The answer would be: He spent 17 hours on the phone
Explanation: $826.20 - $725= $101.2 - $40= $61.12 / $3.60= 17hrs
Answer:
85
Step-by-step explanation:
if the top half is 180° and one side is 95° then the other side is 85°
Answer:
4 : 9
Step-by-step explanation:
Step 1: Find total amount of shapes
16 circles + 20 squares = 36 total shapes
Step 2: Write out ratio of circles to total shapes
16 : 36
Step 3: Simplify by dividing both numbers by 4
16/4 : 36/4
4 : 9
The angle of elevation is 15 degrees. This angle is measured from the horizontal. This problem requires us to review our triangle relationships. This triangle is a right triangle. That means to answer this problem we have to noe the relationship sin(angle) = opposite/hypotenuse. The 3000 is the hypotenuse measurement and we are to find the opposite. 3000sin(15) = 776.45m.
So.. if you notice the picture below.. .the length is that much
thus

take the derivative of A, zero it out, and then check the critica points for any maxima by using the first-derivative test
