Answer:

$x=8\frac34\ \,,\quad y=8\frac12$

Step-by-step explanation:

$\Delta TRS\sim \Delta LJK \quad\implies\quad \dfrac{|TR|}{|LJ|}=\dfrac{|RS|}{|JK|}=\dfrac{|ST|}{|KL|}\\\\\dfrac{4}{7}=\dfrac{5}{x}=\dfrac{6}{y+2}\\\\\\\dfrac{4}{7}=\dfrac{5}{x}\quad\implies\quad4x=5\cdot7\quad\implies\quad x=\dfrac{35}4=8\frac34\\\\\\\dfrac{5}{x}=\dfrac{6}{y+2}\quad\implies\quad 5(y+2)=6\cdot\dfrac{35}4\\\\5y+10=3\cdot\dfrac{35}2\\\\5y\ =\ \dfrac{3\cdot35}2-10\\ \div5\qquad\quad \div5\\\\y=\dfrac{3\cdot7}2-2=10\frac12-2=8\frac12$

*100 points* What is the value of x in these polygons?

Effectus [21]

Answer and Step-by-step explanation:

$Greetings!$

$Let's~answer~your~question!$

$Since~ we~ know~ that ~these ~two~ are~ similar, ~it ~is ~also~ given ~that~ corresponding\\ parts ~of ~the~ triangle~ are ~proportional.~ In ~result,~ you~ can~ set~ the~ proportions~\\something~ like~ this:$

$\frac{16}{32}= \frac{12}{24}$

$Now,~from~ here, you~ can ~figure~ out~ that~ the~ ratio~ of ~the ~larger ~triangle~ to ~the \\~smaller~ triangle~ is ~.75:1$

$You~can~ then~ apply~ this~ to~ the~ side ~of ~x-1 ~and ~set~ up ~the~ equation.$

$.75(x-1)=6$

$Now,~solving~ the~ equation,~ you~ get~ x=9.~ Substitute~ that~ into~ x-1~ and~ you\\ get~ 8 ~as ~that~ side~ length.~ To~ check, compare:$

$\frac{8}{6}=\frac{32}{24}$

$Thus,~the~value~of~x~is=9.$

$Hope~my~answer~helps~you!~Have~a~blessed~day~ahead!$

What is the probability that a point chosen inside the large rectangle is not in the shaded region?

Maurinko [17]

The shaded region has an area of 12 while the whole thing is 50 mutiply both by 2 to get the area of the shaded region and the whole thing by 100 After that subtract 24 from 100 and you get a 76 percent chance that you will randomly select an area in that box that isn't shaded.

Find the nth tearm<br><br>-5 -2 3 10 19

tresset_1 [31]

Given :

The sequence is -5 , -2 , 3 , 10 , 19 .

To Find :

The nth term of the given sequence .

Solution :

Difference between first 2 terms :

-2 - ( -5 ) = 3 1 term

3 - ( -2 ) = 5 2 term

10 - 3 = 7 3 term

19 - 10 = 9 4 term

From the above observation we can say that difference is increasing in odd number .

So, the nth term will be :

$a_{n+1}= -5 + (2n+1)$ for n greater than equal to 0.

Hence, this is the required solution.
