The ratio of water to milk in the waffles will be 5 : 3.
What is ratio?The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Given is that waffles are made with 2 1/2 cups water and 1 1/2 cups milk.
We can write the given mixed fractions as proper fractions -
2[tex]\frac{1}{2}[/tex] = 5/2 = W
1[tex]\frac{1}{2}[/tex] = 3/2 = M
Now, we can write the ratio of water to milk as -
[W]/[M] = (5/2)/(3/2) = 5/2 x 2/3 = 5/3
Therefore, the ratio of water to milk in the waffles will be 5 : 3.

There is a bag filled with 6 blue and 5 red marbles. A marble is taken at random from the bag, the colour is noted and then it is replaced. Another marble is taken at random. What is the probability of getting exactly 1 red?
The probability of getting exactly 1 red marble is 60/121.
Given data:
To find the probability of getting exactly 1 red marble, we need to consider the two possible scenarios:
Getting a red marble on the first draw and a blue marble on the second draw.
Getting a blue marble on the first draw and a red marble on the second draw.
The probability of getting a red marble on the first draw is 5/11, since there are 5 red marbles out of a total of 11 marbles in the bag.
The probability of getting a blue marble on the second draw is also 6/11, since we replace the marble after the first draw, so the number of marbles remains the same.
The probability of the first scenario occurring is (5/11) * (6/11) = 30/121.
Similarly, the probability of the second scenario occurring is (6/11) * (5/11) = 30/121.
To find the total probability of getting exactly 1 red marble, we add the probabilities of these two scenarios:
Total probability = (30/121) + (30/121)
= 60/121.
Hence, the probability of getting exactly 1 red marble is 60/121.

The probability of drawing exactly one red in two draws, considering the order, is the sum of the two scenarios: 'red then blue' and 'blue then red'. Here, the total probability is calculated as (5/11 * 6/11) + (6/11 * 5/11).
Explanation:The question presented falls under the concept of probability in Mathematics. We have a bag with 6 blue and 5 red marbles. A marble is chosen, its color is recorded, and then it is put back in the bag before another marble is chosen. Thus, the color of the first marble selected does not have any influence on the color of the second marble because of replacement.
To get the probability of drawing one red marble in two attempts, we can consider two possibilities: either the first draw is red and the second is blue, or the first draw is blue and the second is red.
Scenario 1: The first marble drawn is red and the second marble drawn is blue. The probability of drawing a red marble on the first attempt is 5/11, since there are 5 red marbles out of a total of (6+5)=11 marbles. After replacing the first marble, the probability of drawing a blue marble on the second try is 6/11. Therefore, the total probability for this possibility is the product of both individual probabilities: (5/11) * (6/11).
Scenario 2: The first marble drawn is blue and the second marble drawn is red. The probability is calculated in the same manner resulting into (6/11) * (5/11).
Finally, to get the total probability of drawing exactly one red marble in two draws, we add the probabilities for the two scenarios: (5/11 * 6/11) + (6/11 * 5/11).

