The percent of those interviewed said they like orange juice for breakfast is 58%.
What is a percentage?A percentage is a number or ratio that can be expressed as a fraction of 100 in mathematics. If we need to calculate the percentage of a number, divide it by the whole and multiply by 100. As a result, the percentage denotes a part per hundred. The term % refers to one hundred percent.

Ayish used the quadratic formula to solve a quadratic equation in y to get y=7+-sqrt of 160/10
The solutions for y are:
y = (7 + 4sqrt(10))/10y = (7 - 4sqrt(10))/10To solve this problemWe can simplify the expression sqrt(160) by factoring 160 into its prime factors:
160 = 2^5 * 5
Taking the square root of each factor, we get:
sqrt(160) = sqrt(2^5 * 5) = sqrt(2^4 * 2 * 5) = 2^2 * sqrt(2 * 5) = 4 * sqrt(10)
Therefore, we can simplify the expression for y as follows:
y = (7 +- sqrt(160))/10 = (7 +- 4sqrt(10))/10
So the solutions for y are:
y = (7 + 4sqrt(10))/10
y = (7 - 4sqrt(10))/10

Express cos � L as a fraction in simplest terms.
Answer:
cos(L) = (√46)/11
Step-by-step explanation:
You want cos(L) in simplest terms, given right triangle side lengths LK=√46 and JK=√75.
CosineThe cosine is the ratio ...
Cos = Adjacent/Hypotenuse
The side adjacent to vertex L is LK. The hypotenuse of the triangle is LJ. This means the desired ratio is ...
cos(L) = LK/LJ
Pythagorean theoremThe length of hypotenuse LJ can be found using the Pythagorean theorem.
LJ² = LK² +JK²
LJ² = (√46)² +(√75)² = 46 +75 = 121
LJ = √121 = 11
RatioThen the desired ratio is ...
cos(L) = (√46)/11

A path 2.5 M is running around a square field whose side is 45 M find area path
The area of the path running around the square field is 475 square meters.
To find the area of the path running around a square field with a side of 45 meters and a path width of 2.5 meters,
Calculate the area of the entire square (including the path):
Side of the larger square = 45 M (side of the field) + 2.5 M (width of the path on one side) + 2.5 M (width of the path on the opposite side) = 50 M
Area of the larger square = (Side of the larger square)²
= (50 M)²
= 2500 M²
Calculate the area of the square field (without the path):
Side of the field = 45 M
Area of the square field = (Side of the field)²
= (45 M)²
= 2025 M²
Subtract the area of the square field from the area of the entire square to find the area of the path:
Area of the path = Area of the larger square - Area of the square field
= 2500 M² - 2025 M²
= 475 M²
So, the area of the path running around the square field is 475 square meters.

The collection of two or more linear equations is called as system of linear equations. The linear equations have the degree of variable as one. Though a single linear equation can have infinite number of solutions, but a pair of linear equation can be classified as consistent or inconsistent. The equations which are consistent have either one solution or infinte solutions. The intersecting pair of consistent equations have unique solution whereas the coinciding pair of consistent equations have infinite number of solutions. The equations which are inconsistent are the parallel lines which do not have any solution.

In a math class with 28 students, a test was given the same day that an assignment was due. There were 18 students who passed the test and 19 students who completed the assignment. There were 7 students who failed the test and also did not complete the assignment. What is the probability that a student who did not complete the homework passed the test?
Therefore, the probability that a student who did not complete the homework passed the test is 2/5 or 0.4 (or 40%).
What is Probability?Probability is a measure of the likelihood of an event occurring. It is a numerical value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
To calculate the probability of an event, we divide the number of favorable outcomes by the total number of possible outcomes. For example, if we toss a fair coin, the probability of getting heads is 1/2 because there is one favorable outcome (getting heads) out of two possible outcomes (getting heads or tails).
Let's define the following events:
A: passing the test
B: completing the assignment
We know that:
[tex]P(A) = 18/28 = 9/14[/tex] (since 18 students out of 28 passed the test)
[tex]P(B) = 19/28[/tex] (since 19 students out of 28 completed the assignment)
P (A ∩ B) = P(B) = 19/28 (since every student who completed the assignment also took the test)
We want to find P (A | not B), which represents the probability of passing the test given that the student did not complete the assignment.
Using Bayes' theorem, we have:
P (A | not B) = P (not B | A) * P (A) / P (not B)
We know that:
P (not B | A) = P (A' ∩ B') / P(A') = 7/28 / 10/28 = 7/10 (since 7 students failed the test and did not complete the assignment)
P (not B) = 1 - P(B) = 9/28 (since not completing the assignment is the complement of completing the assignment)
Plugging in these values, we get:
[tex]P(A | not B) = (7/10) * (9/14) / (9/28)[/tex]
[tex]P(A | not B) = 2/5[/tex]

