Answer:

1. 48x + 24= 24(2x + 1)

2. 18n + 36= 18(n + 2)

3. 15 + 12k= 3(5+4k)

Step-by-step explanation:

1. What factor both goes into 24 and 48? 24 does!

so, 48x + 24= 24(2x + 1).

2. What factor both goes into 18 and 36? 18 does!

so, 18n + 36= 18(n + 2).

3. What factor both goes into 15 and 12? 3 does!

so, 15 + 12k= 3(5+4k).

Final answer:

The distributive property allows us to create equivalent expressions by factoring out a common factor from each term, resulting in expressions like 24(2x + 1), 18(n + 2), and 3(5 + 4k) for 48x + 24, 18n + 36, and 15 + 12k respectively.

Explanation:

To use the distributive property to write equivalent expressions for each of the following:

48x + 24: Both terms are divisible by 24. Therefore, the equivalent expression using the distributive property is 24(2x + 1).

18n + 36: Both terms are divisible by 18. Therefore, the equivalent expression using the distributive property is 18(n + 2).

15 + 12k: Both terms are divisible by 3. Therefore, the equivalent expression using the distributive property is 3(5 + 4k).

In each case, identifying the common factor and using it to factor out the original expression creates an equivalent expression where the terms inside the parenthesis are the results of dividing the original terms by the common factor.

31. the minimum perimeter of the rectangle is ( 38 ) inches.

32.the maximum perimeter is ( 170 ) inches.

To find the minimum and maximum perimeter of the rectangle, we need to consider all possible combinations of length and width that yield an area of 84 square inches.

Given that the area of the rectangle is 84 square inches, we can find all the pairs of factors of 84. These pairs will represent the possible combinations of length and width.

The pairs of factors of 84 are:

1. [tex]\( 1 \times 84 \)[/tex]

2. [tex]\( 2 \times 42 \)[/tex]

3. [tex]\( 3 \times 28 \)[/tex]

4. [tex]\( 4 \times 21 \)[/tex]

5. [tex]\( 6 \times 14 \)[/tex]

6. [tex]\( 7 \times 12 \)[/tex]

Now, we calculate the perimeter for each pair:

1. [tex]\( \text{Perimeter} = 2 \times (1 + 84) = 2 \times 85 = 170 \)[/tex]

2. [tex]\( \text{Perimeter} = 2 \times (2 + 42) = 2 \times 44 = 88 \)[/tex]

3. [tex]\( \text{Perimeter} = 2 \times (3 + 28) = 2 \times 31 = 62 \)[/tex]

4.[tex]\( \text{Perimeter} = 2 \times (4 + 21) = 2 \times 25 = 50 \)[/tex]

5.[tex]\( \text{Perimeter} = 2 \times (6 + 14) = 2 \times 20 = 40 \)[/tex]

6.[tex]\( \text{Perimeter} = 2 \times (7 + 12) = 2 \times 19 = 38 \)[/tex]

Therefore, the minimum perimeter of the rectangle is ( 38 ) inches, and the maximum perimeter is ( 170 ) inches.

use the formula for hypotenouse of a triangle to find the diangles as if they were the hypotenouse so 5 squared plus 10 squared is 25 plus 100 which is 125 which has the square root 11.2. so now you have the length (longer side) so for the width it's 1 squared plus 2 squared which is 1 plus 4 is 5 so the square root of 5 is about 2.2 so that's the width (shorter side) so now for the area it's 11.2 (length) times 2.2 (width) which is about 25. hope this hopes let me know if you have a question

Answer:

1. 21 represents the cost of manufacturing one handband.

3. The initial start up cost is $15000.

5. The company spends $57000 to manufacture 2000 handbands.

Step-by-step explanation:

We are given the cost function for manufacturing 'h' amount of handbands and it is provided that there was initial start up costs involved.

Now, as the cost function is given by, C(h) = 21h + 15000.

We can see that the initial start up cost is $15000.

As, 'h' is the number of handbands being made. So, 21h in C(h) is the cost of manufacturing 'h' handbands.

Therefore, 21 is the cost of manufacturing one handband.

Since, C(h) = 21h + 15000.

Substituting h = 2000, we get,

C(2000) = 21×2000 + 15000.

i.e. C(2000) = 42000 + 15000.

i.e. C(2000) = 57000.

The company spends $57000 to manufacture 2000 handbands.

Since, we are provided with only cost function, we can not talk about the profit.

Hence, option 1, 3 and 5 are correct.

PLEASE MARK ME BRAINLIST!

Answer:

1. 21 represents the cost of manufacturing one handband.

3. The initial start up cost is $15000.

5. The company spends $57000 to manufacture 2000 handbands.

Answer:

I keep getting 141.421... so rounded it would be 141.4

Step-by-step explanation:

The length of the interior diagonal of the box is approximately 141.4 cm.

Suppose the base of the prism has length = l units, and width = w units.

Suppose that the height of the prism is of h units, then:

[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]

is the volume of that prism.

