Answer:
Step-by-step explanation:
Given that,
The area of base, A = 24 in²
The height of the pyramid, h = 8 in
We need to find the volume of the following figure.
The volume of pyramid is given by :
Substitute all the values,
So, the volume of the pyramid is equal to .
8! is 40,320
Step-by-step explanation:
- Step 1: Find 8! (8 factorial).
Factorial of 8 is the product of 8 and all the integers below 8.
⇒ 8! = 8×7×6×5×4×3×2×1
= 40,320
Lets call x how wide it is, and write the area equation:
area = width*length
a = (x)(x + 5) = 20000
expand it:
x^2 + 5x = 20000
make a quadratic trinomial:
x^2 + <span>5x - 20000 = 0
</span>lets apply the general quadratic formula to solve:
x = (-5 +- √(25 + 80000))/2
x = (-5 +- 282.89<span>)/2
we take the positive solution:
</span>x = (-5 + 282.89<span>)/2
</span>x = 138.94
therefore the rectangle width is 138.94 m and <span>143.94 m long</span>
Answer:
3/8
Step-by-step explanation:
3/4*1/2
there is 3/4 chance for the first spinner, and a 1/2 chance for the second spinner
Smaller particles moved by the wind occurs through deflation is "True".
<u>Answer:</u> Option A
<u>Explanation:</u>
When the erosion occurs of surface materials or small particles which are loose in nature due to flow of high speed wind current in geological phenomenon than termed as "Deflation" .
These loose material belongs from plain areas of dry, uncemented sediments like which are present in dry lake beds, deserts, floodplains etc.
Deflation differs from wind abrasion because of the effect of particles borne by wind as the method of grinding away a solid object. Deflation reduces the surface of the soil which may produce a blowout which is a depression created by wind erosion on the surface of the land.
