Answer:Always put the image on top when you are trying to make it into a fraction, and put the pre-image on the bottom. Since the image is 18 we put the it on top and the 8 (pre-image) on the bottom 18. 18/8. Divide it. 18 ÷ 8.

Answer:

Green heart is 2 and blue shape is 8.

Step-by-step explanation:

We know 1 purple drop equals 3.

So 3+3 = 6

The total weight is 16 so we can do 16-6 = 10

We have 10 left. Since we need the weight to be balanced the green heart must be 2.

Because then it would be 8 on 1 side (2 purples equals 6 and 1 heart equals 2, so 6+2=8) and 8 on the other side (8+8=16).

An airplane is flying 600 mph on a horizontal path that will take it directly over an observer. The airplane remains a constant

dezoksy [38]

<h2>Change of the distance between the observer and the airplane when X = 5 miles is 348.84 mph</h2>

Step-by-step explanation:

We have by Pythagoras theorem

Distance between the observer and the airplane² = Horizontal distance² + Altitude²

d² = h² + a²

Here we have

h = X = 5 miles

a = 7 miles

d² = 5² + 7² = 74

d =8.60 miles

$\frac{dh}{dt}=600mph\\\\\frac{da}{dt}=0$

Differentiating d² = h² + a² with respect to time

$2d\frac{dd}{dt}=2h\frac{dh}{dt}+2a\frac{da}{dt}\\\\8.60\frac{dd}{dt}=5\times 600+7\times 0\\\\\frac{dd}{dt}=348.84mph$

Change of the distance between the observer and the airplane when X = 5 miles is 348.84 mph
