Answer: a) 15 b)
Step-by-step explanation:
Let X be the number of days:
a)
For LESSONS:
Jordan does 10 / day ( 10*X)
Marco 5 / day ( 5*X)
Junyi 5 / day ( 5*X)
For TESTS:
Jordan does 5 / day ( 5*X)
Marco 10 / day ( 10*X)
Junyi 8 / day ( 8*X)
for each they need a total of 300
a) 
days for the lessons
b) 
days for the tests
so they need 15 days to finish both tasks
now if Junyi gets sick we just eliminate his contribution
a) 
days for the lessons
b) 
days for the tests
so in 20 days they will finish without him
If jordan works 10 hours a day, we just replace him with 10/24
a) 
days for the lessons
b) 
days for the tests
so at the end to complete both tasks they need 29.58 days
Answer: Area of cross section that is parallel to face CDHG is 432 cm².
Step-by-step explanation:
Since we have given that
There is a cross section that is parallel to face CDHG.
So, Length of cross section would be 36 cm
Width of cross section would be 12 cm.
So, Area of cross section would be
Hence, Area of cross section that is parallel to face CDHG is 432 cm².
Answer:
q=-5
Step-by-step explanation:
6+q=1

q=1-6
q=-5
Quadrant I
405=360+45 405-360=45
