Answer:

x=13

Step-by-step explanation:

the angles shown are vertical angles so they are going to have the same value so to find x we setup an equation and the equation would be

-3x+14=-x-12 and the we solve for x

step 1 add 3x to each side

14=2x-12

step 2 add 12 to each side

26=2x

step 3 divide each side by 2

x=13

The average size of a certain computer datafile is 255 kilobytes. 10 million of these datafiles can be stored in a harddisk.
mr_godi [17]

Answer:

Hi! Your answer here is 2550 GB. To find this answer, we multiply 255 (the number of kb) by 10,000,000 (the number of files.) This gives us 2,550,000,000 KB. There are 1,000,000 kb in 1 GB, so we divide 2,550,000,000 by 1,000,000, which gives us 2550. 2550 GB of files can be stored.

Conservationists tagged 120 ​black-nosed rabbits in a national forest in 1990. In 1991​, they tagged 240 ​black-nosed rabbits in
Sauron [17]

Answer:

Hence after period of 9 years from 1990 t0 1999 will be 61438 rabbits.

Step-by-step explanation:

Given:

Population for rabbit obeys exponential law.

120 at 1990 and 240 1991 ...after 1 year time period

To Find:

After 9 year  time period how many rabbits will be there.

Solution:

Exponential law goes on present value and various value and time period and defined as ,

let Y be present value Y0 previous year value  and k exponential constant and t be time period.

So

Y=Y0e^(kt)

Here Y=240  ,Y0=120  t=1 year time period

So

240=120e^(k*1)

240/120=e^k

2=e^k

Now taking log on both side, [natural log]

ln(2)=ln(e^k)

ln(2)=kln(e)

k=ln(2)

k=0.6931

For t=9 year of time period

Y0=120,  t=9  ,k=0.6931

Y=Y0e^(k*t)

Y=120*e^(0.6931*9)

=120e^6.2383

=61438.48

=61438 rabbits

Describe how you can tell that a fraction corresponds to a repeating decimal and not a terminating decimal
horrorfan [7]
When a fraction corresponds to a repeating decimal, it's denominator is 9 or 99.

For example, 4/11 = 36/99 = 0.36 with bar notation over 36.

Example #2: 2/3 = 6/9 = 0.666....
or also written as 0.6 with bar notation over 6.

You know a fraction responds to a terminating decimal because it can be simplified to a terminating decimal.

Example: 2/4 = 0.5
