Answer:
If the length of a tree's shadow is 35.25 meters. The height of the tree to the nearest hundredth of a meter will be : 11.74m
Given:
Denora height=1.35 meters
Length =35.25 meters
Width =31.2 meters
Height of the tree=x
Proportion:
1.35 : 35.25 :: x : 31.2
Now let's determine the height of the tree:
35.25 - 31.2 / 1.35 = 35.25 / x
4.05 / 1.35 = 35.25 / x
Cross multiply
4.05x = 35.25 × 1.35
4.05x = 47.58
Divide both sides
x = 47.58 / 4.05
<u>x = 11.74</u>
In conclusion, if the length of a tree's shadow is 35.25 meters. The height of the tree to the nearest hundredth of a meter will be: 11.74m

Answer: The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.
Step-by-step explanation:
Given: Mean time = 3 minutes
standard deviation = 0.25 minutes
The probability of red lights last between 2.5 and 3.5 minutes :-
The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.
The sales tax rate would be 8%.
To find how much you spent on tax in the total, you'd begin by subtracting the pre-tax notebook from the after tax notebook.
4.86 - 4.50 = 0.36
So now we know that you spent 36 cents on tax. From there, we'd divide our money spent on tax by our pre-tax total.
0.36 ÷ 4.50 = 0.08
This means that the sales tax is 8%.
Hope I could help!
