Answer:
$6981
Step-by-step explanation:
Let's find the answer by using the following formula:
(this year cost)=(last year cost)+((last year cost)*(percent increase of cost)) so:
3750+3650=X+0.06X where X=last year cost, then:
7400=1.06X
6981.13=X
In conclusion, last year he spent $6981.
Based on the given sequence of numbers above, the best definition of it would be a geometric sequence. It is a geometric sequence because term of the sequence of numbers after the first is found by multiplying the previous one by a fixed, non-zero number, and the sequence shows a common ratio.
<span>d = miles from the airport to home.
2.1*d+5=49.10 solve for d
d=</span>49.10-5/2.1 = 21 miles
Answer:
(A) 509.78
We need to move the decimal point after the first non-zero digit
So,
=> 5.0978 × 10² (Since the decimal point is moved two places to the left)
(B) 0.0289
Again after the first non-zero digit:
So, it becomes:
=> 2.89 × 10⁻² (Since the decimal point is moved 2 places to the right so it will be negative also)
