Answer:
When you find the volume of the cylinder you square instead which isn't equal to multiplying so the answer will be more then doubled.
Step-by-step explanation:
Answer:
The volume of the first is not 2 * volume of the second. They both have the same volume.
Step-by-step explanation:
The 2 cylinders described are identical. The diameter = 2 times the radius, so the radius of the first cylinder = 1/2 * 7 = 3.5 in, which is the same as the radius of the second one. Also the heights are the same so the volumes are the same too.

A and B are two events. P(A) = 0.54; P(B) =0.42; p(A or B) = 0.85. Find the probability of A and B.
Answer:
0.98
Step-by-step explanation:
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.13 + 0.85 - 0
P(A or B) = 0.98
Note that P(A and B) is 0. This is because we are told A and B are mutually exclusive events. This means both events cannot happen simultaneously. An example would be flipping a coin to have it land on heads and tails at the same time.

Because Anastasia is bored at home during the quarantine, she decides to redecorate. The dimensions of her living room are approximately 18 ft x 12 ft with a nine-foot ceiling. Instead of painting the walls like an average person would, she wants to cover them with burgundy wallpaper.
Part A: If one roll of wallpaper covers 50
2
, then determine how many rolls of wallpaper is needed to cover the living room.
Part B: If one roll of paper cost $15.90, then determine the cost of the wallpaper (before taxes).
Answer:
6 rolls of paper is needed to cover the living room
The cost of the 6 rolls is $95.40
Step-by-step explanation:
There are four walls here, two 12 ft by 9ft walls, and two 18 ft by 9ft walls
Area of a rectangle = length * height
Area of walls 1&3 = 18 * 9 = 162 [tex]ft^{2}[/tex]
Area of walls 2&4 = 12 * 9 = 108 [tex]ft^{2}[/tex]
Total area of walls = 162 + 108 = 270 [tex]ft^{2}[/tex]
One roll for every 50 [tex]ft^{2}[/tex]
270 ÷ 50 = 5.4 rolls
Since you cant buy 0.4 rolls of wallpaper, you need to buy one whole roll instead
6 rolls of paper is needed to cover the living room
One roll costs $15.90
6 rolls * 15.90 = $95.40

solve the following system x=2 5x+4y=-22
Answer:
x = 2
y = -8
Step-by-step explanation:
Since it already gives you x, all you need to do is plug it into the equation:
5x + 4y = -22
5(2) + 4y = -22
10 + 4y = -22
Then, subtract 10 from both sides:
10 + 4y = -22
- 10 - 10
__________
4y = -32
Finally, divide both sides by 4:
4y = -32
y = -8
So now you have, x = 2 and y = -8
Answer:
X=2
5x +4y= -22
5(2)+4y = -22
10+4y= -22
4y= -22-10
4y= -32
Y= -8
The answers are :
X = 2
Y = -8

To reach a particular department at a warehouse, a caller must dial a 4 4 -digit extension. Suppose a caller remembers that the first and last digits of an extension are 5, 5 , but they are not sure about the other digits. How many possible extensions might they have to try? Enter your answer as a number, such as: 425
Answer:
100
Step-by-step explanation:
just took the test
The caller must consider 10 possibilities for each of the two unknown digits in the 4-digit extension. Since the first and last digits are confirmed as 5, there are 10 x 10 = 100 possible extensions they might have to try.
To calculate the number of possible extensions the caller might have to try, we can look at the structure of the 4-digit extension. Given that the first and last digits are known to be 5, the caller is unsure about the second and third digits.
Each of the unknown digits can be any number from 0 to 9. Since there are 10 possibilities for each of these two positions (the second and third digits), to find the total number of combinations, we multiply the possibilities for each digit.
The calculation is as follows:
Number of possibilities for the second digit = 10 (0-9)
Number of possibilities for the third digit = 10 (0-9)
Therefore, the total number of possible extensions is:
10 (possibilities for the second digit) imes 10 (possibilities for the third digit) = 100 possible extensions.

