Melissa and brian are at the base of a moutain. Melissa hikes to a location 27 meters above sea.Level brian hikes to a location

AVprozaik [17]

Answer:

Integer that represents Melissa's location with respect to sea level: $27$

Integer that represents Brian's location with respect to sea level: $-21$

Step-by-step explanation:

By definition, Integers can be negative, positive or zero.

Let be zero ( $0$ ) the sea level.

According to the information provided in the exercise, you know that Melissa's location is at 27 meters above the sea level.

Therefore, you can conclude that the integer that represents her location with respect to sea level, is greater than zero (this means that it is positive).

Then, this is:

$27$

Brian's location is 21 meters below sea level.

This indicates that the integer that represents her location with respect to sea level is less than zero (it is negative).

Therefore, this is:

$-21$

suppose we want to choose 6 letters without replacement from 13 distinct letters. A) how many ways can this be done if order doe

kiruha [24]

Answer: A) 1716 B) 1235520

Step-by-step explanation:

If order doesn't matter , then we use combinations, where the number of combinations of selecting r things from n is given by :-

$^nC_r=\dfrac{n!}{r!(n-r)!}$

If order matters , then we use permutations, where the number of permutations of selecting r things from n is given by :-

$^nP_r=\dfrac{n!}{(n-r)!}$

Given, Total distinct letters = 13

To choose = 6 letters

A) Number of ways to choose (if order does not matter)= $^{13}C_6$

$=\dfrac{13!}{6!7!}=\dfrac{13\times12\times11\times10\times9\times8\times7!}{(720)\times 7!}\\\\= $$1716$

B) Number of ways to choose (if order matters)= $^{13}P_6$

$=\dfrac{13!}{7!}=\dfrac{13\times12\times11\times10\times9\times8\times7!} 7!}\\\\= $$1235520$

Hence, A) 1716 B) 1235520

The perimeter of a rectangle is 66 inches.the length is 3 more than twice the width.what are the dimensions of the rectangle?wha

yan [13]

First, set it up as variables

W=x
L=2x+3

apply perimeter formula and solve
2(x+2x+3)=66
2(3x+3)=66
6x+6=66
6x=60
x=10

width=10
length=23
area= 230
