Answer:
100000 = 8 (4) ^t
Step-by-step explanation:
We are multiplying by 4 each time
y = a (4)^t
The initial amount is 8
y = 8 (4)^t
We want to get to 100000
100000 = 8 (4) ^t
we can use
volume of cone formula
where
r' is radius of cone
h' is height of cone
we are given
The radius of the cone is half the radius of the cylinder
so,
The height of the cone is equal to the radius of the cylinder
so,
now, we can plug values into formula
we get
we can simplify it
so, option-C.........Answer
Answer:
Tom has 70 cards, and Harry has 28 cards.
Step-by-step explanation:
Let h = number of cards Harry has.
Then the number of cards Tom has is 2 1/2 * h = 2.5h.
Together they have 2.5h + h = 3.5h number of cards.
Together they have 98 cards.
3.5h = 98
h = 98/3.5
h = 28
Harry has 28 cards.
Tom has 2.5h = 2.5 * 28 = 70
Answer: Tom has 70 cards, and Harry has 28 cards.

Just move it to the left 6 times
Answer:
27
Step-by-step explanation:
y=kx
9=k*5, so k=9/5
when x=15
y=(9/5)*15=27
