1st: 2x-3 2nd: 2x-1 3rd: 2x+1 4th: 2x+3
adding the above you get 8x=184
Answer:
The original height of the tree is 18 m.
Step-by-step explanation:
Please see attached photo for explanation.
From the diagram, we shall determine the value of 'x'. This can be obtained by using the pythagoras theory as follow:
x² = 5² + 12²
x² = 25 + 144
x² = 169
Take the square root of both side
x = √169
x = 13 m
Finally, we shall determine the original height of the tree. This can be obtained as follow.
From the question given above, the tree was broken from a height of 5 m from the ground which form a right angle triangle with x being the Hypothenus as illustrated in the diagram.
Thus, the original height of the will be the sum of 5 and x i.e
Height = 5 + x
x = 13 m
Height = 5 + 13
Height = 18 m
Therefore, the original height of the tree is 18 m.
Answer:
D.) 10/11
Step-by-step explanation:
Here the given word Probability has 11 letters in it. And we have to calculate the Probability of not selecting a letter P from the above word.
So the formula for calculating any probability is Total Favorable outcomes / Total number of outcomes.
Here total number of outcomes are 11 as word Probability has 11 letters.
So the probability of selecting letter P from word Probability =
Now the P(not P) = 1 - P(selecting letter P)
= 1 - =
You must factoring the number 192, you will get 192=2^6*3, so you have square root(2^6*3)=2^(6/2)*root(3) applying enhancing property.
Solve the exponent and you get =2^3*root(3)= 8*root(3)
