Write the formula: A=a+b/2(h). Sub in what you know: 9=a+b/2(1). Divide by the height: 1: 9=a+b/2. Multiply by 2: 18=a+b. Now a is typically smaller than b so my guess would be a=6 b=12 but you could pick any numbers as long as they equal 18 :)
Answer:
2
Step-by-step explanation:
Answer:
8,146 x 121
Step-by-step explanation:
This is a problem in which you need to measure your understading of "orders of magnitude."
If the estimated answer is 
that means that we are looking at a multiplication in the "order of" 
You need to look at the "orders of magnitude" of the things you're multiplying. In the first case, we have 
that would be "of the order of" 
times 
. So the whole multiplication would "of the order of" 
or near 
The correct answer, 8,146 x 121, is because it's "of the order of" times 
and the gives us the we need.
Answer:
Option A - ∑Fx and ∑τz and ∑Fy
Step-by-step explanation:
All the force will be in x and y plane only
So Torque will be in z plane
These 3 quantities should be 0
∑Fx and ∑τz and ∑Fy
we have
Step 1
Swap x and y
Step 2
Solve for y
Square root both sides
Step 3
Let
therefore
<u>the answer is the option D</u>
