Use a related multiplication equation to show why the equation 5/n = 0 has no solution

1 answer:

7 0

Multiply both sides by 5:

5/n = 0

then

5/n * n = 0 * n

5 = 0 * n

This cannot be true because there is no number n you can multiply by 0 and get 5.

The vertices of square RSTV have coordinates R(-1,5), S(-3,1), T(-7,3), and V(-5,7). What is the perimeter of RSTV?

Verizon [17]

The distance between two points (x₁,y₁),(x₂,y₂) = √[(x₂-x₁)² + (y₂-y₁)²]

let the length of the square RSTV = d
So, the perimeter of RSTV = 4 d
d is the distance RS or ST or TV or VR

RS distance between R,S
ST distance between S,T
TV distance between T,V
VR distance between V,R

R(-1,5), S(-3,1), T(-7,3), and V(-5,7)

RS = S - R = √[(-3 - -1)² + (1- 5)²] = √[(-2)² +(-4)² ]= √(4+16) = √20 ≈ 4.472

∴ The perimeter of RSTV = 4 d = 4 * 4.472 = 17.888

The attached figure represents an explanation of the problem.
we should note that:
RS = ST = TV = VR = d ≈ 4.472

A small auditorium can seat 320 people which inequality best reprsents the number of people ,p, who can sit in the auditorium

Jet001 [13]

Answer: The answer is $0\leq p\leq 320.$

Step-by-step explanation: Given that in a small auditorium, 320 peoples can sit. The number of peoples who can sit in the auditorium is represented by 'p'.

Since no more that 320 people can sit in the auditorium, so the number of persons who can sit there lies between 0 and 360.

Therefore, the inequalities are

$p\geq 0~~~\textup{and}~~~p\leq 360.$
