Answer:
There is one solution and that answer is mixed number form 1 5/7 or exact form 12/7
Step-by-step explanation:
57 because 3 times 9 equals 27
Height of the woman = 5 ft
Rate at which the woman is walking = 7.5 ft/sec
Let us assume the length of the shadow = s
Le us assume the <span>distance of the woman's feet from the base of the streetlight = x
</span>Then
s/5 = (s + x)/12
12s = 5s + 5x
7s = 5x
s = (5/7)x
Now let us differentiate with respect to t
ds/dt = (5/7)(dx/dt)
We already know that dx/dt = 7/2 ft/sec
Then
ds/dt = (5/7) * (7/2)
= (5/2)
= 2.5 ft/sec
From the above deduction, it can be easily concluded that the rate at which the tip of her shadow is moving is 2.5 ft/sec.
Answer:
48% were carrot sticks.
52% were apple slices.
Step-by-step explanation:
Given that:
Total number of snacks in the tray = 25
Number of carrot sticks = 12
Number of apple slices = 25 - 12 = 13
Percent of carrot sticks = 
Percent of carrot sticks= 
Percent of carrot sticks = 0.48 * 100 = 48%
Percent of apple slices = 
Percent of apple slices = 52%
Hence,
48% were carrot sticks.
52% were apple slices.
