A company produces screens of different sizes. Based on the table, could there be a relationship between the number of pixels and the area of the screen? If so, write an equation representing the relationship.

Answers

Answer
1 in =5184
Step by step

The equation representing the given situation is y = 5184x.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

There are given values for the square inches of screen and the number of pixels.

If there is a proportional relationship between the number of pixels and the area of the screen,

the equation will be of the form y = kx, where k is a constant of proportionality.

31,104 = 6k

k = 31,104 / 6 = 5184

373,248 = 72k

k = 373,248 / 72 = 5184

544,320 = 105k

k = 544,320 / 105 = 5184

1,555,200 = 300k

k = 1,555,200 / 300 = 5184

The equation is, y = 5184x

Hence the equation is y = 5184x.

Answers

Answer:

1) the ratio is 15: 29    2) 25% of 80 = 20   3) C

Step-by-step explanation:

Two ratios are equivalent if they represent the same number. A rate is a special ratio that compares two quantities that have different units of measure. If the second term in a rate is 1, the ratio is called a unit rate. Unit rates are often described as a quantity per unit of time or per item.
