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:
75
Step-by-step explanation:
i'm going to assume that the base is 10, the formula for a triangle is base x height divided by 1/2 (or 2)
15height x 10base = 150 now divided by 2, 150/2 = 75
B) a pair of parallel planes
C) a pair of straight lines
D) None of these
Answer:
it's A
Step-by-step explanation:
The locus represented by the equation xy+yz=0 is a pair of perpendicular planes
just graph it
Answer: No solution.
Answer 2: (130/51, 157/51)
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)
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.
