π=3.14159...
Full circle are 25π cm² = 25*3.14=78.5 cm²
Half 78.5 cm²/2 = 39.25 cm²
A snowflake falls 90 feet in 1 minute.
60 ÷ 4 = 15
6 x 15 = 90
Answer:
y = 2/3x
Step-by-step explanation:
So we know, when lines are perpendicular that they share the same slope. The slope in the equation of y = 2/3x + 7 is 2/3x. So, we have our slope. Now, we just need to find our b. We plug in the point that you gave us into the equation y = mx + b.
3 = 2/3(2) + b
we multiply the denominator 3 by 2, then divide that by the numerator 2.
3 = 3 + b
subtract 3 from itself and from the opposite side of the equal side 3.
0 = b
in the end, there is no b for this equation. Our answer is
y = 2/3x
