The number of combinations that are possible for 4 cell phone models of 6 colors with 5 calling plans is  120 .

We have to find the total number of combinations of cell phone models, colors, and calling plans,

So , we multiply the number of choices for each category.

By Using the multiplication principle of counting:

⇒ Total number of combinations = (number of phone models) × (number of colors) × (number of calling plans) ;

⇒ 4 × 6 × 5

⇒ 120

Therefore, there are 120 possible combinations of cell phone models, colors, and calling plans from this particular cell phone company.

Answer:

The height of an equilateral triangle can be found using the Pythagorean theorem by treating it as a 30-60-90 triangle. In a 30-60-90 triangle, the ratio of the side lengths is 1:√3:2. In this case, the side length of 3 cm is the shorter leg, so the height (the longer leg) is 3√3 cm. Rounding to 1 decimal place, the height is approximately 5.1 cm.

The segments' lengths and the angles' measurements are FE = 11,  CF = 10,  d = 54, and e = 126

As this is a parallelogram c = e

so 9y = 7y + 28

9y - 7y = 28

2y = 28

y = 14

So e would be 7(14) + 28

= 98 + 28

= 126.

And as d + e = 180, d = 180 - 126

d = 54

And as CF = DE

2x = x + 5

2x - x = 5

x = 5

CF = 2x

= 2(5)

= 10

And lastly CD = FE

CD = 3x - 4

CD = 3(5) - 4

= 15 - 4

= 11

FE = 11

So the answers are:

FE = 11,  CF = 10,  d = 54, and e = 126

There are 71,536,320 ways to arrange a standard deck of 52 cards so that all cards in a given suit appear contiguously.

There are 4 suits in a standard deck of 52 cards, and we need to arrange all the cards in a given suit contiguously. Once we choose a suit to be arranged in this way, we can treat it as a block of 13 cards that need to be arranged. Therefore, we have reduced the problem to arranging 4 blocks of 13 cards each, where each block represents a suit.

Within each suit, there are 13! ways to arrange the cards. However, once we arrange the cards in one suit, we fix the relative positions of the cards in the other suits. Therefore, we only need to consider the number of ways to arrange the suits themselves.

There are 4! = 24 ways to arrange the 4 suits. For each of these arrangements, there is only one way to arrange the cards within each suit contiguously. Therefore, the total number of ways to arrange the deck of cards so that all cards in a given suit appear contiguously is:

13! x 24 = 71,536,320

Step-by-step explanation:

So working from the bottom

The last line for x > 20 shows 13 because of the top graph, the last line is 13 and there is nothing below it.

Now for x > 16, we go up a line and see 14

That's where you would add 14 + any number below it

14 + 13 = 27. So for x > 16, you'd write 27

Going up, we have X > 12. Same thing, we go up a line and see 19. So now we just add 29 and any number below that

19 + 14 + 13 = 46. So for x > 12, you'd write 46.

You'll do that for the rest of the table. hope that helps

The crane's shadow is 45 meters long when the crane is 24 meters tall.

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is indicated here by the symbol "≅"

Let the shadow cast by the crane be x.

The triangle formed by the tower and by the crane are similar.

Using the rule of similar triangles we have:

16/24 = 30/x

16x = (30)(24)

x = 45

Step-by-step explanation:

an inscribed angle has its vertex on the circle, and the sides of the angle are two chords of the circle.

the inscribed angle is half the size of the arc angle (the angle at the center of the circle) of the arc that the two sides cut out of the circle.

110° is the arc angle (at the center of the circle) of the arc GJ.

for the inscribed angle GFJ the vertex is F, and the angle there is half of the arc angle :

angle GFJ = 110/2 = 55°

the second problem is the opposite "direction".

we have the inscribed angle FJH = 36°.

and we want the arc angle FH.

now, since the inscribed angle is half of the arc angle, the arc angle is twice the inscribed angle :

arc angle FH = 36×2 = 72°

The coordinates  ( 6,-8 ) are plotted by moving 6 units right and 8 units down.

The probability of a gym member attending yoga is 0.625 or 62.5%.

Probability is the likelihood or chance of an event happening. In this scenario, we have information about the number of gym members attending yoga and dance, which can be used to calculate the probability of a gym member attending yoga.

Out of the 400 gym members, 300 regularly attend yoga, and 50 attend both yoga and dance. This means that the number of gym members attending only yoga is 300-50=250. The probability of a gym member attending yoga can be calculated by dividing the number of gym members attending yoga by the total number of gym members.

Probability of a gym member attending yoga= Number of gym members attending yoga/Total number of gym members

Probability of a gym member attending yoga= 250/400

Shelly spent 40 minutes jogging and 22 minutes cycling, and burned 620 calories to write this in equation we get,

40x + 22y = 620

Shelly swapped times,

22 minutes of jogging and 40 minutes of cycling and burned the same number of calories,

22x + 40y = 620

By multiplying two equation we get,

multiply equation 1 by 22 and equation 2 by 40 we get,

880x + 484y = 13640

880x + 1600y = 24800

Now subtracting equation 1 from 2 we get,

1116y = 11160

y = 11160/1116

y = 10

Therefore, putting value of y in equation 1 we get,

880x + 484(10) = 13640

880x = 13640 - 4840

x = 8800/880

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object.

Total number of bottles = 24

Capacity of each bottle = 12 oz

Total capacity of the 24 water bottles = 12 × 24 = 288 oz

Now we have,

8 ounces = 1 cup

288 ounces = 288 / 8 = 36 cups

So there are 36 cups of water in total.

Therefore the gradient ( m ) is not given

from the question point =(-9,-3) and (-12,-4).

Gradient (m) =

therefore m = 1/3.

The equation

[tex] = \frac{y - y1}{x - x1} = m \\ \frac{y - ( - 3)}{x - ( - 9)} = \frac{1}{3} \\ \frac{y + 3}{x + 9} = \frac{1}{3} \\ 3(y + 3) = 1(x + 9) \\ 3y + 9 = x + 9 \\ 3y = x + 9 - 9 \\ 3y = x + 0 \\ 3y - x = 0[/tex]

The surface area of the triangular prism is 62 square units.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has.

The side length of each of the three squares is 4 units.

The area of each would be:

4² = 16 sq. units.  

For the three squares we have:

16(3) = 48 sq. units.

The area of each triangle is 7 sq. units.

Step-by-step explanation: A congruence statement expresses that two figures have the same size and shape. Here's how you can write a congruence statement step by step:

Write the two figures you want to compare. For example, you could write "Triangle ABC" and "Triangle DEF".

Use the symbol "≅" to indicate congruence. Place the symbol between the two figures, like this: "Triangle ABC ≅ Triangle DEF".

Label the corresponding parts of the two figures to show that they are congruent. For example, you could write "AB = DE", "BC = EF", and "AC = DF".

The final congruence statement would look like this: "Triangle ABC ≅ Triangle DEF, with AB = DE, BC = EF, and AC = DF". This statement says that Triangle ABC is congruent to Triangle DEF, and that the lengths of their corresponding sides are equal.
