its honestly sad seing people hungry for points anyways enjoy your answer
Elastic energy, such as a stretched archery bow is not an example of kinetic energy.
What is Energy?Energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
Energy are of two types:
Potential Energy
Kinetic energy
potential energy, stored energy that depends upon the relative position of various parts of a system
Kinetic energy is the energy an object has because of its motion.
In the given options, Elastic energy, such as a stretched archery bow is not an example of the kinetic energy. because a stretched bow is potential energy because the arrow is not moving but stretched holding potential energy for it to be released to its target.

The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Answers
Answers:
team one = 162team two = 108=========================================================
Explanation:
The ratio 3:2 scales up to 3x:2x for some positive whole number x.
This tells us that the first team has 3x people and the second team has 2x people. We'll subtract 12 from the first team and add 12 to the second team to represent 12 people moving.
3x becomes 3x-122x becomes 2x+12The new team counts 3x-12 and 2x+12 represent team 1 and team 2. Those expressions are in the new proportion 5:4.
This means....
(team 1 new count)/(team 2 new count) = 5/4
(3x-12)/(2x+12) = 5/4
4(3x-12) = 5(2x+12)
12x-48 = 10x+60
12x-10x = 60+48
2x = 108
x = 108/2
x = 54
From this, we then can say:
team 1 original count = 3x = 3*54 = 162team 2 original count = 2x = 2*54 = 108The two subtotals add to 162+108 = 270 players overall.
If we were to subtract 12 from team 1, and add 12 to team 2, then,
team 1 new count = 162-12 = 150team 2 new count = 108+12 = 120The ratio 150:120 then reduces to 5:4 when we divide both parts by the GCF 30. This helps confirm we have the correct answer.
Answer:
162 athletes108 athletesStep-by-step explanation:
Each ratio can be expressed using two numbers that have the same sum. The sum in the first given ratio is 3+2 = 5, and in the second ratio, it is 5+4 = 9. The least common multiple of 5 and 9 is 45, so we can express both ratios so they have a sum of 45:
3 : 2 = 3(9) : 2(9) = 27 : 18
5 : 4 = 5(4) : 4(5) = 25 : 20
Here, we observe that the second ratio has numbers that look like 2 was moved from the numerator to the denominator. (27 -2 = 25; 18 +2 = 20) The problem statement tells us 12 athletes were moved, so multiplying the first ratio by 12/2 = 6 will tell us the numbers of players on each original team:
first team = 27×6 = 162 athletes
second team = 18×6 = 108 athletes
A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . Write an equation for the monthly payment a customer pays according to the new plan . Use y for monthly payment , and x for international minutes.
Type the equation in the form y=ax+b without using any spaces. Write any decimals in the form 0.00
Answers
Answer:
y = a(.10) + 25
Step-by-step explanation:
Using the equation y = ax + b.
"$25 per month for unlimited calls in the country and $0.10 per minute for international calls."
The word "per" indicating that you are multiplying this.
The only variables being multiplied are a and x.
Thus, a is the amount of minutes, x is the cost of international calls and b is the cost of unlimited calls.

1 unit

3 units
5 units
Answers
Answer:
The correct option is C.
Step-by-step explanation:
It is given that line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A'B'.
Translation is a rigid transformation. It means the shape and size of preimage and image are same. In other words we can say that the preimage and image are congruent.
Corresponding sides of congruent figures are congruent.
The length of A'B' is 3 units. Therefore the correct option is C.
