Maria studied the traffic trends in India. She found that the number of cars on the road increases by 10% each year. If there we
alekssr [168]

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

The measure of an angle is 63.7°. What is the measure of its supplementary angle?
frozen [14]

Answer:

116.3

Step-by-step explanation:

Supplementary angles add to 180

One angle is 63.7, the other is x

63.7+x = 180

Subtract 63.7 from each side

63.7-63.7+x = 180-63.7

x = 116.3

7n^2+16n+15=2n^2+3 solve using Quadratic
Harrizon [31]

Answer:

n=6/5 or n=-2

Step-by-step explanation:

7n^2+16n+15=2n^2+3

collect like terms

7n^2-2n^2 +16n=3-15

5n^2 + 16n= -12

5n^2 +16n + 12

(5n^2+10n)+(6n+12)

5n(n+2)+6(n+2)

(5n+6)(n+2)

n=6/5 or n=-2
