The volume of the cylinder is 1177.5 cubic inches.
Given that the diameter of the cylinder is 10 inches, the radius r is half of that, so [tex]\( r = \frac{10}{2} = 5 \)[/tex] inches.
The height h is three times the radius, so [tex]\( h = 3r = 3 \times 5 = 15 \)[/tex] inches.
Now, we can substitute these values into the formula for the volume of a cylinder:
[tex]\( V = \pi r^2 h \)\\ \( V = 3.14 \times (5)^2 \times 15 \)\\ \( V = 3.14 \times 25 \times 15 \)\\ \( V = 3.14 \times 375 \)\\ \( V = 1177.5 \) cubic inches.[/tex]

How many 2/3- cup servings are in 6 cups of yogurt
Answer: The required number of servings in 6 cups of yogurt is 9.
Step-by-step explanation: We are given to find the number of [tex]\dfrac{2}{3}[/tex] cup servings in 6 cups of yogurt.
We will be using the UNITARY method to solve the given problem.
We have
Number of servings in [tex]\dfrac{2}{3}[/tex] cups of yogurt = 1.
So, the number of servings in 1 cup of yogurt will be
[tex]\dfrac{1}{\frac{2}{3}}=\dfrac{3}{2}.[/tex]
Therefore, the number of servings in 6 cups of yogurt is given by
[tex]\dfrac{3}{2}\times6=9.[/tex]

If m C=66, find the values of x and y.
A) x = 24, y = 66
B) x = 90, y = 66
C) x = 90, y = 24
D) x = 66, y = 24
Answer:
C) x=90°, y=24°
Step-by-step explanation:
The two sections into which A is split, are the same size as indicated. Sides AB and AC are the same length. Because of those reasons, it can be concluded that B and C are the same size.
The corners of a triangle adds up to 180°. For ΔABC:
[tex]A+B+C=180\\A+2(66)=180\\A=48[/tex]
y° is half of A:
∴y° = 24°
Now add up the corners of triangle ABD:
[tex]y+x+B=180\\24+x+66=180\\x=90[/tex]
∴x° = 90°
mr. lee had a bag of red beans and a bag of black beans. 20% of the total number of beans were black, and there were 180 ounces more red beans than black beans. he transferred some red beans to the bag containing black beans, so that, the bag now contained 30% of the total number of beans. How many ounces of beans were there in the bag of mixed beans
Final answer:
After finding the total weight of beans based on the given percentages and difference in weight between red and black beans, we determine that there are 90 ounces of beans in the mixed bag.
Explanation:
The question asks us to find out how many ounces of beans are now in the bag of mixed beans, given certain percentages before and after mixing. We know that initially, 20% of the total beans are black, and the rest are red. After Mr. Lee transferred some red beans to the bag containing black beans, the bag contained 30% of the total number of beans.
To solve this, let's denote the total number of beans by T, the number of black beans by B, and the number of red beans by R. According to the information provided:
20% of T is black beans: B = 0.20TThere are R = B + 180 oz of red beans.After transferring, the mixed bag contains 30% of T.First, we use the initial conditions to write an equation for the total number of beans T. Since R is 180 ounces more than B:
T = B + R
T = B + (B + 180)
T = 2B + 180
Given that B is 20% of T, we can also write this as:
T = 2(0.20T) + 180
T = 0.40T + 180
We can now solve for T:
T - 0.40T = 180
0.60T = 180
T = 180 / 0.60
T = 300 ounces
Since we know that the mixed bag contains 30% of the total, we calculate 30% of 300 ounces:
30% of T = 0.30 x 300
30% of T = 90 ounces
Therefore, after transferring, there are 90 ounces of beans in the mixed bag.

Final answer:
The line with an undefined slope is D. x = 2, which is a vertical line with a constant x-value for all points on the line.
Explanation:
The question asks which line has an undefined slope. An undefined slope occurs when a line is vertical since slope is defined as the change in y over the change in x, and in a vertical line the change in x is zero. Looking at the options given, the equation representing a vertical line is D. x = 2. This line is vertical because it has the same x-value for all points on the line, meaning there is no change in x as you move along the line, thus creating an undefined slope.

