Answer:

There is not enough information to answer this problem.

Step-by-step explanation:

A proportional function means that if you change X, Y will change in the same proportion. And that proportion of change will remain the same no matter which two values of X you take to compare them.

But that proportion will vary from function to function.

Without knowing what the function is, it's impossible to know the value of Y for a given X... it could be anything.

A cylinder and a cone have the same diameter:8 inches. The height of the cylinder is 3 inches.The height of the cone is 18 inche

sesenic [268]

The volume of cone is double of the volume of cylinder.

Further explanation:

We have to find both volumes first to compare the volumes of both.

Volume of Cylinder:

Given

Diameter = d = 8 inches

$Radius=r=\frac{d}{2}=\frac{8}{2}=4\ inches$

Height of cylinder=h=3 inches

$V_{Cyl}=\pi r^2h\\=3.14*(4)^2*3\\=3.14*16*3\\=150.72\ in^3$

Volume of Cone:

Radius=r=4 inches

Height of cone= h= 18 inches

$V_{con}=\frac{1}{3}\pi r^2h\\=\frac{1}{3}*3.14*(4)^2*18\\=\frac{1}{3}*3.14*16*18\\=301.44\ in^3$

We can see that

$2V_{cyl}=V_{Con}$

The volume of cone is double of the volume of cylinder.

An animal shelter has $2500 in its reserve fund. The shelter charges $40 per animal placement and would like to have at least $4

Elena-2011 [213]

Answer:

Step 1

Write and solve the inequality:

2,500 + 40a ≥ 4,000, or 40a ≥ 1,500

a ≥ 37.5

Step 2

If the shelter places 30 cats and 10 dogs,

or 40 animals, that will be enough to meet

its goal, because a = 40 is a solution to the

inequality a ≥ 37.5.

A driver travels a distance of 119 miles between 09:50 and 11:35. Work out the average speed of the driver

AURORKA [14]

Answer:

68 miles per hour.

Step-by-step explanation:

The time taken for the driver to drive 119 miles is 105 minutes.

The average speed is equal to distance divided by the time taken.

105 minutes is equal to 1.75 hours.

$S=119/1.75$

$S =68$

The driver's average speed is 68 miles per hour.
