One pound= 16 ounces
2 x 16 = 32 ounces = 2 pounds
2/5 can also be expressed in decimal form as .4
so 32 x .4 = 12.8
and then 3/10 also is .3
so 32 x .3 = 9.6
add the two 12.8 + 9.6 = 22.4
Answer:
A =256 cm^2
Step-by-step explanation:
The perimeter of a square is 64 cm
P = 4s where s is the side length
64 = 4s
Divide by 4
64/4 = 4s/4
16 =s
The side length is 16 cm
The area of a square is
A = s^2
A = 16^2
A =256 cm^2

Answer: 1,953,125
This is one single value and it is just a bit under 2 million.
Or more accurately, it's a bit over 1.9 million.
===========================================================
Explanation:
- a = 5 = first term
- r = -5 = common ratio
Note that dividing any term by its previous term gets us the common ratio
- r = term2/term1 = -25/5 = -5
- r = term3/term2 = 125/(-5) = -5
The r value must stay the same the entire time, or else the sequence isn't geometric.
The nth term of any geometric sequence is a*(r)^(n-1). With the 'a' and 'r' values we found, we update that to 5(-5)^(n-1)
-----------------
To verify that is the correct nth term expression, plug in various values of n to compare it with the given sequence.
If we tried n = 2 for instance, then we find the 2nd term is
5(-5)^(n-1) = 5(-5)^(2-1) = -25
which matches what your teacher gave you. I'll let you verify the other terms.
-----------------
The last thing we need to do is plug in n = 9 and simplify
5(-5)^(n-1)
5(-5)^(9-1)
5(-5)^8
5(390625)
1,953,125 this is one single value (rather than 3 separate values)
