HEy!!
So you drive 25 miles / hour.
Which is equal to 225 miles / number for hours driven
then 25 miles/ 1 hour = 225 miles / number of hours.
distance / speed = time
225 / 25 = time
time = 9
9 miles/hr
7 is a prime number because it is only divisible by 1 and itself which is 7.
Answer:
-2.8 / 4
Step-by-step explanation:
This is basically a simple problem to understand. The only thing that needs to be done is to divide the mass of the sun by the mass of mercury. It will give the required result.
Number of times the mass of sun is greater than
the mass of mercury = 21.3525×102921.3525×1029/<span>328.5×1021328.5×1021
= </span><span>7.1783629e+15
I hope that this is the answer that you were looking for and it has come to your great help.</span>
<span>the line over the 28 means the 28 repeats forever.
1.282828.... and so on
let x be the rational number 1.28...
we can use this trick:
100*1.282828....= 128.282828... (the decimal 28 part repeats)
100x = 128.28...
next:
100x - x = 128.282828... - 1.282828...
the .282828... part will be subtracted away
99x = 127
divide both sides by 99 to get
x= 127/99</span>
