You can use the pythagoras’ theorem and just look at one right triangle.
The dimensions for one of the right triangles is (x/2), 8, and square root of 80.
a^2 + b^c = c^2
when c is the square root of 80.
Plug everything in
(x/2)^2 + 8^2 = (square root of 80)^2
That is equivalent to
((x^2)/4) + 64 = 80
Solve for x
((x^2)/4) = 16
Multiple by 4 on each side
x^2 = 64
Take the square root and you have you’re final answer
x = 8
You can determine your speed that is Speed = (distance/Time). Mind you in this cast time should be in hour, so 30 min - 1/2 hour or 0.5 Hour
Your speed is 5/0.5 = 10 mi/hour
Answer:
x > - 7
Step-by-step explanation:
Given
- 3x < 21
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x > - 7
well...
15 x 20 = 300
300+85 = 385
you can get 20 watches for $385
