Each lion has 1 head. The number of lion heads is L .
Each bird has 1 head. The number of bird heads is B.
The total number of heads of all species is (L + B) = 30
Each lion has 4 feet. The number of lion feet is 4L .
Each bird has 2 feet. The number of bird feet is 2B .
The total number of feet of all species is (4L + 2B) = 100
The system of linear equations is:
L + B = 30
4L + 2B = 100 .
Let's assume
length =l
width =w
we are given
the width of a rectangle is 7 feet less than its length
so, we get
now, we know that
area = length*width
now, we can plug w
we have
Area=170
now, we can factor it
now, we can solve for l
now, we can find width
so, dimensions are
...............Answer
(gof)(3) = g(f(3))
so
f(3) = -2(3) + 8 = 2
g(f(3)) = 5(2) = 10
answer
C. 10
Answer:
Inertia is a tendency to do nothing or to remain unchanged.
It is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line unless that state is changed by an external force.
Answer:
The formula to solve pi to get the area is 3.14r × 2 = Area
3.14 × (radius) × 2 = Area
