Answer:

3391.2

Step-by-step explanation:

The formula for the volume of a cylinder is

pi * r^2 * h

Plugging the values in we get

3.14 * 6^2 * 30

= 3.14 * 36 * 30

= 3391.2

Choose the equation below that represents the line passing through the point (2, -5) with a slope of -3.

mash [69]

The point-slope form: $y-y_0=m(x-x_0)$

$m=-3;\ (2;-5)\to x_0=2;\ y_0=-5$

subtitute

$y-(-5)=-3(x-2)\\\\y+5=-3x+6\ \ \ \ \ |subtract\ 5\ from\ both\ sides\\\\\boxed{y=-3x+1}$

The sum of two numbers is negative. The product of these two same numbers is also negative. What can you conclude about these tw

lara [203]

Answer:

5 and -8

Step-by-step explanation:

One number must be negative since the product of the 2 number is negative (5 x -8 = -40). They both cannot be negative, if they were the product would then be positive. The negative number must have a absolute value that is larger than the positive, the negative numbers distance from 0 must be larger than the positive, -8 has a distance of 8 and 5 has a distance of 5. The sum of the two numbers is

=5 + (-8)

=5 - 8

= -3

baherus [9]

Answer:

$I=\frac{3}{8}\cdot F$ and $F = \frac{8}{3}\cdot I$ .

Step-by-step explanation:

Let I represent inches and F represent feet.

We have been given that on he scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is 16 feet.

We will use proportions to solve our given problem as:

$\frac{\text{Length on scale}}{\text{Actual length}}=\frac{6}{16}$
