Answer:
= 1728km2
Step-by-step explanation:
From the formula A = PRT/100%
Where; A is final
P is initial
T is time taken
R is the rate
Therefore A = 3600 × (6/100) × 8
= 1728km2
Answer: the first one would be four then that times 3 would be 12 which is 2 and then 4 times 5 is 20 which would be the third then you could add to check and you would get 36
Step-by-step explanation:
The angle of elevation is 18. 43 degrees
<h3>What is angle of elevation?</h3>
Angle of elevation can be described as an angle formed between a horizontal line and the line of sight above the line.
From the information given, we have that;
- Length of opposite side = 1 meter
- Length of adjacent side = 3 meters
- Angle of elevation = θ
Using the tangent identity, we have;
tan θ = opposite/ adjacent
tan θ = 1/ 3
Divide the values
tan θ =0. 3333
Find the tan inverse of the value to determine θ
θ = tan^-1(0. 3333)
θ = 18. 43 degrees
Hence, the value is 18. 43 degrees

Step-by-step explanation:
First off, what is an integer? An integer is a number that is not a fraction or a whole number but it can be negative or positive.
-5 and -6 are both integers and they are both consecutive integers meaning that they are following one another. So they is no integer between -5 and -6.
