A rectangular football field is 64 meters wide and 100 maters long. A player runs from one corner of the field in a diagonal lin

Dimas [21]

Answer:

119 or 118.726577

Step-by-step explanation:

We should use the Pythagorean Theorem to solve this problem.

a^2+ b^2=c^2

64^2+100^2=c^2

4096+10000=14096

c^2=14096

c=\sqrt{14096}14096

And the root of 14096 is 118.726577.

So the Answer is About 119 meters, or 118.726577

hope this helps!

A certain positive integer has exactly 20 positive divisors. What is the smallest number of primes that could divide the integer

Alika [10]

As per my explanation to (b) above, the largest number of primes that could factor such a number is 4.

Note that 2,3,5 and 7 are the smallest primes, then use the reasoning from

(b) above. we are looking for four exponents, that, when 1 is added to each and all are multiplied together, would equal 20.

But no such integers k, l, m, and n exist such that (k + 1)(l + 1)(m + 1) (n + 1) = 20 where k, l,m, and n ≥ 1 so this number, whatever it is, can't have 4 prime factors

Let's drop 7 out of the mix and suppose it has just 3 prime factors 2, 3, and 5 again we are looking for three exponents, that, when 1 is added to each and all are multiplied together, would equal 20. Put another way, we are looking for k, l and m ≥ 1 such that (k + 1)(l + 1)(m + 1) = 20

Note that the only possibility here is when we have 2 *2 *5 = 20 and the smallest possible product would be 2^(4 )* 3^(1) * 5^(1) = 2^4 * 3 * 5 = 240

Now......the only remaining possibility is that this number is composed of the two smallest primes, 2 and 3, and we are looking for some k and l ≥ 1 such that (k + 1)(l + 1) = 20 clearly, the only possibilities are when k = 4 and l = 5, or vice-versa

So this number would factor as either 2^3 * 3^4 = 648 or 2^4 * 3^3 = 432 and both are > 240.

PLEASE HELP ME !!! An apparel company uses a trucking service to deliver products from its warehouse to its retail outlets. For

nexus9112 [7]

Let distance between warehouse and retail outlets be x miles.

We are told that for a one-way trip, the trucking company charges a flat rate of $250 per truck, plus $1.25 for every mile driven. The apparel company has a budget of less than $950 per trip.

Upon multiplying 1.25 by x we will get delivering charges for x miles as 1.25*x. Total delivery charges also include $250 per one-way trip, therefore, 250 will be our constant.

Our total delivery charges for x miles will be,

$1.25\cdot x+250$

The apparel company should service those outlets for whom delivery cost will be less than $950.

$1.25\cdot x+250$

Therefore, an inequality representing apparel company's profit will be $1.25\cdot x+250$ .
