Since they are similar, that means they are proportionally the same.
So KL is similar to PN
JL is similar to PM

So,
You need to find how much bigger is the second triangle from first.
It is proportionally scaled up.

KL/JL = PN/ PM

You basically put in order of triangles. Left triangle on left side of equal sign and right triangle on right side of equal sign. You put in denominator the similar sides and numerator the similar sides (the side that is similar to the side of the other triangle)

5/6 = PN / 9
Cross-multiply
PN * 6 = 5*9
6PN = 45
PN =45/6

PN =7.5

HELP ME PLEASE <br> solve for the right triangle
ololo11 [35]

Answer:

XYsq = 9sq - 6sq

XY = √45 = 6.7 units

cosZ = 6/9 = .666

Z = 48.25°

sinY = 6/9 = .666

Y = 41.75°

hope it helps :D

Oxygen flows through one tube into a liter flask filled with air, and the mixture of oxygen and air (considered well stirred) es
yKpoI14uk [10]

The amount of oxygen in the flask through the intake tube illustrates proportions

The flask 99.35% will contain of oxygen after 5L have passed through the intake tube

<h3>How to calculate the percentage of oxygen?</h3>

To do this, we make use of the following representations

  • P for the proportion of oxygen
  • V for te volume of oxygen
  • x for the proportion of oxygen in the flask after 5 L passed through

So. we have the following derivative

dP = dV - P * dV

Divide through by dV

dP/dV  = 1 - P

Next, we set up the integral

\int\limits^x_{0.040}  \frac {1}{1 - P}dP= \int\limits^5_0 {dV}

Integrate both sides

-\ln(|P - 1|)|\limits^x_{0.04} = 5

Expand

-ln(|x - 1|) + ln(|0.04 - 1|) = 5

Evaluate the difference

-ln(|x - 1|) + ln(|-0.96|) = 5

Express as a fraction

ln(0.96/|x - 1|) = 5

Express both sides as exponents with a base of 2

e^ln(0.96/|x - 1|) = e^5

Solve for x

x = 1 - 0.96/e^5

Evaluate the difference

x = 0.9935

Express as percentage

x = 99.35%

Hence, the flask 99.35% will contain of oxygen after 5L have passed through the intake tube

What is the factored form of the equation 2(x-1)(8x-3)=0? Which ordered pairs are solutions to the system? Check all of the boxe
vovikov84 [41]

Answer:

  The solutions to the equation are 1, 0.375.

Step-by-step explanation:

The equation is already in factored form.

The solutions to the system are the values of x that make one or the other of the factors be zero.

  x -1 = 0 . . . when x = 1

  8x -3 = 0 . . . when x = 3/8 = 0.375

There is only one variable, so no "ordered pairs" are involved.

The solutions are {1, 0.375}.
