Sorry no I’m only in 8th :(
We know that 7 cookies at the current price (75 cents less than normal) will cost $2.80.
Thus, we can set up the equation 7(c - .75) = 2.80
Now, let's solve for c.
c - .75 = .4
Add .75 to get:
c = 1.15
Answer:
the height of the building is approximately 134 yards
Step-by-step explanation:
Recall that i order to use the arc-length formula:
we know the radius R, but the angle 
must be given in radians. Then we convert 
to radians, and then use 1700 yards as the radius in the formula.
Therefore, the arc length formula would render:
which rounded to the nearest yard becomes: 134 yards