The base is a rectangle with length = L units, and width = W units, so its area is:

[tex]b = l \times w\: \rm unit^2[/tex]

We are given that;

Height= 100cm

Width=80cm

Length=60cm

Now,

Using the Pythagorean theorem, we can find the length of the interior diagonal as:

diagonal = sqrt(l^2 + w^2 + h^2)

diagonal = sqrt(100^2 + 80^2 + 60^2)

diagonal = sqrt(10000 + 6400 + 3600)

diagonal = sqrt(20000)

diagonal ≈ 141.4

Therefore, the length of the diagonal of prism will be 141.4

Answer:

im pretty sure its median

Step-by-step explanation:

Mean and median can be used to describe two data sets that are both symmetric.

An observation that differs abnormally from other values in a population-based random sample is referred to as an outlier. In a way, this definition defers to the analyst's (or a consensus process') judgement as to what constitutes aberrant behaviour.

Given:

Two symmetric data sets are described by the following measure of centre:

The mean and median are two numerical measures of centre that, if the distribution is symmetric, can determine the centre as the average value; otherwise, the median can be employed because it is not robust against outliers.

For example : Height of 3 students in 70, 72, 74

Mean of students= (70 +72+ 74)/ 3 = 72

and, median = 72

Hence, mean and median can be used.

Segment JK is congruent to segment DE because they have the same length.

To determine if segment JK is congruent to segment DE, we need to compare their lengths. We can use the distance formula to find the length of each segment.

For segment JK, the coordinates are J(1, 4) and K(-6, -8). Using the distance formula, we have:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
  = sqrt((-6 - 1)^2 + (-8 - 4)^2)
  = sqrt((-7)^2 + (-12)^2)
  = sqrt(49 + 144)
  = sqrt(193)

For segment DE, the coordinates are D(3, 3) and E(-4, -9). Using the distance formula, we have:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
  = sqrt((-4 - 3)^2 + (-9 - 3)^2)
  = sqrt((-7)^2 + (-12)^2)
  = sqrt(49 + 144)
  = sqrt(193)

Since the lengths of segment JK and segment DE are both sqrt(193), they are congruent.

Step-by-step explanation:

The probability of guessing a 3-digit combination correctly, with no repetition, is 1 out of 720 option C.

To calculate the probability of getting a 3-digit combination correct where no digits can be repeated, you can use the concept of permutations.

For the first digit, you have 10 options (0 through 9). For the second digit, since no digit can be repeated, you have 9 options left. For the third digit, you have 8 options left.

So the total number of possible combinations is [tex]\(10 \times 9 \times 8 = 720\).[/tex]

Therefore, the probability of getting the correct combination is:

[tex]\[\frac{1}{720}\][/tex]

So, the correct answer is option C) 1/720.

To find the total views a music video got over the first 5 days with a 20% daily increase, calculate the views for each day using a geometric sequence formula and sum them, resulting in approximately 13023 views.

To calculate the total views a music video got over the course of the first 5 days with a 20% daily increase starting at 1750 views, we use the geometric sequence formula V = V0 × (1 + r)n, where V0 is the initial number of views (1750), r is the daily increase rate (0.20), and n is the day number. The total views (TV) over 5 days is calculated by summing the individual daily views.

Day 1: 1750 views

Day 2: 1750 × (1 + 0.20) = 2100 views

Day 3: 1750 × (1 + 0.20)2 = 2520 views

Day 4: 1750 × (1 + 0.20)3 = 3024 views

Day 5: 1750 × (1 + 0.20)4 = 3628.8 views, rounded to 3629 views

The total views over the five days is the sum of daily views: 1750 + 2100 + 2520 + 3024 + 3629 = 13023 views.

All the segments that are parallel to GH in the given shape are, BC, AD and FI. Option A

How to identify all segments parallel to GH

To identify all segments parallel to GH, understand the basic structure of a cuboid and its faces.

A cuboid is a three-dimensional shape with six rectangular faces. Each face of the cuboid is parallel to the opposite face. This property allows us to identify segments that are parallel to each other within the cuboid.

To identify segments parallel to a specific segment in a cuboid, follow these steps:

Understand the orientation of the cuboid:

Visualize the cuboid and identify its three pairs of opposite faces. These faces are parallel to each other.

Identify the given segment:

Determine the specific segment in the cuboid to which you want to find parallel segments.

In this case GH

Locate the faces that contain the given segment:

Identify the faces that contain the given segment. These faces will be parallel to each other.

Based on the highlighted steps above, by visualization,

Segment BC is parallel to GH

Segment AD is parallel to GH

Segment FI is parallel to GH

Therefore, all the segments that are parallel to GH are, BC, AD and FI. Option A

The point-slope equation for the line passing through (-2, -20) and (9, 79), is y = 9x - 2.

To find the point-slope equation for the line that passes through the points (-2, -20) and (9, 79), we first need to calculate the slope (m). The formula for the slope is given by:

m = (Y2 - Y1) / (X2 - X1)

Using the given points, we get:

m = (79 - (-20)) / (9 - (-2)) = 99 / 11 = 9

Now, using the point-slope form of the equation y - y1 = m(x - x1), and the first point (-2, -20), we have:

y - (-20) = 9(x - (-2))

Simplifying this, we get:

y + 20 = 9(x + 2)

Or

y = 9x + 18 - 20

y = 9x - 2

This is the point-slope equation for the line that passes through the points.
