Answer:
(√3+1.4)m
Step-by-step explanation:
By forming a right triangle, we can see that the angle of elevation is 30°.
In a 30-60-90 triangle, the side opposite the 30° is the other leg multiplied by 1/√3.
x= 
The height of the pole is (√3+1.4)m

3x*3x=9x^2
3x*-8=-24x
6*3x=18x
6*-8=-48
9x^2-24x+18x-48
9x^2-6x-48
Answer:
8.2
Step-by-step explanation:
We have been given that the ratio of hydrogen to oxygen atoms in water molecules is 2 to 1.
We can represent this information as: 
Let x be amount of moles of hydrogen atoms in water beaker. The proportion of hydrogen and oxygen moles will be same in water beaker.
Upon substituting our values in above proportion we will get,
Therefore, the moles of hydrogen atoms in water beaker will be 8.2.
Answer:
D is the true answer.
Step-by-step explanation:
0.006262 is smaller than 0.062
Answer:
A. 13m
Step-by-step explanation:
To find the area of a square you multiply Length by the Height. Since squares have equal length sides the number has to be the same for the length and the height.
13 x 13 = 169
