B. To find a mixture that will make the same shade of green but a bigger amount, we can multiply both the yellow and blue amounts by the same number. For example, if we multiply both amounts by 2, we get 4 cups of yellow and 7 cups of blue. This will create a larger amount of the same shade of green.
C. To find a mixture that will make a different shade of green that is bluer, we can increase the amount of blue relative to the amount of yellow. For example, we could use 2 cups of yellow and 4 cups of blue, which would create a green that is bluer than the original shade.
D. To find a mixture that will make a different shade of green that is more yellow, we can increase the amount of yellow relative to the amount of blue. For example, we could use 3 cups of yellow and 2 cups of blue, which would create a green that is more yellow than the original shade.

What is division?In mathematics, the opposite of multiplication is the process called division. Finding the number of times one quantity is included within another is the procedure. The letters "/" or "" are typically used to denote this. For instance, 8 boys divided by 2 may be expressed as 8/2 or 82. The outcome in this situation would be 4, which is the quantity that 2 may be found in 8 times. The quotient, or outcome of the division, and the remainder, or quantity remaining after dividing, may both be found using division. Calculus, algebra, geometry, and other branches of mathematics all make use of the crucial mathematical notion of division.

Khadija has $0.90 worth of nickels and dimes. She has a total of 10 nickels and dimes altogether. By following the steps below, determine the number of nickels, x, and the number of dimes, y, that Khadija has.
Determine three ways to have a total of 10 coins:
Khadija has 8 nickels and 2 quarters
How to determine the number of each coin?From the question, we have the following parameters that can be used in our computation:
Worth of coins = $0.90
Type of coins = Dimes and quarters
Represent the nickels with n and the quarters with q
So, we have the following representation
n + q = 10
0.05n + 0.25q = 0.9
Make n the subject
n = 10 - q
So, we have
0.05(10 - q) + 0.25q = 0.9
Evaluate the products
0.5 - 0.05q + 0.25q = 0.9
This gives
0.2q = 0.4
Divide both sides by 0.2
q = 2
Recall that
n = 10 - q
So, we have
n = 10 - 2
Evaluate
n = 8
Hence, the number of nickels is 8

a rumor spreads among a group of 400 people. the number of people who have heard the rumor after t hours is given by:
Time required to spread the rumor so that half of the given heard the rumor is equal to 15 hours (approximately).
As given in the question,
Number of people among whom rumor is spread = 400
Number of people is represented by N(t)
Time is represented by 't' hours
Function representing relation between number of people who heard about the rumor and time
N(t) = 400/ ( 1+ 399 × e^(-0.4t) )
Condition : Half of the given number of people heard the rumor
N(t) = 400/2
= 200
Substitute the value in the function we get,
200 = 400/ ( 1+ 399 × e^(-0.4t) )
⇒ ( 1+ 399 × e^(-0.4t) ) = 400 ÷ 200
⇒ 1 + 399 × e^(-0.4t) = 2
⇒ 399 × e^(-0.4t) = 2 - 1
⇒ e^(-0.4t) = 1 ÷ 399
⇒ e^(-0.4t) = 0.002506
⇒ -0.4t = [tex]log _{e}[/tex] (0.002506)
⇒ t= 14.97 hours
⇒ t= 15 hours (round off)
Therefore, time required to spread the rumor among half of the given number of people is equal to 15hours(approximately).
The complete question is:
A rumor spreads among a group of 400 people. The number of people, N(t), who have heard the rumor by the time t in hours since the rumor started to spread can be approximated by a function of the form
N(t) = 400 / (1+399e^(-0.4t))

Aaliyah is going to invest in an account paying an interest rate of 5% compounded continuously. How much would Aaliyah need to invest, to the nearest hundred dollars, for the value of the account to reach $181,000 in 19 years?
Based on the given parameters, the value of the money to invest initially is $99341.383
How to determine the amount of investment?The given parameters about the compound interest are
Amount, A = $181000
Interest Rate, R = 5%
Time, t = 19 years
Number of times, n = 365 i.e. continuously
To calculate the amount, we have:
A = P + CI
Where
C = P(1 + R)^t
So, we have
A = P(1 + R)^t
This can be rewritten as
A = P(1 + R/n)^nt
Substitute the known values in the above equation
181000 = A * (1 + 5%/365)^(12*365)
So, we have
A = 181000 /[(1 + 5%/365)^(12*365)]

A = 99341.383
Hence, the amount of the investment is $99341.383

James earned a total of $68 last week. He earned $48 washing cars and won x dollars in an art contest. Which equation can be used to find the number of dollars James won in the art contest?
Answer:
Step-by-step explanation:
since $68 is your total, let's use the example z=y+x
z is our total, and we know that he made a total of $68, therefore z is the number 68.
We also know that James made a total of $48 washing cars, which gives us the answer 48 as y. So in order to find x, we would need to subtract 68 and 48, which is called using the communtative property. Thsi answer would give us the remaining amount of money we do not yet know.
So 68-48= 20. therefore James made $20 at the art contest.

How much do they need to sell to break even (where revenue is equal to cost)?
How much do they need to sell to make at least $5,000 in profit?
Do you think it is likely for them to make at least $5,000 in profit? In what situations
would it be possible for them to make at least $5,000 in profit?
The answer to this Question based on Profits is No they cant make 5000$ profit
What is profit?
Profit is simply the extra money we earn on selling good etc things and there are tonnes of different ways of making money and profit
Solution:
Here Diego high school soccer team started a fundraiser selling treats at their games
Initial money spent = 1000$
They decided to make 0.3$ revenue on both candy and soda hence total 0.6$ revenue in one pack
one pack costs for 2$ where 0.6$ is revenue and actual cost is 1.4$
Total packs to sell = 1000/1.4
= 714 packs

The manager's likely error is $20 if a store is instructed by corporate headquarters to put a markup of 11% on all items. An item costing $18 is displayed by the store.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
A markup of 11% on all items. An item costing $18 is displayed by the store manager at a selling price of $2.
The manager’s likely error was forgetting to add the $2 back to the $18.
$2= 11% of $18 = 1.98(=2)
For a markup,
= $2 + $18
