This is simple you just need to think what minus or plus the variable in each equation (letter that represents an unknown number) equals what the equations do

No. 19 X= -8
No.20 R=10
No.21 X=0
No.22 B=7
No.23 V=-4
No.24 N=10
No.25 X=7

Answer:

Part a) The radii are segments AC and AD and the tangents are the segments CE and DE

Part b) $DE=4\sqrt{10}\ cm$

Step-by-step explanation:

Part a)

we know that

A radius is a line from any point on the circumference to the center of the circle

A tangent to a circle is a straight line which touches the circle at only one point. The tangent to a circle is perpendicular to the radius at the point of tangency.

In this problem

The radii are the segments AC and AD

The tangents are the segments CE and DE

Part b)

we know that

radius AC is perpendicular to the tangent CE

radius AD is perpendicular to the tangent DE

CE=DE

Triangle ACE is congruent with triangle ADE

Applying the Pythagoras Theorem

$AE^{2}=AC^{2}+CE^{2}$

substitute the values and solve for CE

$14^{2}=6^{2}+CE^{2}$

$CE^{2}=14^{2}-6^{2}$

$CE^{2}=160$

$CE=\sqrt{160}\ cm$

$CE=4\sqrt{10}\ cm$

remember that

CE=DE

$DE=4\sqrt{10}\ cm$

A typical song downloaded from the internet is 4 megabytes in size. Lindy has satellite internet, and her computer downloads mus

nasty-shy [4]

So the first thing you do is you divide 1024 by 256. you will come out with the answer of 4. it takes 4 seconds to download 1 megabyte. but, it takes 4 megabytes, so you need to multiply 4 by 4. you will get 16. it takes 16 seconds to download 1 song.

to figure out how many songs Lindy can download in 2 hours, you multiply 60 by 60. you will get an answer of 3600. there are 3,600 seconds in an hour. now to find out how many are in 2 hours you multiply 3,600 by 2. you will get a sum of 7,200

now to figure out how many songs Lindy can download in 2 hours, you divide 7,200 by 16. you will come out with a quotient of 450.

Lindy can download a total of 450 songs in the space of 2 hours.
