It’s b if i’m not mistaken
Answer:
Step-by-step explanation:
5y + 6y + 7y = 18y......any numbers that add(or subtract) to equal 18, stick them before the y....
or it could be : 10y + 10y - 2y = 18y or 5y + 10y + 3y or 30y - 20y + 8y....I could go on forever...lol
Answer:
b. y = -9
Step-by-step explanation:
A line with zero slope has no dependence on x. It is simply ...
... y = constant
The constant must be the same as the y-value of the point you want the line to go through. Since the point is (12, -9), the constant is -9 and the equation is ...
... y = -9
The mass of lead cylinder is: 859.10 grams
Step-by-step explanation:
In order to find the mass of a cylinder we have to find the volume first
Given
Radius = r = 2 cm
Height = h = 6 cm
The volume of cylinder is given by:

Putting the values

Now,
Density of lead per cm^3 = 11.4g

The mass of lead cylinder is: 859.10 grams
