katrin [286]

1.1x+1.2x-5.4=-10x

Move all terms to the left:

1.1x+1.2x-5.4-(-10x)=0

Add all the numbers together, and all the variables

2.3x-(-10x)-5.4=0

Get rid of parentheses

2.3x+10x-5.4=0

Add all the numbers together, and all the variables

12.3x-5.4=0

Move all terms containing x to the left, all other terms to the right

12.3x=5.4

x=5.4/12.3

x=3.8571428571429/8.7857142857143

Hope it helps!

A horizontal curve is being designed around a pond with a tangent length of 1200 ft and a central angle of 29.86 degrees. If the

lara31 [8.8K]

Answer:

The correct answer is "1287.02 ft"

Step-by-step explanation:

Given that:

T = 1200 ft

PI = 145+00

$\Theta$ = 29.86°

or,

= 0.5211 rad

As we know,

The radius of curve is:

⇒ $T = R \ tan\frac{\Theta}{2}$

$1200=R \ tan(\frac{0.5211}{2} )$

$1200=R \ tan(0.267)$

$R = 4494.38 \ ft$

The length of curve will be:

⇒ $L=R \Theta$

$=449.38\times 0.5211$

$=2342.01 \ ft$

hence,

Station PT will be:

= $PI-T+L$

= $145-1200+2341.01$

= $1287.02 \ ft$

Given that X={whole numbers less than 24}

hodyreva [135]

Step-by-step explanation:

X= {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23}

P= {2,3,5,7,11,13,17,19,23}

Q= {2,4,6,8,10,12,14,16,18,20,22}

a= {2,3,4,5,6,7,8,10,11,12,13,14,16,17,18,19,20,22,23}

b= {2,}

c= we first find p'

p'={1,4,6,8,9,10,12,14,15,16,18,20,21,22}

c={4,6,8,10,12,14,16,18,20,22}

d=we do same here but we already have p' so we find for q'

q'={1,4,6,8,9,10,12,14,15,16,18,20,21,22}

d={1,4,6,8,9,10,12,14,15,16,18,20,21,22}
