Answer:
A) .
Step-by-step explanation:
We have been given an image of a square pyramid and we are asked to find the volume of our given pyramid.
, where,
a = Base length of square,
h = height of pyramid.
Upon substituting our given values in above formula we will get,
Therefore, the volume of our given square pyramid is 24 cubic meters and option A is the correct choice.
Answer: 81, 243, 729
Step-by-step explanation:
<u>STEP ONE: Find a pattern in the sequence</u>
3 ÷ 1 = 3
9 ÷ 3 = 3
27 ÷ 9 = 3
As we can see from the given sequence, each number multiplies 3 to get the next term.
<u>STEP TWO: Find the next three terms</u>
27 × 3 = 81
81 × 3 = 243
243 × 3 = 729
Hope this helps!! :)
Please let me know if you have any questions
The answer to this question would be: C.5x = 5
In this question, you got two equation which was:<span>1st: 2x + y = 3
2nd: x - 2y = -1</span>
You are asked to multiply one of the equation and add it. If you multiply the first equation, the number of y would be same so the y variable will be removed. If you multiply the second equation, the number of x would be same so the x variable will be removed.
In the answer, all variable that used is x, so the one you need to multiply should be the first equation(removing y with result with x)
<span>4x + 2y = 6
x - 2y = -1
__________+
5x +0y = 5

<u>Answer</u>
<em>The total displacement of the object is 320 m</em>
<u>Solution-</u>
From the formulas of mechanics,
Where,
s = displacement
u = initial velocity = 0 ( ∵ As the body was in rest in the beginning )
t = time taken = 8 s
a = acceleration = -10 m/s² ( ∵ -ve is because of the downward motion)
Putting all the values,
( ∵ -ve displacement means it is in downwards)
