Step-by-step explanation:
area of quadrilateral = sum of area of triangles
area of triangle ADC = .5 * b * h
= .5 * 12 * 5 = 30 km^2
area of ∆ABC = .5 * sinx* ab* ac
= .5 * sin 30 * 3* 13 = 39/4 = 9.75 km^2
area of quadrilateral = 39.75 km^2
total cost =$ 397.5 million
multiply the 2 numbers together than divide by 2
7 1/2 = 15/2
12 2/3 = 38/3
15/2 * 38/3 = 570/6 =95
95/2=47.5 square feet
<span>The unit for potential energy per unit charge, or voltage, is the volt, which has the symbol "V." It takes its name from the Italian physicist Alessandro Volta, credited with inventing one of the first electric batteries.Voltage refers to the work that would be necessary for each unit charge against the existing electric field to move a charge from Point A to Point B. One volt is the equivalent of multiplying one ampere (a unit of current) by one ohm (a unit of resistance). To get the power in terms of watts, it is necessary to multiply the voltage by the current in amps.</span>
Between 2000 and 2030 three decades will have gone by, which means the population will triple three times.

Therefore, the population of Bridgetown will be 675,000 people in 2030.
