elena-14-01-66 [18.8K]

Solution:

The gas can is filled at the rate of 320 cubic inches per minute.

The can is 10 inches long, 8 inches wide, and 12 inches high.

So volume of the can=10 in*8 in *12 in

\text{Volume of can }=960  \ in^3\\

Time required to fill the can=\frac{960}{320}=3  \ minutes\\

Hence Time required to fill the can =3 minutes.

Solve the system of equations using the linear combination method.
Anit [1.1K]
       5p - 3q = -39
-     (-2p - 3q = 3)
==> 7p = -42 ==> p = -6

==> p = -6
      -2(-6) - 3q = 3 ==> 12 - 3q = 3 

==>p = -6
     -3q = 3 - 12 ==> -3q = -9

==> p = -6
       q = 3

Given: LMNP is a square A, B midpoints of LM and PN Q ∈ AB m∠LPQ = 45° Find: m∠PQN
lisov135 [29]
Since A and B are the midpoints of ML and NP, we can say that AB is parallel to MN and LP. In order to find ∠PQN, we can work with the triangles PQB and NQB. According to SAS (Side-Angle-Side) principle, these triangles are congruent. BQ is a common side for these triangles and NB=BP and the angle between those sides is 90°, i.e, ∠NBQ=∠PBQ=90°. After finding that these triangles are equal, we can say that ∠BNQ is 45°. From here, we easily find <span>∠PQN. It is 180 - (</span>∠QNP + ∠NPQ) = 180 - 90 = 90°
