Answer:B is the correct option.
Step-by-step explanation:
Looking at the equation representing the first cut,
y = - x/3 + 6
The graph is a straight line graph. The equation for a straight line graph can be represented in the slope intercept form,
y = mx + c
Where
m represents the slope ( change in y / change in x)
c represents the intercept.
Looking at the given equation, the slope is - 1/3
If two lines are parallel, it means that they have equal slope. Since the line of the second cut must be parallel to the line of the first cut, the slope of the line of the second cut will be - 1/3
To find the the intercept of the equation of the line of the second cut, we will substitute
x = - 1/3, y = - 2 and x = 0 into y = - 2 into y = mx + c. It becomes
-2 = - 1/3 × 0 + c
c = - 2
The equation becomes
y = -x/3 - 2
Answer:
So the equation and solution will be:
Total time taken = 3 × number of shirts + 19.87 min (setup time)
= 3 × 143 + 19.87
Step-by-step explanation:
From the question statement, it is clear that
- screen-printing a batch of shirts requires 3 minutes per shirt in addition to 19.87 minutes of initial set-up time.
we have to determine how long does it take to screen-print a batch of 143 shirts.
so the equation and solution will be:
Total time taken = 3 × number of shirts + 19.87 min (setup time)
= 3 × 143 + 19.87
min
Answer:
c
Step-by-step explanation:
a) is wrong.
If A is a subset of B, then cardinality of (AUB) = cardinality B.
For example: A = {1}, B = {1,2,3} cardinality(A) = 1, cardinality(B) = 3.
AUB = {1,2,3} cardinality(AUB) = 3 = cardinality(B)
For the same reason as a), b) is wrong. If B is a subset of A, then the cardinality(AUB) = cardinality(A).
c) is right.
We have already seen that if a set A is a subset of a set B, then cardinality(AUB) = B.
Using A = {1} and B = {2,3}, cardinality(A) = 1, cardinality(B) = 2
Then AUB = {1,2,3} and cardinality(AUB) = 3 = cardinality(A)+cardinality(B)
