Cookies are on sale! Today each cookie costs $0.75 less than the normal price. Right now if you buy 7 of them it will only cost
ivanzaharov [21]
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

6) BRAINLIEST &amp; 10 + POINTS!

Answer:

the height of the building is approximately 134 yards

Step-by-step explanation:

Recall that i order to use the arc-length formula:

arc\,\,length=R\,\theta

we know the radius R, but the angle \theta must be given in radians. Then we convert 4.5^o to radians, and then use 1700 yards as the radius in the formula.

4.5^o*\frac{\pi}{180} =0.07854

Therefore, the arc length formula would render:

arc\,\,length=R\,\theta\\arc\,\,length=1700\,(0.07854)=133.518\, yards

which rounded to the nearest yard becomes: 134 yards
