Answer:
OPTION C
Step-by-step explanation:
p: 10 > 7 is a true statement.
So, the truth value is T.
q: 10 > 4 is again a true statement.
So, the truth value of this statement again would be T.
So, p and q are true statements.
T & T -----> T.
So, OPTION C is the answer.
Answer:
A: 7
B: 8
C: 6
Step-by-step explanation:
You have to try to find the the same greatest factor of both of the numbers.
Since both of the numbers are divisible by 7 the number of groups equals 7.
So you divide the number of girls, which is 56, by 7, the number of girls in each group is 8.
Then you divide the number of boys, which is 42, by 7, the number of boys in each group is 6.
Here, Original Equation: y = -2x - 5
Compare it with, y = mx + b
So, Slope(m) = -2
Parallel line slope = -2 [ Same ]
Now, y - y1 = m(x - x1)
y - 4 = -2(x + 8)
In short, Your Answer would be Option B
Hope this helps!
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.