What is equation of circle?The equation of a circle is a formula that describes the relationship between the x and y coordinates of any point on the circle.
The standard equation of circle is:
(x - h)²+(y - k)²=r²
This equation states that the sum of the squares of the differences between the x-coordinate and the center, and the y-coordinate and the center, is equal to the square of the radius.

How long must the brace be on a closet rod holder if the vertical side is 15 cm and the horizontal side must be attached 35 cm from the wall?
The brace must be approximately 38.1 cm long.
To find the length of the brace for the closet rod holder,
we can use the Pythagorean theorem,
which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the vertical side is 15 cm and the horizontal side is 35 cm.
Let's call the length of the brace (the hypotenuse) "c".
According to the Pythagorean theorem:
[tex]c^2 = (15 cm)^2 + (35 cm)^2[/tex]
[tex]c^2 = 225 cm^2 + 1225 cm^2[/tex]
[tex]c^2 = 1450 cm^2[/tex]
Now, to find the length of the brace, we need to take the square root of both sides:

What is Algebraic expression ?
An algebraic expression is a mathematical phrase that can contain variables, constants, and operators (such as addition, subtraction, multiplication, and division) that are used to represent quantities and their relationships.
To solve the system using addition, we want to add the two equations together in a way that eliminates one of the variables. In this case, we can add the two equations directly because the x term will cancel out:
X - 4.7y = -9.1
+(-x + 5.8 = 12.4)
1.1y = 3.3
Now we can solve for y by dividing both sides by 1.1:
y = 3.3 ÷ 1.1
y = 3
Substituting y = 3 back into one of the original equations, we can solve for x:
x - 4.7y = -9.1
x - 4.7(3) = -9.1
x - 14.1 = -9.1
x = 5
Therefore, the solution to the system of equations is x = 5 and y = 3.

Step-by-step explanation:
A General Linear function is as the following:
y = mx + c, Where: m: slope of the line, c: y-intercept
Given that:
Point 1 (P1) = (1,5)
Point 2 (P2) = (3, 11)
Point 3 (P3) = (7,y)
By substituting in the linear function with P1:
5 = m + c ---> (1)
By substituting in the linear function with P2:
11 = 3m + c ---> (2)
By multiplying equation (1) times 3 and subtracting eq. (2) from it:
(15 = 3m + 3c) - (11 = 3m + c) =
4 = 2c
Then, c = 2
By substituting with "c" in eq. (1):
5 = m + 2
Then, m = 3
Hence,
the function of this line is:
y = 3x + 2
So,
to get "y" in P3, we are going to substitute with 7:
y = 3(7) + 2
then "y" in P3 = 23
Another Solution:
by getting the slope of the line:
[tex]Slope = \frac{\triangle y}{\triangle x}[/tex] Where: Δy: change in y points, Δx: change in x points
by utilizing P1 & P2 in slope formula:
[tex]slope = \frac{11 - 5}{3 - 1} = \frac{6}{2} = 3[/tex]
By substituting with P1 in the linear function:
5 = 3 + c
Then, c = 2
the function of the line is:
y = 3x + 2
So,
to get "y" in P3, we are going to substitute with 7:
y = 3(7) + 2
then "y" in P3 = 23
hope you find this easy to understand....

Complete the following statement. Write your answer as a decimal or whole number.
__% of $5,000 = $3,750
Jhonny has 87 apples, and 90 pears. he needs to make a smoothy for his friends. The resipide needs 45.8 ounces of pear juice and 50 ounces of apple juice. Does Jhonny have enough to make the smoothys for his friends if he has 5 friends? Why or why not.
No, Johnny does not have enough fruit to make smoothies for his 5 friends because he is short 383.51 ounces of juice.
