Debbie’s pizza shack cuts a large pizza into 10 equal slices. The diameter of the pizza is 16 inches. Bob eats two slices of pizza. How much pizza does he eat ?
Solution:
There are 10 equal slices of pizza
Out of 10 slices bob eats 2 slices.
So, out of one pizza bob eats [tex] \frac{2}{10} [/tex] or [tex] \frac{1}{5} [/tex] th of the pizza
Calculating in terms of area,
Diameter of Pizza= 16 inches
So, Radius of Pizza= [tex] \frac{Diameter}{2} [/tex]
Radius of pizza=[tex] \frac{16}{2} [/tex]=8inches
Area of complete pizza= πr²=π8²=64π=200.96inches²
Area of the part had by Bob=[tex] \frac{1}{5} [/tex]*200.96 inches²
=40.192inches²
Bob had 40.192 inches² out of 200.96 inches² pizza

Marcus painted 1/3 of his bedroom in 4/5 of an hour. at this rate how long will it take him to paint his entire room
Answer:
So it took him 4/5 of an hour to paint 1/3
that means there is still 2/3 to go
so that means that he will have two times that time to paint the rest of the room
4/5 = ?
1/3 2/3
using cross multiplication
(4/5)(2/3) = (1/3) (?)
8/15 = 1/3 ?
divide both sides by 1/3
so that will be 8/5
that means it will take 8/5 of an hour to complete the rest
or 12/5 total to do entire room

We have,
To write the fraction 22/3 as a mixed fraction, we need to divide the numerator (22) by the denominator (3) and express the result as a whole number plus a proper fraction.
When we divide 22 by 3, we get a quotient of 7 and a remainder of 1.
The quotient represents the whole number part, and the remainder becomes the numerator of the proper fraction.
Thus,
22/3 can be written as the mixed fraction 7 1/3.
This means that we have 7 whole units and an additional 1/3 unit.

A survey was conducted on 800 students regarding the number of automobiles in their household. A sample mean of 2.7 automobiles was determined, with a standard deviation of 0.7 automobiles. Assuming a 95% confidence level, which of the following statements holds true?
The statement that holds true with a 95% confidence level is true population mean of the number of automobiles in households of students is between 2.6524 and 2.7476."
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
To determine which of the following statements holds true, we need to use the confidence interval formula:
Confidence Interval = sample mean ± (critical value x standard error)
where the critical value is determined by the confidence level and the standard error is calculated using the formula:
standard error = standard deviation / sqrt(sample size)
With a 95% confidence level, the critical value is 1.96. Plugging in the values given in the question, we get:
standard error = 0.7 / sqrt(800) = 0.0247
Confidence Interval = 2.7 ± (1.96 x 0.0247) = (2.6524, 2.7476)
Therefore, the statement that holds true with a 95% confidence level is:
"The true population mean of the number of automobiles in households of students is between 2.6524 and 2.7476."

What rate of simple interest is needed for $700 to double, in 3 years?
The rate of simple interest required for $700 to double in 3 years is found using the formula I=PRT. In this scenario, the rate comes out to be approximately 33.3%.
Explanation:The subject of this question is finding the rate required for simple interest to cause an investment of $700 to double in a duration of 3 years.
Generally, we use the formula for simple interest: I=PRT where P is the principal amount (700 in this case), I is the interest earned, R is the rate we want to find and T is the time period in years.
However, since the aim is for the $700 to double, the interest earned will be an additional $700, thereby making the total $1400. Thus, substituting these values into the formula, we get 700 = 700 * R * 3. Simplifying this, we find that R = 700/(700*3) = 1/3 or approximately 33.3%.
Hence, the rate of simple interest required for $700 to double in 3 years is approximately 33.3%.

R = 1/3 or 33.33%. So, the simple interest rate needed for $700 to double in 3 years is approximately 33.33%.
To find out the simple interest rate that is needed for $700 to double in 3 years, we can set up the equation based on the formula for simple interest, which is I = PRT (where I is the interest, P is the principal amount, R is the rate of interest, and T is the time period in years).
Since the student wants the money to double, the interest gained should be equal to the principal, which means I = $700. The time given is T = 3 years. Plugging these values into our formula, we get:
$700 = $700 × R × 3
By dividing both sides by $2100 ($700 ×3), the equation simplifies to:
R = $700 / $2100
Therefore, R = 1/3 or 33.33%. So, the simple interest rate needed for $700 to double in 3 years is approximately 33.33%.

John ,Rick , and Molli are painting a room together. It takes all of them 16 hours to paint the room to perfection. It takes John 8 hours to paint the room alone , and it takes Rick 2 hours to paint the room alone. What is the hourly rate it take’s of john to paint the room alone?
John's hourly rate of painting a room alone is 1/8 of the room per hour, which is calculated from the time he takes to complete the job on his own.
The question asks for the hourly rate at which John can paint a room alone. Knowing that John takes 8 hours to paint the room by himself, we can find his hourly rate by understanding the concept of work rates in combination tasks. Since painting can be considered a task that involves continuous work, the rate at which the room gets painted relates directly to a painter’s work rate, which is the fraction of the room they can paint per hour. For John, his work rate is the reciprocal of the time he takes to paint the room alone, which in this case is 1/8 of the room per hour.

Given:In quadrilateral WXYZ , WY and XZ bisect each other at point A. Prove: Quadrilateral WXYZ is a parallelogram.
Given that the diagonals WY and XZ in a quadrilateral WXYZ bisect each other, we can confidently say that quadrilateral WXYZ is a parallelogram. This is based on the property of a parallelogram which states that its diagonals bisect each other.
Explanation:To prove that a quadrilateral is a parallelogram given that the diagonals bisect each other, we'll apply the properties of a parallelogram. According to the properties of a parallelogram, the diagonals bisect each other. That is to say, if WY and XZ bisect each other at point A (i.e., WA=AY and AZ=ZX), then WXYZ is a parallelogram. This satisfies the condition for the given quadrilateral and hence WXYZ is a parallelogram.
We use this information along with the parallelogram rule and the Pythagorean theorem to prove the quadrilateral is, in fact, a parallelogram. The rule states that if a quadrilateral has diagonals that bisect each other then it is a parallelogram.
In this case, since WY and XZ bisect each other at point A, we know that the lengths WA = AY and XA = AZ. Hence, quadrilateral WXYZ is indeed a parallelogram.
