Answer:
b. 8,800,000.
Step-by-step explanation:
In maria study the number of cars on the road increases by 10% each year.
Total number of cars in the first year =80 million cars.
We will add 10% of 80 million to 80 milion to enable us get the number of cars for the second year.
For year 2 we have;
10% of 80,000,000+80,000,000
8,000,000 + 80,000,000
88,000,000
number of cars in year 2 = 88 million
We will add 10% of 88 million to 88 milion to enable us get the number of cars for the third year.
8,800,000+88,000,000
96,800,000
the number of cars on the road in year 3 compared to year 2 will just be the increase which is in BOLD. That is 8,800,000
<em>or simply subtract the number of cars in year 2 from that in year 3;</em>
96,800,000-88,000,000 = 8,800,000
Answer:
149.30ft
Step-by-step explanation:
Since the vertical distance between the two tower = 40ft
The angle of elevation from the lower tower to te higher tower = 15°
The horizontal distance between the two towers = x
Assuming the angle of elevation and the distance between the two towers makes a right angle triangle, we can use SOHCAHTOA and determine which one would be suitable to find x.
Check attached document for better illustration of the triangle.
Tanθ = opposite / adjacent
Opposite = 40
θ = 15°
Adjacent = x
Tan15 = 40 / x
0.2679 = 40 / x
X = 40 / 0.2679
X = 149.30ft
The horizontal distance between the two towers is 149.30ft