225.85
Answer: Albert's gross pay for this pay period is $384.75
Step-by-step explanation:
Given : Albert's hourly pay is $8.10
His hourly pay is $12.15 when he work more than 40 hours
Last week working hours = 45 hours
Therefore
For first 40 hours he got $8.10 hourly and for more 5 hours he got $12.15 hourly
So
Pay of first 40 hours = [tex]40 \times 8.10[/tex] = $324
Pay for next 5 hours= [tex]5 \times 12.15[/tex] = $ 60.75
Total Gross pay = $324+$ 60.75 =$384.75
Hence , Albert's gross pay for this pay period is $384.75

the answer would be 11 out of 30 because there is 11 boys in total and the total of boys and girls is 30 so the answer is 11 out of 30
The probability that a randomly selected person who can bike to school is a boy is 7/16 or 0.4375, which means there is a 43.75% chance that the person is a boy.
Explanation:To determine the probability that a randomly selected person who can ride a bike to school is a boy, we will use the provided data.
Looking at the data table, we can see there are 7 boys who can bike to school, and the total number of students who can bike to school is 16 (this is the sum of boys and girls who can bike). In probability terms, the boys who can bike are the 'favorable outcomes' and the total students who can bike are the 'possible outcomes'.
Probability is calculated by dividing the number of favorable outcomes by the number of possible outcomes. Thus, the probability a randomly selected person can ride a bike to school is a boy is 7/16, or approximately 0.4375.
This means, if we were to randomly select a person who can bike to school, there is a 43.75% chance that the person is a boy. I hope this explanation helps explain how to determine probability using a data set.

A new printer can print a batch of newsletters twice as fast as an older printer. With both printers working together, the newsletters can be printed in 45 minutes. How long would it take the newer printer working alone?
Answer:
It would take 1 hr, 7 min, 30 sec for the newer printer to work alone.
Step-by-step explanation:
x/1.5=45
45*1.5=67.5 minutes
67.5 minutes = 1 hr, 7 min, 30 sec
Final answer:
The time it would take for the new printer working alone to print a batch of newsletters is 67.5 minutes. This is determined by setting up an equation based on the combined work rates of the new and old printers.
Explanation:
The student is asking how long it would take for a new printer, which can print twice as fast as an older printer, to complete printing a batch of newsletters on its own if both printers can finish the task together in 45 minutes. This question involves setting up and solving a problem related to rates of work.
Let's denote the time it takes for the new printer to print the newsletters alone as T minutes. Since the new printer works twice as fast as the old printer, the old printer would take 2T minutes to do the job alone. When working together, they can finish the task in 45 minutes.
We can set up the equation based on their combined work rates like this:
1/T (new printer's rate) + 1/(2T) (old printer's rate) = 1/45 (combined rate).
Let's solve for T:
Calculate the combined rate of the printers: 1/T + 1/(2T) = 1/45
Combine the fractions on the left side: (2 + 1) / 2T = 1/45
Simplify the fraction to get a common denominator: 3 / 2T = 1/45
Cross-multiply to solve for T: 3 * 45 = 2T
Calculate T: 135 = 2T
Divide both sides by 2: T = 135 / 2
Finish solving: T = 67.5
Therefore, the new printer working alone would take 67.5 minutes to print the batch of newsletters.
One employee pours 6 ounces of coffee in the large frappuccino.
Does this follow the instructions above? Why or why not?
Answer:
The employee's action is not following the instructions.
Step-by-step explanation:
The drinks table has some recommendations to make some drinks exclusive to the establishment such as the Large Frapuccino or the Small Chai Tea, which in its first line corresponding to the Large Frapuccino specifies that at least 8 ounces of coffee should be used, which it wants to say is the minimum amount of coffee that can be added to it is 8 ounces, and the value could be higher than that, but never lower, which is why by adding only 6 ounces to the Frapuccino you are totally ignoring the instructions.

What is the x-value of point A?
Answer: 5
Step by Step Explanation:
Consider the diagram below where measure of angle CDE=127 degrees.
Select all of the statements that are true.
A. measure of angle EDF=53 degrees
B. measure of arch EGD=127 degrees
C. measure of arch ED=106 degrees
D. measure of angle GAE=53 degrees
E. measure of arch EGD=254 degrees
The statements A and D are true.
Based on the diagram, here are the true statements:
A. measure of angle EDF=53 degrees:
This is true because angle EDF and angle CDE are supplementary angles, meaning they add up to 180 degrees.
Since we're given that measure of angle CDE=127 degrees, we can find measure of angle EDF by subtracting 127 from 180:
measure of angle EDF = 180 degrees - 127 degrees = 53 degrees.
D. measure of angle GAE=53 degrees:
This is true because angle EDF and angle GAE are corresponding angles.
Corresponding angles are pairs of angles that are on opposite sides of a transversal and that share a common endpoint with the transversal.
They are equal in measure.
Since we've already determined that measure of angle EDF=53 degrees, we can conclude that measure of angle GAE=53 degrees as well.
Therefore, the statements A and D are true.

