3.15 /7 = 0.45
3.20/8 = 0.40
4.10/10 = 0.41
4.80/16 = 0.3
Answer is 1. 7 stamps worth 3.15
Answer:
The worth of car at the start of 2014 = $12000
The value of the car decreased 30% every year.
At start of 2015:
30% of 12000 = \frac{30}{100} \times 12000
100
30
×12000 = 3600
So, the value of the car at start of 2015 = 12000-3600 = $8400.
At start of 2016:
30% of 8400 = \frac{30}{100} \times
8400
100
30
×8400 = 2520
So, the value of the car at start of 2016 = 8400-2520 = $5880.
At start of 2017:
30% of 5880 = \frac{30}{100} \times
5880
100
30
×5880 = 1764
the value of the car at start of 2017 = 5880-1764 = $4116.
So, the value of his car at the start of 2017 is $4116.
Answer:
0.41 cm
Step-by-step explanation:
The scale on the map is 1 in 86 mi.
This means that, 1 cm on the map represents 86 miles in real life, or on earth.
Then we're told that in real life, a distance is 35 miles, and how far they are on the map.
If 1 cm equals 86 miles, then we can say that x cm equals 35 miles
1 cm ----> 86
x cm ----> 35
x * 86 = 35 * 1
x = 35 / 86
x = 0.41 cm
Therefore, they must be 0.41 cm farther or closer apart on the map scale.
