Hi there! I can help you! To solve this question, we can write and solve a proportion. Candida ran 100 yards in 12.7 seconds and the timekeeper ran 100 yards in 11.4 seconds. Let's start with Candida. We could solve this by setting up the proportion to make it look like this: 100/12.7 = 220/x. You do this, because we're looking for the amount of time it would take for Candida to run 220 yards. Le'ts cross multiply the values. When you do that, you get 2,794 = 100x. Now, divide each side by 100 to isolate the "x". When you do, you get x = 27.94. x = 27.94. We found Candida's time. Now, let's look for the other person's time. Set up a proportion again. 100/11.4 = 220/x. We are looking for the other person's time. Repeat the steps. Cross multiply the values in order to get 2,508 = 100x. Now, divide each side by 100 to isolate the "x". When you do, you get 25.08. x = 25.08. We found the other person's time. Here are the answers easier to read.
Amount of time to run 220 yards
Candida: 27.94 seconds
Other person's time: 25.08 seconds
Answer:
y = 13x - 55
Step-by-step explanation:
So this is what we know
Selling price = $13 per copy
Expenses = $55
The formula for profit in this case is:
Profit = total selling price - expenses
In which y is the profit
The total selling price is 13x. x here is for the number of manuals she sells
The expenses are $55.
This then becomes y =13x - 55
HOPE THIS HELPED
It is 80 !!!!!!! That’s the number
Answer:
Step-by-step explanation:
2 and 38/45 square yards can be sanded in 3.2 hours.
Step-by-step explanation:
1/2 of an hour is 30 minutes. so 4/9 for every 30 minutes. 1 hour is 8/9. So 3 2/10 would be 3 hours =24/9=2 6/9 and 2/10 would be ( if 5/10 is 30 minutes then 2/10 is 12 minutes.) 8/9 x 1/5 = 8/45. (24 x 5 = 120) 120/45 + 8/45 is 128/45 = 2 38/45
