It depends on what you're buying. If you're buying food, the state tax of food is 9% of the total. So what you wanna do is multiply 264 times 0.09 and then at that number to your original $264
264*0.09=23.76
264+23.76=287.76
287.76 would be your total. It just depends on what you're buying, what the tax is gonna be. Hope this helped!
So if there are twenty children and 6 have an average age of five, you could say their total age together is 30 years. The others (20-6) have an age of 8.
30+ (20-6)*8 = total age of every child at the library. From there divide by the number of children.
Answer:
10.5cm
Step-by-step explanation:
3+8+7=18, this means that there are 18 parts assuming each part reprecents 1cm
63/18=3.5
so 1 part=3.5cm
3.5*3=10.5cm
Initial tempuratire is at t=0
T(0)=103e^0+73=103(1)+73=103+73=176 degrees
after 90 mins
T(90)=103e^-0.0182*90+72
T(90)=103e^-1.638+73
T(90)=19.6589+73
T(90)=92.6589 degrees
