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

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.

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.

4. Why did the Americans cross back over the bridge at Concord? The word metabolism comes from a Greek word that means "a change." Metabolism can be defined as the sum of the nutritional and waste processes of an organism. This involves the digestion, use, and excretion of food. Studies have shown that an animal's metabolism is affected by the climate; warm-blooded animals have slower metabolisms at warmer temperatures. This means that the animals have to eat less because their bodies do not use as much energy. During colder weather, animals tend to have faster metabolisms. Therefore, animals usually eat more during colder seasons. Do It! Metabolism generally _________ to the weather.
