Answer:

d=9

Step-by-step explanation:

The gradient of straight line is given by

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in our knows

$4=\frac{17-9}{d-5} \text{ Solve for d} \\\\4(d-5)=8\\\\d-5=4\\d=9$

Find the ratio of the volume of one sphere to the volume of the right cylinder

yarga [219]

Answer:

Step-by-step explanation:

Let $r$ be the radius of one sphere.

Volume of sphere is $V=\frac{4}{3}\pi r^3$

Since radius is r, the height of the cylinder will be $4r$

Also, the cylinder has the same radius as the sphere: $r$

Volume of Cylinder is $V=\pi r^2 h$

Plugging in the values we get: $V=\pi (r)^{2}(4r)=4\pi r^3$

Ratio of volume of 1 sphere to volume of cylinder is:

$\frac{\frac{4}{3}\pi r^3}{4\pi r^3}=\frac{\frac{4}{3}}{4}=\frac{4}{3}*\frac{1}{4}=\frac{1}{3}$

The ratio is 1:3

Answer choice B is right.

The value of y varies directly with x and y = 4.5 when x = 0.5. find y when x = 10

Pepsi [2]

So what you asked this is what I got

x(y) = 4.5

If x= 0.5 then

0.5(y) = 4.5
y=9

x(y) = 4.5

10(y) = 4.5
y= 0.45

hope this helps :)

What is the equation of a vertical line passing through the point (-4, 7)?

MrRa [10]

Answer:

x=-4

Step-by-step explanation:

Since we know that the equation will be x= we will just have to take the x value of the coordinate point and that would be the x so in this case the x is -4 so the equation would be x=-4
