Answer:
Step-by-step explanation:
As per given information there are 18000 CCTV cameras in the area of 783.8 square kilometers
To find the average number of cameras you divide the number by the area.
The average number of CCTV cameras per square kilometer in NYC = 18000/783.8 = 22.9650421026 ≈ 23
It should be rounded up if taking approximate number
Yes you can have as many equal signs as you need and the approximately equal sign in the same equation.
1.) -15.9, -15.2, -3.6, 3.6
2.) second one is already correct
3.)-2.3, -2.03, 2.03, 3.0
Answer:
D = 35.8 degrees
Step-by-step explanation:
In this question, we are asked to use calculator to estimate the approximate measure of angle D given its tan value.
From the question, what we have is;
tan D = 0.72
Now to calculate the acute angle D, we will divide through by tan
hence,
D = tan^-1 0.72
or more simply tan^-1 can be called arc tan
Thus, D = arc tan 0.72
D = 35.75
D = 35.8 to the nearest tenth of a degree
