Erin should stop at three and a half rounds.
Step-by-step explanation:
One complete round will mow 954 square feet, the total area that she has to mow 3375 square feet. If she goes around three and a half times, she should be finished and stop. This was quite hard to figure out, and may very well be incorrect in some way, but I hope this helps.
Answer:
F(a)=2a^2+4a+5
Step-by-step explanation:
Put "a" where "x" is in the function definition:
F(a)=2a^2+4a+5
6r+7=13+7r
-6r -6r
7=13+r
-13 -13
-6=r
Hope that helps!
Answer:
Step-by-step explanation:
So you first pretend they were all the general admission tickets which is
450x6.50$=2925$ So the number is 4237.50$-2925$=1312.50$ away from the actual price. The price difference between the two is 10.00$-6.50$= 3.50$
Then you put the total price difference 1312.50$ and divide by 3.50$ then you get the amount of upper box tickets. 1312.50$/3.50$=375( Amount of Upper box. So now you know how many upper box were bought. You take it away from 450 tickets sold. 450-375=75
375x10=3750$
75x6.5=487.5$
3750$+487.5$=4237.5$
Hope that helped you!
