Answer:
4 hours
Step-by-step explanation:
The speed of the first car is
While the speed of the second car is
The time it takes for each car to cover a distance d is
where
d = 960 km is the total distance covered
For car 1, the time taken is:
For car 2, the time taken is:
Therefore, the difference in time is:
year 1
cost = 1.03 (1500) = 1545
put 1545 in for x in year 2
year 2
1.03 * 1545 = 1591.35
put in 1591.35 in for x in year 3
year 3
1.03 *1591.35=1639.0905
round to the nearest cent
cost in three years: $1639.09

Answer:
Question 7
Answer : 1200 inches squared
Question: 8
Answer: 84 centimeters squared
Question: 9
Answer: 2304 feet squared
Step-by-step explanation:
1) Q7: Parallelogram
A=BH
base 30 inch X height 40 inch = 1200 inches squared
2) Q8: Rhombus
A=pq
/2
Multiply the two diagonals then divide by 2
Diagonals 14 cent X Diagonal 12 cent divided by 2 = 84 centimeters squared
3) Q9: Trapezoid
A= (B1+B2)H/2
Add the two bases times the height divide by 2
gives you:
2304 feet squared
