Answer:
A. 54.28 ft^2
Step-by-step explanation:
Area of the parallelogram = 48 ft^2
Area of the semicircles = 6.28 ft^2
A = π r^2
A = 3.14 (2)
A = 3.14 (4)
A = 12.56
12.56 ÷ 2 = 6.28 ft^2
48 + 6.28 = 54.28 ft^2
Answer:
54.28 ft^2
Step-by-step explanation:
In a math class there are 8 male students and 7 female students. A
student is randomly selected to go to the front office and leaves. A
second student is randomly selected to go to the office. What is the
approximate probability that both students that left were a male
students?
A.25%
B.26.7%
C.28.4%
D.50%
Answer: 26.7%
Step-by-step explanation:
The probability that the leftover students were both male is 26.7%. Hence the correct option is B.
The probability that both selected students are male can be calculated as follows:
Determine the probability of selecting a male student for the first pick: P(Male) = 8/(8+7) = 8/15
Since the first student selected was male, the probability of the second student being male as well is: P(Second Male|First Male) = 7/(8+6) = 7/14
Multiply the probabilities together to get the probability of both selected students being male: P(Both Male) = P(Male) * P(Second Male | First Male) = (8/15) * (7/14) = 4/15 or approximately 26.7%
The Jurassic Zoo charges $11 for each adult admission and $7 for each child. The total bill for the 264 people from a school trip was $2140. How many adults and how many children went to the zoo?
Answer:
59 Adults And 147 Children
Step-by-step explanation:
Since there were a total of 206 people, this means that x%2By=206
Also, because "The Jurassic Zoo charges $11 for adult admission and $9 for each child. the total bill for the 206 people from a school trip was $1972", this means that 11x%2B9y=1972
So we have the system:
system%28x%2By=206%2C11x%2B9y=1972%29
Let's solve it by substitution
Now in order to solve this system by using substitution, we need to solve (or isolate) one variable. I'm going to solve for y.
So let's isolate y in the first equation
x%2By=206 Start with the first equation
y=206-x Subtract x from both sides
y=-x%2B206 Rearrange the equation
---------------------
Since y=-x%2B206, we can now replace each y in the second equation with -x%2B206 to solve for x
11x%2B9highlight%28%28-x%2B206%29%29=1972 Plug in y=-x%2B206 into the second equation. In other words, replace each y with -x%2B206. Notice we've eliminated the y variables. So we now have a simple equation with one unknown.
11x%2B%289%29%28-1%29x%2B%289%29%28206%29=1972 Distribute 9 to -x%2B206
11x-9x%2B1854=1972 Multiply
2x%2B1854=1972 Combine like terms on the left side
2x=1972-1854Subtract 1854 from both sides
2x=118 Combine like terms on the right side
x=%28118%29%2F%282%29 Divide both sides by 2 to isolate x
x=59 Divide
-----------------First Answer------------------------------
So the first part of our answer is: x=59
Since we know that x=59 we can plug it into the equation y=-x%2B206 (remember we previously solved for y in the first equation).
y=-x%2B206 Start with the equation where y was previously isolated.
y=-%2859%29%2B206 Plug in x=59
y=-59%2B206 Multiply
y=147 Combine like terms
-----------------Second Answer------------------------------
So the second part of our answer is: y=147
-----------------Summary------------------------------
So our answers are:
x=59 and y=147
This means that 59 adults and 147 children went to the zoo.

What is a function ?
A function is a relationship between inputs and outputs where each input has precisely one output and the output can be linked to its input.
A graph is given which shows a function. We need to find out domain and the range of this function based on the graph.
We know that , in a graph , domain is always represented on the x - axis whereas we represent range on the y - axis. Also , the domain of a function is the input provided to the function whereas the output we get is the range of the function.
In the graph shown : the dots on the x-axis are connected by -5 and 1 . This meant x coordinate is (-5,1) and dots on the y-axis are connected by -4 and 7. This meant y - coordinate is (-4 , 7).
So ,
The domain will be -5 ≤ x ≤ 1 .
The range will be -4 ≤ x ≤ 7 .
Therefore , the domain of the given function is -5 ≤ x ≤ 1 and range of the given function is -4 ≤ x ≤ 7.

Step-by-step explanation:
The R.R. Bowker Company of New York collects data on annual subscription rates to periodicals. Results are published in Library Journal. In a recent independent study, it was found that 63% of all students at Mill University read Time magazine, 51% read U.S. News and World Report, and 24% read both magazines. If a student at Mill University is randomly selected, what is the probability that the student reads either the Time magazine or the U.S.News and World Report magazine?
Answer:
90%
Step-by-step explanation:
Let's call the percentage of students that read Time magazine by P(T), and the percentage of students that read U.S News and World Report by P(U). So, we have that:
P(T) = 0.63
P(U) = 0.51
P(T and U) = 0.24
To find the percentage of students that read either the Time magazine or the U.S.News and World Report magazine (that is, P(T or U)), we can use this formula:
P(T or U) = P(T) + P(U) - P(T and U)
So, we have that:
P(T or U) = 0.63 + 0.51 - 0.24 = 0.90
So the probability is 90%
The probability that a randomly selected student at Mill University reads either Time magazine or U.S. News and World Report magazine is 90%.
Explanation:The student is interested in finding the probability that a Mill University student reads either Time magazine or U.S. News and World Report magazine.
To calculate this, we use the formula for the probability of either event A or B occurring (P(A ∪ B) = P(A) + P(B) - P(A ∩ B)), where P(A ∪ B) represents the probability of A or B happening, P(A) is the probability of A happening, P(B) the probability of B happening, and P(A ∩ B) the probability of both A and B happening.
Given that 63% of students read Time (P(Time) = 0.63), 51% read U.S. News (P(U.S. News) = 0.51), and 24% read both (P(Both) = 0.24), we calculate the probability of a student reading either magazine as P(Either) = P(Time) + P(U.S. News) - P(Both) = 0.63 + 0.51 - 0.24 = 0.90, or 90%.

Write 4.768 as a common fraction, proper or improper and then reduce. .
The number n = 4.768 as a fraction is A = 596/125
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the number be represented as n
Now , let the fraction be A
where the value of n = 4.768
And , to convert a decimal to a fraction, we can write the decimal as a fraction with the decimal value in the numerator and a power of 10 in the denominator that corresponds to the number of decimal places.
For 4.768, the decimal value is 768, which is three decimal places to the right of the decimal point. Therefore, we can write:
4.768 = 4 + 0.768
= 4 + 768/1000
= 4000/1000 + 768/1000
= 4768/1000
This fraction can be reduced by dividing both the numerator and denominator by their greatest common factor, which is 8:
4768/1000 = (8 × 596)/(8 × 125)
A = 596/125
Hence , the fraction is A = 596/125
