Rounded it equals $30. It was really like $29.83 :)
Answer:
D
Step-by-step explanation:
If he jogged 
miles every day, and he jogged a total distance of 
miles, then he runs for 
days. This is an extension of the 
or distance equals rate times time.
We plug in for y and x to get that he runs for 
.
So, the answer is 
and we're done!
Answer:
13
Step-by-step explanation:
Answer:
volume = 4/3 (pi x r^3)
Volume = 4/3 (pi x 15^3)
Volume = 4/3 (3.14 x 3375)
Volume = 14130 cubic cm

Step-by-step explanation:
the introduction of a fraction tells us that we are dealing with multiplications, and therefore a geometric sequence (where every new term is created by multiplying the previous term by a constant factor, the ratio r).
I think your teacher made a mistake, or you made one when typing the question in here.
there is no factor r that creates
15×r = 9
and
9×r = 5/27
it would mean that
15 × r² = 5/27
r² = 5/27 / 15 = 5/27 × 1/15 = 5/405 = 1/81
r = 1/9
but 15 × 1/9 = 5 × 1/3 = 5/3 is NOT 9
and 9 × 1/9 = 9/9 = 1 is NOT 5/27
so, this can't be right.
on the other hand
15 × r = 9
r = 9/15 = 3/5
and then
9 × 3/5 = 27/5
so, either the sequence should have been
15, 5/3, 5/27
or (and I suspect this to be true)
15, 9, 27/5
under that assumption we have
s1 = 15
r = 3/5
sn = sn-1 × r = s1 × r^(n-1) = 15 × (3/5)^(n-1)
s10 = 15 × (3/5)⁹ = 15 × 19683/1953125 =
= 3 × 19683/390625 = 59049/390625 =
= 0.15116544 ≈ 0.151
