Answer:
50
Step-by-step explanation:
d-nr of ducks
g- nr of goats
2*d+4*g=260
d+g=80 /*(-2)
2d+4g=260
-2d-2g=-160
------------------
2g=100
g=100/2
g=50
If the work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb,then the work that is needed to stretch it 18 inches beyond its natural length is 81 ft.lb.
Given that work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb.
We are required to find the work that is needed to stretch 18 inches beyond its natural length.
Multiplication is basically finding out the product of two or more numbers.
Work required to stretch the spring 2 feet beyond its natural length=9 ft. lb.
So, to find the work that is required to stretch the spring 18 feet beyond its natural length, we have to multiply 9 with 9 which will give us 81. So the work required is 81 ft.lb.
Hence if the work required to stretch a spring 2 ft beyond its natural length is 9 ft-lb,then the work that is needed to stretch it 18 inches beyond its natural length is 81 ft.-lb.

Answer:
1244.3 square units
Step-by-step explanation:
The area of a composite figure can be found by decomposing it into its parts, then adding the areas of those parts. This figure can be decomposed into a square of side length 22 units, and two circles, each with radius 11 units.
<h3>Square</h3>
The area of a square is the square of its side length.
A = s²
A = 22² = 484 . . . . square units
<h3>Circles</h3>
The area of a circle is given by the formula ...
A = πr²
A = π(11²) = 121π
The area of the two circles is twice this value, or ...
2A = 2(121π) = 242π ≈ 760.3 . . . . square units
<h3>Total</h3>
The area of the figure is the sum of the areas of its parts:
total area = square area + area of circles
total area = 484 +760.3 = 1244.3 . . . . square units
