Here is something you should know make answering these questions easier

Textbook questions #10,#12 and#17

#10

Kai uses an entire can of paint on the square backdrop for the school play. The label on the can states that one can cover 27m2 of wall surface. Estimate the backdrop's side length to one decimal place.

Way to get this

1. You make a number line
2. Find the halfway point and find what number it is
3. Add your number and find where it goes

#17

Carmel want to mount an 18cm by 18cm square on a square board that is four times the area of the picture.

a) What is the area for the picture.

b)What is the area of the board

c)What are the dimensions of the board.

Way to get this

1. To get the answer for a) you have to multiply 18cm by 18cm and you get the answer
2. To get the answer for b) you mulitply the area of the board which is 324 by 4 because the area of the board is 4 times of the picture
3. To get the dimension of the board you find the square root of 1296cm which is 36cm. You have to do this in your calculator.

#12

a) Estimate the side lengths of the rug to one decimal place.

b) Check your estimate with a calculator

c) Will the rug fit? Explain.

B) When you check on the caluclator it says 3.3 m

C) Yes the rug will fit becuasse the room is 20 m2 . The rug is only 11m by 9m

Parent Quiz

a(squared) + b(squared) = C(squared)
This Pythagorean Relationship means that the legs of the right triangle together equals to the hypotenuse, which is the longest side length of the right triangle. If the side lengths of the right triangle were not squared you would have to square them.Squared means to times it's number by it self, so it would be 6x6. So now you multiply the numbers, so oyu would multiply them 6x6 equals 36 and the other leg and together it would equal the hypotenuse.

Textbook Questions

I will be answering the 3 Textbook Questions # 10, 12 and 17.

For Number 10 it says:

The answer to that question is approximately 5.2. I got that answer by doing the following:

For Number 12, it says:

A)

Approximately 3.2 m.

B) According to the calculator, the right answer is 3.3 m

C) Yes, the rug will fit because the area of the room is 20^2 m, therefore, it is bigger than the rug which is 11 m^2 by 9 m.

For Number 17 it says:

A) The area of the picture is 324 m^2. I got that answer by going 18 x 18.

B) The area of the board is 1296 m^2. I got that answer by multiplying 18x18's product by 4.

C) The dimensions of the board is 36 x 36. I got the answer by finding the root of 1296 on a calculator.

Here is a game that may help you with remembering the perfect square numbers:

PARENT QUIZ:

1. The Pythagorean Relationship states that the ares areas of the two shortest sides of the right triangle, the legs, is supposed to equal the area of the longest side--the hypotenuse. The formulae for the Pythagorean Relationship is a² + b² = c². (C must always be the hypotenuse.)

2. c² = a² + b²

c² = 12² + 5²

c² = 144 cm + 25 cm

c² = 169 cm

Square root of 169 cm = 13 cm

c = 13 cm

3. c² = a² + b²

11² = 8 cm² + 6cm²

(8 x) + (6 x 6) = (11 x 11)

64 + 36 = 121

100 =/ 121

No, this is not a right triangle because the hypotenuse do not equal the legs therefore the formula c² = a² + b² does not work with it.
