Answer:the number of stamps that his cousin collected is 20. The variable is x which represents number of stamps. The equation is
4x = 60
Step-by-step explanation:
Let x represent the number of stamps that his cousin collected.
Xander collected four times as many stamps as his cousin. This means that the number of stamps that Xander collected is 4x
If xander collected 60 stamps, then it means that
4x = 60
x = 60/4 = 20 stamps
B: (x' , y') = (1/2x, 1/2y) <-- Fractions
C: (x' , y') = (4x,4y)
D: (x' , y') = (2x,2y)
The expression representing two times the size of the original polygon is (x' , y') = (2x,2y), hence, option (D) is the correct answer.
A dilation is a transformation that yields a picture that differs in size while maintaining the original image's shape.
The size of the polygon will be doubled if its coordinates are multiplied by 2.
The expression representing the two times the size of the original polygon is (x' , y') = (2x,2y)
Hence, option (D) is the correct answer.

Find 12 1/2% of 96 men
percent of 96 men is 12 men.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, % of 96 men.
Here, % =12.5%
Now, 12.5% of 96
12.5/100 ×96
= 0.125×96
= 12 men
Therefore, percent of 96 men is 12 men.

Answer:
a) f(16) = 42
b) f(16) = 54
c) f(16) = 162
d) f(16) = 30
Step-by-step explanation:
a) y = mx + b ∧ m = (f(8) - f(4))/(8-4) ⇒ m = (18 - 6)/(8 - 4) = 3
b = y - mx = 6 - 3(4) = 6 - 12 = - 6
f(16) = 3(16) - 6 = 42
b) y = kxⁿ ∧ f(4) = 6 = k4ⁿ ∧ f(8) = 18 = k8ⁿ ⇒ 18/6 = (k8ⁿ)/(k4ⁿ) ⇒ 3 = 2ⁿ
n = ㏑(3) / ㏑(2) ⇒ k = y/xⁿ ⇒ k = 6/4ⁿ = 2/3
f(16) = 2/3 × 16ⁿ = 54
c) y = aeᵇˣ ∧ f(4) = 6 = aeᵇ⁴ ∧ f(8) = 18 = aeᵇ⁸ ⇒ 18/6 = (aeᵇ⁸)/(aeᵇ⁴) ⇒ 3 = e⁴ᵇ
b = ㏑(3/4) ∧ a = y / eᵇˣ ⇒ a = 6 / e⁴ᵇ = 2
f(16) = 2eᵇ¹⁶ = 162
d) y = a㏑(bx) ∧ f(4) = 6 = a㏑(b4) ∧ f(8) = 18 = a㏑(b8)
⇒ 18 - 6 = a㏑(b8) - a㏑(b4) ⇒ 12 = a㏑(8b/4b) ⇒ a = 12 / ㏑(2)
f(4) = 6 = a㏑(4b) ⇒ b = (√2)/4
f(16) = a㏑(b16) = 30