The length of the base of triangle in the given case is 14.28 feet.
What is Pythagoras theorem?Pythagoras theorem states that in a right angled triangle, the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be written as h² = p² + b².
The diagram for the given problem can be shown below,
Here, AB = AC = 10 feet and AD = 7 feet.
Apply pythagoras theorem in ΔABD to get,
AD² + BD² = AB²
Substitute the corresponding values to obtain,
BD² = 10² - 7²
⇒ BD = 7.14
Now, CB = 2 × BD
⇒ CB = 2 × 7.14 = 14.28
Hence, the length of the base is given as 14.28 feet.

Which of the quadratic functions has the narrowest graph?
y = −10x2
y = −0.9x2
y = 9x2
Explanation:
The equation y = ax^2+bx+c has the value of 'a' determine how wide or narrow the graph is. The closer 'a' is to zero, then the wider it gets; while the further 'a' is from 0, the narrower it gets.
What we need to do is look for equations in which the 'a' value is furthest from 0. In this case, it's with y = -10x^2 since a = -10 is furthest from zero compared to a = -0.9 and a = 9. Set up a number line to help see this. You can also use absolute values to get the job as well.
Therefore, y = -10x^2 has the most narrowest graph.

If you invest $100,000 in an account earning 8% interest compounded annually, how long will it take until the account holds $300,000?
(Round to the nearest 0.1 of a year.)
( answergoes here ) ______________________
Compound interest formulas:
A=P(1+rn)ntA=P(1+r/n)^nt and A=Pe^rt
We have been given that you invest $100,000 in an account earning 8% interest compounded annually. We are asked to find the time it will take the amount to reach $300,000.
We will use compound interest formula to solve our given problem.
[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,
A = Final amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
[tex]8\%=\frac{8}{100}=0.08[/tex]
[tex]300,000=100,000(1+\frac{0.08}{1})^{1\cdot t}[/tex]
[tex]300,000=100,000(1.08)^{t}[/tex]
[tex]\frac{300,000}{100,000}=\frac{100,000(1.08)^{t}}{100,000}[/tex]
[tex]3=(1.08)^{t}[/tex]
[tex](1.08)^{t}=3[/tex]
Let us take natural log on both sides of equation.
[tex]\text{ln}((1.08)^{t})=\text{ln}(3)[/tex]
Using natural log property [tex]\text{ln}(a^b)=b\cdot \text{ln}(a)[/tex], we will get:
[tex]t\cdot \text{ln}(1.08)=\text{ln}(3)[/tex]
[tex]\frac{t\cdot \text{ln}(1.08)}{\text{ln}(1.08)}=\frac{\text{ln}(3)}{\text{ln}(1.08)}[/tex]
[tex]t=\frac{1.0986122886681097}{0.0769610411361283}[/tex]
[tex]t=14.274914586[/tex]
Upon rounding to nearest tenth of year, we will get:
[tex]t\approx 14.3[/tex]
Therefore, it will take approximately 14.3 years until the account holds $300,000.

Answer:
3,655.21
Step-by-step explanation:
The amount that Larry owes on his debt after 2 years is $20,514.
What is compound interest?The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.
Given information is for monthly compounding as below,
The accumulated money in credit card is, P = $3000.
The rate of interest is 10% per year.
Then, the rate of interest per month is, r = 10/12 = 5/6%.
The time for compounding in years is 2 years.
Then in months, n = 2 × 12 = 24 months.
The formula for amount in compound interest is given as,
A = P(1 + r/100)ⁿ
Substitute the corresponding values to get,
A = 3000(1 + (5/6)/100)²⁴
= 3000 × 6.838
= 20514
Hence, the amount owed by Larry on the debt after 2 years is $20,514.
