The sears tower in chicago is 1,450 feet high. a model of the tower is 24 inches tall. what is the ratio of the height of the model to the height of the actual sears tower?

1 : 725

Step-by-step explanation:

Given: The height of the Sears Tower in Chicago = 1,450 feet

We know that 1 feet = 12 inches.

Therefore, the height of the Sears Tower in Chicago in inches =

The height of the model of the tower = 24 inches

Now, the ratio of the height of the model to the height of the actual Sears tower=

Hence, the  ratio of the height of the model to the height of the actual Sears tower = 1 : 725

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.
