Answer:
Around 11:15 am
Step-by-step explanation:
Let h represents the number of hours the plumber works
Since the plumber charges $65 fee plus $75 per hour, the bill can be calculated by:
→ bill = 65 + 75h
Since the bill is $195.25
→ 195.25 = 65 + 75h
→ 75h = 130.25
→ h = 1.74
1.74 implies that the plumber worked almost 1 hour and 45 minutes. Since the plumber started at 9:30, the repair was completed around 11:15 am.
The answer is:
c = 11.40175425
or
c = 11.4
diagram and Pythagorean :
A= 58°B= 83° because you add the straight angle which is 90 plus the other number and subtract it by 180 because a triangle has 180°
Answer:
89.86×10^6
Step-by-step explanation:
9.3×10^7=93,000,000
3.14x10^6=3,140,000
Subtract 93,000,000-3,140,000=
89,860,000
In scientific notation: 89.86×10^6
