Answer: 18 pages
======================================
Explanation:
Trey reads 10 pages in 25 minutes, which means we have the ratio
10 pages: 25 minutes
Divide each part of the ratio by 25
10 pages: 25 minutes
10/25 pages: 25/25 minutes
0.4 pages: 1 minute
So Trey's unit rate is 0.4 pages per minute. In one minute, Trey reads 0.4 of a page
Now multiply both sides of the last ratio by 45
0.4 pages: 1 minute
45*0.4 pages: 45*1 minute
18 pages: 45 minutes
Which is why the answer is 18 pages
It takes Trey 45 minutes to read 18 pages
Or in other words, Trey reads 18 pages in 45 minutes.
I’m not sure but I need points so please mark this as answer :)
"Combinations" isn't really the right word, because a combination doesn't take order of elements into account, and the outcome of a race certainly does depend on order. "Permutations" would be the correct term.
If 4 students are competing, then the race has
4! = 4 • 3 • 2 • 1 = 24
possible outcomes.
Answer:
C, $4.47
Step-by-step explanation:
Firstly you would see that the cost of 5.2 pounds of grapes is $7.75, so you would divide to find the cost of 1 pound of grapes so 7.75/5.2= 1.49 (round to the nearest 100). Then, times 1.49 by 3. Then you get $4.47
In order to find the value first multiply both sides by 100 to simplify the equation:
0.05w*100=15*100
5w=1500
Next, divide both sides of the equation by 5:
5w/5=1500/5
w=300
The final solution is w=300!
Hope i could help.
have a great day
