I don’t think so because I have never hear of that
<span>Students could also give the answers as green to blue, blue to green, truck , car to truck, blue to total, and green to total.Some students may write part to part ratios. When the class comes back together, this could be a good time to discuss why a part to whole ratio is more useful when comparing statements that include percents. Students may need to be reminded that percents are a form of a part to whole comparison where the whole is 100.hoose different pairs of small groups to post diagrams and explain how the diagram helped them to see the relationship between the fractions, percents, and decimals.</span>
Answer:
-390 mph
Step-by-step explanation:
Let a and b represent, respectively, the distances of A and B from the airport. The distance d between the planes is then given by the Pythagorean theorem as ...
d² = a² + b²
Differentiating with respect to time, we have ...
2d·d' = 2a·a' +2b·b'
Solving for d', we get ...
d' = (a/d)a' +(b/d)b'
The value of d at the time of interest is ...
d = √(a² +b²) = √(30² +40²) = √2500 = 50
Then the rate of change of separation is ...
d' = (30/50)(-250 mph) +(40/50)(-300 mph) = (-150 -240) mph
d' = -390 mph
The distance between planes is decreasing at 390 miles per hour.
25x^2 - 16 = (5x - 4)(5x + 4)
