Answer:
4
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 30 = x/8
8 sin 30 =x
8 (1/2) = x

Martin will earn $350 for 28 hours of work.
Step-by-step explanation:
Given, 
Amount earned in 7 hours = $87.50 
Ratio of time to amount earned = 7:87.50
Let, 
x be the amount earned in 28 hours.
Ratio of time to amount earned = 28:x
Using proportion; 
Ratio of time to amount earned :: Ratio of time to amount earned

Product of mean = Product of extreme

Dividing both sides by 7

Martin will earn $350 for 28 hours of work.

Answer:
=22%
Step-by-step explanation:
Since we have given two conditions simultaneously that is windy and not sunny. So we will use the concept of conditional probability.
The probability of sunny day= P(sunny)=10%
P(sunny)=10%=0.1
The probability of windy and not sunny=P(windy|not sun)=20%
P(windy|not sun)=20% = 0.2
Now divide the both probabilities:
P(windy|not sun)/P(sunny)
=0.2/[1-0.1]              
 {Hence there are 10% chances of sun tomorrow than there are (1 - 0.1) chances of no sun}
If we subtract 1 from 0.1 than it becomes:
=0.2/0.9
=2/9
=0.2222222222
=22%
Hence the probability that it is windy = 22% ....
