It's FALSE.
If two lines are parallel they have the same slope!
Answer:
letter C: 100
Step-by-step explanation:
This problem can be configured as an arithmetic progression:
The first value is 10, the ratio is also 10 (the multiples of ten are 20, 30, 40, ...) and the number of terms is 19 (10, 20, 30, ... , 180, 190 -> total of 19 numbers).
So, we can use the following formula to calculate the sum of all these numbers:
Sn = n(a1 + an)
/2
where Sn is the sum, n is the number of terms, a1 is the first term and an is the last one.
The result we want is the average of the sum, so we need to divide Sn by n:
Average = Sn/n = n(a1 + an)
/2n = (a1 + an)
/2 = (10+190)/2 = 200/2 = 100
The correct option is letter C.

Answer:
Rs 8.90
Step-by-step explanation:
Given;
Cost per metre C = Rs 15.25
Length of cloth l = 7/12 m
The cost of a particular amount of cloth can be derived by multiplying the cost of cloth per metre by the length in metres of the cloth.
Cost = cost per metre × length
Substituting the given values;
Cost = Rs 15.25 per metre × 7/12 metre
Cost = Rs 8.90
the cost of 7/12 m of cloth at Rs. 15 25 per metre is
Rs 8.90
