Answer: $12\ cm$

Step-by-step explanation:

The first step to solve this exercise is to find the Scale factor.

By definition, the Scale factor is the ratio of the length of any side of one of the figures to the lenght of the corresponding side of the other one.

Based on this, you get that, in this case, the Scale factor is:

$Scale\ factor=\frac{20\ cm}{5\ cm}\\\\Scale\ factor=4$

Therefore, since you need to find the lenght of the side "A", you must multiply the lenght of the corresponding side of the other figure, by the Scale factor.

Then you get that the lenght of the side "A" is:

$Side\ A=(3\ cm)(4)\\\\Side\ A=12\ cm$

The relationship is a function. A function is an equation of graph that has no repeated x values. In this graph, each x value has a different y value, whether it's (1, 70) or (9,95)

If Rachel gets anything other than a 95, the x value of 2 will have more than one y value: 95 and whatever grade Rachel gets. Therefore it will no longer be a function.

Prove or disprove that if a and b are two rational numbers, then a b is also a rational number.

Harman [31]

That is not correct, In a quotient or any type of equation numbers are considered rational number when they have repeating values, for this we will use {x} for example when comparing repeating values.

So if we have {a} + {b} from a equation prior to obtaining these values then we will take {a} + {b} and add {c} we will end up with {a} + {b} + {c}. We are using addition for an example.

{c} would only be a rational if it as well had repeating {x} values

{x}=Repeating value

Ng Order of Operations George has $15. He would like to know if he has enough money to see a movie ($9.00) and buy a pretzel ($2

UNO [17]

Answer:

No, George does not have enough money to buy everything.

The correct expression is:

15 - 9 - 2.65 - 1.35 - 2(1.74)

Step-by-step explanation:

Given that:

Money present with George initially = $15

Money required to see the movie = $9

Money required to buy a pretzel = $2.65

Money required to buy a drink = $1.35

Money required to buy 2 veggie cups = $2(1.74)

To find:

Whether there is enough money with George to complete all the tasks.

Solution:

First of all, let us calculate all the money required and then we can subtract all the money from the initial amount to find whether there is enough money present with George.

If the result is in positive, there is enough money with George.

Total money required for all the activities = $9 + $2.65 + $1.35 + $2(1.74) = $16.48

Expression = $15 - $16.48 = -$1.48

The result is negative, therefore there is not enough money.

The correct expression is:

15 - 9 - 2.65 - 1.35 - 2(1.74)
