Answer:
Step-by-step explanation:
1. Newton's first law of motion: Also called the law of inertia, states that "An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force"
2. According to Newton's second law "the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a)", meaning that when the soccer player kicks a ball, a force is acting on the ball, therefore increasing it's acceleration. After the force is applied, the gravity and the resistance of air will be the ones in charge of stopping the ball.
3. a) Baseball: The ball changes direction and speed when it's hit with the bat.
b) Bowling: When the ball hits the pins, the change from being at rest to a higher velocity.
c) Wrestling: The wrestler exerts a force on the oponent increasing or decreasing it's velocity.
4. The jet airplane has more inertia. Inertia is the resistance of an object to move if at rest, or to change its velocity and it is proportional to the mass of the object. Therefore, the jet airplane being heavier than the car will have more inertia. It has to be clear that it is not due to the fact that is at rest that is the one with more inertia, but mostly related to the mass. If the example was with two cars, one at constant velocity and the other at rest, both with the same mass, the one with greater inertia will be the one moving.
5. No, forces do not always cause motion. They have to be greater than the forces that oppose movement, such as friction, air resistance or gravity.

1. Choose the equation you can use to solve the following problem.
Each cupcake costs $4.00. How many cupcakes, x, are purchased if the total cost is $36.00?
(1 point)
2. Choose the equations you can use to solve the following problem.
Sam is 3 years younger than Marco. Marco is 15 years old. How old is Sam?
Let x represent Sam's age, in years.
(2 points)
3. The equation below represents how many hours, x, it will take to travel 210 miles at an average speed of 60 miles per hour.
How long will it take? 60x210
Final answer:
To solve the given problems, use linear equations: for cupcakes, 4x = 36; for Sam's age, x = 15 - 3; and for travel time, 210 = 60x.
Explanation:
1. To find how many cupcakes, x, can be purchased for $36.00 when each cupcake costs $4.00, we use the equation 4x = 36. This equation represents the cost of cupcakes multiplied by the number of cupcakes equals the total cost.
2. For determining Sam's age, given that Sam is 3 years younger than Marco, who is 15 years old, we represent Sam's age with x. The equation to calculate Sam's age would be x = 15 - 3.
3. The equation presented as 60x210 seems to be a mistake. To find out how many hours, x, it will take to travel 210 miles at an average speed of 60 miles per hour, the correct equation is 210 = 60x.
the backpacking Club is having some posters printed the printer charges $180 plus 250 per poster how many posters can be printed for $1,000 please explain
To find out how many posters can be printed for $1,000, we need to set up an equation and solve for 'x'. The cost of printing 'x' posters is $180 plus $250 per poster. After solving the equation, we find that 3 posters can be printed for $1,000.
Explanation:To find out how many posters can be printed for $1,000, we need to set up an equation.
Let's say the number of posters is 'x'. The cost of printing 'x' posters is $180 + $250 * 'x'.
We want to find out when the cost equals $1,000, so we can set up the equation: 180 + 250 * 'x' = 1000.
To solve this equation, subtract 180 from both sides and then divide by 250. This will give us the value of 'x', which represents the number of posters that can be printed for $1,000.
Once you solve the equation, you will find that 'x' is equal to 3.2. However, since you cannot print a partial poster, we can conclude that 3 posters can be printed for $1,000.

Identify a temperature colder than -7.2f. Write an inequality that relates the temperatures. Describe their positions on a horizontal number line.
A temperature colder than -7.2°F can be -8°F. The inequality representing this is -8 < -7.2. Drawing this on a number line shows -8 is to the left of -7.2, hence colder.
Explanation:A temperature that is colder than -7.2°F could be -8°F. The inequality that relates -8°F and -7.2°F is -8 < -7.2, because on a number line, numbers to the left are lesser than those to the right. Therefore, -8°F, being to the left/less than -7.2°F on the horizontal number line, is colder.
The Fahrenheit and Celsius temperature scales don't have absolute lowest temperatures like the Kelvin scale. So, temperatures like -10°F or -20°F (for example) are possible and would be colder than -7.2°F.

Give the coordinates of the point located halfway between (2,1) and (2,4)
The coordinates of the mid - point are - M(2, 2.5).
We have two coordinate points - A(2, 1) and B(2, 4)
We have to find the midpoint of this line AB.
What is Mid - Point Theorem?It states that a line with endpoint coordinates as - [x(1), y(1)] and [x(2), y(2)] has its mid - point at the coordinates -
x(m) = [tex]$\frac{x(1)+x(2)}{2}[/tex]
y(m) = [tex]$\frac{y(1) + y(2)}{2}[/tex]
According to question, we have -
First coordinate Point - A(2, 1)
Second coordinate Point - B(2, 4)
Using the Mid - Point formula, we get -
x(m) = [tex]$\frac{x(1)+x(2)}{2} = \frac{2+2}{2} =2[/tex]
y(m) = [tex]$\frac{1+ 4}{2}=2.5[/tex]
hence, the coordinates of the mid - point are - M(2, 2.5).
