Answer:
7.8 × 10^-4
Step-by-step explanation:
Although this answer is perfectly O.K., most commonly the base, or the 0.00078, is written as a number with just one digit to the left of the decimal.
To format your number in this way, we'll multiply the .00078 by 10, 4 time(s), making it a 7.8.
We do this, because each multiplication by 10 moves the decimal point to the right one digit.
But in order to keep our number the same number, we must have a × 10-4 next to the 7.8.
So, the final answer is 7.8 × 10^-4
50 + .35x = 75 + .25x
.1x = 25
25 divided by .1 is 250
going back and checking my work:
50 + .35 (250) = 137.5
75 + .25(250) = 137.5
So the answer is 250 miles
Step-by-step explanation:
(a) 15% of $ 6000 = 5/100 × 600= &30
value after x years =$ 6000 -$ 30x
(b) value after 6 years = $ 600 - & 180 = $ 5820
Answer:
