Answer:
$25.17
Step-by-step explanation:
oh boy. mAth and typiNG.
SO, first, find 1% of 21.89 (move the decimal point to the left twice.) That gives us 0.2189.
If she wants to tip 15%, multiply 0.2189 by 15. That means she tips $3.2835. Of course, you round it to $3.28. Because we are finding the total, you add $3.28 to her bill of $21.89. (21.89 + 3.28 = 25.17)
Finally, that means she pays $25.17 in total.
We know that
1 mile----------------> 1609.34 meters
26 miles---------------> X
X=26*1609.34=41842.84 m
I apply a rule of three to know the time
if 100 m---------------9.96 sec
41842.84 m----------> x
x=41842.84*9.96/100=4167.5468 sec
to get minutes I divide it by 60---------> 4167.5468/60=69.459113 minutes
to get hours I divide it by 60----------> 69.459113/60=1.1576518 hours
1.1576518= 1 hour 9 minutes 27.55 sec
the answer is 1 hour 9 minutes 27.55 sec------->(4167.5468 sec)
Step-by-step explanation:
First, you need to find the difference 3201-2750=451, it has increased by 451, then divide the difference by the original number, which is 2750 because thats what she started off with (3201 would be the new number)
Increase% = Increase ÷ Original Number ×100
451÷2750×100=16.4%
Answer:
A. 3(s)
B. 3(150) = 450 and 560 - 450 = 110 remaining books
Step-by-step explanation:
A. The number of leftover books on the shelf depends on the number of students because 3 books are taken per student, and the more students there are, the more books are taken. Specifically in sets of 3, gradually decreasing the total number of books and leaving a smaller amount leftover each time. Using b(s), we would replace "b" with 3 to represent the set of 3 books, since they are multiplied by the amount of students, giving us the formula 3(s).
B. Now that we know how many students are in the school library, in this case 150 is provided, we will also replace "s" with 150, the amount of students that are studying and taking 3 books each. So 3(150) = 450 books, and to find the leftover amount of b, we simply subtract 450 from 560. 560 - 450 = 110, meaning 110 represents the books left on the shelf.
