What is Gravitational acceleration ?Gravitational acceleration can be defined as the acceleration of any object when the object is in free fall. or we can say that the gravitational acceleration is the quantity which describes the acceleration of free falling object within vacuum. It is denoted by g .
What is Potential Energy ?Potential energy is the stored energy of the object which is generally based on the relative position of the various parts of the object. It is also known as gravitational energy.
Formula of potential energy :
PE = mgh
where, PE = gravitational energy / potential energy
m = mass of object
g = gravitational acceleration
h = vertical height of object
According to question given:
PE = 15500J
m = 500kg
g = 9.8
As PE = mgh
therefore, h = PE / mg
i.e. h = 15500 / (500)(9.8)
h = 3.16m

The value of the square root of 64 is -8
Square root integersAn integer is the number zero, a positive natural number or a negative integer with a minus sign. The negative numbers are the additive inverses of the corresponding positive numbers.
The square root of a number is the values that will can multiply twice to give the resulting value in the root.
Given the expression below:
- √64
Since the square root of 64 is 8, hence;
-√64 = -1 * √64
-√64 = -8
Hence the value of the square root of 64 is -8

one morning each member of angela's family drank an 8-ounce mixture of coffee with milk. the amounts of coffee and milk varied from cup to cup, but were never zero. angela drank a quarter of the total amount of milk and a sixth of the total amount of coffee. how many people are in the family?
There are 5 people in the family.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that each member of angela's family drank an 8-ounce mixture of coffee with milk.
Let the number of people would be n.
And a represents the coffee, and b represents the milk,
One-quarter of the milk and one-sixth of the coffee was consumed by Angela.
⇒ Angela drank b/4 of milk and a/6 of coffee.
Since everyone drank the same amount of coffee,
We have been to create an equation as
⇒ (a/6 + b/4)p = a + b
⇒ 2a(6 - n) = 3b(n - 4)
Given that both a and b are positive, we must fulfill the condition.
⇒(6 - n) > 0 and (n - 4) > 0
⇒ 6 > n and n > 4
So, the correct number of people = 5.
Hence, there are 5 people in the family.

One side of the garage was originally 17.7 ft long. (Round to the nearest tenth as needed.) ft long. Question Help One side of the garage is now (Round to the nearest tenth as needed) Enter your answer in the answer box and then click Check Answer. -
Required values:
The length of one side of the garage was originally 17.7 ft long
The length of one of the sides of the garage is now 21.7 ft long
The percentage increase in length is 22.5%.
Given parameters are;
The area of the square garage is 314 ft.²
The area of the new garage has 50% more space
Required;
Initial side length:
The initial side length, given to the nearest tenth, s, is the square root of the area, A, given as follows;
s = √(314 ft.²) ≈ 17.7 ft.
New Side length:
The side was increased by 50%, to give,
314 + 0.5×314 = 471
The new area of the garage = 471 ft.²
The side length of the new garage, s = √(471) ≈ 21.7 ft
The side of the garage now is 21.7 ft.
Percentage increase in length:
The percentage increase is given as follows;
% increase in length
= new side length - old side length / old side length * 100
= 21.7 - 17.7 / 17.7 *100
= 22.5 %

No. of children in lamb, chicken, duck, and turkey category is 66, 24, 18 and 12 respectively.
What is percentage ?Percentage is the value per hundredth.
According to the given question a survey was carried out among 120 school children looked at which type of meat they preferred. 55% said they preferred lamb,20% said they preferred chicken, 15% preferred duck and 10% turkey and we have to calculate no. of children in each category.
55% said they preferred lamb, So the no. of students i this category is
= (55/100)×120
= 66 children.
20% said they preferred chicken, So the no. of children in this category is
= (20/100)×120
= 24 children.
15% said they preferred duck, So the no. of children in this category is
= (15/100)×120
= 18 children.
10% said they preferred turkey, So the no. of children in this category is
= (10/100)×120
= 12 children.

Write an equation in point-slope form
Answer:
y = -4/3x + 2
Step-by-step explanation:
Point slope form is this:
y - y1 = m (x - x1)
Where m is the slope. y1 and x1 are where you put your coordinates.
so now we just plug it in.
y - (-2) = -4/3 (x - 3)
We should clean it up in order to make it look like this equation: y = mx + b
y + 2 = -4/3x -4/3(-3)
y + 2 = -4/3x + 4
y = -4/3x + 2

Step-by-step explanation:
[tex].4\bar{2}[/tex] means the 2 repeats till infinity
[tex].4\bar{2}[/tex] = .4222222222.....
To convert to fraction just take the first three decimal place digits 422 and divide by 1000 to convert to fraction
[tex].4\bar{2} = \frac{422}{1000}[/tex]
Dividing numerator and denominator of this fraction by 2 gives
[tex]\frac{422/2}{1000/2} =\frac{211}{500}[/tex]
This cannot be simplified further and therefore
[tex].4\bar{2} = \frac{211}{500}[/tex]
If we had chosen first 4 decimal digits then it would be[tex].4\bar{2} = \frac{4222}{10000} = \frac{2111}{5000}[/tex]
