If one inch represents 12 feet what dimension would you use to make a scale drawing of a building 75 feet by 80 feet?
Gemiola [76]
Answer:
6.25 inch by 20/3 inch (6.67 inch).
Explanation:
Use the scale as a conversion factor.
Scale: 1 inch = 12 feet
Conversion factor: by the division property of equaltiy you can divide each side by 12 feet

1 inch / 12 feet = 1
Convert 75 feet:
75 feet × 1 inch / 12 feet = 6.25 inch
Convert 80 feet:
80 feet × 1 inch / 12 feet = 20/3 inch ≈ 6.67 inch
Thus, the dimesions to make a scales drawing of 75 feet by 80 feet are 6.25 inch and 20/3 inch (6.67 inch).

Find the slope that passes through (-7, 1), and (-4, -3)
Andrej [43]

Answer:

The answer is

<h2>-  \frac{4}{3}</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

<h3>m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-7, 1), and (-4, -3)

The slope is

<h3>m =  \frac{ - 3 - 1}{ - 4 + 7}  =  \frac{ - 4}{ 3}  \\ =   -  \frac{4}{3}</h3>

We have the final answer as

<h3>-  \frac{4}{3}</h3>

Hope this helps you

1)) Norachai school is selling tickets for the annual talent show. On the first day of ticket sales, the school sold 5 adult tic
irinina [24]

9514 1404 393

Answer:

  • adult: $5
  • student: $15

Step-by-step explanation:

If we let 'a' represent the price of an adult ticket, and 's' represent the price of a student ticket, the two sales can be described by ...

  5a +4s = 85

  5a +2s = 55

Subtracting the second equation from the first gives ...

  (5a +4s) -(5a +2s) = (85) -(55)

  2s = 30 . . . . simplify

  s = 15 . . . . divide by 2

Substituting this into the second equation, we have ...

  5a +2(15) = 55

  5a = 25 . . . . subtract 30

  a = 5 . . . . . divide by 5

Each adult ticket sold for $5; each student ticket sold for $15.
