so, start floor = x
x + 7 - 9 - 4 + 8 - 2 = 14
x = 14
the elevator started on the 14th floor.
to verify: 14 + 7 = 21 - 9 = 12 - 4 = 8 + 8 = 16 - 2 = 14
Answer:
Step-by-step explanation:
A $10,000 deposit at the bank will double in value in 9 years.
If the interest is r% and it is compounded each year, then we can write from the formula of compound interest that
⇒
⇒
⇒ r = 8%
Therefore, the formula for the accumulated amount t years after the investment is made will be
where, P is the invested principal and S is the accumulated sum. (Answer)

Since both sides have the same base (4), we can add the exponents


subtract 5 from both sides:

Answer:
I believe that x is equal to 10
Step-by-step explanation:
bearing in mind that the centroid in a triangle cuts each of the three medians in a 2:1 ratio.
since we know that A C = 12, let's split it in a 2:1 ratio then, cleary from the picture the larger is F C, so F C : A F is on a 2:1 ratio.
