Answer:
Step-by-step explanation:
Lets say Rhonda drove x miles, then Jamie drove 2x miles
x+2x=90
3x=90 divide each side by 3
x=30
so Rhonda drove 30 miles and Jamie drove 30*2=60 miles
This is obviously a decreasing sequence. Thus, the common ratio is the fraction 1/4, not the integer 4. Eliminate C and D. Next, at n=1, the value of the 1st term is 16, which is actually 16(1/4)^(1-1) = 16(1) = 16. Thus, B is correct.
Answer:
29 feet above sea level
Step-by-step explanation:
One floor is 9 feet high, so the top of the first floor will be 9 feet above the ground.
The ground is also 20 feet above sea level, so add 9 to this to find how many feet above sea level the top of the first floor is:
20 + 9
= 29 feet above sea level
