There are 42 children in the classroom each student will get 28 pencils and 46 erasers how many pencils will the teacher have to

Aleksandr-060686 [28]

Since the question is asking how many pencils the teacher will have to give out, we can automatically ignore the 46 erasers from the problem because it is not relevant. The information was most likely put there to confuse you.

Each student is getting 28 pencils, so if we multiply the number of students by 28 pencils, we will find how many pencils the teacher will need to give out.

There are 42 children in the classroom, so multiply 42 by 28.

42 * 28 = 1,176

The teacher will have to give out 1,176 pencils to her 42 children in the classroom.

Determine the volume of the parallelopiped determined by the vectors A=<−6,3,2> and B=<−2,10,−5> and C=<1,10,−3&g

Sergio039 [100]

Answer:

The volume of the parallelopiped is 213 cubic units.

Step-by-step explanation:

The given vectors are A=<−6,3,2> and B=<−2,10,−5> and C=<1,10,−3>.

If three vectors $a=,b=,c=$ are given then volume of the parallelopiped is

$V=|a\cdot (b\times c)|$

$a\cdot (b\times c)=\left|\begin{array}{ccc}a_1&a_2&a_3\\b_1&b_2&b_3\\c_1&c_2&c_3\end{array}\right|$

Using the above formula we get

$A\cdot (B\times C)=\left|\begin{array}{ccc}-6&3&2\\-2&10&-5\\1&10&-3\end{array}\right|$

Expand along row 1.

$A\cdot (B\times C)=|-6\cdot \det \begin{pmatrix}10&-5\\ 10&-3\end{pmatrix}-3\cdot \det \begin{pmatrix}-2&-5\\ 1&-3\end{pmatrix}+2\cdot \det \begin{pmatrix}-2&10\\ 1&10\end{pmatrix}|$
