Is .21 (with only the one repeating) a rational number? please explain why! thanks!
Nostrana [21]

21 is a rational number because it is an integer, which can be converted into a fraction.

<u>Step-by-step explanation:</u>

When a denominater and numerator are integers and gives a quotient then it is a rational number.

21/1, where 21 is denominator and 1 is numerator the quotient is 21. Therefore 21 is a rational number which can also be considered as a ratio.

5. Find the lateral surface area of the net of<br> the cube.<br> 1.8 cm
igor_vitrenko [27]

<u>Given</u>:

Given that the side length of the cube is 1.8 cm

We need to determine the lateral surface area of the cube.

<u>Lateral surface area of the cube:</u>

The lateral surface area of the cube can be determined using the formula,

LSA=4a^2

where a is the side length.

Substituting a = 1.8 in the above formula, we get;

LSA=4(1.8)^2

Squaring the term, we get;

LSA=4(3.24)

Multiplying, we get;

LSA=12.96

Thus, the lateral surface area of the cube is 12.96 cm²

Please hurry, 15 points and it's overdue.
valina [46]

Answer:

The relationship is positive.

The model predicts a score of 60.

Not sure what part b is.

Step-by-step explanation:

Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.

By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
