A truck with a heavy load drove from Boston to New York at 50 mph. After dropping of the load, it returned from New York to Bost
leva [86]

Answer:

175/3 or 58.333...

Step-by-step explanation:

This is fairly complicated but I will try to make it as simple as possible. I also apologize in advance for how impossible it is to make fractions look like fractions. I also had to insert a bunch of unnecessary parentheses just because the fractions that I can make are relatively inaccurate.

The distance between 2 cities can be represented as d.

Time is d/r if r is rate, so B->NY=d/50

Similarly,NY->B is d/70

Obviously the average speed is 2d/(d/50+d/70), this is just an average time

Now just remove the d and get (d/d)*2/(1/50+1/70)

You can now multiply by the LCM/LCM, which is 350/350.

After calculating you will get 700/12 which is 58.333...(This is how to enter into your RSM browser) Hope this helps. Sorry it is so late.

Wanahton purified a portion of water with 900 grams of contaminants. Each hour, a third of the contaminants was filtered out.
Ray Of Light [21]

Answer:

B. Geometric sequence.

g(n)=900\cdot (\frac{2}{3})^{n-1}

Step-by-step explanation:

We have been given that Wanahton purified a portion of water with 900 grams of contaminants. Each hour, a third of the contaminants was filtered out.

The amount of contaminants remaining after each hour would be 2/3 of the previous hour amount as 1/3 of contaminants was filtered.

Since amount is not constant, therefore, the sequence would be geometric.

We know that explicit formula for geometric sequence is in form a(n)=a\cdot r^{n-1}, where,

a = First term,

r = Common ratio.

For our given scenario a=900 and r=\frac{2}{3}, so our required formula would be:

g(n)=900\cdot (\frac{2}{3})^{n-1}

Therefore, an explicit formula for the given geometric sequence would be g(n)=900\cdot (\frac{2}{3})^{n-1}.

Libby sold $60 worth of vegetables at the farmer's market. Jess sold 3/4ths of what Libby sold. Stephanie sold 1/3rd of what Jes
Gemiola [76]

Answer:

$120.

Step-by-step explanation:

We have been given that Libby sold $60 worth of vegetables at the farmer's market.

Jess sold 3/4th of what Libby sold. Let us find 3/4 of 60.

\text{Jess sold}=60\times \frac{3}{4}

\text{Jess sold}=15\times 3

\text{Jess sold}=45

Therefore, Jess sold $45 worth of vegetables.

We are told that Stephanie sold 1/3rd of what Jess sold. So let us 1/3rd of 45.

\text{Stephanie sold}=45\times \frac{1}{3}

\text{Stephanie sold}=15

Therefore Stephanie sold $15 worth of vegetables.

Now let us add amounts of money earned by Libby, Jess and Stephanie to get the total money earned by all.

\text{The total money earned by Libby, Jess and Stephanie}=60+45+15

\text{The total money earned by Libby, Jess and Stephanie}=120

Therefore, they all sell $120 worth of vegetables together.

Dan is watching The Birds in his backyard. Of the birds he watches, 9. Of them,or 45%, are sparrows. How many birds are in his b
ra1l [238]

If 9 of the sparrows is 45% of the birds in the backyard, 9/x = 45/100.

Cross multiply to get 9 * 100 = 45x; simplified is 900 = 45x or 20.

This means that there are 20 birds in the backyard. You can check this by dividing 9/20 which equals 45%
