Suppose the cost for your glass are as follows: •Region 1 (the area between the square and circle A): $0.10 per square inch
•Region 2 (the area between circle A and circle B): $0.15 per square inch
•Sectors for circle B: One sector will be made from expensive glass that is $0.80 per square inch. The rest of the sectors will be from glass that is $0.20 per square inch.

How much does the glass for region 1 cost?
How much does the glass for region 2 cost?
What is the total cost for the glass for the sectors in circle B?
What is the total cost of the glass for your window?
You have only $100 to spend on glass supplies. Do you have enough money to buy your glass?

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:
