Answer: The answer is 144.
Step-by-step explanation: Let 'a' be the first term and 'd' be the common difference of the given arithmetic progression (A.P.).
According to the given information, A.P. is {0, 4, 8, 12, 16, . . .}, i.e., a=0 and d=4.
The sum of first n terms is given by
So, the sum of first 9 terms is
Thus, the required sum is 144.
Answer:
(a) 60 cups
(b) 5 cookies, 8 muffins and 4 cupcakes in each container
Step-by-step explanation:
Given
Let:
So:
Solving (a): The greatest number of containers to be used;
To do this, we first reduce the ratio to the lowest
C : M : K = 300 : 480 : 240
Divide by 60
<em>The ratio cannot be further reduced. Hence, he will use 60 cups</em>
Solving (b): The number in each cup
In (a), we have:
This means that;
<em /><em> --- Cookies</em>
<em /><em> --- Muffins</em>
<em /><em> -- - Cupcakes</em>
