it had to be b cuz now all quadrilateral have straight sides
Answer:
31.5 litres
Step-by-step explanation:
If Mel uses all 30 litres of yellow paint, then:
5 / 2 = 30 / x
5x = 60
x = 12
Mel would need 12 litres of blue paint, but she only has 9 litres. So the amount of yellow paint she needs is:
5 / 2 = x / 9
2x = 45
x = 22.5
Mel will use 22.5 litres of yellow paint with 9 litres of blue paint to make a total of 31.5 litres of green paint.
In order for a function to be odd, we know that f(-x) = -f(x)
Hence, the only graphs that are odd are the cubics.
Now, a monomial is defined as an equation with only one term in it. Since the first two is shifted, they must consist of at least 2 terms.
Hence, the only viable answer is the third graph.
The formula for half-life is:

A is the amount remaining, P is the initial amount, t is the time that has passed, and h is the half-life of the substance. Plug in the values that you know and solve:

Rounded to the nearest whole number, the density of the substance was about 13<span>mg / cm².</span>
