Can't see the figure, but the basic way to solve this problem is to use the formula for volume of a pyramid which is (length * width * height )/3. Slant height is just the square root of ((length/2)2 + height2) recognizing that there is a right triangle there. Since slant height increased by 4 cm when its height increased by 2cm, you know that the length/2 term had to increase by the square root of 12 (22+root(12)2) = 42=16. From there you can figure out the rest pretty readily.
Answer:
You only have four terms so n can only be 1, 2, 3 or 4!
I think you mean: What is the nth term of the sequence 15, 12, 9, 6, …?
The ellipsis (…) tells us that the sequence continues.
This is an arithmetic sequence, where the general term is: a+bn
n=1:a+b=15 [Eq. 1]
n=2:a+2b=12 [Eq. 2]
Subtracting Eq. 1 from Eq.2: b=−3
Substituting this into Eq. 1: a−3=15⇒a=18
Thus the nth term is: 18−3n

Answer:
Yes, because it has an end.
Step-by-step explanation:
Rational numbers end, while irrational numbers continue on and there is no visible pattern.
Answer:
$1017.19
Step-by-step explanation:
First find the fraction of how much of Paulo's money is spent on his rent and car. Add 1/4 and 1/8, which is 3/8 because 1/4 = 2/8. Then multiply 3/8 by Paulo's monthly spending, which is $2712.50. Multiplying those numbers will get you $1017.1875. which you have to round up to $1017.19 because you can't spend three quarters of a cent.
