Answer:
The value of m is .
Step-by-step explanation:
If two vectors and
are perpendicular to each other then their dot product will be zero i.e
If two vectors and
are parallel to each other then their cross product will be zero i.e
Given vectors are a= (3,4) and b=(m,2)
The position vector of is =
The position vector of is =
Since and
are perpendicular.
Then,
⇒3.m +4.2=0
⇒3m+8=0
⇒3m= -8
The value of m is .
Answer:
<u>9 parts</u> of beans and <u>12 parts</u> of ground beef is in the chilli.
Step-by-step explanation:
Given:
In a pot of chilli, there are 3 parts of beans to every 4 parts of ground beef.
If a total of 21 combined parts we're used to make.
Now, to find each ingredients is in the chilli.
As, given there are 3 parts of beans to every 4 parts of ground beef.
Let the beans be
And the ground beef be
Total combined parts = 21.
Now, to get the each ingredients we solve an equation:
<em>Dividing both sides by 7 we get:</em>
<em>The beans = </em><em />
<em>The ground beef</em> = .
Therefore, 9 parts of beans and 12 parts of ground beef is in the chilli.
