Answer:
Maria's homework time is now 9 hours 12 minutes.
Step-by-step explanation:
Since Maria decides to increase her homework time by 15%.
Then,
15% of 8 hours = 
x 8 hours
= 0.15 x 8 hours
= 1.2 hours
(Note that: 1.2 hours = 1 hour 12 minutes)
15% of 8 hours = 1 hour 12 minutes
her new homework time = 8 hours + 1 hour 12 minutes
= 9 hours 12 minutes
Maria's homework time is now 9 hours 12 minutes.
Answer:
slope is 0
y-(-8)=0(x-(-2))
y+8=0(x+2) no solution
Step-by-step explanation:
b= 14 because the formula to find a triangles area is 0.5bh. So, you take 147 and divide it by 21 then multiply the answer of that (which is 7) by 2 because the reciprocal of 0.5 is 2.
Answer:
725.7
Step-by-step explanation:
