Please let me know if you want me to add an explanation as to why this is the answer/how I got this answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
It is given Nadia goal is to sell 100 tickets out of which she has already sold 17 tickets .
Total number of tickets = 100
Number of tickets sold =17
Number of tickets left = 100-17=83
Nadia can sell 10 tickets in a day
Number of days required to sell remaining 83 tickets if 10 tickets is sold everyday = 83÷10=8.3
Nadia will need minimum of 8+1=9 days to sell the tickets.
Option D 9 is the right answer.
Answer:
C
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 1) ← 2 points on the line
m = 
= - 
y = - x ← equation of line
The perimeter of the rectangle is calculated using the following rule:
perimeter = 2(length + width)
We are given that:
perimeter = 74 meters ............> given I
length is 5 more that width.
This means that:
length = width + 5 ..........> given II
Substitute with given I and given II to get the width of the rectangle as follows:
74 = 2(width+5+width)
74/2 = 2*width + 5
37 = 2*width + 5
37-5 = 2*width
32 = 2*width
width = 32/2 = 16 meters
If you want to get the length, we can use given II as follows:
length = width + 5
length = 16 + 5 = 21 meters
Based on the above calculations:
width of rectangle = 16 meters
length of rectangle = 21 meters
