You are going to the movie theater with your parents and your 8 year-old brother. Adult tickets cost $8, ages 10 -18 cost $7.25 and under age 10 cost $4.25. If you spent an additional $20 on soda and popcorn, what is the total cost of your trip to the movie theater
Answers
Answer:
The answer is $47.50
Step-by-step explanation:
All you have to do is add up the price of each person attending with what age price for each and then add the additional $20 for the sodas and popcorn.
Two parents = 8.00 + 8.00 = $16.00
"You" would most likely be student price, so.. = $7.25
And 8 year-old little brother is under 10, so.. = $4.25
Adding up those three prices we get $27.50, now all to do is add the additional drinks and snacks price. 27.50 + 20.00 = $47.50

Answer:
a) 121
b) 425
Step-by-step explanation:
We are given the following information in the question:
198 + 727 + 200 + 725 = 925
This can be explained with the help of associative of addition and subtraction and commutative property of the addition.
Associative property:
Commutative property:
a)
b)
200 is easier to add with because there are zeroes in the tens place and the ones place.
725 is easier to add with than 727 because the ones place digit, (5), is an easier base to use, just like zero.
Using the easier numbers, 200 + 725 = 925
Using the original numbers, 198 + 727 + 925
*Because you took two pieces from the 727 and added them to 198, the four numbers in this problem are compatible.
Compatible numbers are when you use numbers that are close to the original ones and make it easier to do the problem in your head.

In the case of 87+ 34, the simplest numbers to use would be 90 instead of 87 and 35 instead of 34. Not as easy as the first equation, but still doable.
90+35+125
or
87+34=121
____
In the case of 222+203, the simplest substitutions are 220 and 200.
220+200=420
or
222+203=425

Answer:
the surface area will increase 16 feet per minute
Step-by-step explanation:
Allow me to revise your question for a better understanding.
A spherical balloon is inflating with helium at a rate of 64π Start Fraction ft cubed Over min End Fraction ft3 min. How fast is the balloon's radius increasing at the instant the radius is 2 ft? How fast is the surface area increasing?
My answer:
Given that:
(1)
As we know that, the volume of a spherical balloon can be calculated by using the following formula:
where r is the radius
Substitute V into (1), we have:
In this situation, the instant radius is: 2f
So we have:
The radius of the balloon is increasing at a rate of 4 feet per minute
The the surface area has the formula as:
SA1 = 4π
If the radius of the balloon is increasing at a rate of 4 feet per minute, so the
the surface area will increase 16 feet per minute because:
SA2 : 4π = 16 (4π
) = 16 SA1
Hope it will find you well.
