Answer:
1. 110 degrees.
2. 276 students.
Step-by-step explanation:
1. Converting the ratios to fractions:
3 + 4 + 11 = 18 so the largest angle is 11/18 of 180 degrees.
Answer is 180 * 11/ 18 = 110 degrees.
2. That would be 460 * 36 / 60
= 276 students.
Write the times for each hour from start time:
10:25 am
11:25 am
12:25 pm
1:25 pm
2:25 pm
3:25 pm
4:25 pm
5:25 pm
6:25 pm
There are 8 hours between 10:25 am and 6:25 pm.
they finished at 6:15 which is 10 minutes before 6:25 ( 25-15 = 10)
10 minutes less than a full hour is 50 minutes ( 60 - 10 = 50)
8 hours - 1 hour = 7 hours
7 hours + 50 minutes = 7 hours 50 minutes total time.
So we need to first do $75 + $35 = $110 then take $110 * "10% which is 0.1" 'so $110 *0.1 = $11 so $11 is the tax
so now again add $75 + $35 = $110 take $110 + $11 = $121
$121 is her final total
Answer:
A= 9
D=10
Step-by-step explanation:
a=d-1
9=d-1
10=d
Toni can carry up to 5 books
1+2+3b=18
combine 1 and 2
3+3b=18
subtract 3 from both sides
3b=15
divide 3 from both sides
b=5
