Answer:
(-5, -4)
Step-by-step explanation:
The formula for a point (x, y) rotating 270 degrees counterclockwise is that it turns into (y, -x). Thus, for (4, -5), its image would be (-5, -4)
Using proportions, it is found that:
a) A raise of $500 would be equivalent to a percentage of 80%.
b) From the above percentage, it would fall into the Gold Award range.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using arithmetic operations such as multiplication and division.
One example of application of proportions is for percentage problems, as a percentage is given by the amount a divided by the total amount b, and multiplied by 100%.
The goal of the raise is of $625, hence b = 625, and considering a raise of $500, a = 500, hence the percentage of the raise is given as follows:
500/625 x 100% = 80%.
To find the range of the raise, we look at the table. For a percentage of 80%, the amount is a Gold Award contribution.

Answer:
81%.
Step-by-step explanation:
To find the average attendance, you will need to find the the total of the average attendance from all 10 days.
Since we know the average attendance of the first 4 meetings was 75%, we can simply assume that those 4 days had this attendance. For this, you can do:
4×75= 300.
Now, for the remaining 6 days, you will need to multiply 85% by the amount of days. 6×85= 510.
Now, to find the average, we will need to add these together:
300+510= 810...
Then divide the result from the total number days to find the AVERAGE:
810÷10= 81%.
