blank 2 will be

Statement              Reason

RS≅ST                   Definition of Midpoint

blank 4 will be:

Statement              Reason

RS≅XY                 Transitive Property of Convergence

Step-by-step explanation:

We need to fill the blanks in the table.

In blank 2 we will get:

If S is midpoint of RS, it means it has divided the line segment RS into 2 equal parts. So, blank 2 will be

Statement              Reason

RS≅ST                   Definition of Midpoint

In blank 4 we will get:

We are given:

ST≅XY

and RS≅ST

So, using transitive property of convergence we get

if A≅B and B≅C then A≅C

In our case,

RS≅XY

So, blank 4 will be:

Statement              Reason

RS≅XY                 Transitive Property of Convergence

The men s clothing buyer had a group of 50 jackets priced at $250 each that was selling very slowly. To stimulate sales of these
erastovalidia [21]

Answer:

The answer is $3000.

Step-by-step explanation:

The men's clothing buyer had a group of 50 jackets priced at $250 each.

Total price of jackets = 50\times250=12500 dollars

The buyer reduced the price of the jackets in that group to $200 and 40 jackets were sold.

So, the price for selling 40 jackets is = 40\times200=8000 dollars

Remaining jackets =50-40=10

These were sold at $150 each, totaling to = 10\times150=1500 dollars

So, overall money earned by reducing prices both time = 8000+1500=9500 dollars

And the markdown in dollars = (original price before reducing) minus (educed total price)

= 12500-9500=3000 dollars

So, the answer is $3000.

Last month, a dwarf lemon tree grew half as much as a semi-dwarf lemon tree. A full-size lemon tree grew three times as much as
dimulka [17.4K]

Answer: the dwarf tree grew by 3 inches.

the semi dwarf tree grew by 6 inches.

the full size tree grew by 18 inches.

Step-by-step explanation:

Let x represent how much the semi-dwarf lemon tree grew.

Last month, a dwarf lemon tree grew half as much as a semi-dwarf lemon tree. This means that the amount by which the dwarf lemon tree grew is expressed as x/2

A full-size lemon tree grew three times as much as the semi-dwarf lemon. This means that the amount by which the full-size lemon tree grew is expressed as 3x

Together, the three trees grew 27 inches. This means that

x/2 + x + 3x = 27

Cross multiplying by 2, it becomes

x + 2x + 6x = 54

9x = 54

x = 54/9

x = 6 inches

The dwarf tree grew by 6/2 = 3 inches.

The full-size lemon tree grew by 3 × 6 = 18 inches
