The river often referred to as the "Father of Ocean" is the Amazon River.

It is the largest river by discharge volume of water in the world and is responsible for about 20% of the Earth's freshwater discharge into the Atlantic Ocean.

The immense volume of water it carries into the ocean earns it the nickname "The River Sea."

Explanation

Let's decode the numbers based on the given equivalences:

1 = 9

2 = 8

3 = 7

4 = 6

5 = 10

For 9245:

9 (from 1)

2 (from 9)

4 (from 6)

5 (from 10)

So, 9245 translates to 9285.

Among the options provided, the correct one is: D) 10898

Explanation

To find 1.03^10 rounded to two decimal places:

1.03^10 ≈ 1.34408708

1.03^10 ≈ 1.34408708

Rounded to two decimal places, it becomes 1.34.

Explanation

Caries, commonly known as tooth decay, is a dental condition characterized by the demineralization of tooth enamel, leading to the formation of cavities or holes in the teeth.

This disease is primarily caused by the action of bacteria in the mouth, which produce acids that erode the enamel when carbohydrates are consumed.

If left untreated, caries can progress deeper into the tooth, causing pain, infection, and eventual tooth loss.

Prevention through good oral hygiene practices, regular dental check-ups, and a healthy diet low in sugary and acidic foods is key to avoiding this common dental problem.

Explanation

To find the area of a section with a central angle of 60° and a radius of 4.2 cm, we can use the formula for the area of a sector of a circle:

Area of sector = (θ/360) * π * r^2

Where:

θ is the central angle in degrees

π is approximately 22/7

r is the radius of the circle

Given:

θ = 60°

π ≈ 22/7

r = 4.2 cm

Substituting the values into the formula:

Area of sector = (60/360) * (22/7) * (4.2)^2

= (1/6) * (22/7) * 17.64

≈ (1/6) * 22 * 2.52

≈ (11/3) * 2.52

≈ 9.24 cm²

Therefore, the area of the sector is approximately 9.24 square centimeters.
