6. a) Calculate the areas of the three squares. b) Is the triangle a right triangle? Explain. 3 cm 4 cm 2 cm

viktelen [127]

Answer

The total area of the squares = 29 square cm

The triangle is not a right-angled triangle

Step-by-step explanation:

We are given three squares

The first square has a length of 4cm

The second square has a length of 3cm

The third square has a length of 2cm

Part A

Total area = Area of square 1 + Area of square 2 + Area of square 3

Area of a square = l^2

Where l is the length of the square

Area of a square 1 = 4^2

Area of a square = 16 square cm

Area of square 2 = 3^2

Area of square 2 = 9 square cm

Area of square 3 = 2^2

Area of square 3 = 4 square cm

Total area of the square = 16 + 9 + 4

The total area of the square = 29 square cm

Hence, the total square of the figure is 29 square cm

Part B

$\begin{gathered} \text{ To proof if the triangle is a right angled triangle} \\ \text{ We n}eed\text{ to appy Pythagora's theor}em \\ \text{Hypotenus}^2=perpendicular^2+base^2 \\ \text{Hypotenus = 4}cm \\ \text{Perpendicular =3cm} \\ \text{Base = 2cm} \\ 4^2=3^2+2^2 \\ 16\text{ = 9 + 4} \\ 16\text{ }\ne\text{ 13} \\ \text{ Since the hypotenus is not equal to the summation of the perpendicular and base} \\ \text{Hence, the triangle is a not right angled triangle} \end{gathered}$

What’s the correct answer for this?

jok3333 [9.3K]

Answer:

1/2

Step-by-step explanation:

The formula that relates two independent events is provided as below:

P(A) x P(B) = P(A⋂B)

=> P(A) x (1/3) = 1/6

=> P(A) = (1/6) x 3

=> P(A) = 3/6 = 1/2

=> Option D is correct

Hope this helps!

There are 4 cups in 1 quart. To wash windows, 2 cups of Rid-a-Spot are to be mixed with 5 cups of water. How many quarts of this

Rama09 [41]

Answer:

3.5 quarts of this mixture can be made from the 1-quart container of Rid-a-Spot.

Step-by-step explanation:

2 cups of Rid-a-Spot are to be mixed with 5 cups of water.

Then cups of water require for 1 cup of Rid-a-Spot = $\frac{5}{2} cup=2.5 cup$

Given : 4 cups = 1 quart

$1 cup=\frac{1}{4} quart=0.25 quart$

$2.5 cup=\frac{2.5}{4} quart=0.625 quart$

So, 0.25 quart of Rid-a-Spot requires 0.625 quarts of water.

Then 1 quart of Rid-a-Spot requires :

$\frac{0.625 quarts}{0.25}=2.5 quart$ of water

Total volume of the mixture = 1 quart + 2.5 quart=3.5 quart

3.5 quarts of this mixture can be made from the 1-quart container of Rid-a-Spot.
