Frank is building a table. He needs 4 pieces of wood for the table legs. Each piece of wood needs to be 7/8 of a foot long. What is the total amount of wood he needs for the legs?
A. 3 1/2 feet
B. 3 2/5 feet
C. 4 4/7 feet
D. 4 7/8 feet
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.

How to write 75 1/3 % as a fraction in simplest form
Answer:
The simplified form of the provided fraction is [tex]\frac{226}{3}\%[/tex].
Step-by-step explanation:
Consider the provided fraction.
The provided fraction can be written as:
[tex]75\frac{1}{3}\%[/tex]
Convert the provided mixed number into a proper fraction.
Multiply the number 75 with 3 and add 1 to the obtained number.
[tex]75\frac{1}{3}\%[/tex]
[tex]\frac{(75\times 3+1)}{3}[/tex]
[tex]\frac{225+1}{3}\%[/tex]
[tex]\frac{226}{3}\%[/tex]
Hence, the simplified form of the provided fraction is [tex]\frac{226}{3}\%[/tex].
To convert 75 1/3 % to a fraction in simplest form, first change the mixed number to an improper fraction, then write it over 100, and finally simplify by dividing both numerator and denominator by their greatest common divisor.
Explanation:To convert 75 1/3 % to a fraction in simplest form, start by understanding that a percent is a ratio whose denominator is 100. Therefore, 75 1/3 % can be expressed as the fraction 75 1/3 over 100.
First, convert the mixed number to an improper fraction. Multiply the whole number 75 by the denominator 3 and add the numerator 1:
75 * 3 = 225225 + 1 = 226Now, 75 1/3 as an improper fraction is 226/3. Write this as a fraction over 100:
226/3 % = (226/3) / 100 = 226/300
To simplify this fraction, we look for the greatest common divisor of 226 and 300, which is 2. Divide both the numerator and the denominator by 2 to get:
Numerator: 226 / 2 = 113Denominator: 300 / 2 = 150The fraction in simplest form is therefore 113/150.

or
40 divided by 5 - 4 = 4
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]

-7=-1+ x/3
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.
Explanation:To solve the equation -7=-1+ x/3, we can first isolate the x term using the addition and multiplication properties of equality.
First, add 1 to both sides to cancel out -1 from the right side of the equation. This gives us -6= x/3. Then, multiply both sides by 3 to solve for x. This gives us -18=x.
Hence, the solution to the equation -7=-1+ x/3 is x=-18.

A relay race is 1/10 kilometer long. Four athletes will run an equal distance to complete the relay. How far does each athlete run ?
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.

While trying to explain a physics concept, a student said, "Stuff keeps doing what it's doing unless something messes with it." What law was the student summarizing? Explain your answer.
Your answer
When a soccer player kicks a ball, the ball accelerates. Explain what causes this acceleration in terms of forces.
Your answer
Describe three examples from sports in which a force changes the velocity of an object or a person.
Your answer
Explain which has greater inertia; a speeding car or a jet airplane sitting on the runway.
Your answer
Do forces always cause motion, explain?
Your answer
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.

Jon travels 1/2 mile in 1/4 hour. Find the unit rate in miles per hour.
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.
