Answer:
C) 65,535
Step-by-step explanation:
You can add up the 8 terms ...
3, 12, 48, 192, 768, 3072, 12288, 49152
to find their sum is 65535.
_____
<em>Estimating</em>
Knowing the last term (49152) allows you to make the correct choice, since the sum will be more than that and less than double that.
_____
<em>Using the formula</em>
You know the formula for the sum of a geometric sequence is ...
S = a1(r^n -1)/(r -1)
where a1 is the first term (3), r is the common ratio (4), and n is the number of terms (8).
Filling in the values, you find the sum is ...
S = 3(4^8 -1)/(4-1) = 4^8 -1 = 65535
Answer: 77,089.64 or 83,256.81
Step-by-step explanation:
Either or because it doesnt specify is she has to pay 10% and 25% or 10% early and 15% later on. If you know then the lower answer is 10% now and 15% later on. GL!
It’s true
21:35 simplifies to 3:5 when divided by 7 on both sides
24:40 also simplifies to 3:5 when divided by 8 on both sides
Hope that helps!
So, there are two equations.
5a + 3c = 30
a + c = 8, therefore, a = 8 - c
5a + 3c = 30
5(8 - c) + 3c = 30
40 - 5c + 3c = 30
-2c = -10
c = 5 , So a = 3
Answer:
Both are equal
Step-by-step explanation:
Because 4.40 = 4.4
