What Must Be The Length Of PQ In Order For AJKL To Besimilar PQR

Answers

Answer 1

9514 1404 393

Answer:

  (d)  18

Step-by-step explanation:

If ΔJKL ~ ΔPQR, then we must have ...

  PQ/JK = QR/KL . . . . . ratios of corresponding sides are the same

  PQ = JK×QR/KL = 12×9/6 = 2×9

  PQ = 18

Answer 2

Answer:

18

Step-by-step explanation:

The scale factor for this is 1.5,

JL = PR

JL is 14, and PR is 21, 14 * 1.5 = 21

KL = QR

KL is 6, and QR is 9, 6 * 1.5 = 9

So we do the same for JK and PQ

Since PQ is 12, we need to find what 12 * 1.5 is.

12 * 1.5 = 18

PQ = 18

Suppose that the value of a stock varies each day from $12.82 to $33.17 with
a uniform distribution.
Find the third quartile; 75% of all days the stock is below what value?

Answers

Answer:

$28.08

Step-by-step explanation:

$33.17 - $12.82 = $20.35

75% of $20.35 = $15.26

$15.26 + $12.82 = $28.08

Hey guys. I just need someone's help to clarify things with me.

As I was doing the equations, I got to:

x^-1
-----
x^13

I moved the x^-1 down to x^13 so they'd subtract. But when I did, x^-1 became positive.

So it became x^13 times x^1

Radical Rule: a^n x a^m is pretty much a^n+m

So my answer was 14.

How did x^-1 become positive in this case?

Answers

Step-by-step explanation:

Given [tex]\frac{x*x^{-2} }{x^{13}}[/tex]

= [tex]\frac{x*x^{-2} }{x^{13}} = \frac{x^{-1} }{x^{13}}[/tex]

According to the Negative Exponent Rule, [tex]a^{-n} = \frac{1}{a^{n}}[/tex]

Therefore, [tex]\frac{x^{-1} }{x^{13}} = \frac{1}{x^{1}*x^{13}} = \frac{1}{x^{13+1}}= \frac{1}{x^{14}}[/tex]

In other words,  [tex]x^{-1}[/tex] became positive because of the Negative Exponent Rule. Once you bring [tex]x^{-1}[/tex] down towards the denominator, you're essentially removing its negativity and turning its exponent into a positive value. Once that takes place, then you could apply the Product Rule of Exponents onto the exponents in the denominator, where it states, [tex]a^{m}a^{n} = a^{m+n}[/tex].

Answers

Answer:

The answer is B 10 L

Step-by-step explanation:

let milk and water in the mixture be 7x and 4x equal 55L

[tex]7x + 4x = 55 \\ 11x = 55 \\ x = 5[/tex]

[tex]7(5) = 35l \: milk \\ 4(5) = 20l \: water[/tex]

let x Liters of water he added so that the ratio is 7:6

[tex] \frac{35l \: milk}{20l \: water + x} = \frac{7}{6} [/tex]

cross multiply

[tex]35l \: milk \times 6 = (20l \: water + x)7 \\ 210l \: m= 140l \: w + 7x \\ 210l \: m - 140l \: w = 7x \\ 70l = 7x \\ \frac{70}{7} = \frac{7x}{7 } \\ x = 10 l \: water[/tex]
