Answer:
<em>There are 144 cards in 12 packages</em>
Step-by-step explanation:
<u>Direct Proportion</u>
The number of trading cards is directly proportional to the number of packages. We are given there are 84 cards in 7 packages.
Let x= number of packages, y=total number of cards
The direct variation equation is:
y = m.x
Where m is a constant we need to find by using the given data: y=84 when x=7, thus
84 = 7m
Dividing by 7:
m = 84/7=12
The equation is:
y = 12x
For x = 12 packages:
y = 12*12 = 144 cards
The answer is:
There are 144 cards in 12 packages

Answer:
4n + 4
Step-by-step explanation:
Azhar - n years old now.
Last year he was (n-1).
His mother was 4(n -1) last year.
Now his mother 4(n-1) + 1.
7 years later she will be 4(n - 1) + 1 + 7 = 4n - 4 + 8 = 4n + 4
It is given that
A stone is thrown into a pond, A circular ripple spreads over the pond in such a way that the radius is increasing at a rate of 2.5 feet per second.
In one second the increment in radius is 2.5 feet
After t seconds, the increment in radius is given by
The area of the circular ripple is
Substitute r(t)=2.5t, we get
The required function is
Hence the fourth option is correct.
