Answer:

x-2x-6=8x+12-x-4

-x-6=7x+8

Step-by-step explanation:

solve

x-2(x+3)=4(2 x+3)-(x+4)

x-2x-6=8x+12-(x+4)

-x-6=7x+8

use the picture to write each ratio as a simplified fraction (how are you going to find the length of the third side?) show your

Butoxors [25]

Answer:

<h3>See below</h3>

Step-by-step explanation:

to figure out the ratios we must figure out the length of <u>hypotenuse</u> first to do so we can consider <u>Pythagoras</u><u> theorem</u> given by

$\displaystyle {a}^{2} + {b}^{2} = {c}^{2}$

$\displaystyle \implies c = \sqrt{ {a}^{2} + {b}^{2} }$

substitute:

$\displaystyle c = \sqrt{ {12}^{2} + {9}^{2} }$

simplify squares:

$\displaystyle c = \sqrt{ 225 }$

simplify square root:

$\displaystyle c = 15$

now recall that,

$\displaystyle \sin( \theta) = \frac{opp}{hypo}$
$\displaystyle\cos( \theta) = \frac{adj}{hypo}$
$\displaystyle \tan( \theta) = \frac{opp}{adj}$

the ratios with respect to angle w given by

$\displaystyle \sin( W) = \frac{12}{15} = \frac{4}{5}$
$\displaystyle \cos(W) = \frac{9}{15} = \frac{3}{5}$
$\displaystyle \tan( W) = \frac{12}{9} = \frac{4}{3}$

the following ratio with respect to angle X

$\displaystyle \sin(X) = \frac{9}{15} = \frac{3}{5}$
$\displaystyle \cos(X) = \frac{12}{15} = \frac{4}{5}$
$\displaystyle \tan( X) = \frac{9}{12} = \frac{3}{4}$

There are 8 runners in a race.

lesya692 [45]

STEP 1:
Total runners originally= 8
# of runners to receive trophies= 4

8-2 drop outs= 6 runners total now

STEP 2:
= # of trophies ÷ total runners now
= 4/6
simplify by 2
= (4÷2)/(6÷2)
= 2/3 runners

ANSWER: 2/3 of the remaining runners will win a trophy.

Hope this helps! :)
