Answer:
Pat t2 = 40 hrs
Step-by-step explanation:
Given:-
- Fred can paint a house in t1 = 10 hours.
- Pat can paint a house in t2 hours.
- pat and Fred can paint a house in T = 8 hours.
Find:-
Which equation, when solved will produce the number of hours need for pat to paint the house alone
Solution:-
- The number of people working on a particular activity " painting a house " is inversely proportional to time taken to complete the activity. tn = T. The relation for individual time taken ti to complete an activity.
Sum ( 1 / ti ) = 1 / T
Where, ti = The individual time for (ith) person
T = The total time taken to complete the time by i = n number of people.
- For n = 2,
1/t1 + 1/t2 = 1/T
1/10 + 1/t2 = 1/8
1 / t2 = 0.025
t2 = 40 hrs
- It takes Pat t2 = 40 hrs to complete painting the house.
Answer:
115
Step-by-step explanation:
180-65=115
the whole triangle is 180 degrees so subtract 65 degrees from it
This is the graph for y=-2(times)5^x
Hope this helps!
Answer:
y = 0
Step-by-step explanation:
f(x) = (x − 2) / (x − 3)²
Take the limit as x approaches -∞ and ∞. Since the power of the denominator is greater than the power of the numerator, both limits are 0:
lim(x→-∞) f(x) = 0
lim(x→∞) f(x) = 0
So the horizontal asymptote is y = 0.
