Answer:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. If they are inversely proportional, an increase in the value of one variable would cause a corresponding decrease in the other variable.

Looking at the given values, as x is increasing, y is also increasing. The constant of proportionality is

9/3 = 27/9 = 3

Therefore, the relationship is a direct variation and the function to model it is

y = 3x

Liam has $250. Then, he and his classmates bought a present for their teacher, evenly splitting the $p cost among the 24 of them

Semenov [28]

Answer: The required expression will be

$\frac{6000-p}{24}$

Step-by-step explanation:

Since we have given that

Amount that Liam has = $250

Amount that he and his classmates spent on present for their teacher =$p

Number of students in which $p will split = 24

According to question,

Amount that left to Liam is given by

$250-\frac{p}{24}\\\\=\frac{6000-p}{24}$

Hence, the required expression will be

$\frac{6000-p}{24}$

Write a few sentences explaining how to determine whether a relation shown in a table or a graph is a function.

ohaa [14]

Answer:

y=f(x)

y=5x

y=3x

are examples of function

Step-by-step explanation:

definition of a function

if there is one to one relation between a relation

then it is defined as a function

for example

y=5x is a function

because when we put some value of x it gives back only one value of y as output.

y=±5x is not a function because one value of x gives two values(positive and negative) values of y hence not a function.

There are two right circular cylinders. The radius of the first cylinder is 4 centimeters, and its height is 5 centimeters. The

Lina20 [59]

Answer:

D. 9:1

Step-by-step explanation:

The formula for the volume of a cylinder is πr² · h (pi · radius² · height) (use 3.14 for pi).

The two right circular cylinders have the same height. The larger cylinder has a radius that is three times the size of the smaller radius.

4 · 3 = 12

However, in the equation for volume, the radius is squared. Because of this, the larger cylinder is 9 times the size of the smaller cylinder because 3² = 9.

You can check your work by finding the volume of the two cylinders using the volume formula πr² · h:

3.14 · 4² · 5 = 251.2

3.14 · 12² · 5 = 2,260.8

The cylinder with a radius of 12 cm is 9 times the size of the cylinder with a radius of 4 cm.

2.260.8 ÷ 9 = 251.2
