A container is being filled with water at a steady rate. The graph shows how the volume of water in the container varies with th

Mkey [24]

Answer: a. $v=\dfrac{2}{3}t$ and b. $t=\dfrac{3}{2}v$ .

Step-by-step explanation:

Let as consider,

Volume (in gallons) of water in the container = v

The number of minutes = t

(a)

From the given graph it is clear that the line passing through the points (0,0) and (3,2). So, the equation of line is

$v-v_1=\dfrac{v_2-v_1}{t_2-t_1}(t-t_1)$

$v-0=\dfrac{2-0}{3-0}(t-0)$

$v=\dfrac{2}{3}t$

Therefore, the required formula is $v=\dfrac{2}{3}t$ .

(b)

We have,

$v=\dfrac{2}{3}t$

Multiply both sides by 3/2.

$v\times \dfrac{3}{2}=\dfrac{2}{3}t\times \dfrac{3}{2}$

$\dfrac{3}{2}v=t$

$t=\dfrac{3}{2}v$

Therefore, the required formula is $t=\dfrac{3}{2}v$ .

4.08 rounded to the nearest tenth

madam [21]

Hello!!!!

Rounding becomes really easy if you know your places!
So, if you want to round 4.08 to the nearest tenth, all you would have to do is find the tenth place, in this case, the 8.
Since 8 is above 5, you can automatically round to 10.
So, your answer would be 5!
Hope I helped you!!!!! :)
