Which equation will solve the following word problem? One small pitcher and one large pitcher can hold 12 cups of water. If the

Inessa [10]

Answer:

Option (1).

Step-by-step explanation:

Amount of water hold by both the pitchers (Large + small) = 12 cups

Let the small pitcher holds the water = S cups

If the water hold by the large pitcher is twice the size of the small pitcher, then the amount of water hold by large pitcher = 2S

Total amount water hold by both = S + 2S

Equation for this situation will be,

S + 2S = 12

Therefore, Option (1) will be the answer.

Answer:

360 or 38

Step-by-step explanation:

Number 1 :

2 * 2 * 5 * 6 * 3

4 * 30 * 3

120 * 3 = 360

Number 2 :

5 + 3 + 2 = 10

10 × 2 = 20

6 * 3 = 18

20 + 18 = 38

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across

nasty-shy [4]

Answer:

Domain is $[0,18]$

Average rate of change of bacteria per minute is -3333.33.

Step-by-step explanation:

Domain is the possible values of $x$ .

From the graph, it's clear that the $x$ values ranges from 0 to 18 as the end points of the graph are $(0,60)$ and $(18,0)$

So, domain of the function is $[0,18]$ .

Now, average rate of change is negative as there is bacteria decay.

Average rate of change is given as the negative ratio of y intercept to the x intercept.

Here, x-intercept is 18 and y-intercept is 60000.

So, average rate of change is given as,

$R_{avg}=-\frac{60000}{18}=-3333.33$

Therefore, average rate of change of bacteria per minute is -3333.33.