April shoots an arrow upward at a speed of 80 feet per second from a platform 25 feet high. The pathway of the
arrow can be represented by the equation h = -16t2 + 80t + 25, where h is the height and t is the time in
seconds. What is the maximum height of the arrow?
90 feet
140 feet
125 feet
80 feet
Answer:
The maximum height of the arrow is 125 feet.
Step-by-step explanation:
The pathway of the arrow can be represented by the equation,
[tex]h = -16t^2 +80t + 25[/tex] .....(1)
Where h is height in in feet and t is time in seconds.
It is required to find the maximum height of the arrow. For maximum height, [tex]\dfrac{dh}{dt}=0[/tex].
So,
[tex]\dfrac{d(-16t^2 +80t + 25)}{dt}=0\\\\-32t+80=0\\\\t=\dfrac{80}{32}\\\\t=2.5\ s[/tex]
Put t = 2.5 s in equation (1). So,
[tex]h = -16(2.5)^2 +80(2.5) + 25\\\\h=125\ \text{feet}[/tex]
So, the maximum height of the arrow is 125 feet.
The students in Darnel's grade voted to select a guest speaker. 20 students voted for a famous athlete. If there are 100 students in Darnel's grade, what percentage of the students voted for the athlete?
Answer:
20% of the students voted for the athlete
Step-by-step explanation:
The proportion of students who voted for athlete is the number of students who voted for the athlete divided by the total number of students.
The percentage is the proportion multiplied by 100.
We have that:
20 students voted for the athlete.
Total of 100 students.
20/100 = 0.2
0.2*100 = 20%
20% of the students voted for the athlete
A poll is given, showing 45% are in favor of a new building project.
If 3 people are chosen at random, what is the probability that exactly 1 of them favor the new building project?
The probability of exactly 1 person favoring the new building project out of 3 people chosen at random is approximately 0.4083, or 40.83%.
Use the concept of probability defined as:
Probability is the ratio of the number of favorable outcomes to the total number of outcomes for the occurrence of an event.
Given that,
A poll was conducted on a new building project.
The results of the poll represent 45% of the respondents were in favor of the new building project.
To calculate the probability that exactly 1 person favoring the new building project out of 3 people chosen at random:
Use the binomial probability formula:
[tex]P(X=k) = (^nC_k) p^k (1-p)^{(n-k)}[/tex]
Where P(X=k) is the probability of getting exactly k favorable responses, and n is the total number of people chosen.
In this case, n = 2,
k is the number of favorable responses, in this case, 1,
p is the probability of an individual favoring the new building project in this case, 0.45,
And (1-p) is the probability of an individual not favoring the new building project in this case, 0.55.
Now substitute the values into the formula:
[tex]P(X=1) = (^3C_1) (0.45^1) (0.55^{(3-1)})[/tex]
Calculating the values:
[tex]^3C_1 = 3[/tex]
(which represents the number of ways to choose 1 favorable response out of 3 people),
[tex]0.55^{(3-1)} = 0.3025.[/tex]
Substituting these values back into the formula:
P(X=1) = (3)(0.45)(0.3025)
Calculating further:
P(X=1) = 0.4083
Hence,
The probability of exactly 1 person favoring the new building project out of 3 people chosen at random is approximately 0.4083, or 40.83%.

Final answer:
The probability of exactly 1 out of 3 individuals favoring a new building project is 40.35%.
Explanation:
The probability of a person favoring a new building project is 45%.
To find the probability that exactly 1 out of 3 chosen individuals favor the project, we use the binomial probability formula:
Calculate the probability of 1 person favoring the project: 0.45 * 0.55 * 0.55 = 0.1345
Calculate the number of ways 1 person can be chosen out of 3: 3 choose 1 = 3
Multiply the two results: 3 * 0.1345 = 0.4035
Therefore, the probability that exactly 1 out of 3 individuals favor the new building project is 0.4035 or 40.35%.

Deanna gets 3 problems incorrect on her math quiz and scores 85%. How many questions were on the quiz?
Answer:
There were 20 questions on the quiz
Step-by-step explanation:
In this question, we are concerned with knowing the number of questions on a quiz, given that Deana had a certain percentage after scoring an amount of marks.
We proceed as follows;
Let the number of questions on the quiz be X.
Now, she got 85% by making 3 incorrect choices. This means the percentage of questions she got incorrectly would be 100-85 = 15%
what we are saying is that it is just 15% of her questions that were wrong.
This mathematically;
15% of x = 3
15/100 * x = 3
15x = 3 * 100
15x = 300
x = 300/15
x = 20

384 = 6 x ( edge)^2
( edge)^2 = 64
( edge) = 8
Similalry;
Then the surface area of second box = 6( edge)^2
6,144 = 6 x ( edge)^2
( edge)^2 = 1024
( edge) = 32
