Step-by-step explanation:
5/22 the number you get from the total becomes the numerator and the total amount becomes the denominator
Answer: 6(x)-2/8
Step-by-step explanation:
6 parentheses to represent multiplying,and unknown number inside you would use a variable, and then subtract 2 and use the slash sign ( / ) to represent the fraction bar and write 8 next to it

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.
I would greatly appreciate if you can give this the brainliest answer crown!
Step-by-step explanation:
