If 1 inch represents 12 feet what dimensions would you use to make a scale drawing of 70 feet by 80 feet

The dimensions are 5.83 inches and 6.67 inches

Step-by-step explanation:

* Lets explain how to solve the problem

- The scale drawing is a ratio between the actual length and

  the drawing length

- The terms of the ratio must have the same units, then the terms

  of the scale drawing must have same units

* Lets solve the problem

- 1 inch represents 12 feet

∵ 1 foot = 12 inches

∴ 12 feet = 12 × 12 = 144 inches

∴ The scale drawing is 1 : 144

- That means 1 inch in drawing represents 144 inches in actual

∵ The dimensions are 70 feet by 80 feet

∴ 70 feet = 70 × 12 = 840 inches

∴ 80 feet = 80 × 12 = 960 inches

∵ The scale drawing = 1 : 144

∵ The actual dimensions are 840 inches and 960 inches

∴    1     :     144

     ?     :     840

     ?     :     960

∴ 70 feet = 5.83 inches

∴ 80 feet = 6.67 inches

* The dimensions are 5.83 inches and 6.67 inches

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
