<span>In this question, the prices are Increased at a monthly rate of 2.3%. Since you are asked how much the percentage in a year and there is 12 month in a year, then you need to do the calculation 12 times.
The calculation would be (100%+2.3%)^12= </span><span>131.37344984%
That would be about 31.37% a year. </span>
Answer:
C
Step-by-step explanation:
According to basic exponential rules, whenever we divide a two same variables, we subtract their powers so would equal
=>
The question is not clear, but I’ll take my best guess:
4+ 85y -12 = 0
85y= 8
y= 8/85 (which you can divide to get a decimal answer)
Answer:
45
Step-by-step explanation:
1/3 of 90
= 1/3 * 90
= 90/3
= 30
Let the missing number be x.
2/3 of x
= 2/3 * x
= 2x/3
30 = 2x/3
Cross multiply,
2x = 30 * 3
2x = 90
x = 90/2
x = 45
Hence,
the missing number is 45.
-10 < n < 8 is the answer
