Two pulleys, one with radius r 1r1 and the other with radius r 2r2, are connected by a belt. The pulley with radius r 1r1 rotates at omega 1ω1 revolutions per minute, whereas the pulley with radius r 2r2 rotates at omega 2ω2 revolutions per minute. Show that StartFraction r 1 Over r 2 EndFraction equals StartFraction omega 2 Over omega 1 EndFraction r1 r2
Answer:
r1/r2 = 2ω2/ω1
Step-by-step explanation:
The velocity of each pulley is expressed as v = ωr where;
v is the linear velocity of the pulley
ω is the angular velocity of the pulley
r is the radius of the pulley.
For the two pulleys, the velocity I'd both pulleys are the same.
v1 = v2
v1 is the linear velocity of first pulley
v2 is the linear velocity of the second pulley.
v1 = ω1r1
v2 = 2ω2(r2)
r1 and r2 is the radius of pulley 1 and pulley 2 respectively.
Since v1 = v2
ω1r1 = 2ω2(r2)
Divide both sides by r2
ω1r1/r2 = 2ω2(r2)/r2
ω1r1/r2 = 2ω2
Divide both sides by ω1
ω1r1/r2/ω1= 2ω2/ω1
r1/r2 = 2ω2/ω1

F&J Farms sells super egg-laying chickens that historically weigh on average 3 pounds with a standard deviation of 0.4 pounds. However, it has been discovered that the chickens actually weigh twice as much as they used to. What is actual the mean and standard deviation of the chickens?
Answer:
Mean of chicken = 6 pounds, Standard Deviation of chicken = 0.6 pounds
Step-by-step explanation:
Given : Chickens mean & standard deviation = 3 & 0.4 pounds respectively. Chickens considered weigh twice actually now.
If all numbers in the series are multiplied by a constant, the mean gets multiplied by that constant. So, new mean = 3 x 2 = 6
If all numbers in the series are multiplied by a constant, the standard deviation gets multiplied by that constant. So, new standard deviation = 0.4 x 2 = 0.8

Answer:
a. height = 12
b. area = 228
Step-by-step explanation:
a. To find the height, we can use the triangle formed by the side that measures 15, the side that measures 9. and the height. The hypotenuse of the triangle(the longest side opposite of the right angle), is 15. We can then use the Pythagorean Theorem, which states that [tex]a^2+b^2=c^2[/tex], where c is the hypotenuse, and a and b are the two other sides. In this case, we need to find a leg of the triangle, not the hypotenuse. What do we do? We can first call the height a, and rearrange the Theorem into [tex]c^2-b^2=a^2[/tex]. [tex]15^2=225, 9^2=81,[/tex] and [tex]225-81=\sqrt{144}[/tex]=12. Therefore, the height of the parallelogram is [tex]\boxed{12}[/tex]
b. To find the area of the parallelogram, we can use the area formula, which is Base*Height. The base is the flat side. We can find the base by adding 9+10=19, and [tex]19\cdot12=\boxed{228}[/tex]

Harry put blue and green marbles in a bag. Exactly 3/4 of the marbles in the bag are blue. Which of the following could be the total number of marbles in the bag.
A. 3
B. 6
C. 7
D. 8
Answer:
D
Step-by-step explanation:
Because when u multiply 3/4 times A,B,C it gives you a decimal, when u multiply 3/4 by 8 you get 6 a whole number.
The total number of marbles in the bag could be (d) 8
How to determine the possible total?We have:
Blue proportion = 3/4
This means that the green proportion is
Green proportion = 1 - 3/4
Evaluate
Green proportion = 1/4
Express as ratio
Blue: Green = 3/4 : 1/4
Simplify
Blue: Green = 3 : 1
Add the ratios
Total = 3 + 1
Total = 4
The above means that the total number of marbles in the bag is a multiple of 4
i.e. 4, 8, 12, 16, 20......
Hence, the total number of marbles in the bag could be (d) 8

find the value of X for which m is parallel to n .
Answer:
x = 42
Step-by-step explanation:
the angles are considered congruent so the equation would be 4x-27 = 3x+15
add 27 to both sides: 4x= 3x +42
subtract 3x from both sides: x= 42

Bethany is playing a game with her sister. Each player starts with 3 shuffled decks of cards turned upside down in 3 separate
piles so they don't know what order the cards are in. At each turn they draw 2 cards, 1 from the top of 2 piles of their
choosing
Bethany has the last play, and to win the game, she needs 2 face cards. She has paid attention to which cards have been
played from each pile, and she knows what cards are remaining in each pile. The cards remaining in each pile are shown
below.
Pile 1 = (10C, 5D, 9H, 9D, JD, 8D)
Pile 2 - (8D, QC, 45, 4D, AD, JS, 4H)
Pile 3 = {4C, KS, 6S, 10D, 4H}
Which 2 piles should Bethany draw from to have the best chance of winning the game?
Note: The last letter in the lists above gives the suit: Club, Diamond, Heart, or Spade. The first number or letter is the card
value. Jacks, Queens, and Kings are face cards.

Bethany is playing a game with her sister,

At each turn they draw 2 cards, 1 from the top of 2 piles of their
choosing
Which 2 piles should Bethany draw from to have the best chance of winning the game = ?
Following combination of piles should be selected:-
Pile 1, has 2 face cards (Jack of Diamonds, Queen of Clubs) and pile 2 has 2 face cards (Jack of Spades, Ace of Diamonds), so by drawing from these two piles, Bethany has a total of 4 face cards to choose from.Pile 3 only has 1 face card (King of Spades), so drawing from this pile alone would give her a lower chance of winning the game.To have the best chance of winning the game, Bethany should draw from piles 1 and 2.

the perimeter of the triangle below is 38 units. Find the length of side WX. Write your answer without variables
Answer:
5.5
Step-by-step explanation:
Add each side of the triangle.
3z+z+1+4z-3 = 8z - 2
8z - 2 is equivalent to the perimeter.
Since you know the perimeter is 38 units, you can set 8z-2 to 38.
8z-2 = 38
Solve for z. Subtract 2 from each side.
8z = 36
Divide each side by 8.
z = 4.5
Now solve for side WX.
WX = z + 1
WX = 4.5 + 1
WX = 5.5
