Answer:

A= 21.65063509

Step-by-step explanation:

triangle area is =base*hight/2

Because we have a right triangle we can apply the trigonometric functions

sin30 =base/hypothenuse = base/10

cos 30 = hight/hypothenuse =hight/10

sin30 = base /10  ; multiply both sides by 10

base = 10*sin30

cos 30 = hight /10 ; multiply both sides by 10

hight = 10 cos 30

A= 10*sin30*10*cos30/2 =

      100*sin 30*cos 30/2=

            50*sin30*cos30 = ; use calculator make sure is set up in degrees

A= 21.65063509

The price of gas in Bakersville is $2.10 per gallon and is increasing $0.20
Anika [276]

Answer:

5 weeks

Step-by-step explanation:

We are given the following information;

  • Price of gas in Bakersville as $2.10 per gallon

(increment per week is $0.20)

  • Price of gas in Springfield as $2.60 per gallon

(Increment per week as $0.10 )

We are required to determine the number of weeks it will take for the prices to be the same in the two cities.

Assuming it will take n weeks for the prices to be the same, then

New price in Bakersville = $2.10 + $0.20n

New price in Spring field = $2.60 + $0.10n

Thus;

$2.10 + $0.20n = $2.60 + $0.10n

combining the like terms

0.10 n = 0.50

n = 5

   = 5 weeks

Therefore, it will take 5 weeks for the prices to be the same both cities
