7 1/4 + 5 3/5 = 12 17/20 You can't reduce it no more.
Answer:
B
Step-by-step explanation:
if y = -3 then 4+(-3)/4(-3) would be 4-3 = -1 over -12 so -1/-12 or 1/12 -->B
Answer:
- Two unique triangles possible
Step-by-step explanation:
Given two sides of 10 cm and one 40° angle
<u>If we use these, we'll get isosceles triangle with:</u>
1. Included 40° angle.
<u>Then the other angles will be same and measure:</u>
2. Adjacent 40° angle. Then one of the angles must be 40° angle as opposite of 10 cm sides.
<u>The remaining angle will measure:</u>
There no more unique triangles possible, so the answer is two.
This is simple division:

So, plug it into your calculator and you get:

Your answer's that
it takes 4.5 hrs for the surveillance run.
