The value of m from the equation is -1/5
<h3>Solving equations and expression</h3>
Given the equation below expressed as;
3(5m + 2) = 3
Expand
3(5m) + 3(2) = 3
15m + 6 = 3
Subtract 6 from both sides
15m + 6 - 6 = 3 - 6
15m = -3
Divide both sides by 15
15m/15 = -3/15
m = -1/5
Hence the value of m from the equation is -1/5

Answer:
P is exactly 3km east from the oil refinery.
Step-by-step explanation:
Let's d be the distance in km from the oil refinery to point P. So the horizontal distance from P to the storage is 3 - d and the vertical distance is 2. Hence the diagonal distance is:

So the cost of laying pipe under water with this distance is

And the cost of laying pipe over land from the refinery to point P is 400000d. Hence the total cost:

We can find the minimum value of this by taking the 1st derivative and set it to 0

We can move the first term over to the right hand side and divide both sides by 400000


From here we can square up both sides






d = 3
So the cost of pipeline is minimum when P is exactly 3km east from the oil refinery.
Answer:
34/55
Step-by-step explanation:
Find the probability of the opposite; not a single vowel chosen.
So, the consonants are 7, so 7/11 times 6/10, which is 21/55.
Then, just 1 - 21/55 to get 34/55

I'm not sure if there is enough information here. If you are asking how many books or bookmarks she can buy, you'll need a total amount of money :).
