Any number except 0 to the power of 0 is 1.
Thus,
153⁰ = 1
Answer:
Step-by-step explanation:
50 X 4= 200
90 X 5=450
50 X 5=250
200 + 250 = 450
Therefore it takes 5 hours for train B which is the train moving at 90 km per hr to catch up to train A.
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
A. The hexagon as the series is adding a side each time. So you started with 3, 4, 5...
Answer:
x > −3
Step-by-step explanation:
Let's solve your inequality step-by-step.
3(x + 2) > x
Step 1: Simplify both sides of the inequality.
3x + 6 > x
Step 2: Subtract x from both sides.
3x + 6 − x > x − x
2x + 6 > 0
Step 3: Subtract 6 from both sides.
2x + 6 − 6 > 0 − 6
2x > −6
Step 4: Divide both sides by 2.
2x / 2 > −6 / 2
x > −3
Answer:
x > −3
Hope this helps :)
