Answer:
∠ ABC = 116°
Step-by-step explanation:
Since the angles are supplementary, they sum to 180° , that is
8x - 36 + 4x - 12 = 180
12x - 48 = 180 ( add 48 to both sides )
12x = 228 ( divide both sides by 12 )
x = 19
Then
∠ ABC = 8x - 36 = 8(19) - 36 = 152 - 36 = 116°
The cost of the metals from the calculations performed is $ 402421.
<h3>What is density?</h3>
Density can be explained as a quantity having mass per unit volume and this can be calculated as:
Mass of the metal = ?
Density of the metal = 7.3 g/cm^3
height of the metal = 610 cm
radius of the metal = 8.7 cm
Volume of a cylinder can be calculated by using the formular below:
And this can be used by inserting the given values which is

Then we can calculate the mass as :
Mass = (density * volume)

=Since the cost is $0.38 per kilogram, then 3657 Kg costs
;( 1059003kg * $0.38)
= $ 402421

Answer:
y= -10x+200, x is equal to a week
Step-by-step explanation:
formula y=mx+b
we lose 10$ a week so the slope is -10 and we start with a base amount of 200
so plug those numbers in and you have y= -10x+200
