The potential energy of the weights is 24500 J.
What is potential energy?Potential energy is the energy an object possesses due to its position.
It depends on its mass, height, and the force of gravity.
Potential energy = mgh
Where g is the acceleration due to gravity and g is 9.8 m/s².
We have,
Potential energy = mgh
where:
m = mass of the weights
g = acceleration due to gravity
h = vertical distance of the weights
Now,
Substituting the values.
Potential energy.
= 1250 x 9.8 x 2
= 24500 J
Thus,
The potential energy of the weights is 24500 J.

You borrow $500. The simple intrest rate is 3%. You pay off the loan after 4 years. How much do you pay for the loan
Given:
Principal value of loan = $500
Rate of simple interest = 3%
Time = 4 year
To find:
The total amount pay for the loan.
Solution:
Formula for simple interest is
[tex]S.I.=\dfrac{P\times r\times t}{100}[/tex]
where, P is principal, r is rate of interest in percent and t is time in years.
[tex]S.I.=\dfrac{500\times 3\times 4}{100}[/tex]
[tex]S.I.=\dfrac{6000}{100}[/tex]
[tex]S.I.=60[/tex]
So, the simple interest is $60.
Now,
[tex]Amount=Principal+S.I.[/tex]
[tex]Amount=500+60[/tex]
[tex]Amount=560[/tex]
Therefore, the total amount pay for the loan is $560.

A scientist graphed the locations of the epicenterof an earthquake and all of the places wherepeople reported feeling the earthquake. Shepositioned the epicenter atmath(−1,8)and thefarthest location reported to have felt thequake was positioned at (85, 8). If each unit onthe graph represents 1 mile, how far from itsepicenter was the earthquake felt?
the earthquake was felt as far as approximately 86 miles away from its epicenter.
How to find what is an earthquake?
The epicenter of the earthquake is located at (-1,8), and the farthest reported location where people felt the earthquake is located at (85,8).
We can calculate the distance between these two points using the distance formula:
d = √((x2 - x1)²2 + (y2 - y1)²2)
where (x1,y1) = (-1,8) is the epicenter and (x2,y2) = (85,8) is the farthest reported location.
Substituting the values into the formula, we get:
d = √((85 - (-1))²2 + (8 - 8)²2)
Simplifying, we get:
d = √((86)²2 + (0)²2)
d = √(7396)
d ≈ 86 miles
Therefore, the earthquake was felt as far as approximately 86 miles away from its epicenter.
An earthquake is a sudden and rapid shaking of the Earth's surface, caused by the movement of tectonic plates beneath the Earth's crust. Earthquakes can vary in size and intensity, from minor tremors to major seismic events that can cause significant damage and loss of life.

Answer:
Area = 95.4 cm²
Step-by-step explanation:
Given
θ = 135°
r = 9cm
Required
Calculate the area of the sector
Area of a sector is:
Area = θ/360 * πr²
Substitute values for θ and r
Area = 135/360 * π * 9²
Area = 0.375 * π * 81
Take π as 3.14
Area = 0.375 * 3.14 * 81

A pole that is 3.4 m tall casts a shadow that is 1.37 m long. At the same time, a nearby tower casts a shadow that is 35.75 mlong. How tall is the tower? Round
your answer to the nearest meter.
Answer:
89 meters tall
Step-by-step explanation:
Create and use the ratio between the shadow and the object given in the problem. If a pole is 3.4 m tall and it's shadow is 1.37 m long. The ratio between the shadow and the object is 340 : 137 in terms of [length of the shadow : length of the object].
Denominator = bottom number of a fraction.
Numerator = top number of a fraction.
To get from one to the other, just convert the ratio into a fraction where the numerator corresponds to what you are converting to. This is because the length of the shadow × length of the object / length of the shadow = length of the object. The denominator cancels.
Just as the length of the object × length of the shadow / length of the object = length of the shadow.
So since 35.75 represents the length of the shadow, you multiply this by 340 / 137 which is 88.7226277372... ≈ 89 meters which is the length of the actual object (to the nearest meter, or whole meter).

find the x and y intercepts. 2x-5y=25
Answer:
hm pic?
Step-by-step explanation:
Answer: X intercepts= ( 25 /2 , 0 )
Y intercepts = (0, -5)
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x . To find the y-intercept, substitute in 0 for x and solve for y .
So to find Y you'll do 2(0)-5y=25
2x0=0........this will make the equation 0-5y=25....0-5y is -5y and 25/-5 is -5. You now know that Y=-5 and X is automattically 0 in these types of problems hence why we plugged in 0 for X to solve for Y.
To find X you'll do the same thing but you'll plug 0 in for Y
so the equation will become 2x-5(0)=25 and 5x0=0 so it will become 2x-0=25 then you'll have to divide to get rid of X. If it does not go in evenly then you leave it as a fraction. This is why you get (25/2, 0)

B. 78
O C. 15.8
O D. 26
E. 52
ОО
F. Cannot be determined
Answer:
A. 19.5
Step-by-step explanation:
Diagonals of a rhombus intersect at right angles. Therefore the angle opposite to AD = 90°.
Thus:
90° + x + 3x + 12 = 180° (sum of ∆)
Add like terms
102 + 4x = 180
Subtract 102 from each side
4x = 180 - 102
4x = 78
Subdue both sides by 4
x = 19.5

(Solve for r) 56 = 7r
Also explain how you got it.
Answer:
r=8
Step-by-step explanation:
56=7r
first I simplified the equation to the form, which is simple to understand
56=7r
Then I move all terms containing r to the left and all other terms to the right.
-7r=-56
Next I simplified the left and right the side of the equation.
-7r=-56
Then i divided both sides of the equation by -07 to get r.
r=8
