5t/13 = -9
5t = -9 * 13
5t = -117
t = -117/5
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.
To find the answer we can break the figure into two parts: a rectangle and a semi circle.
The perimeter of the rectangle:
(10+4)×2
=28 ft
The perimeter of the semi circle:
perimeter of a circle: 2×兀×radius
(The radius: 4/2)
We divide the perimeter by two as it is a semi circle,which is half the circumferece perimeter of a circle.
[2(3.14)(4/2)] / 2
=6.28 ft
We can then add up the numbers to find the answer, and remember that 4 cm is overlapped:
28+6.28-4
=30.28ft
Therefore the answer is 30.28ft.
Hope it helps!
Answer:
2/2
Step-by-step explanation:
I think so, because 14/2 = 7 and 18/2 = 9
Making the assumption that your problem looks like this,
we use the distributive property to multiply:
