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

Answers

Answer 1

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

FIND THE DISTANCE BETWEEN EACH PAIR OF POINTS. ROUND TO THE NEAREST TENTH. (-4, 5) (4, 0)

Answers

Answer:

+9.4 to the nearest tenth

Step-by-step explanation:

(-4, 5) (4, 0)

Refering to the x-coordinates and the y-coordinates of these two points, we see that x changes from -4 to 4, a change of 8, which forms the horizontal leg of a right triangle.  Simultaneously, y changes from 5 to 0, a change of 5, which forms the vertical leg.  Now use the Pythagorean Theorem to determine the length of the hypotenuse of this triangle; this hypotenuse is the distance between the two points:

distance = +sqrt(8^2 + 5^2) = +sqrt(64 + 25) = + sqrt( 89) = +9.43 to the nearest hundredth and +9.4 to the nearest tenth.

Francisco and Stu were working on simplifying the following polynomial: 4x(2x-3)-5(3x-4). Write the equivalent expression that Francisco and Stu found for the polynomial in standard form?

Answers

Answer: 4x + 3x + 2x - 4 - 3

Step-by-step explanation: The numbers that have an X are considered major than normal numbers , when three numbers have the same X you put first the one that is major . Hope this helped.

The  equivalent expression that Francisco and Stu found for the polynomial in standard form should be considered as the 4x + 3x + 2x - 4 - 3.

Calculation of the equivalent expression:

Since the polynomial is 4x(2x-3)-5(3x-4)

Here the number that should have an X that should be relevant majorly as compared to the normal numbers so here the three numbers should be the similar also X we put first as major.

Therefore, The  equivalent expression that Francisco and Stu found for the polynomial in standard form should be considered as the 4x + 3x + 2x - 4 - 3.

Answers

Answer:

D. 20°      Can I get brainliest please :)

Step-by-step explanation:

You can see their is a 90° angle, and angles across from each other are equal so them together is 180° and you know the whole thing is 360° so you can do

360°-180°=180°

then you have the x's we still know that angles opposite each other are the same so if we add all those angles together we get

x+x+2x+30°+2x+30°

simplify it

6x+60°

then we know what we have left is 180° so we do numbers to numbers

180°-60°=120°

now we have

6x=120°

simplify it

x=20°

The value of x is 20°. Option b is correct.

Value of angle x is to be determine.

What is angle?

it can be defined as the measure of one line tilt over other line.


Here, the sum of angle is 180°
x+90+2x+30=180
3x =180-120
3x =   60
 x = 20

Thus, the value of x is 20°.

on sunday Danielle is having her friends over for her 9th birthday she had 24 M&M bags 36 jelly beans and 48 snickers to make goodie bags If each person coming to her party received the same amount of each candy what is the greatest number of friends that can come over how much candy will they receive PLS help due in 20 minutes

Answers

Number of M&M bags with Danielle = 24

Number of jelly beans with her = 36

Number of snickers with her = 48

To find the highest number of candies each friend of Danielle will get, in a way in which all of them have the same number of candies , we have to find the HCF (highest common factor) of all the varieties of candy with Danielle.

Factors of 24 = 1,2,3,4,6,8,12,24

Factors of 36 = 1,2,3,4,6,9,12,18,36

Factors of 48 = 1,2,3,4,6,8,12,16,24,48

Highest common factor = 12

Which means the highest number of friends Danille can invite is 12 .

Number of M&M bags each friend will get :-

[tex] = 24 \div 12[/tex]

[tex]\color{hotpink} = 2 [/tex]

Which means each friend will get 2 M&M bags .

Number of jelly beans each friend of hers will get :-

[tex] = 36 \div 12[/tex]

[tex]\color{hotpink} = 3[/tex]

Which means each friend of Danielle will get 3 jelly beans.

Number of snickers each friend of hers will get :-

[tex] = 48 \div 12[/tex]

[tex] \color{hotpink}= 4[/tex]

Which means each friend of hers will get 4 snickers .

Therefore , the highest number of friends Danielle can invite = 12 and each of her friends will get 2 M&M bags , 3 jelly beans and 4 snickers .

A packaging company makes package peanuts in two containers, rectangular prisms and cylinders. The rectangular prism has a length of 6 feet, a width of 3 feet, and a height of 5 feet. The cylinder of peanuts has a diameter of 7 feet and a height of 10 feet. How many rectangular prisms contain the same amount of peanuts as one cylinder container? Round your answer to the nearest tenth.

Answers

Answer:

4.3

Step-by-step explanation:

length = 6 feet

width = 3 feet

height = 5 feet

Volume of rectangular prism = length × width × height

= (6 × 3 × 5) feet

= 90 cubic feet

cylinder of peanuts has a diameter of 7 feet and a height of 10 feet

Volume of a cyclinder = πr^2h

π = 3.14

r = diameter / 2

= 7/2 = 3.5 feet

h =10 feet

Volume of a cyclinder = πr^2h

= 3.14 × (3.5)^3 × 10

= 3.14 × 12.25 × 10

= 384.65 cubic feet

How many rectangular prisms contain the same amount of peanuts as one cylinder container = volume of cylinder container / volume of rectangular prism container

= 384.65 / 90

= 4.274

To the nearest tenth = 4.3
