The perimeter of a church window is 80 inches. If the window is in the shape of a square.what is the length of each side of the window?
Answers
The length of each side of the church window is 20 inches.
Explanation:To find the length of each side, we need to determine the perimeter of the square. The perimeter is the sum of all four sides of the square. In this case, it is given that the perimeter is 80 inches. Since all sides of a square are equal in length, we can divide the perimeter by 4 to find the length of each side. So, each side of the church window will be 80 inches divided by 4, which is 20 inches.

The number of cases of a new disease can be modeled by the quadratic regression equation y = –2x2 + 36x + 6, where x represents the year.
Which is the best prediction for the number of new cases in year 15?
A. 194
B. 96
C. 328
D. 614
Answers
Answer: B 96
Step-by-step explanation:
By evaluating the function in x = 15, we will see that in the year 15 there will be 96 cases.
Which is the best prediction for the number of new cases in year 15?
The function that predicts the number of cases in the year x is given by:
[tex]y = -2x^2 + 36x + 6[/tex]
So we just need to evaluate that function in x = 15, this means replacing x by 15.
[tex]y = -2*15^2 + 36*15 + 6 = 96[/tex]
So we can expect that in the year 15, there will be around 96 cases. Then the correct option is B.

Step-by-step explanation:
Given : Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles. Suppose a star is 13.6 light-years from Earth.
To find : In scientific notation, how many miles away is it?
Solution :
According to question,
The distance can travel in 1 light year is
[tex]1 \text{ light year} = 5,880,000,000,000 \text{ miles}[/tex]

A theatre contains 441 seats and the ticket prices for a recent play were $60 for adults and $16 for children. If the total proceeds were $14,800 for a sold-out matinee, how many of each type of ticket were sold?
Answers
x+y=441
that implies y=441-x so
14,800=60x+16(441-x)
14,800=60x+16*441-16x
14,800-16*441=44x

At a certain college, the probability that a student attends full-time is 0.320 and the probability that the student attends part-time is 0.680. At the same college, the probability that a student receives financial aid is 0.570 while the probability that a student does not receive financial aid is 0.430. If a student is randomly selected, what is the probability that the student attends full-time and does not receive financial aid?
Answers
the probability that a randomly selected student attends full-time and does not receive financial aid is ( 0.1376 ), or ( 13.76% ).
To find the probability that a student attends full-time and does not receive financial aid, we can use the multiplication rule for independent events.
Given:
- Probability of attending full-time: [tex]\( P(\text{full-time}) = 0.320 \)[/tex]
- Probability of not receiving financial aid:[tex]\( P(\text{no financial aid}) = 0.430 \)[/tex]
By the multiplication rule, the probability of both events occurring is the product of their individual probabilities:
[tex]\[ P(\text{full-time and no financial aid}) = P(\text{full-time}) \times P(\text{no financial aid}) \][/tex]
[tex]\[ = 0.320 \times 0.430 \][/tex]
[tex]\[ = 0.1376 \][/tex]
Therefore, the probability that a randomly selected student attends full-time and does not receive financial aid is ( 0.1376 ), or ( 13.76% ).

In a poll, respondents were asked whether they had ever been in a car accident. 215 respondents indicated that they had been in a car accident and 449 respondents said that they had not been in a car accident. If one of these respondents is randomly selected, what is the probability of getting someone who has been in a car accident? Round to the nearest thousandth, if necessary
Answers
The probability of getting someone who has been in a car accident will be 0.3238
Number of people that indicated that they had been in a car accident = 215 respondents
Number of people that said that they had not been in a car accident = 449
The probability of getting someone who has been in a car accident will then be calculated as:
= 215/664
= 0.3238
Therefore, the probability of getting someone who has been in a car accident will be 0.3238

Solve the system of equations using elimination. 2x + y = 9 8x – 2y = 6
Answers
(2) 8x – 2y = 6
You can eliminate the x or the y. I am going to eliminate the y
First multiply the first equation 2x + y = 9 by 2.
2x + y = 9
2(2x + y = 9)
4x +2y = 18
Now we have a new equation that we can use and we can eliminate the y from the other equation because +2y - 2y = 0. Lets do that now and solve for x.
4x +2y = 18
8x – 2y = 6
12x = 24
12x / 12 = 24 / 12
x = 2
So we found the value of x, which is 2. To find y, insert 2 into one of the original equations. I am going to use 2x + y = 9
2x + y = 9
2(2) + y = 9
4 + y = 9
-4 + 4 + y = 9 - 4
y = 9 - 4
y = 5
y = 5.
Our point is at (x, y) = (2,5)
x = 2
y = 5
a graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder displacing the level to 47.6 ml what is the volume of the granite piece in cubic centimeters?
Answers
The volume of the piece of granite is 6.1 cubic cm if the graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder, displacing the level to 47.6 ml.
What is volume?
It is defined as a three-dimensional space enclosed by an object or thing.
We have:
Volume of the water filled in the cylinder = 41.5 ml
Volume after placing the piece of granite = 47.6 ml
The volume of the piece of granite = 47.6 - 41.5 = 6.1 ml
As we know 1 ml = 1 cm³
The volume of the piece of granite = 6.1 cubic cm
Thus, the volume of the piece of granite is 6.1 cubic cm if the graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder displacing the level to 47.6 ml.

Step-by-step explanation:
Given the equation:
y = x – 1 ....[1]
y = 3x + 1 ....[2]
Equate equation [1] and [2] to solve for x.
[tex]x-1=3x+1[/tex]
Subtract x from both sides we have;

Subtract 1 from both sides we have;

Let’s establish first that our result is going to be negative. That’s a non-negotiable. Now, we can turn our attention to the 25/7. What is “one whole” when we’re dealing with sevenths? Well, splitting one whole thing into sevenths is the same as splitting it into 7 equal pieces, so in any one whole, we’ll have 7/7.
So, finding the *whole* part of 25/7 is the same thing as finding out how many *whole 7s* fit in 25. We can fit 3 whole 7s into 25, so our whole part is 3. Dividing 25 by 7 leaves us with *4/7* (since 7 x 3 = 21 and 25 - 21 = 4), so our fractional part is 4/7. Putting that together:
Adding back on the negative sign from the beginning, we find that our mixed number is [tex]-3 \frac{4}{7} [/tex].
