3y = -x + 3
y= (-1/3)x + 1
perpendicular: 3
y + 1 = 3(x - 6)
y + 1 = 3x - 18
y = 3x - 19
Answer:
The answer to your question is: It is not made of gold.
Step-by-step explanation:
Data
density = 19.32 g/cm³
side = 5 cm
height = 6 cm
mass = 942 g
Formula
V = 
L² = 5 x 5 = 25 cm²
V = 
V = 50 cm³
density = 942 g / 50 cm³
= 18.84 g/cm³
It is not made of gold because the density calculated is lower than the density reported in books.
Answer:
The measure of ∠A is 127°.
Step-by-step explanation:
The interior angles of a triangle always add up to 180°. Since you can fix <em>three</em> triangles into a pentagon, the sum of its interior of angles is 540° You could also look at how many angles there are (5), multiply that number by 180°, then subtract 360° from the product.
540° - (113° + 80° + 130° + 90°) = ∠A
540° - 413° = 127°
∠A = 127°

A=p(1+r/100)^n
A=2500(1+4/400)^16
A=2931.45
