Calculate the net force needed to accelerate a 200 kg piano 0.25 m/s^2
Answer:
50 N
Step-by-step explanation:
Net Force= Mass x Acceleration
F=200x0.25
F= 50 N
The net force needed to accelerate a 200 kg piano is 50 Newtons.
What is the force?A force is an effect that can alter an organization’s behavior according to physics. A mass-containing object can change its velocity, or accelerate, as a result of a force. An obvious way to define force is as a thrust or a pull. A vector quantity is called a force since it has both strength and direction.
Force is given as,
F = ma
Where m is the mass of the object, a is the acceleration of the object, and F is the force exerted on the object.
The value of mass is 200 kg and the acceleration of the piano is 0.25 m/s².
Then the force on the piano is given as,
F = 200 x 0.25
F = 50 N
The net force needed to accelerate a 200 kg piano is 50 Newtons.

The graph shows the favorite activities of campers at a summer camp. Suppose there are 300 campers at the camp. How many campers favor fishing?
Answer:
42
Step-by-step explanation:
300 is a multiple of 100. On the graph we can see that 14% of the students favor fishing. 14% of 100 is just 14. Once we have that, we can just multiply by 3, since 3 × 100 = 300:
3 × 14 = 42.
The number of campers supporting fishing will be 42
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the graph shows the favorite activities of campers at a summer camp. Suppose there are 300 campers at the camp. 14% of campers are supporting fishing.
The number of campers supporting fishing will be:-
Number = 300 x 14%
Number = ( 300 x 14 ) / 100
Number = 3 x 14
Number = 42
Therefore, the number of campers supporting fishing will be 42.

dr.loube, a chemist, mixes two solutions. one is 24% acid ( the rest is water) and the other is 41% acid. about how much of each solution does she need to produce 50 gallons of a solution that is 31% acid?
Using a system of equations, the amount of solution a and b required to make the required gallons of the solution are 29.41 and 20.59 respectively.
Let :
Solution with 24% acid = a Solution with 41% acid = ba + b = 50 - - - - (1)
0.24a + 0.41b = 50 × 0.31
0.24a + 0.41b = 15.5 - - - - (2)
From (1) :
a = 50 - b - - - - (3)
Substituting (3) into (2)
0.24(50 - b) + 0.41b = 15.5
12 - 0.24b + 0.41b = 15.5
0.17b = 15.5 - 12
0.17b = 3.5
b = 20.588
From (3) :
a = 50 - 20.588
a = 29.412
Therefore, about 29.41 gallons of solution a and 20.59 gallons of solution b is required.

3/7 of my number is 15 what is my number
Answer:
35
Step-by-step explanation:
It is easiest to find the full number if you find just 1/7 first. We know that we have 3/7 in total, so divide the number, 15, by 3 to get 1/7 of the total number. This gives 5. Therefore, 5 is 1/7 of the total. Thus, to find the total, simply multiply 5 by 7. This gives the total 7/7, 35.

Think of your own reflection in the mirror. It's not exact, like pictures is it? You could also think of it as folding a piece of paper that has wet paint on it in half. The painted image transfers to the other side of the paper, but it's not exactly the same as the original.

On the first day of a family road trip, Kai's family travels 365 miles.
On the third day, they travel 20% farther.
How many miles does Kai's family travel on the third day?
Answer:
438 miles
Step-by-step explanation:
You need to find 120% of 365 because 120% would just be 100% (the starting 365 miles) + the 20% miles on the third day. 120% of 365 would be 438 miles.

IN A CLASS OF 60 STUDENTS, 25 PLAYS BASKETBALL, 2O PLAY VOLLEYBALL, AND 10 STUDENTS PLAY BOTH OF THEM. HOW MANY STUDENTS PLAY NEITHER BASKETBALL NOR VOLLEYBALL?
Answer:
25
Step-by-step explanation:
We'll compare it with the study of sets, the most noticeable operation of which is:
n(A ∪ B) = n(A) + n(B) - n(A ∩ B)where,
n(A ∪ B) is the Union Set, i. e, the set that contains all the elements
n(A) is a subset of the Union Set
n(B) is another subset of the Union Set, and
n(A ∩ B) is the Intersection Set ,i.e, the set contains common elements from both A and B sets.
In the question:n(A ∪ B) = ? (the total number of students in the class who are into the above mentioned sports)Let set A contains the students who play basketball and set B, the students who play Volleyball.
n(A) = 25n(B) = 2010 students play both of them, i. e.,
n(A ∩ B) = 10 (as 10 students have common sports - Volleyball and Basketball)Using the above operation:
=> n(A ∪ B) = n(A) + n(B) - n(A ∩ B)
=> n(A ∪ B) = 25 + 20 - 10
=> n(A ∪ B) = 35
Final Step to the Answer:The total number of students in the class
= students into the given sports + students who don't play any of them
Total number of students in the class is 60Total number fo students playing basketball and volleyball is 35The students who play neither = 60 - 35
= 25
