Answer:
12ft
Step-by-step explanation:
use sin cos tan method
here, we can see 6ft as adj to the angle and the ladder as hypotenuse
so, adj/hyp = cosθ
--> 6/hyp = cos60
--> hyp = 6/cos60
--> hyp, length of ladder = 12ft
Answer:
A.58
Step-by-step explanation:
120/2=60
60+62=122
180-122=58
It can be deduced that the population proportion formulated shows that the proportion is 3/5.
<h3>How to calculate the population proportion</h3>
Your information is incomplete as the table isn't given. Therefore, an overview will be given. It should be noted that a population proportion simply means a fraction of the population that has a particular characteristic.
In this case, let's assume that the population is 2000 and the most preferred menu item is chosen by 1200 people. Therefore, the <em>population</em> proportion of the most preferred menu item will be:
= 1200/2000
= 3/5.

Answer: Robert ran faster than Jocab
Step-by-step explanation:
Convert the improper fraction to a proper fraction
Jocab = 5miles in 1 1/2 hours, therefore, 1 1/2 hours = 3/2 hours, to convert to minute will be 3/2 x 60 = 90 minutes
Robert = 3 miles in 3/4 hours = 45 minutes
If Robert runs 3 miles in 45 minutes, by the end of 90minutes, Robert would have covered 6miles, while Jocab covered 5miles in 90 minutes, therefore, Robert ran faster than Jocab.
