Answer:
tan
Step-by-step explanation:
take 19 degree as reference angle
using tan rule
tan 19=opposite/adjacent
0.34=14/x
x=14/0.34
x=41.17
x=41.2
The answer is 12.3 hours.
On the way to the beach, the family averaged 58 mi/h over 377 mi, so we take 377/58 to find the amount of time spent going to the beach. 377/58 = 6.5 hours.
On the way back, they averaged 65 mi/h over the same 377 mi, so we take 377/65. 377/65 = 5.8 hours.
6.5 + 5.8 = 12.3
Answer:
See below:
Step-by-step explanation:
So, we start off with the equation: 
If we simplify, we can use the distrubutive property to simplify the equation:
Here is how it goes:
So upon simplification of that, we get here: 
Hm, somethings off, do you see that they are the same thing...
So, that means that there would be infinately many solutions.
You can plugin any number and you would get the same result!
If chase won the next 18 matches then he will be able to get a 75% winning record.
Step-by-step explanation:
Let the no. of games chase has to win be 'y'.
He has won 18 matches out of 30.
If he won y matches more he will have a 75% winning record.
To find the percentage we should calculate,
% = (no. Of matches won) x 100/ (total no. of matches)
As the no. of matches won increases, the total no. of matches also increases.
So y should be added to the matches won and also to the total no. of matches played.
[(18+y) /(30+y) ] x 100 = 75%
[(18+y) (100) ] = 75(30+y)
1800 + 100y = 2250 + 75y
100y - 75y = 2250 - 1800
25y = 450
y = 18
So if chase won next 18 matches then he will be able to get a 75% winning record
