Answer: $43.75
Step-by-step explanation: Okay u need to multiply these up first 5 x 8.75= 43.75
so that is how much she will need to get each costumes.
Now this is the answer because if there are 5 costumes and they are 8.75 yards of fabric if u have to find how much of red for 5 costumes u just multiply the costumes by how much fabric there is. If there is 5 costumes its gonna come out to be as much as she had to spend on 5 costumes if that makes any scene to you :)
Hope this helped u :)
good luck!!

Alright, so the distance formula is sqrt((x1-x2)^2+(y1-y2)^2), and plugging that in, we get sqrt((0-3)^2+(3-10)^2)=sqrt((-3)^2+(-7)^2)=sqrt(9+49)=sqrt(58)=around 7.6
Answer:
12/27
Step-by-step explanation:
You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Let the total number of marbles = 6 red marble + 3 blue marbles = 9 marbles
You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Assume all you picked is red( without replacement)
= 6/9 × 5/9
= 30/81
= 10/27
Assume all you picked is blue( without replacement)
= 3/9 × 2/9
= 6/81
= 2/27
The probability of the events is calculated as:
All red or All blue
= 10/27 + 2/27
= 12/27

It's best to subtract 4 first
Answer: 44%
Step-by-step explanation:
There are other ways of doing this but here's how I did it:
Starting with an arbitrary price for the shirt of $100, I took 30% off and arrived at $70.
Then 20% off $70 is $56 (20% is one-fifth, so divide 70 by 5 and you get 14. Subtract 14 from 70 and you get 56.
Now subtract 56 from 100 and you get 44, so to get to 56 from 100 you subtract 44%.
You could also use a calculator or google it but that would be missing the point of studying math and benefiting from its practical applications, e.g., how to figure things out for yourself. And that wouldn't be much fun, would it?
