Answer:

Dude

the twice of ML is equal to JL....

Now u may ask how can I say this the reason is I used "THE MIDPOINT FORMULAE" do search this concept on utube........

2(5x-16) = 4x+34

So here x is 11

Put the value of it in JL.... so JL is 4*11+34 = 78 units......

Find the missing segment.
Bond [772]

Answer:

? = 7.

Step-by-step explanation:

The two triangles are similar because of the AA Theorem.

The larger triangle's side that is equal to 9 + 3 corresponds to the smaller triangle's side length of 9, while the larger triangle's 21 + ? side corresponds to the smaller triangle's 21 side. Now, we can set up a proportion!

\frac{9}{9+3} =\frac{21}{21 + ?}

\frac{9}{12} =\frac{21}{? + 21}

\frac{3}{4} =\frac{21}{? + 21}

\frac{1}{4} =\frac{7}{? + 21}

? + 21 = 7 * 4

? + 21 = 28

? = 28 - 21

? = 7

Hope this helps!

I need help answering this question
My name is Ann [436]

Answer:

55

Step-by-step explanation:

JL = JK + KL

84 = 3x+5  + 6x+7

Combine like terms

84 = 9x +12

Subtract 12 from each side

84-12 = 9x+12-12

72 = 9x

Divide by 9

72/9 = 9x/9

8 =x

We want KL

KL = 6x+7

   6*8 +7

    48+7

     55

Iodine-125 has a half-life of about 60 days. How many milligrams of a 500 mg sample will remain after 300 days?
just olya [345]

60 x 5 = 300 days

So five half-lifes = 300 days

Starting amount = 500mg

<span>Amount after 1st half-life = 250 mg</span>

<span>Amount after 2nd half-life = 125 mg</span>

<span>Amount after 3rd half-life = 62.5 mg</span>

<span>Amount after 4th half-life = 31.25 mg</span>

<span>Amount after 5th half-life = 15.625 mg</span>

<span>Hence after 300 days, the amount of iodine-125 will be 15.625 mg out of 500 mg.</span>
