The area of Russia is about 1.71 x 107 square kilometers. The area of Jamaica is about 1.10 x 104 square miles. How many times larger is Russia than Jamaica? Write your answer in scientific notation, and round the decimal part of your answer to two decimal places.

Answer:

B, 3/4

Step-by-step explanation:

you can divide the top and bottom by 6

6 * 3 = 18

6 * 4 = 24

so it applies the same for dividing

18/6 = 3

24/6 = 4

If you have trouble dividing by larger numbers, try dividing by two if both the numerator and denominator are even numbers (in this case they are)

Your answer is 3/4

hope this helps :)

Answer:

5/6

Step-by-step explanation:

Find the individual square root of the numerator and denominator which is 5 and 6=5/6

The simplified radical of (√25/36) is 5/6.

The term "radical" is used to represent the square root or nth roots. Expression with a square root is referred to as a radical expression. Radicand: A value or phrase included within the radical symbol.

We have,

Expression: (√25/36).

Now, factorizing the numerator and denominator separately

25 = 5 x 5

36 = 6 x 6

So, (√25/36)

= (√(5x 5)/(6 x 6))

= 5/6

Answer:

C. Median

Step-by-step explanation:

If both sides are symmetrical, then there is no need to try and find the mean or anything because you already have the middle point and no outliers. If there were outliers it'd be different, unless the outliers were symmetrical with the rest of it, then the median would still be a good option.

Answer:

139

Step-by-step explanation:

Just took the quiz on K-12

Hope its not to late

The prediction for the number of passwords in which the first character is a number is 139. Therefore, option B is the correct answer.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

The answer is 192 passwords. This is because there is an equal probability of each character (0-9 and uppercase letters) being chosen as the first character of a password.

Since there are 10 different numbers (0-9) and 26 uppercase letters, the probability of the first character being a number is 10/36

If 500 passwords are generated, the expected number of passwords in which the first character is a number is 500 ×10/36

= 5000/36

= 138.88

≈ 139

Therefore, option B is the correct answer.

Divide the hexagon in identical triangles.

Triangle area = length × width / 2

6 × 6 = 36

36/2= 18

The area of a regular hexagon is 85.28 square inches.

Given that, Lin and Andre used different methods to find the area of a regular hexagon with 6-inch sides.

We need to find the area of a hexagon using both methods.

The formula for the area of a regular hexagon is (3√3 s²)/2, where 's' is the length of the side of the hexagon. Since we are talking about a regular hexagon, it should be noted that all sides are of equal length. When one side of the regular hexagon is known, the area can be calculated with the formula, Area of the hexagon = (3√3 s²)/2, where 's' is the length of the side of the hexagon.

We know that, the area of an equilateral triangle=√3/2 × a².

So, the area of an equilateral triangle= √3/2 × 6²

=18√3 square inches

Now, the area of a hexagon=6×18√3

=108√3=187.06 square inches

Area of the rectangle = length × width = 10.4 × 6 = 62.4 square inches

Area of a triangle= 1/2 × Base × Height = 1/2 × 10.4 × 2.2 = 11.44 square inches

Now, 11.44 × 2=22.88

Area of a regular hexagon =  62.4+22.88 =85.28 square inches

Therefore, the area of a regular hexagon is 85.28 square inches.
