manda swims 40 meters per minute. She uses the inequality below to calculate how many minutes, m, it takes her to swim at least 1,500 meters.
40m≥1,500
Which set of numbers makes the inequality true?

A. {24,25,37.5}
B. {25,28.5,37}
C. {37,39,40.5}
D. {37.5,42,43.5}

Answer:

12.5

Step-by-step explanation:

[tex]1.7x \times 2x - 4y \times 3x \\ 7x \times 3x - 4y \times 2y \\ 21x ^{2} - {8}y^{2} \\ 2.3x \times 2x - 4y \times 3y \\ 6x ^{2} - {12y}^{2} \\ 3.4x \times 5x - 5x \times 4x \\ {20x}^{2} - {20x }^{2} \\ 0 [/tex]

Answer:

$11.75

Step-by-step explanation:

To find a unit price you must divide the price by how many objects bought.

So I divided 82.25 by 7

When I did this I got 11.75

This means each scarf costs $11.75

B. 7

Step-by-step explanation:

a) The volume of the base of the crystal is 240 inches³

b) The space contained by the vase of the crystal is 24 inches³

A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges

The volume of a cuboid is the product of its length , width and height

The volume of the cuboid is given by

Volume of Cuboid = Length x Width x Height

Given data ,

(a) Since the cross sections are always cuboids that are 5 inches wide by 4 inches long, the area of each cross section is 5 x 4 = 20 square inches. Since the vase has a height of 12 inches, the volume of the vase is equal to the product of the area of the base and the height, which is 20 x 12 = 240 cubic inches.

(b) If the crystal is half an inch thick on each of the sides and on the bottom, then the dimensions of each cross section are 5 inches by 4 inches by 1 inch (since each side of the crystal adds half an inch to the length and width of the rectangle). The volume of each cross section is therefore 5 x 4 x 1 = 20 cubic inches.

However, since the crystal takes up half an inch on each side, the actual space contained within the vase is reduced by 2 x (5 + 4 + 0.5 + 0.5) x 12 = 216 cubic inches (where 5 + 4 is the sum of the lengths and widths of the rectangle, and 0.5 + 0.5 is the thickness of the crystal on each side).

Hence , the approximate space contained within the vase is 240 - 216 = 24 cubic inches

Answer: 167.55 units cubed

Step-by-step explanation:

To find this, you must know the formula for a cone. The area is A=πr(r+h2+r2). We can get that the A=π4(4+102+(4)2). We got this from plugging in the numbers. The radius is equal to half the diameter, so the radius is 4. The answer is 167.55 units cubed.

The statement is false and same mean can have different variability

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the mean of the data be represented as M

Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.

For example, consider the following two sets of data:

Set 1: 1, 2, 3, 4, 5 (mean = 3)

Set 2: 0, 2, 3, 4, 6 (mean = 3)

Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.

Hence , two sets of data with the same mean can have different variability,

Antonio can score in his next game a score of 111 to reach his goal.

Arithmetic operations are the basic part of mathematics which combines the basic operations like addition, subtraction, multiplication and division.

Given that,

Antonio is in a bowling league. His goal is to score an average of at least 100 points per game.

Total number of games = 6

If each game score is at least 100, total number of scores must be at least 6 × 100 = 600

Scores got so far = 105 + 95 + 97 + 82 + 110

                             = 489

Score needed for the next game = 600 - 489 = 111

Hence the score needed in the next game is 111.
