Answer: 6
Step-by-step explanation:
From the question, we are informed that a factory uses 1/8 of a barrel of raisins in each batch of granola bars and that the factory used 3/4 of a barrel of raisins yesterday.
To calculate the number of batches of granola bars that the factory made yesterday, we divide 3/4 by 1/8. This will be:
= 3/4 ÷ 1/8
= 3/4 × 8/1
= 24/4
= 6
The company made 6 batches of granola bars
Given two vectors

they are parallel if they are a multiple of each other:

You can easily test this by checking if

they are orthogonal if their dot product is null:

For example, in the first case, we have

So, they aren't parallel. Similarly, you have

So, they aren't orthogonal.
In the second case, we have

So, they aren't parallel, and

So, they are orthogonal.
Finally, we have

So, they are parallel (and thus can't be orthogonal)
Answer:
1. x=5
2. x=13
Step-by-step explanation:
1. 1x+2x+2=17
3x+2=17
17-2=15
3x=15
3 X 5 =15
2. -3+x=10
10+3=13
x=13
