Step-by-step explanation:

divide the original prices by 100 them multiply it by 60

motorized train : 9.99 ÷ 100 × 60 = 5.9 ➡$6

doll house : 12.99 ÷ 100 × 60 = 7.794 ➡$7.8

building blocks : 5.69 ÷ 100 × 60 = 3.414 ➡$3.4

In the 1980s land prices in Japan surged upward in a ""speculative bubble."" Land prices then fell for 11 straight years between
Aloiza [94]

Answer:

Step-by-step explanation:

Given the supply of land is perfectly inelastic, the drop in prices must have resulted from decreased demand for land. The demand for land would fall if there were less of a return on the land (i.e., rent), so we can safely assume that land rent fell in Japan between 1990 and 2001. The shifts from D3 to D2 to D1 demonstrate graphically what happened in Japan.

Question 2
prisoha [69]

Answer:

Please check the explanation.

Step-by-step explanation:

<u>Calculating the area of the outer rectangle:</u>

Given

  • The length outer rectangle = l = 3x - 1
  • The width of outer rectangle = w = 5x + 2

Thus,

The area of the outer rectangle:

A = wl

    = (5x + 2) (3x - 1)

    =5x\cdot \:3x+5x\left(-1\right)+2\cdot \:3x+2\left(-1\right)

     =5\cdot \:3xx-5\cdot \:1\cdot \:x+2\cdot \:3x-2\cdot \:1

      =15x^2+x-2

<u>Calculating the area of the inner rectangle:</u>

Given

  • The length inner rectangle = l = x + 7
  • The width of inner rectangle = w = x

Thus,

The area of the outer rectangle:

A = wl

   = x(x+7)

   = x² + 7

<u>Calculating the area of the shaded region:</u>

As

The area of the outer rectangle = 15x² + x - 2

The area of the inner rectangle = x² + 7

  • The area of the shaded region can be determined by subtracting the area of the inner rectangle from the area of the outer rectangle.

Thus,

shaded region Area = Outer Rectangle Area - Inner Rectangle Area

                                  = 15x² + x - 2 - (x² + 7)

                                   =  15x² + x - 2 - x² - 7

                                   = 14x² + x - 9

Therefore, the Area of the shaded region is: 14x² + x - 9

A florist is creating centerpieces for an upcoming event later this evening. She has already been working for two hours and has
Kobotan [32]

Answer:

No inequality given but in my view answer is:

x ≥ 16

Step-by-step explanation:

Given that:

Total time = 6 hours

Remaining Time = 6 - 2 hours = 4 hours (40*6 =240 mins)

Time required for 1 centerpiece = 15 mins

We have to find inequality for x:

Number of centerpieces she makes = x

In 240 mins : 240/15 centerpieces can be made

                    = 16 centerpieces

If she works with the same speed or more efficiently the suitable inequality would be:

x ≥ 16

I hope it will help you!
