Answer:
25 cm^2
Step-by-step explanation:
The side length of square 1 is sqrt(169) = 13
The side length of square 2 is 48/4 = 12
From the Pythagorean Triple 13 - 12 - 5, the side length of square 3 is 5
Finally, 5 * 5 is 25
Answer:
500 pounds
Step-by-step explanation:
Let the pressure applied to the leverage bar be represented by p
Let the distance from the object be represented by d.
The pressure applied to a leverage bar varies inversely as the distance from the object.
Written mathematically, we have:

Introducing the constant of proportionality

If 150 pounds is required for a distance of 10 inches from the object

Therefore, the relationship between p and d is:

When d=3 Inches

The pressure applied when the distance is 3 inches is 500 pounds.
Answer:
137.16
Step-by-step explanation:
we have a formular of the area of a sector:
S= pi*(its angle)/360*R^2
so apply to it
S= pi*(93/360)*13^2=137.16
Remark
Set up the equation from the word problem.
Equation
7*x - x = -48 Combine like terms
6x = - 48 Divide by 6
x = - 48 / 6
x = - 8 <<<<< Answer
