Answer:
46.68
Step-by-step explanation:
I don’t know fr but here is a theory.
12ft=50ft shadow
Then,6ft=25ft shadow

3•6=18
Posible answer: 18ft pole:75ft shadow
Answer:
Option C. 2
Step-by-step explanation:
Let
x ----> the number of days
y ----> the internet charges in dollars
we have

This is a proportional relationship between the variables x and y
The slope of the linear function is equal to the constant of proportionality k

The unit rate is the same that the slope
so
The unit rate is $2 per day
therefore
The unit rate in the equation is 2
Answer:
y > -4
Step-by-step explanation:
The hollow circle means that the inequality shows that y is any number strictly greater than 4, not including 4: y > -4
Hope this helps!
