Let x be the number of ordinary cars
Let y be the number of SUV's
The difference between the number of ordinary cars and the number of suvs is 17.
So x-y=17 ----> first equation
The number of ordinary cars is larger than the number of sport utility vehicles by 77.3%.
ordinary cars = SUV + 77.3% of SUV
x = y + 0.773y
x = 1.773y
Now we solve for y
We plug in x=1.773y in first equation
1.773y - y=17
0.773y = 17
y = 21.9922
Number of SUV's = 22
Answer:
Option B - 2
Step-by-step explanation:
We have given, the length of a spring when it’s at rest is measured to be 0.56 centimeter.
We have to find, how many significant figures are there in this measurement?
Solution :
The rules to get the significant figure are
- Non-zero digits are always significant.
- Any zeros between two significant digits are significant.
- A final zero or trailing zeros in the decimal portion ONLY are significant.
The given measurement is 0.56 cm.
It has two trailing zeros in the decimal i.e. 5 and 6.
There are only two significant figures.
Therefore, Option B is correct.
Answer:
Elena could tell without finishing by simplifying both sides. The next step would have been 30x +24x = 30x+24. This would have been simplified down to x=1
