Cylinders A and B are similar solids. The base of cylinder A has a circumference of 4pi units. The base of cylinder B has an
area of 9pi units.
The dimensions of cylinder A are multiplied by what factor to produce the corresponding dimensions of cylinder B?
4/9 2/3 3/2 9/4
Answers
Answer:
d) 9/4
Step-by-step explanation:
Explanation:-
Given circumference of cylinder A = π r² = 4π units
Given circumference of cylinder B = π r² = 9π units
The dimensions of cylinder A are multiplied by [tex]\frac{9}{4}[/tex]
circumference of cylinder A = π r² = 4π([tex]\frac{9}{4})[/tex] units = 9 π units
circumference cylinder A= 4π([tex]\frac{9}{4})[/tex] units = 9 π units = circumference of cylinder B
Final answer:-
The dimensions of cylinder A are multiplied by 9/4 produce the corresponding dimensions of cylinder B

Answer:
58.9 ft²
Step-by-step explanation:
The horse is constrained to 3/4 of a circle that has a 5 ft radius. Then the area is ...
A = (3/4)πr²
A = (3/4)π(5 ft)² = 75π/4 ft²
A ≈ 58.9 ft²
The horse has a maximum grazing area of 58.9 ft².
_____
In the real world, a 5 ft rope is awfully short. The grazing area would depend on how high on the barn it is tied, and where on the horse it is tied.

A football is kicked from the ground and follows the graph of the function y = –t2 + 3t, where y represents height and t represents seconds. At the same time, a drone is launched from a height of 4 feet and follows the straight path of y = –t + 4. At what time are the football and the drone at the same height?
Options:
A. 2 seconds
B. 3 seconds
C. 1 second
D. 5 seconds
Answers
Answer:
The height of the objects are the same after 2 seconds.
Step-by-step explanation:
In order to calculate at which time both objects have the same height we need to find the value of t that makes both equations equal. Therefore:
[tex]-t^2 + 3t = -t + 4\\t^2 - 3t - t + 4 = 0\\t^2 - 4t + 4 = 0\\t_{1,2} = \frac{-(-4) \pm \sqrt{(-4)^2 - 4*1*4}}{2*1} = \frac{4 \pm \sqrt{16 - 16}}{2}\\t_{1,2} = \frac{4}{2} = 2[/tex]
The height of the objects are the same after 2 seconds.

B: f(x) 1/2x + 6 IS THE RIGHT ANSWER .
I ONLY POST THE RIGHT ANSWERS TO THESE Qs PEOPLE !!
Answers
Answer:
f(x) = (1/2)*x + 6
Step-by-step explanation:
We have the following equation:
y - 8 = (1/2)*(x - 4)
Applying distributive property:
y - 8 = (1/2)*x - (1/2)*4
y - 8 = (1/2)*x - 2
Isolating y:
y = (1/2)*x - 2 + 8
y = (1/2)*x + 6
When we talk about functions, y and f(x) refers to the same. So, we can rewrite the last equations as:
f(x) = (1/2)*x + 6

Translate f(x) = |x| so that it's translated down by 3 units and vertically stretched by a factor of –2. What's the new function in terms of g(x)?
A. g(x) = |x| – 3
B. g(x) = |x – 2| – 3
C. g(x) = 3|x + 2|
D. g(x) = –2|x| – 3
Answers
The -3 is the vertical shift 2 units down
The -2 is multiplied outside of the x, so it’s a vertical stretch.
Suppose that a company claims that its chocolate bars weigh 2.8 oz on average. It took many large samples, and each time the mean weight of the sample was within the 95% confidence interval. Which of the following would be a reasonable conclusion.
A) The bars do not weigh 2.8oz on average.
B) The bars weigh fewer than 2.8oz on average.
C) The bars weigh 2.8oz on average.
D) The bars weigh more than 2.8oz on average.
Answers
Answer:
C) The bars weigh 2.8oz on average.
Step-by-step explanation:
The fact that each sample's mean weight was within the 95% confidence interval suggests that the true mean weight of the chocolate bars is likely to be around 2.8 oz. The 95% confidence interval means that, in theory, if we repeated this sampling process many times, we would expect the true mean weight of the chocolate bars to fall within this interval 95% of the time. Since each sample's mean weight falls within this interval, it is reasonable to conclude that the company's claim that the bars weigh 2.8 oz on average is likely to be true.

Which of these values represents the largest distance?
A. 5,000 inches
B. 0.5 miles
C. 5,000 feet
D. 500 yards
Answers
Answer:C 5000 feet
Step-by-step explanation:It’s slightly less then a mile.
Answer:
C. 5,000 feetStep-by-step explanation:
First of all, you would want to convert all of the distances into the same units.
Let's convert the distances to miles.
5,000 inches = about 0.08 miles
0.5 miles = 0.5 miles
5,000 feet = about 0.9 miles
500 yards = about 0.3 miles
Now, we compare the values.
We can easily place 5,000 inches last, because when converted to miles it's 0.08.
0.08<0.3<0.5<0.9
5,000 inches<500 yards<0.5 miles<5,000 feet
Hence, the answer is C.

A microscope dilates the image of an organism 4 times its original dimensions. If the radius of a circular organism seen by the microscope is 8 cm, find the radius of the actual organism. Question 17 options: A) 4 cm B) 8 cm C) 2 cm D) 32 cm
Answers
Answer: 2cm
Step-by-step explanation:
From the question, we are informed that a microscope dilates the image of an organism 4 times its original dimensions and that the radius of a circular organism has seen by a microscope is 8 cm.
Since the microscope makes the objects 4 times bigger, then the original radius will be:
= 8cm/4
= 2cm
The radius of the actual organism is 2cm.

Answer:
Answer is B
Step-by-step explanation:
The hypotenuse of a triangle is always twice the length of the shorter side in a 30 60 90 triangle. So if the hypotenuse is 4 the shortest side must be 2. Meaning the sum will be 6. The medium side is the shortest side times the square root of 3. So we have 2[tex]\sqrt{3}[/tex]. Our final equation is 6+ 2[tex]\sqrt{3}[/tex].

StartFraction 5 over 16 EndFraction StartFraction 3 over 8 EndFraction One-half StartFraction 11 over 16 EndFraction
Answers
Answer:
d
Step-by-step explanation:
The solution is Option D.
The probability of at least two coins landing on heads is given by the equation P = 11/16
What is Probability?
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
The value of probability lies between 0 and 1
Given data ,
Let the probability of at least two coins landing on heads be P
Now , the equation will be
Let the coin landing on its head be represented as = H
Let the coin landing on its tail be represented as = T
The possible outcomes of flipping a coin be represented by set A
Set A = { HHHH , HHHT , HHTH , HHTT , HTHH , HTHT , HTTH , HTTT , THHH , THHT , THTH , THTT , TTHH , TTHT , TTTH , TTTT }
So ,
The total number of outcomes = 16 outcomes
The number of outcomes where at least 2 coins land on their heads is given by set B
Set B = { HHHH , HHHT , HHTH , HHTT , HTHH , HTHT , HTTH , THHH , THHT , THTH , TTHH }
The number of outcomes of set B = 11
So , the probability of at least two coins landing on heads be P = number of outcomes of set B / total number of outcomes
Substituting the values in the equation , we get
Probability of at least two coins landing on heads be P = 11/16
Therefore , the value of P is 11/16
Hence , the probability is 11/16

The factors of 20 are 1,20||| 2,10 |||4,5||||
