Step-by-step explanation:

Given that,

Haley hikes 3 miles north and 7 miles east.

We need to find the shortest distance from the campground to the waterfall. Let the distance is D.

It can be calculated as follows :

$D=\sqrt{3^2+7^2}\\D=7.61\ miles$

So, the shortest distance from the campground to the waterfall is 7.61 miles.

Jessica has 48 coins, some of them are nickels and some are dimes. How many of each does she have if she has $3.25 total? 69 POI

Mrrafil [7]

<u>Answer:</u>

Nickels = 44.6

Dimes = 3.4

<u>Step-by-step explanation:</u>

We know that Jessica has 48 coins of which some are nickels and some are dimes so we can write it as:

n = amount of nickels

d = amount of dimes

$n+d=48$ --- (1)

We are to find the number of nickels and dimes if their total worth is $3.25.

Since a dime is worth 10¢ and a nickel is 5¢, so it should be:

$0.05n + 0.3d = 3.25$ --- (2)

From (1):

$n=48-d$

Substituting this value of $n$ in (2) to get:

$0.05(48-d) + 0.3d = 3.25$

$2.4-0.05d+0.3d=3.25$

$2.4+0.25d=3.25$

$0.25d=0.85$

$d=3.4$

Finding $n$ by substituting the value of $d$ :

$n=48-d$

$n=48-3.4$

$n=44.6$

Answer:

1.854826e+134

Step-by-step explanation:

To answer a question like this, you need to know that the factorial of a number is the multiplication of all the posible whole numbers from 0 to the original number. Thus, this problem can be solved calculating 88! (88 factorial) = 88 * 87 * 86 * 85 * 84 * … * 3 * 2 * 1, so the final answer is a very big number, 1.854826 * 10 ^134
