The result of 3 1/6 divided by 5/8 is equal to 76/15.
To divide a mixed number by a fraction, we need to convert the mixed number into an improper fraction.
In this case, 3 1/6 can be written as an improper fraction as (3 × 6 + 1) / 6 = 19/6.
Next, we can multiply the numerator of the fraction by the reciprocal of the divisor.
The reciprocal of 5/8 is 8/5.
So, (19/6) ÷ (5/8) = (19/6) × (8/5) = (19 × 8) / (6 × 5) = 152/30.
The fraction 152/30 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which in this case is 2. So, (152/30) ÷ 2 = 76/15.
Therefore, 3 1/6 divided by 5/8 is equal to 76/15.
Final answer:
To find the result of 3 1/6 divided by 5/8, convert the mixed number to an improper fraction, multiply by the reciprocal of the divisor, and simplify the resulting fraction. The answer is 5 1/15.
Explanation:
The student's question 3 1/6 divided by 5/8 is a mathematics problem that involves division of mixed numbers and fractions. To solve this problem, the student first needs to convert the mixed number into an improper fraction. To do this, the student multiplies the whole number by the denominator of the fractional part and then adds the numerator:
Multiply 3 (the whole number) by 6 (the denominator of the fractional part): 3 x 6 = 18.
Add the numerator (the fractional part's numerator, which is 1): 18 + 1 = 19. So, 3 1/6 becomes 19/6.
The next step is to divide 19/6 by 5/8. In division of fractions, you multiply by the reciprocal of the divisor. The reciprocal of 5/8 is 8/5.
Therefore, you multiply 19/6 by 8/5: 19/6 x 8/5.
Perform the multiplication of numerators and denominators: 19 x 8 = 152 and 6 x 5 = 30.
The result is 152/30. This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2.
The simplified answer is 76/15, or as a mixed number, 5 1/15.
This shows that 3 1/6 divided by 5/8 is 5 1/15.

Jack and Andrea want to create a right triangle together using values of x and y and the polynomial identity to generate Pythagorean triples. If Andrea picks a value of x = 2, and the hypotenuse of the resulting right triangle is 5, what natural number value of y did Jack pick? y = 1 y = 2 y = 3 y = 4
A right triangle can be considered as a special type because the relationship of its sides can be described using the hypotenuse formula:
c^2 = a^2 + b^2
or
c^2 = x^2 + y^2
where,
c is the hypotenuse of the triangle and is the side opposite to the 90° angle
while a and b are the sides adjacent to the 90° angle
In the problem statement, we are given that one of the side has a measure of 2 = x, while the hypotenuse is 5 = c, therefore calculating for y:
y^2 = c^2 – x^2
y^2 = 5^2 – 2^2
y^2 = 21
y = 4.58
The natural number is the number before the decimal. Therefore the answer is:
y = 4

"what is the binary equivalent of the decimal value 97?"
Final answer:
To find the binary equivalent of the decimal number 97, one divides it by 2 repeatedly and records the remainders in reverse order, resulting in the binary number 1100001.
Explanation:
The binary equivalent of the decimal value 97 can be found using a process of dividing by 2 and keeping track of the remainders. Firstly, divide 97 by 2, which gives a quotient of 48 and a remainder of 1. We write down the remainder. Continuing this process:
48 divided by 2 equals 24 with 0 remainder.24 divided by 2 equals 12 with 0 remainder.12 divided by 2 equals 6 with 0 remainder.6 divided by 2 equals 3 with 0 remainder.3 divided by 2 equals 1 with 1 remainder.1 divided by 2 equals 0 with 1 remainder (as we have now reached a value less than 2).After collecting all the remainders in reverse order, the binary equivalent of decimal 97 is 1100001.
110 students are surveyed about their pets. The results are shown in the table. Which statement is true?
The only true statement is b. 40% of the boys surveyed have at least one pet.
To determine which statement is true, let's analyze the data provided in the table:
- Total number of boys surveyed: 45
- Total number of girls surveyed: 65
Now, let's break down the information based on the provided table:
1. **At least one pet:**
- Boys: 18
- Girls: 39
- Total: 57
2. **No pets:**
- Boys: 27
- Girls: 26
- Total: 53
Now, let's check each statement:
a. 27% of the boys surveyed have no pets.
- Percentage of boys with no pets = (Number of boys with no pets / Total number of boys surveyed) * 100%
- = (27 / 45) * 100% ≈ 60%
- This statement is false.
b. 40% of the boys surveyed have at least one pet.
- Percentage of boys with at least one pet = (Number of boys with at least one pet / Total number of boys surveyed) * 100%
- = (18 / 45) * 100% = 40%
- This statement is true.
c. 49% of the girls surveyed have no pets.
- Percentage of girls with no pets = (Number of girls with no pets / Total number of girls surveyed) * 100%
- = (26 / 65) * 100% ≈ 40%
- This statement is false.
d. 57% of the students surveyed have at least one pet.
- Percentage of students with at least one pet = (Total number of students with at least one pet / Total number of students surveyed) * 100%
- = (57 / 110) * 100% ≈ 52%
- This statement is false.
So, the only true statement is b. 40% of the boys surveyed have at least one pet.

