Answer:
7/30
Step-by-step explanation:
-3/9 * -56/80
-3/9= -1/3
-56/80 = -7/10
-1/3(-7/10)
1(7) / 3(10)
7/30 or 0.2333
Answer:
The discount price for a T-shirt cost $14.40.
Step-by-step explanation:
There are more than one ways to solve this problem, I used this method, but your teacher/instructor may uses different method.
First, you will need to find the 1% is, so what I do is to $18 divide 100% (which will split 18 into every single percentage representing). You should get 0.18.
Then, you will multiple 20 from 0.18, that mean you are finding the amount of 20% discount. You should get 3.6.
Now that we found the amount of discount, we need to apply it. We can do that by the orginal price, which is $18, and minus the 20% discount, which is $3.6, (18-3.6=14.4).
$14.4 will be the discounted price for that T-shirt.
I hope that helped!

Answer:
- plane: 530 mi/h
- wind: 40 mi/h
Step-by-step explanation:
Let p and w represent the speeds of the plane and the wind. The relation between time, speed, and distance is ...
speed = distance/time
p +w = (2565 mi)/(4.5 h) = 570 mi/h
p -w = (2205 mi)/(4.5 h) = 490 mi/h
Adding these speeds, we get ...
(p +w) +(p -w) = (570) +(490) mi/h
2p = 1060 mi/h
p = 530 mi/h
Then the speed of the wind is ...
w = 570 mi/h -p = (570 -530) mi/h = 40 mi/h
The plane's speed is 530 mi/h; the wind speed is 40 mi/h.
