Set up a proportion:
10 miles - x hours
m miles - 1 hour

$\frac{10}{x}=\frac{m}{1} \\ \\
m=\frac{10}{x}$

The man walks 10/x miles in one hour.

For a package to qualify for a certain postage rate, the sum of its length and girth cannot exceed 85 inches. If the girth is 63

tester [92]

Answer:

Length of package can be = 22 inches

Step-by-step explanation:

Given:

For a package to qualify for a certain postage rate, the sum of its length and girth cannot exceed 85 inches

To find length of package when girth of package is = 63 inches

Solution:

Let length of package be = $l$ inches

Let girth length of package be = $g$ inches

Sum of length and girth of package = $(l+g)$ inches

To qualify for a certain postage rate the sum of length and girth should not exceed 85 inches.

Thus, the inequality representing the situation can be given as:

$l+g\leq 85$

We are given girth of package is = 63 inches

So, inequality to find length would be:

$l+63\leq 85$

Subtracting both sides by 63.

$l+63-63\leq 85-63$

$l\leq 22$ inches

So, length should not exceed 22 inches in order to qualify.

Thus, the maximum length of package to qualify for the postal rate must be = 22 inches

The World Equity Index function shown contains two valuation metrics for the S&P 500. The Verizon description page contains

Nikitich [7]

Answer: Verizon is less expensive than the S&P 500 on both a P/E and dividend yield basis.

Step-by-step explanation:

When a <em>Price to Earnings ratio is relatively high</em> this means that the <em>Price of the security is high </em>because investors believe the company has good prospects.

When a Dividend Yield is relatively low, this means that the dividends being declared are quite lower than the price because Dividend yield is dividends as a percentage of security price. <em>Lower Dividend Yields therefore mean high security prices</em>.

Looking at the Verizon Chart and the S&P 500 you see that Verizon P/E ratio is 11.71 while S&P is 19.01.

This means that the price of Verizon's is less than S&P 500.

Also notice that Verizon's Dividend yield is 4.09% while S&P 500's is 1.91% again signifying that Verizon is cheaper.

I have attached the full question.

There are 3 times elephants compared to giraffes in the safari. If there is a total of 88 elephants and giraffes,how many elepha

77julia77 [94]

There are 66 elephants in the safari.

Solution:
The number 88 refers to both elephants and giraffes that are in the safari. We know that the number of elephants is thrice the number of giraffes. So we can let x be the number of giraffes and 3x be the number of elephants.

We will then come up with the following equation:
3x + x = 88

Then, just add the two variables, and continue the operation.
4x = 88
x = 88/4
x = 22

Now we know that there are 22 giraffes in the safari. So 3x, or 3(22) = 66. There are 66 elephants in the safari.

Select the correct answer.

damaskus [11]

Answer:

None of the above.

Step-by-step explanation:

Let us check each of the answer choices one bye one.

Choice A: $y+41=(31*2)+77x$

solving for y we get:

$y=77x+21,$

which is not equal to our function h(x).

Choice B: $y=317+77x+41$ .

This gives $y=358+77x,$

which is not equal to our function h(x).

Choice C: $x+41=(31*2)+77x$ and $y=31x+77x-41$ .

The first expression does not contain y, thus it is not equivalent to h(x). The second equation already gives the value of y , and we see that it is not equal to h(x).

Therefore we conclude that none of the choices given are correct.
