Unusual question. 4/5 = 0.8, which is NOT a repeating decimal; it's a rational fraction.
The numbers that add up to 105 if one is 13 more than the other one is
59 and 46
46 being the smaller number
59 being the number that's 13 more than the first
Answer:
(5, infinitysymbol)
Step-by-step explanation:
First solve the inequality. Subtract 2 from both sides.
x + 2 > 7
x > 5
So that is one way of writing the answer and it is hopefully kind of understandable. X>5 means all the numbers greater (bigger) than 5, forever to infinity.
Interval notation is a way of writing a set or group of numbers. Interval notation uses ( ) parenthesis or [ ] square brackets. Then two numbers go inside with a comma in between. The first number is where the set of numbers start and the second number is where the set ends. You always put parenthesis around the infinity symbol or negative infinity symbol. You only use a square bracket if the inequality symbols have the "or equal to" underline under the > or <.
So x > 5 in interval notation is:
(5, infinitysymbol)
This shows that 5 is not included in the solution; and all the numbers forever bigger than five are solutions as well.
Answer: 13.6% needed more time but then said no. 25.6% were contacted but said no.
To do this problem, you have to create a tree diagram with all of the possibilities.
The first branch separates with 20% not being contacted and 80% being contacted.
Then, the 80% branch can be broken into 12% saying no and 68% needing more time (multiply by 15% and 85%).
Then, the 68% branch can be broken into 54.4% going and 13.6 not going (multiply by 80% and 20%).
With the tree diagram, just pick the percents that you need.
For this case, the first thing you should do is to know the following transformation:
pi radians = 180 degrees
Applying the transformation we have:
(13pi / 6) * (180 / pi) = 390 degrees
Then, in quadrant 1 we have:
390 - 360 = 30 degrees
Answer:
13 pi / 6 as a function of an angle in quadrant i is:
30 degrees
