zheka24 [161]

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

What is the equation of the following line? Be sure to scroll down first to see
Brut [27]

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 = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 1) ← 2 points on the line

m = \frac{1-0}{-3-0} = - \frac{1}{3}

y = - \frac{1}{3} x ← equation of line

The perimeter of rectangle equals 74 meters. if the length is 5 more than the width, find the width
artcher [175]
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
