Answer:
2/12
Step-by-step explanation:
Because there are 6 tile total but he wants two put 2 numbers out of the bag twice..... you get the 12 because he pulls a number out twice and since he has 6 and then does it again it adds to 12 so the answer would be 2/12
The rate of change is 2.5.
Answer:
Step-by-step explanation:
The standard compound interest formula is given by:
Where A is the amount afterwards, P is the principal, r is the rate, n is the times compounded per year, and t is the number of years.
Since we are compounding annually, n=1. Therefore:
Lester wants to invest $10,000. So, P=10,000.
He wants to earn $1000 interest. Therefore, our final amount should be 11000. So, A=11000.
And our timeframe is 3.3 years. So, t=3.3. Substituting these values, we get:
Let’s solve for our rate r.
Divide both sides by 10000:
We can raise both sides to 1/3.3. So:
The right side will cancel:
So:
Use a calculator:
So, the annual rate of interest needs to be about 0.03 or 3% in order for Lester to earn his interest.

Answer:
144°
Step-by-step explanation:
The central angle of a sector in a pie chart is proportional to the fraction the represented data is of the whole.
__
<h3>fraction</h3>
The total number of meals ordered at the restaurant was ...
11 +12 +7 = 30
The fraction of those that were Curry was ...
12/30 = 2/5
<h3>angle</h3>
Then the central angle of the sector representing Curry will be 2/5 of the circle, or ...
2/5 × 360° = 144°
The central angle of the section representing Curry will be 144°.
