Answer: b)
Step-by-step explanation:
You can rule out A) and C), because you have to find area (no adding.)
To do this problem, you can individually multiply the estimated hieght and
width by 3 and then multiply together.
This is because there are 3 walls that each are 9 3/4 tall and 14 1/4 wide. To find total height and width, multiply by 3. Then find total area (lxw)
9 3/4 rounds to 10
14 1/4 rounds to 14
= 3 (10) x 3 (14)
D) is incorrect because you have to multiply each number by 3. (Or you can multiply by 6)
It is B)

Answer:
-312
Step-by-step explanation:
The general term of an arithmetic sequence is ...
an = a1 +d(n -1)
Here, you have first term a1 = 31, and common difference d = 24-31 = -7. So, the 50th term is ...
a50 = 31 -7(50 -1) = 31 -7(49) = -312
The 50th term for the sequence is -312.
Answer:
6.298 meters
Step-by-step explanation:
Here, we are told that x is the time of the dive in minutes.
We simply first need to convert 150 seconds to minutes before substitution into the regression formula;
Kindly recall that 60 seconds = 1 minute
So 150 seconds will be 150/60 = 2.5 minutes
We now proceed to substitute into;
j = 0.010 + 2.515(x)
i = 0.010 + 2.515(2.5)
j = 0.010 + 6.2875
j = 6.2975 which go 3 decimal places is 6.298 meters
