I cant believe how bad my brother, Reuben, is at growing things. He bought a whole bunch of plants at the nursery the other day.

jeka94

Answer:

68 plants.

Step-by-step explanation:

Let x represent the number of plants that Reuben bought from the nursery.

We have been given that Reuben bought a whole bunch of plants at the nursery the other day. Right away, five died. So number of plant left would be $x-5$ .

We are also told that then our dog dug up 2/9 of them. So number of plants left after dug-up would be $\frac{2}{9}(x-5)$ .

Further a rabbit came and ate ½ of what was left. So number of plants left would be $\frac{\frac{2}{9}(x-5)}{2}=\frac{2}{9\times 2}(x-5)=\frac{1}{9}(x-5)$ .

Since Reuben had only 7 plants left, so we will equate our expression with 7 and solve for x as:

$\frac{1}{9}(x-5)=7$

$9\times \frac{1}{9}(x-5)=7\times 9$

$x-5=63$

$x-5+5=63+5$

$x=68$

Therefore, Reuben bought 68 plants at the nursery.

A baseball player comes up to bat 3 times during a league game. He either gets a hit or gets an out. What is the probability tha

KiRa [710]

Answer:

Since there are 2 possibilities for each bat (hit or out), the amount of total possibilities is 2 * 2 * 2 = 8. There is only one possibility out of those eight that gives us three hits, therefore the probability is 1 / 8 or 0.125.