How to work with negative exponents
Final answer:
Negative exponents indicate the reciprocal of the base raised to the corresponding positive exponent. When multiplying or dividing with negative exponents, add or subtract them accordingly. In scientific notation, divide the coefficients and subtract the exponents to divide numbers.
Explanation:
Working with negative exponents is an essential skill in mathematics, where a negative exponent indicates the inverse or reciprocal of the base raised to the corresponding positive exponent. For example, 2-1 equals 1/2, which means that we are finding the reciprocal of 2. In operations involving exponents, such as multiplication and division, we follow certain rules with negative exponents:
When multiplying numbers, add the exponents (negative exponents included).
When dividing numbers, subtract the exponents (again, include negative exponents).
To convert a negative exponent into a positive one, take the reciprocal of the base with the corresponding positive exponent.
Here's an example of division in scientific notation: 106 ÷ 103 = 10(6-3) = 103. If you need to divide two numbers using scientific notation, you divide the coefficients and subtract the exponents.
Remember, a number like 3-4 is equivalent to 1/34, or 1 divided by 3 multiplied by itself four times. In general, negative exponents flip the base to the denominator, signifying a division rather than multiplication.

Jacob wants to use an elevator to carry identical packages having the same weight. Each package weighs 3 pounds and Jacob weighs 99 pounds. If the elevator can carry a maximum of 300 pounds at a time, which inequality shows the maximum number of packages, n, that Jacob can carry with himself in the elevator if he is the only passenger?
Answer:
The required inequality that shows the maximum number of packages is [tex]n\leq 67[/tex].
Step-by-step explanation:
Consider the provided information.
Each package weighs 3 pounds and Jacob weighs 99 pounds.
let n is the maximum number of package that Jacob can carry with himself in the elevator.
Thus, the total weight of Jacob while having n packages on the elevator is:
[tex]3n+99[/tex]
The elevator can carry a maximum of 300 pounds at a time, therefore.
[tex]3n+99\leq 300[/tex]
Now, subtract 99 from both sides and divide the obtained inequality with 3.
[tex]3n+99-99\leq 300-99[/tex]
[tex]3n\leq 201[/tex]
[tex]\frac{3n}{3}\leq \frac{201}{3}[/tex]
[tex]n\leq 67[/tex]
Thus, the Jacob can carry maximum 67 packages.
Hence, the required inequality that shows the maximum number of packages is [tex]n\leq 67[/tex].

Suppose Lisa places $8500 in an account that pays 16% interest compounded each year. Assume that no withdrawals are made from the account.
Follow the instructions below. Do not do any rounding.
(a) Find the amount in the account at the end of 1 year.
(b) Find the amount in the account at the end of 2 years.
At the end of 1 year, the amount in the account will be $9860. At the end of 2 years, the amount in the account will be $11437.6. This is calculated using the formula for compound interest.
Explanation:Lisa is placing $8500 in an account that pays 16% interest compounded annually. To solve for part (a) and part (b) which ask for the amount in the account at the end of 1 year and 2 years respectively, we use the formula for compound interest: A = P *(1 + r/n)^(nt).
Here, P is the principal amount ($8500), r is the annual interest rate (16% or 0.16 as decimal), n is the number of times that interest is compounded per unit t (n = 1 as it's compounded annually), and t is the time the money is invested for.
For (a), t = 1 year. Inserting these values into the formula, we get:
A = $8500 * (1 + 0.16/1)^(1*1) = $8500 * 1.16 = $9860.
Therefore, at the end of 1 year, the amount in the account will be $9860.
For (b), t = 2 years. Using the same formula, we get:
A = $8500 * (1 + 0.16/1)^(1*2) = $8500 * 1.16^2 = $11437.6.
Therefore, at the end of 2 years, the amount in the account will be $11437.6.

90% of students at a university use a backpack, while the rest do not. Of all the students, 50% carry their laptops with them and 5% carry neither a backpack nor laptop. What percentage of students carry their laptops and use a backpack?
The percentage of students who carry their laptops and use a backpack is 45%.
Explanation:To find the percentage of students who carry their laptops and use a backpack, we need to subtract the percentage of students who carry neither a backpack nor laptop from the percentage of students who carry their laptops.
Given that 5% carry neither a backpack nor laptop, we can subtract this from the 50% who carry their laptops to find that 45% of students carry their laptops and use a backpack.
