NOT is coded as LKF and FLY is coded as TNA, then which of the following word/s has/have correct coding? (1) TOP – FKJ (2) RUN –
AVprozaik [17]

Answer:

  • (1) and (3) are correct options

Step-by-step explanation:

  • NOT is coded as LKF
  • FLY is coded as TNA

<u>Using alphabet, we can see that:</u>

NOT = 14, 15, 20  ⇔ 13+1, 13+2, 13+7 ⇒ LKF = 12,11,6 = 13-1, 13-2, 13-7

Coding for each letter is 13 + x ⇒ 13 - x

(1) TOP ⇒ FKJ

  • TOP = 20,15,16 ⇒ 13-7, 13-2, 13-3 =  6,11,10 = FKJ
  • Correct

(2) RUN ⇒ IFM

  • RUN = 18,21,14 ⇒ 13-5,13-8,13-1 = 8,5,12 = HEL ≠ IFM
  • Incorrect

(3) MUG ⇒ MES

  • MUG = 13,21,7 ⇒ 13+0, 13-8, 13+6 = 13,5,19 = MES
  • Correct

(4) HOT ⇒ RKG

  • HOT = 8,15,20  ⇒ 13+5,13-2, 13-7 = 18,11,6 = RKF ≠ RKG
  • Incorrect

A b c or d please hurry thanks!
otez555 [7]

Answer:

C)  a = 10√3, b = 5√3, c = 15 , d = 5

Step-by-step explanation:

Here we use the ratio of 30, 60, 90 degree triangle.

The ratio of sides, 1:√3:2

2x = 10

x = 5

d = 5

b = 5√3

c = 5√3√3

c = 5*3 = 15

c = 15

a = 2(5√3)

a = 10√3

Therefore, a = 10√3, b = 5√3, c = 15 and d = 5

Thank you.

What is the distance between the two points (-8,-6) and (-2,4)?
MAVERICK [17]

Answer:

\sqrt{136} = 11.66 units

Step-by-step explanation:

distance between 2 points (a,b) and (c,d) = \sqrt{(a^{2}-c^{2} ) +(b^{2}-d^{2} ) }

= \sqrt{((-8)^{2}-(-2)^{2} ) + ((-6)^{2}-4^{2})   }

=\sqrt{136}

= 11.66 units
