Answer:
5 hours and 40 minutes would be class
Step-by-step explanation:
We know that the total time is 7 hours, which in minutes would be:
7 * 60 = 420
420 minutes would be class, now, we subtract the other times that are not to be in class and it would be:
420 - 30 - 50 = 340
So we could say that in class it takes 340 minutes, and if we spend hours it would be:
340/60 = 5.67 hours or also 5 hours and 40 minutes would be class.
Answer: 
Step-by-step explanation:
Given: The number of days Jonathan ran = 5
The most he ran in 1 day = 3.5 miles
Therefore, the maximum distance he ran in a week= 
Let x be the distance Jonathan could have rum in a week, such that
Hence, the required inequality is .
The minimum thickness of the book would simply be the sum
of the thickness of the two cover pages and all the pages in between. That is:
minimum thickness = 0.9 mm * 2 + 0.13 mm * 400
<span>minimum thickness = 53.8 mm</span>
Answer:
40 degrees
100-60=40
Step-by-step explanation:
The angle x is in another angle that looks like 100 and 100 minus 60 is 40.
Hope this helps and if it is correct.
Answer:
x= 2.28
or, x= 0.219
Step-by-step explanation:
2x²-5x+1 =0
a= 2, b= -5 and c= 1
x= (-b <u>+</u> √(b²-4ac))/2a
= (5 <u>+</u> √(25-8))/4
= (5 <u>+</u> √17)/4
