The beam of light hit the dolphin at the common point that is the solution of a system:
.
From the second equation express y: y=10-x and substitute it into the first equation:
.
Therefore, the horizontal distance in feet is x=5 ft and the height above water is y=10-5=5 ft.
Answer: the beam of light hit the dolphin at 5 ft above water
Answer: 60
Step-by-step explanation:
Find the total number of students.
In this case, there are 8 total students. Multiply 60 * 8 = 480
Add all the numbers up.
85 + 65 + 36 + 48 + 75 + 39 + 72 = 420
480 - 420 = 60
x = 60

Answer:
The perimeter of the circle is 138.23008
Step-by-step explanation:
The equation to do this is 2πR, the R standing for radius.
The radius of this circle is 22.
For future reference, the radius of any circle is HALF of any line going all the way through the circle, or, like the line below, the whole line.
