<span>The goal of writing a number in scientific notation is to have a decimal number, with one digit to theleft of the decmial point, followed by a × 10to some power.
</span><span>
To format your number in this way, we'll divide the 245,893 by 10, 2time(s), making it a 2.45.
We do this, because each division by 10 moves the decimal point to the left one digit.
But in order to keep our number the same number, we must have a × 102next to the 2.45.
</span><span>
So, the final answer is 2.45 × 10<span>2 (: Hope im right!</span></span>
This is exponential growth/decay type problem...
F=Ir^t, F=final value, I=initial value, r=rate, t=time, in this case I=1250 and r=(1-.045)=0.955 so
F=1250(.955)^t and we want to find t for when F=800
800=1250(.955)^t
.64=.955^t take the natural log of both sides...
ln.64=t ln.955
t=(ln.64)/ln.995
t≈9.69 weeks
t≈9.69 weeks (to nearest hundredth of a week)
Answer:
9,000
Step-by-step explanation:
9474
Locate the thousands place:
<u>9</u>474
Check the number to the right:
9<u>4</u>74
If the number is greater than or equal to 5, we round up. If the number is less than or equal to 4, we round down.
Since there is a '4', we round down.
9474 ≈ 9000
Hope this helps.
Answer:
22
Step-by-step explanation:
8={1, 2, 4, 8}
12={1, 2, 3, 4, 6, 12}
GCF={4}
3(4)+10
=12+10=22
Based on the total amount of stamps that Noah has, we can calculate that those showing famous athletes number<u> 625 stamps. </u>
The percentage that shows famous athletes is:
<em>= 100% - U.S. Presidents - animals </em>
= 100% - 30% - 45%
= 25%
With a collection of 2,500 stamps, the number that is for famous athletes is:
= 2,500 x 25%
= 625 stamps
In conclusion, 625 stamps show famous athletes.
