math question down below

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.

Answer:

[tex]2+2=4[/tex]

[tex]\frac{8}{2}=4[/tex]

Step-by-step explanation:

We are asked to write two expressions where the solution is 4.

We can write infinitely many solutions whose solution is 4. Some of the expressions are as follows:

[tex]3+1=4[/tex]

[tex]2+2=4[/tex]

[tex]\frac{8}{2}=4[/tex]

[tex]\frac{16}{4}=4[/tex]

[tex]8-4=4[/tex]

[tex]6-2=4[/tex]

[tex]2\cdot 2=4[/tex]

Therefore, all of these expressions satisfy the given condition.

The solution to the equation -7=-1+ x/3 is obtained by adding 1 to both sides, then multiplying both sides by 3 to solve for x. This yields x = -18.

To solve the equation -7=-1+ x/3, we can first isolate the x term using the addition and multiplication properties of equality.

Hence, the solution to the equation -7=-1+ x/3 is x=-18.

what are the options?^

Final answer:

The correct option is (A) 3 1/2 feet. To find the total amount of wood Frank needs for the table legs, multiply the length of one leg (7/8 foot) by 4, the number of legs, resulting in 3 1/2 feet of wood in total.

Explanation:

Frank needs four pieces of wood, each 7/8 of a foot long for the table legs. To find the total amount of wood required, we multiply the length of one piece by the number of pieces:

Multiply the length of one leg, 7/8 foot, by the number of legs, which is 4.
(7/8) foot x 4 = (7/8) x 4/1 = 28/8 = 3.5 feet

Therefore, Frank needs 3 1/2 feet of wood in total for the table legs.

The solution for n is [tex]\( n = \frac{{q - rt}}{{10}} \)[/tex].

To solve for n in the equation -14n + q = rt - 4n, we need to isolate n on one side of the equation.

First, let's gather all terms involving n on one side. Adding 4n to both sides of the equation, we get:

-14n + 4n + q = rt

Simplifying the left side, we have:

-14 + 4)n + q = rt

-10n + q = rt

Next, let's isolate n by moving the term q to the other side. Subtracting q from both sides, we have:

-10n = rt - q

Finally, to solve for n, divide both sides by -10:

[tex]\[ n = \frac{{rt - q}}{{-10}} \][/tex]

So, the solution for n is [tex]n = \frac{{q - rt}}{{10}} \)[/tex].

Answer:

25 meters.

Step-by-step explanation:

Let us suppose each athlete run x km.

Hence, four athlete will run 4x km.

Now, the distance of the relay race is 1/10 km

Thus, we have

[tex]4x=\frac{1}{10}[/tex]

Divide both sides by 4

[tex]x=\frac{1}{40}km[/tex]

Now, 1 km = 1000 meters. Thus, we have

[tex]x=\frac{1}{40}\times1000\\\\x=25[/tex]

Thus, each athlete run 25 meters.

Final answer:

To find the unit rate in miles per hour, divide the distance by the time. In this case, Jon travels at a unit rate of 2 miles per hour.

Explanation:

To find the unit rate in miles per hour, we need to convert the given information into the same units. Jon travels 1/2 mile in 1/4 hour, so we can simplify the fraction to 2/4, which is equal to 1/2. This means Jon travels 1/2 mile every 1/4 hour. To find the unit rate, we divide the distance (1/2 mile) by the time (1/4 hour).

1/2 mile ÷ 1/4 hour = 2 miles per hour

Therefore, the unit rate at which Jon travels is 2 miles per hour.