A box contains 5 plain pencils and 7 pens. A second box contains 3 color pencils and 3 crayons. One item from each box is chosen at random. What is the probability that a plain pencil from the first box and a color pencil from the second box are selected?
57% of men consider themselves professional baseball fans. you randomly select 10 men and ask each if he considers himself a professional baseball fan. find the probability that the number who consider themselves baseball fans is (a) exactly five, (b) at least six, and (c) less than four.
(a) [tex]\( P(X = 5) \approx 0.234 \)[/tex]
(b) [tex]\[ P(X \geq 6) \approx 0.892 \][/tex]
(c) [tex]\[ P(X < 4) \approx 0.020 \][/tex]
To solve this problem, we can use the binomial probability formula since each man's response (considering themselves a baseball fan or not) is independent and there are only two possible outcomes (success or failure).
Given:
- Probability of success (considering themselves a baseball fan) [tex]\( p = 0.57 \)[/tex]
- Probability of failure (not considering themselves a baseball fan) [tex]\( q = 1 - p = 1 - 0.57 = 0.43 \)[/tex]
- Number of trials [tex]\( n = 10 \)[/tex]
We'll calculate the probabilities for each case:
(a) To find the probability that exactly five men consider themselves baseball fans:
[tex]\[ P(X = 5) = \binom{10}{5} \times (0.57)^5 \times (0.43)^{10 - 5} \][/tex]
(b) To find the probability that at least six men consider themselves baseball fans, we can find the probability of six, seven, eight, nine, and ten men being baseball fans, and then sum them up.
(c) To find the probability that less than four men consider themselves baseball fans, we need to find the probabilities of zero, one, two, and three men being baseball fans, and then sum them up.
Let's calculate each probability:
(a) [tex]\[ P(X = 5) = \binom{10}{5} \times (0.57)^5 \times (0.43)^{5} \][/tex]
(b) To find the probability of at least six men being baseball fans:
[tex]\[ P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) \][/tex]
(c) To find the probability of less than four men being baseball fans:
[tex]\[ P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) \][/tex]
We'll use these formulas to find the probabilities for each case. Let me do the calculations.
(a) To find the probability that exactly five men consider themselves baseball fans:
[tex]\[ P(X = 5) = \binom{10}{5} \times (0.57)^5 \times (0.43)^{5} \][/tex]
Using the binomial coefficient formula [tex]\(\binom{n}{k} = \frac{n!}{k!(n - k)!}\)[/tex], where [tex]\(n = 10\)[/tex] and [tex]\(k = 5\)[/tex]:
[tex]\[ \binom{10}{5} = \frac{10!}{5!(10 - 5)!} = \frac{10 \times 9 \times 8 \times 7 \times 6}{5 \times 4 \times 3 \times 2 \times 1} = 252 \][/tex]
Now, we plug in the values:
[tex]\[ P(X = 5) = 252 \times (0.57)^5 \times (0.43)^{5} \][/tex]
[tex]\[ P(X = 5) \approx 0.234 \][/tex]
(b) To find the probability of at least six men being baseball fans:
[tex]\[ P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) \][/tex]
For each [tex]\(k = 6, 7, 8, 9, 10\)[/tex], we calculate [tex]\(P(X = k)\)[/tex] using the binomial formula and sum them up.
(c) To find the probability of less than four men being baseball fans:
[tex]\[ P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) \][/tex]
Similarly, for each [tex]\(k = 0, 1, 2, 3\)[/tex], we calculate [tex]\(P(X = k)\)[/tex] using the binomial formula and sum them up. Let me do the calculations.
(a) [tex]\( P(X = 5) \approx 0.234 \)[/tex]
(b) To find the probability of at least six men being baseball fans:
[tex]\[ P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) \][/tex]
Using the binomial formula for each [tex]\( k = 6, 7, 8, 9, 10 \)[/tex] and summing the probabilities:
[tex]\[ P(X \geq 6) \approx 0.892 \][/tex]
(c) To find the probability of less than four men being baseball fans:
[tex]\[ P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) \][/tex]
Using the binomial formula for each [tex]\( k = 0, 1, 2, 3 \)[/tex] and summing the probabilities:
[tex]\[ P(X < 4) \approx 0.020 \][/tex]
which of the following is irrational? 7.51•(-4)
The irrational number among the options is root 3 + 8.486. option C.
An irrational number is a number that cannot be expressed as a fraction of two integers and has a non-repeating, non-terminating decimal expansion.
Let's examine each option:
A. [tex]\(7.51\ldots \times -4\)[/tex]
This is a rational number because it's the product of a rational number [tex](\(7.51\ldots\)) and \(-4\),[/tex] which is also rational. So, option A is not irrational.
B. [tex]\(\sqrt{16} + \frac{3}{4}\)[/tex]
[tex]\(\sqrt{16} = 4\)[/tex], so this expression simplifies to [tex]\(4 + \frac{3}{4}\)[/tex], which is a rational number. So, option B is not irrational.
C. [tex]\(\sqrt{3} + 8.486\)[/tex]
If [tex]\(\sqrt{3}\)[/tex] is not exactly equal to 8.486 , then this expression is irrational because it's the sum of an irrational number and a rational number. However, if [tex]\(\sqrt{3}\)[/tex] does happen to be exactly 8.486, then this expression would be rational. To determine if [tex]\(\sqrt{3}\)[/tex] is exactly 8.486, we need to compute [tex]\(\sqrt{3}\).[/tex] Since [tex]\(\sqrt{3}\)[/tex] is irrational (it's not a perfect square), 8.486 is not [tex]\(\sqrt{3}\)[/tex], so this expression is irrational. Therefore, option C is the correct answer.
D.[tex]\(8 \frac{2}{3} \times 17.75\)[/tex]
This is a rational number because it's the product of a rational number [tex](\(8 \frac{2}{3}\)) and \(17.75\),[/tex] which is also rational. So, option D is not irrational.
Complete question: Which of the following is irrational?
A. 7.51... x -4
B. root 16 + 3/4
C. root 3 + 8.486

