wolverine [178]

Answer:

10.1%

Step-by-step explanation:

The first thing we should do is calculate the total volume of the solution when mixing them would be:

0.7 + 0.3 = 1

Now, we have that the resulting concentration (x) would be equal to the sum of the multiplications between the volumes and the concentrations to be mixed, as follows:

x * 1 = 0.7 * 0.05 + 0.3 * 0.22

x = 0.035 + 0.066

x = 0.101

That is, the concentration of the resulting mixture would be 10.1% (0.101 * 100)

Describe in words the relationship between the length, width and height of a cuboid and its volume.

Sergio [31]

Volume = length * width * height

Each asterisk * refers to the multiplication symbol

The volume of the cube is equal to the length times width times height

---------------------

Example:

Consider a cube that has length, width and height each equal to 4 cm

Volume = length * width * height

Volume = (4 cm) * (4 cm) * (4 cm)

Volume = (4*4*4) cubic cm

Volume = 64 cubic cm

----------------------

Another example:

We have a rectangular prism that has the following dimensions

length = 4 ft

width = 3 ft

height = 5 ft

Computing the volume gets us:

Volume = length * width * height

Volume = (4 ft) * (3 ft) * (5 ft)

Volume = (4*3*5) cubic ft

Volume = 60 cubic ft

A van and a truck both drove from Town A to Town B. The distance

Gala2k [10]

First we need to find out the time it took for the truck to reach town B.

$Speed= \frac{Distance}{Time}$

$40= \frac{200}{T}$
$T=5hours$

Now, because the van left 1.5 hours earlier and reached the destination 2.5 hours before, it took 1 hour less the the truck to arrive.

$5hours-1hour=4hours$ which is the time it took for the van to arrive.

Now we use the speed equation again to work out speed.

$Speed= \frac{200}{4}$

$Speed=50mph$ = speed of van

Hope this helped :)
