(PLEASE HELP ASAP!!). One's intelligence quotient, or IQ, varies directly as a person's mental age and inversely as that person'

shusha [124]

Answer:40

Step-by-step explanation:This is a variation question

From the statement. Let the mental age be M and the chronological age be C, then

IQ ∝M ∝1/C

⇒ IQ ∝ M/C

Introducing the proportionality constant

IQ = KM/ C

Given : M = 15, C = 30 , 1Q = 20

Substitute the given values into the equation

i.e 120 = K x 15/ 30

120 = k/2

therefore k = 240

substitute k = 240 into the equation, we have

IQ = 240M/C

To find C when IQ is 120 and M is 20, we will substitute into the generated formula

i.e 120 = 240 x 20 / c

120c = 480

C = 480/120

C = 40

Therefore , the chronological age of a person with mental age of 20 and IQ of 120 is 40

Answer:

B) 63°

Step-by-step explanation:

Step 1: find the angle beside x (inside the pentagon)

*A pentagon has a total of 540°

119 + 100 + 116 + 88 = 423

540 - 423 = 117

Step 2: x is a supplementary angle, which means it's angle adds up to 180°

Since we know the other angle is 117°, we just subtract that from 180

180 - 117 = 63

x = 63
