Tangents to a circle from the same point are equal length. Thus, for example, the two segments at the upper left (to A and to D) are both length 4. The ones at lower left are both length 6.

Then
x = 4+6
x = 10

The perimeter is twice the sum of the lengths shown, so is
perimeter = 2(4 + 8 + 3 + 6)
perimeter = 42

A manager must select three coders from her group to write three different software projects. There are 7 junior and 3 senior co

gavmur [86]

Answer:

The total number of ways are 168.

Step-by-step explanation:

Consider the provided information.

There are 7 junior and 3 senior coders in her group.

The first project can be written by any of the coders. The second project must be written by a senior person and the third project must be written by a junior person.

For second project we have 3 choices and for third project we have 7 choices.

Now there are 2 possible case:

Case I: If first and second coder is senior, then the total number of ways are:

$3\times 2\times 7=42$

Case II: If first and third coder is junior, then the total number of ways are:

$7\times 3\times 6=126$

Hence, the total number of ways are: 42+126=168

If y=12 when x=3, find y when x =15 ( Y varies directly as x)

Flauer [41]

Y = kx
when y= 12, x=3
12 = 3k
k = 12/3
k = 4

y = 4x
when x= 15
y = 4(15)
y = 60