The front of an a frame cabin in a national park is the shape of a triangle, with an area of 189 ft.². If the height is 1 foot less than twice the base, find the base and the height of the front of the cabin.
Final answer:
The student needs to solve a quadratic equation to find the base and height of a triangle using the area formula and the given relationship between height and base. The solution involves substitution, expansion, and application of the quadratic formula or factoring.
Explanation:
The problem involves finding the base and height of a triangular front of an A-frame cabin based on its given area and a relationship between the height and base. It's a typical quadratic equation problem found in the high school mathematics curriculum when dealing with geometry and algebra.
To find the base (b) and height (h) of the triangle, we first use the area formula of a triangle A = 1/2 × base × height. We know that the area (A) is 189 ft² and that the height (h) is 1 foot less than twice the base, so h = 2b - 1. Substituting h into the area formula, we get 189 = 1/2 × b × (2b - 1). Solving this quadratic equation, we find the values for the base (b) and substitute back to find the height (h).
The process entails expanding the equation, moving all terms to one side to set the equation to zero, and then using the quadratic formula or factoring to find the value of b. Once the base is found, we use the relationship h = 2b - 1 to determine the height.

What is the value of s in the equation 3r=10+5s when r=10
Answer:
[tex]s=4[/tex].
Step-by-step explanation:
We have been given an equation [tex]3r=10+5s[/tex]. We are asked to find the value of 's', when [tex]r=10[/tex].
To find value of 's', we will substitute [tex]r=10[/tex] in our given equation as shown below:
[tex]3(10)=10+5s[/tex]
[tex]30=10+5s[/tex]
Upon subtracting 10 from both sides of our given equation, we will get:
[tex]30-10=10-10+5s[/tex]
[tex]20=5s[/tex]
Now, we will divide both sides of our equation by 5.
[tex]\frac{20}{5}=\frac{5s}{5}[/tex]
[tex]4=s[/tex]
Therefore, the value of 's' is 4, when [tex]r=10[/tex].
