sin x= opposite / hypotenuse.
opposite=4
hypotenuse=5
sin x=4/5
x=arc sin (4/5)=53.13º
Answer: x=53.13º
Answer:
OPTION A: 
, where 
.
Step-by-step explanation:
Given: 
Taking 
common outside in the denominator, we get:
will get cancelled on the numerator and denominator, we get:
we know that the denominator can not be zero.
That means, 1 + 8x 
0.
So, the answer is: 
, where 
.
Answer:
a. $3600
b. 6:5
Step-by-step explanation:
Put the question into an equation:
8x - 1/4 x 8x = 5x + 450
(simplify before solving) 6x = 5x + 450
(solve) 6x-5x = 450
x = 450
This means that Jimmy had 8 x 450 $ to start with = 3600
you can check this by subtracting a quarter of 3600 from 3600 and also multiplying 450 by 5 and then obtaining their difference. You get 450!
Now ratio of new amounts:
Jimmy now has: $2700
John still has: $2250
so ratio is 2700:2250
simplify to 6:5
