Answer:
The average is 6
Explanation:
To find the average, you have to first add all the numbers. After you add all the numbers up, then you divide by how many numbers there are. This one had 4 numbers so you divide by 4
The average snowfall of the four days was 6 inches.
What is snow?
When atmospheric water vapor freeze into small ice crystals and falling in small white flakes or lying on the ground as a white layer, it is called snow.
In the question it is said that,
Amount of snow received by the town on first day = 10 inches.
Amount of snow received by the town on second day = 3 inches.
Amount of snow received by the town on third day = 7 inches.
Amount of snow received by the town on fourth day = 4 inches.
Total amount of snow received by the town on these four days = ( 10 + 3+ 7 + 4) inches.
=24 inches.
Hence, average amount of snow received by the town on these four days = total amount of snow received ÷ 4
= ( 24 ÷ 4) inches.
= 6 inches.
Hence, the average snow received by the little town was 6 inches on those days.

A recipe for a casserole calls for 1 cup of milk. If a chef currently has 0.5 gallons of milk, how many casseroles can the chef make?
Answer:
The chef can make 8 casseroles
Explanation:
Units Conversion
We need to recall 1 gallon = 16 US cups.
A casserole needs 1 cup of milk, and the chef has 0.5 gallons of milk. Those 0.5 gallons are equivalent to 0.5*16 = 8 cups, thus the chef can make 8 casseroles.

Knowing that 1 inch is equal to 2.54 centimeters, convert 287 cm to inches.
Answer: 112.992
Explanation: If you divide 287 by 2.54, you will get 112.992125984. I just got rid of the five numbers after 992.
1 inch = 2.54 cm
?= 287 cm let, ? be (a)
cross multiply
2.54a= 1×287
a= 287/2.54
a= 112.992126
therefore 287 cm = 112.992126 inches.

A planned high-speed train between Houston and Dallas will travel a distance of 386 kilometers in 5.40 × 10^3 seconds. What is the average speed of this train?
¡Hellow!
For this problem, first, lets convert the seconds in hours:
5,4x10³[tex]\rightarrow[/tex] 5400
h = sec / 3600
h = 5400 s / 3600
h = 1,5
Let's recabe information:
d (Distance) = 386 km
t (Time) = 1,5 h
v (Velocity) = ?
For calculate velocity, let's applicate formula:
[tex]\boxed{\boxed{\textbf{d = v * t} } }[/tex]
Reeplace according we information:
386 km = v * 1,5 h
v = 386 km / 1,5 h
v = 257,33 km/h
The velocity of the train is of 257,33 kilometers for hour.
Extra:
For convert km/h to m/s, we divide the velocity of km/h for 3,6:
m/s = km/h / 3,6
Let's reeplace:
m/s = 257,33 km/h / 3,6
m/s = 71,48

Keisha has two large dogs and a small dog. The dogs like to play tug-the-rope together. Each of these three diagrams shows one way that the dogs play together with the rope. Look at each arrow and the number that goes with it. They show the direction and amount of force each dog exerts on the rope. There are three illustrations of two dogs pulling at a toy rope.
The left art should show two big dogs pulling on a rope toy each pulling with a force of 20N in the opposite direction. The middle art shows a big dog on left pulling to the left on the rope toy with a force of 20N and a little dog pulling to the right with a force of 12N. The right art shows the rope toy tied to a post, with both dogs pulling on different parts of the toy and in the same direction. One large dog pulls with a force of 20 N and the small dog pulls with a force of 12 N.
Explain whether the forces shown in each diagram are balanced or unbalanced. Use math-based evidence to support your claim for each diagram.
Answer:
The answer is unbalanced
Explanation:
Though cases like these are not really how the science will be used, they illustrate the principle.
If the left art shows two big dogs pulling on a rope toy each pulling with a force of 20N in the opposite direction. The middle art shows a big dog on left pulling to the left on the rope toy with a force of 20N and a little dog pulling to the right with a force of 12N. The right art shows the rope toy tied to a post, with both dogs pulling on different parts of the toy and in the same direction. One large dog pulls with a force of 20 N and the small dog pulls with a force of 12 N. The atomic theory has been of priceless value to chemists, but it has more than once happened in the history of science that a hypothesis, after having been useful in the discovery Present and the co-ordination of knowledge, has been aban- position doned and replaced by one more in harmony with later of the discoveries
The amount of force exerted in each direction in the rope determines if the force in play is balanced or unbalanced ;
Left art : 20N = 20N (Balanced) Middle : 20N > 12N (Unbalanced) Right art : 20N > 12N (Unbalanced)To determine if the force acting in two direction is balanced or unbalanced, we calculate the net force acting on the object.
The net force = Force 1 - Force 2If the netforce = 0 ; then the force is balanced, if otherwise , then it is unbalanced.
Left art :
Net force = 20N - 20N = 0 NRight art :
20N - 12N = 8N (direction of the 20N force)Middle :
20N - 12N = 8N (direction of the 20N force)Therefore, the value of the net force determines if the force is balanced or not.

