Chuy wants to buy a new television. The television costs $1,350. Chuy decides to save the same amount of money each week, for 27
gavmur [86]

Answer:

Option (c)

Chuy will save more than he needs and will meet his goal in less than 27 week.

Step-by-step explanation:

Given that, Chuy wants to buy a new television. The television cost is $1,350.

He decides to save the same amount of money each week.

After 8 weeks he saved $440.

Each week he saved =\$\frac{440}{8}

                                 =$ 55

If he saved $55 each week.

At the end of 27 week he will save = $(27×55)

                                                          =$1485

Therefore he will save $1485 at the end of 27th week.

The saved money is more than the cost price of the television.

Therefore Chuy will meet his goal in less than 27 weeks.

Which of the following gives all of the sets that contain sqrt9?
Rudik [331]

Answer: C the set of all integers, the set of all rational numbers, and the set of all real numbers

Step-by-step explanation: The value of square root of 9 is ±3. This means that there two answers to square root of 9: 3 and -3.

As far as 3 is concerned, it is one of the elements of the natural number set. It is already known that natural numbers are also whole numbers, also integers, also rational numbers, and also real numbers.

As far as -3 is concerned, it is not a natural number since the set of natural numbers does not contain negative numbers. -3 is an integer. Which means that -3 is also a rational number and also a real number.

After identifying the common sets and taking the intersection of both the above classifications, it yields the set of all integers, the set of all rational numbers, and the set of all real numbers
