The slope is the same as the gradient
y=mx+c where m is the gradient and c is the y intercept
y=-5x-9
Therefore the 'slope' is -5 i.e. it goes down 5 every 1 across.
ANSWER
C) V=πr²h
EXPLANATION
The formula for calculating the volume of a prism is

where B represents the area of the base and h represents the height of the prism.
A cylinder is a prism with a circular base.
Therefore area of the base is

Therefore the volume of the cylinder is

The correct choice is C.
In other words, it's asking what fraction is $6.30 out of $35. So let's make a fraction.

Remember that the fraction sign is a division sign. So 6.30/35 = 6.30<span>÷35, which equals 0.18.
Converting the decimal 0.18 to a percent, multiply by 100 (move decimal two places to the right) and tag the % sign at the end.
0.18 = 18%</span>
The correct answer is
D) 1/2
because
5/10 = 1/2
