Answer:
100 pieces maybe?
Step-by-step explanation:
Answer:
x = 10√3
Step-by-step explanation:
Because of the right angles, we can use Pythagoras
30² - x² = y² (a) Largest triangle
y² - 20² = h² (b) Medium triangle
substitute y² from (a) into (b)
30² - x² - 20² = h²
500 - x² = h² (d)
x² - h² = (30 - 20)² (c) smallest triangle
substitute h² from (d) into (c)
x² - (500 - x²) = 100
2x² = 600
x² = 300
x = 10√3
Answer:
The table below that is not a function is choice B.
Step-by-step explanation:
All functions have exactly one input for one output, and functions cannot have an input with two different outputs. Since choice B breaks this rule due to the input 2 having outputs 0 and 1, that means that this relationship is not a function.
Use the equation C = 2<span>πr where r is the radius to find the circumference of the track. That is the perimeter around which she has run:
</span>C = 2<span>πr
C = 2</span><span>π(60 meters)
C = 120</span>π meters <span>≈ 377 meters</span>
