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
What is the scale factor
Answer:
1/3
Step-by-step explanation:
33/11=3
so its 1/3 of it
Answer:
1/3
Step-by-step explanation:
If you divide one of the sides in figure A by 3, then you will get the corresponding side for figure B.
So if I divide the uppermost side, which is 33units by 3, I will get the uppermost side in figure B, which is 11units.
Since dividing b 3 is like multiplying by 1/3 then the scale factor is 1/3
Solve the equation for x.

Is ABC = def if so name the postulate that applies
The triangles do not meet the criteria of any postulate, therefore, they might not be congruent.
What are Congruent Triangles?There are criteria that can be used to show that two triangles are congruent to each other. They are:
ASA postulate: This says that two triangles are congruent if they have two pairs of congruent angles and one pair of included congruent sides.SAS postulate: This says that two triangles are congruent is they have two pairs of congruent sides and one pair of included congruent angles.HL postulate: If both triangles have equal hypotenuses and a pair of congruent corresponding legs, then they are congruent triangles based on this postulate.SSS postulate: both triangles are congruent if they have three pairs of congruent sides.However, two triangles can have three pairs of congruent angles and may not necessary be congruent triangles.
The triangles in the image below shows that the two triangles have three pairs of corresponding congruent angles. This information is not enough to prove they are congruent.
The answer is, C. Might not be congruent.

Four brothers each bought two hot dogs and a bag of chips at the football concession stand. If the bag of chips was $1.25, and the total was $18.20, what was the price of one hot dog
Your answer is 1.65.
(may have a hard time explaining it)
SO, there are 8 hotdogs and 4 bags of chips, 4 times 1.25 is 5, and 18.20 minus 5 is 13.20, so the chips are out of the equation. Now all we must do is divide what's left (13.20) by 8:
13.20/8=1.65

Step-by-step explanation:
The solutions to the equation 2x2+x-1=2 are x=-3/2 or x=_
Answer:
the solutions are {1, -3/2}
Step-by-step explanation:
The given equation 2x^2 + x - 1 = 2 simplifies to 2x^2 + x - 3 = 0 if we subtract 2 from both sides.
We are told that -3/2 is a solution and must find the other solution To do this, use synthetic division; if the remainder is zero, that tells us that -3/2 is actually a solution, and we can obtain the second solution easily, as follows:
-3/2 / 2 1 -3
-3 3
-------------------------
2 -2 0
Since the remainder is 0, we have verified that -3/2 is a solution. The coefficients of the other factor of the original equation are 2 and -2, and so this other factor is 2x - 2, or 2(x - 1). Setting this result equal to zero yields x = 1.
Thus the solutions are {1, -3/2}.

Jason’s camp counselor job pays a lower hourly rate than Mia’s lifeguard job.
Answer:
Jason's job pays a higher hourly rate than Mia's lifeguard job.
Step-by-step explanation:
It tells that Jason gets paid $9/hour
now divide each amount Mia makes by the number of hours each day and you get the same amount of $8.75/hour.
what is the greatest common factor shared by 10 and 40
[tex]\huge\bold\green{Answer:-}[/tex]
Greatest common factor (GCF) of 10 and 40 is 10.
GCF(10,40) = 10
[tex]\huge\bold\red{Explanation:-}[/tex]
We will now calculate the prime factors of 10 and 40, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 10 and 40.
Prime Factorization of 10
Prime factors of 10 are 2, 5. Prime factorization of 10 in exponential form is:
10 = 2¹ × 5¹
Prime Factorization of 40
Prime factors of 40 are 2, 5. Prime factorization of 40 in exponential form is:
40 = 2³× 5¹
Factors of 10
List of positive integer factors of 10 that divides 10 without a remainder.
1, 2, 5
Factors of 40
List of positive integer factors of 40 that divides 10 without a remainder.
1, 2, 4, 5, 8, 10, 20
Greatest Common Factor
We found the factors and prime factorization of 10 and 40. The biggest common factor number is the GCF number.
So the greatest common factor 10 and 40 is 10.
The Greatest Common Factor of 10 and 40 is 5.
What is Greatest Common Factor?The greatest common factor is the largest number that is a factor of two or more numbers (GCF). The greatest number (factor) divides them, yielding a Natural number. Once all of the number's variables have been identified, there are a handful that are shared by both. The greatest common factor is the largest number found among the common factors. The GCF is often referred to as the Highest Common Factor (HCF)
For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
Given:
We have to find the greatest common factor of 10 and 40.
So factorizing each number
10 = 2 x 5
40 = 2 x 2 x 2 x 5
Here the common factor of 10 and 40 is
= 2 x 5
= 10
Thus, the Greatest Common Factor is 10.

Which statement about the ordered pairs (3, -8) and (4, 4) is true for the equation 3x - y/4 = 11?
A. Neither ordered pair is a solution.
B. Both ordered pairs are solutions.
C. (4, 4) is a solution to the equation but not (3, -8).
D. (3, -8) is a solution to the equation but not (4, 4).
Answer:
Neither ordered pair is a solution.
Step-by-step explanation:
If we substitute an ordered pair which is the correct solution, we will obtain the value at the right hand side of the equation.
Now let us try it;
Substitute (3,-8)
3(3)-(-8)/4 = 9 +8/4 =17/4
Again;
3(4) - 4/4 = 8/4 =2
Hence, none of the ordered pairs is a solution.
