Answer:
The initial cost of the cell phone was $364
Step-by-step explanation:
Since there was a 30% markup, 70% of the new cost is the initial cost. Multiply 520 by 0.7 on a calculator and you get 364
I hope this helps you
70=?.25%
70=?.25/100
70=?.1/4
?=280
Answer:
16,17 and 18
Step-by-step explanation:
In statistics mode of a set of entries is the entry which is repeated maximum. There can be more than one mode in a set of entries. These are called mode,
Bimode ( two mode ) , trimode ( three mode ) and Multimode ( four or more ) .
Hence here our set of entries is,
20,17,16,17,18,16,18,19
arranging them in ascending order
16,16,17,17,18,18,19,20
hence in this case we see that 16,17and 18 all are getting repeated for two times, the maximum.
Hence we have a trimode here
16,17,18
You have 3 rows, and 3 columns so
rows x columns=3 x 3
Answer: C
Step-by-step explanation:
We are given the information that:
- The airplane is at 50,000 feet
- It descends 2,500 feet in 1 minute
- x = minutes
For ease of solving this question, let's set the number of minutes (x) to 1.
- In one minute, we know the plane will drop to 47,500 feet. (50,000 - 2,500(x))
There are multiple ways to write this equation bu shifting around negative and positive values. Another way to write this equation would be (-2,500(x) + 50,000). That would be choice C.

It works, so our answer is C.
