Well, scence you don't know how many quarters are in a stack of 5mm, ill give a variable answer...there's 10x as many quarters in the stack of cm than the stack of millimeters, because 5mm=1/2 cm, and 5/.5=10
Answer:
a=3 and b=-2
Step-by-step explanation:
We are given that five terms of a quadratic sequence are
1 8, 21, 40, 65.
The nth term of this sequence
=
We have to find the value of a and b where a and b are integers.
For n=1
......(1)
For n=2
.....(2)
Subtract equation (1) from (2) we get
Using the value of a=3 in equation (1)
Hence, the value of
a=3 and b=-2
Answer:
128 servings
Step-by-step explanation:
5/4 cups of milk for 10 servings is equal to 1/8 cup per 1 serving
there are 16 cups in a gallon
let 'n' = # servings in a gallon
so 1/8 : 1 is 16 : n
1/8n = 16
n = 16(8)
n = 128
I've actually just learned this. We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. And using my calculator the square root of x^2 is just x. And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18.
