Answer:
A. 176
Step-by-step explanation: First, to find the surface area to each triangle, you multiply the base times the height by 1/2. It is 28 for each triangle. Multiply that by 4, and you get 112. Then, the surface area of the square on bottom is 64. When added together, you get 176. No rounding needed. Hope it helped and is correct!
Answer:
17900
Step-by-step explanation:
First term a = -19
common difference d = -15-(-19) = 4
number of terms, n = 100
sum of first 100 terms,
n/2(2a+(n-1)d)
= 100/2(2×(-19)+(100-1)4)
= 50×(-38+99×4)
= 50×358
= 17900
In order to achieve an equilibrium some of momentum should be zero about the axis of rotation.
Suppose, the 10-kilogram child is placed X meters away from the axis of rotation.
Now, according to the question
17x2+10X-20x2=0
X=0.6m
Child should sit 0.6m away from the axis of rotation towards 17 Kg child.
