Answer:
8 days
Step-by-step explanation:
90/3 = 30 mi/day
240/30 = 8 days

Answer:
B. 70
Step-by-step explanation:
<h3><u>look at the smaller triangle</u></h3>
its dimensions are : 
45 , 35 , 24
<h3><u>look at the bigger triangle ( this includes the dimensions of the smaller one)</u></h3>
its dimensions are :
45 + 45 ,  x , 24 + 24
= 90 , x  , 48
from the dimensions given we can notice that :
<em>bigger triangle dimensions are  = 2 * smaller triangle dimensions</em>
<em></em>
therefore to find the value of x :
x = 35 * 2
<h3><u>x = 70</u></h3>
<u />
<h3><u>hence the answer is B ) 70 </u></h3>

Answer: Choice H)  2</h3>
=============================================
Explanation:
Recall that the pythagorean trig identity is 
If we were to isolate sine, then,

We don't have to worry about the plus minus because sine is positive when 0 < x < pi/2.
Through similar calculations,  
 
Cosine is also positive in this quadrant.
-------------
So,

Therefore,

is an identity as long as 0 < x < pi/2
 
        
        
        
The general equation of a line is:

When m is the gradient and x1 and y1 are the coordinates of the points on the line
Therefore:
