Maylin is mailing a package that has the

yarga [219]

Answer:

V=378 inch³

Step-by-step explanation:

The package is in the shape of a cuboid. The volume of a cuboid is given by :

V = lbh

l=length, b=breadth and h=height

Area of base = 54 inch²

Height of box, h = 7 in

It means that, volume of the package is :

V = 54 × 7

V=378 inch³

So, the volume of the package is 378 inch³.

A= [2, 3; 2, 1], B=[3; 5]. Find AB & BA if possible

oksano4ka [1.4K]

Answer:

The value of AB is $\left[\begin{array}{ccc}21\\11\end{array}\right]$ and it's not possible to multiply BA.

Step-by-step explanation:

Consider the provided matrices.

$A=\left[\begin{array}{ccc}2&3\\2&1\end{array}\right]$ , $B=\left[\begin{array}{ccc}3\\5\end{array}\right]$

Two matrices can be multiplied if and only if first matrix has an order m × n and second matrix has an order n × v.

Multiply AB

Matrix A has order 2 × 2 and matrix B has order 2 × 1. So according to rule we can multiply both the matrix as shown:

$AB=\left[\begin{array}{ccc}2&3\\2&1\end{array}\right] \left[\begin{array}{ccc}3\\5\end{array}\right]$

$AB=\left[\begin{array}{ccc}2\times 3+3\times 5\\2\times 3+1\times 5\end{array}\right]$

$AB=\left[\begin{array}{ccc}6+15\\6+5\end{array}\right]$

$AB=\left[\begin{array}{ccc}21\\11\end{array}\right]$

Hence, the value of AB is $\left[\begin{array}{ccc}21\\11\end{array}\right]$

Now calculate the value of BA as shown:

Multiply BA

Matrix B has order 2 × 1 and matrix A has order 2 × 2. So according to rule we cannot multiply both the matrix.

We can multiply two matrix if first matrix has an order m × n and second matrix has an order n × v.

That means number of column of first matrix should be equal to the number of rows of second matrix.

Hence, it's not possible to multiply BA.

Family traveled 25 miles in 1/2 hour. If it’s currently 3:00 pm and the destination is 225 miles away, what time will they arriv

dangina [55]

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM

Step-by-step explanation:

We have to calculate the speed first to find the time it will take the family to complete the trip.

Given

Distance = d = 25 miles

Time = t = 1/2 hours = 0.5 hours

$Speed =\frac{d}{t}\\=\frac{25}{0.5}\\=50 miles\ per\ hour$

Now,

Distance remaining = 225 miles

Speed = 50 miles per hour

$s=\frac{d}{t}\\t=\frac{d}{s}\\t=\frac{225}{50}\\t=4.5\ hours$

As we see that the time required to complete the journey is 4.5 hours.

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM
