A rectangular window is 2 feet by 3 feet. About how long is the diagonal of the window?

Answers

Answer:

3.6 feet

Step-by-step explanation:

The diagonal of a rectangle is a hypotenuse of the triangle with legs equal to sides of the rectangle

Using Pythagoras to find its value:

d = √2²+3² = √13 = 3.6 feet
Since its going by 2 feet by 3 feet we should multiply 3x2 and we get 6 but since 2 and 3 or on Botha sides it’s 3.6

Amanda makes 3 biscuits in 2 minutes. How many biscuits can she make in 30 minutes?

Answers

45 because 30 divided by 2 is 15 the 15 times 3

Amanda makes 45 biscuits in 30 minutes which is determined by the ratio.

What is Ratio?

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that Amanda makes 3 biscuits in 2 minutes.

Let the number of biscuits would be x

To determine the number of biscuits can she make in 30 minutes.

According to the given question, we can write the ratio as:

3 biscuits : 2 minutes = x biscuits : 30 minutes

⇒ 3 / 2 = x / 30

Apply the cross-multiplication operation

⇒ x = (30 × 3) / 2

Apply the multiplication operation

⇒ x = 90 / 2

Apply the division operation,

⇒ x = 45

Therefore, she makes 45 biscuits in 30 minutes.

The area of shaded rectangle is 8/3 square units.

To find the area of shaded rectangle.

What is rectangle?

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees.

Given that:

length=4 units

width= 1-unit

The rectangle is subdivided into 3 parts parallely.so 1 units is unshaded and rest are shaded.

Area of rectangle =length*width

Area of bigger rectangle =length*width

                                       =4*1 square units

                                       =4 square units

width is subdivided into 3 parts .

so, 1/3,1/3,1/3 are the width.

Area of un shaded rectangle=length*width

                                                 =4*1/3 square units

                                                  =4/3 square units

so, Area of bigger rectangle=Area of un-shaded rectangle+ Area of shaded rectangle

4 =4/3+Area of shaded rectangle

Area of shaded rectangle=4-4/3

Area of shaded rectangle=12-4/3

Area of shaded rectangle=8/3 square units

Therefore, the area of shaded rectangle=8/3 square units.
