8+6=14
14+5=19
The length of the 2D cross-section = 22cm
Breadth of 2D cross-section = 12cm
Since it's inside a rectangular prism, it's area will be given by the formula of area of a rectangle.
→ Area of 2D cross-section = 22×12 = 264 cm²
3x+50+6x-10=180
I combined the two equations and now you can solve for x
start by adding 3x plus 6x and subtracting 10 from 50 and you get a new equation
9x +40 =180
now from here you should be able to do the rest
just subtract 40 from 180 to get 9x=140
and what is 140 divided by 9
The height of the candle after 8 hours is 19.2 centimeters
<h3>How to determine the height of the candle after 8 hours?</h3>
The given parameters are:
Slope, m = -0.6
Points: (x, y) = (17, 13.8)
A linear equation can be represented as:
y = m(x - x1) + y1
Substitute the points (x, y) = (17, 13.8) in the above equation y = m(x - x1) + y1
So, we have
y = m(x - 17) + 13.8
The slope is -0.6
So, we have:
y = -0.6(x - 17) + 13.8
After 8 hours, we have
x = 8
Substitute x = 8 in y = -0.6(x - 17) + 13.8
y = -0.6(8 - 17) + 13.8
Evaluate
y = 19.2
Hence, the height of the candle after 8 hours is 19.2 centimeters
