Answer: 8,800,000

Step-by-step explanation:

First year recorded number of cars on the roads   = 80, 000,000

Increase rate                                                              = 10%

In the second year , the number of cars recorded  = 10% of 80,000,000

                                                                                    = 10/100 x 80,000,000

                                                                                    = 8,000,000

                                                                                =  80,000,000 + 8,000,000

                                                                                    = 88,000,000

In the third year, the number of cars recorded       = 10% of 88,000,000

                                                                                   = 10/100 x 88,000,000

                                                                                   = 8,800,000

                                                                                  = 88,000,000 + 8,800,000

                                                                                  = 96,800,000.

The number of cars we had  more in the third years compared to year two will be

                                                                                = 96,800,000 - 88,000,000

                                                                                = 8,800,000

Parallelogram L O N M is shown. Diagonals are drawn from point L to point N and from point O to point M and intersect at point Q
Fofino [41]

The length of line segment OM is 34 cm.

<u>Step-by-step explanation</u>:

  • The diagonals of a parallelogram bisect each other (cuts equally into two halves).
  • The line segment OM is a diagonal with an intersection point Q.
  • The line segment OQ is equal in length as the line segment QM.

Step 1 :

⇒ length of OQ = length of QM

⇒ 2x + 3 = 3x -4

⇒ 3x-2x =4+3

⇒ x = 7

Step 2 :

Subsitute x = 7 in OQ and QM

⇒ length of OQ = 2x+3

⇒ 2(7) + 3 = 17 cm

⇒ length of QM = 3x-4

⇒ 3(7) - 4 = 17 cm

∴ Length of OM = length of OQ + length of QM

⇒ OM = 17+17 = 34 cm
