Marissa collects donations for a dance marathon. One group of sponsors will donate a total of $25 for each hour she dances. Another group of sponsors will make a one-time donation of $100 regardless of how long she dances. What number of hours should she dance if she wishes to raise at least $500?

Answers

Answer:

20 hours

Step-by-step explanation:

25x20=500

The one time donation will not fufill the needs, but the payment each hour will help Marissa reach her donation goal.

One group giving $100 regardless how long but one donating $25 per hour. So $100+25(hours)= 500 to find the solution since they need $500 deduct $100 then it’s 400 divided by 25 which is 16 hours so

$100+25(16)=500 hours. So 16 hours

Answers

Answer: In the diagram, it is a function because the domain(x) is not repeating and so it makes it a function

Step-by-step explanation: This is correct :)

So every triangle has to add up to 180° so for 11 you would have to find out 180-84-36 which would be 60 and because there is a right angle (90°) or the little square you do 90-60 and get 30 then you do 180-86-30 getting you to your final answer of 64
So every triangle ha Sri add 180