A boat sends a sound to the bottom of the ocean and it takes 3 seconds to return to the boat. How deep in the ocean? The speed of sound on water is 1500m/s.
Answer:
2,250 meters deep
Explanation:
If the time taken for the the signal to return to the boat means that it took 3 seconds for the signal to travel to and from the floor the same distance. That means it took 1.5 seconds to travel to the floor at a speed of 1500m/s means that it is 1500 multiplied by 1.5 to a distance of 2,250m. (Derived from the speed = distance divided by time formula to distance = speed multipled by time)
If a force of 20 N is applied to a mass of 5 kg, what is the acceleration?
Answer:
4 m/s^2
Explanation:
To get the acceleration you are going to use the acceleration formula which is
Acceleration= Force/Mass.
You then do the math which is 20/5, which equals 4
Therefore you get a value of 4. You may be asking what the units are. The units of acceleration are m/s^2 (meters per second squared)
So your final answer is 4 m/s^2
A lithium atom has 3 protons, 4 neutrons and 3 electrons. How would the atom change to become a cation? How would the atom change to become an anion?
Answer:
- For the lithium ion to change to become an anion, it will have to gain one or more electrons which can be pulled away from possibly other atoms with a weaker affinity for them.
- For the lithium ion to change to become a cation, it will have to loose one or more electrons which can be drawn by other atoms with a stronger affinity for them.
Explanation:
Generally, an anion has a net negative charge arising from the fact that it has more electrons than protons while a cation has a net positive charge arising from the fact that it has more protons than electrons.
Now, for the lithium ion to change to an anion, it means it has to have more electrons than it's protons. Thus, since it has 3 number each of protons and electrons, it will have to gain one or more electrons which can be pulled away from possibly other atoms with a weaker affinity for them.
Now, for the lithium ion to change to a cation, it means it has to have more protons than it's electrons. Thus, since it has 3 number each of protons and electrons, it will have to loose one or more electrons which can be drawn out by possibly other atoms with a stronger affinity for them.

the force applied to the fist by the piece of oak?
Answer:
The force is 1250-N
Explanation:
Generally according to Newtons third law , which states that for every action there is an equal and opposite reaction
Now considering the question, the action here is the force applied by the ninja while the reaction is the force applied by the oak and from Newton law both of these action are equal but opposite to each other.
Hence the force applied by the the piece of oak on the fist is 1250 N

If a car travels 10 km north and then 10 km west, what is the MAGNITUDE of
displacement?
Answer:
The magnitude of the displacement is [tex]H = 14.14 \ km[/tex]
Explanation:
From the question we are told that
The distance of the car to north is d = 10 km
The distance of car to the west is w = - 10 \ km
The negative sign is because the direction is west
Generally applying Pythagoras theorem , the displacement is
[tex]H = \sqrt{d^2 + w^2}[/tex]
=> [tex]H = \sqrt{(10)^2 + (-10)^2}[/tex]
=> [tex]H = 14.14 \ km[/tex]

Pete is driving down 7th street. He drives 550 meters in 8 seconds. Assuming he does not
speed up or slow down, what is his speed in meters per second
Answer:
Speed = 68.75m/s
Explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex]
[tex]S = \frac{d}{t}[/tex]
Given the following data;
Distance = 550m
Time = 8secs
Substituting into the above equation;
[tex]S = \frac{550}{8}[/tex]
Speed, S = 68.75m/s
