Step-by-step explanation:

Debbie can make 12 bows from 2 yards of ribbon, as shown by the division equation (2 ÷ 1/6 = 12) and confirmed by the multiplication equation (12 × 1/6 = 2).

The student is asking about division and multiplication of fractions in the context of making bows from a length of ribbon. To determine how many bows Debbie can make with 2 yards of ribbon, when each bow requires 1/6 yard, we formulate a division equation and a multiplication equation.

The division equation is:

Number of bows = Total yards of ribbon ÷ Yards of ribbon per bow

Number of bows = 2 yards ÷ 1/6 yard

The multiplication equation is the inverse of the division equation, which helps us to check our work:

X bows × 1/6 yard per bow = 2 yards (X represents the number of bows)

By solving the division equation:

Number of bows = 2 yards × (6/1 bows)

Number of bows = 12 bows

So, Debbie can make 12 bows from 2 yards of ribbon. The multiplication equation confirms this since 12 bows × 1/6 yard equals 2 yards.

Answer:

B. No, because the sample was not random.

Step-by-step explanation:

The survey asks to find the favourite sport of the school's students. Not just the school's seventh graders. The seventh graders do not make up a random sample of the student body, and therefore the results of this survey are invalid.

Let's look at the answers:

A - No. We've already discussed why sampling just the seventh graders is wrong.

B - Yes. The entire seventh grade is not a random sample of the entire school and do not yield a valid response.

C - No. The school surveyed every seventh grader, not every seventh student. This is a play on words.

D - No. Every student in the seventh grade was sampled, not just girls.

Answer:

A. 20

Step-by-step explanation:

[tex]a^{2} + b^{2} = c^{2}[/tex]

Plug in the numbers

[tex]15^{2} + b^{2} = 25^{2}[/tex]

Simplify the equation

225 + b = 625

Subtract both sides by 225

625 - 225 = 400

Your equation should look like

b = 400

Because you squared it, now you have to get it back to the formula you started with first. To do this, just find the square root.

The square root of 400 is 20

[tex]15^{2}+ 20^{2} =25^{2}[/tex]

Answer:

D. q minus 22 = 24: Add 22 to both sides. The answer is 46.

Step-by-step explanation:

From the list of options, one would notice that the number is represented with letter q.

So, we'll analyse the question base on the assumption that the number is represented with letter q.

The statement "Twenty-two less than a number is twenty-four".

First, this statement can be splitted into two.

"Twenty-two less than a number" and "is twenty-four."

Taking them one after the other.

"Twenty-two less than a number" as it is means; q - 22

Then we have "is twenty-four."

is represents =

twenty-four = 24

This gives "= 24"

Bringing the two expressions together;

q - 22 = 24

To get the value of q; simply add 22 to both sides

q - 22 + 22 = 24 + 22

q = 46

Hence, option D is correct.

Step-by-step explanation:

To find the radius of the sphere formed by melting five metal cubes with 7 cm sides, calculate the combined volume of the cubes and equate it to the volume of the sphere; then solve for the radius, which is approximately 7.24 cm.

To find the radius of the sphere formed by melting five metal cubes, we need to equate the total volume of the cubes to the volume of the sphere. The volume of a cube with a side length of 7 cm is found by the formula V = s³, where s is the side length of the cube. For one cube, this is V = 7 cm x 7 cm x 7 cm = 343 cm³. Since there are five cubes, the total volume is 5 x 343 cm³ = 1715 cm³.

The volume of a sphere is given by the formula V = 4/3 * π * r³, where r is the radius of the sphere. We must solve for r when the volume is 1715 cm³. Setting the volumes equal gives 4/3 * π * r³ = 1715 cm³. Solving for r yields:

r³ = (1715 cm³) / (4/3 * π)

r = (1715 cm³) / (4.14159)^√(1/3)

r ≈ 7.24 cm

Therefore, the radius of the sphere is approximately 7.24 cm.

x = 2   or  x = 4

Step-by-step explanation:

Solve:   2 log x = log 2 + log(3x - 4)

log (x^2) =  log 2 + log (3x - 4)

log (x^2) = log [2*(3x - 4)]

x^2 =  2*(3x - 4)

x^2 = 6x - 8

x^2 - 6x + 8 = 0

factor:

(x - 2 )(x - 4) = 0

x = 2   or  x = 4

Step-by-step explanation:

Unless you see a bar over one or more of the numbers (specifically 9 or 39), then it is not a repeating decimal, but rather a terminated decimal.

If there is a bar over the number, it means that specific set of numbers are repeated. Another way to tell if it is repeated is if there are dots at the end.

Answer:

4y - 7

Step-by-step explanation:

Like terms are terms that have the same variable part. Variable part means the part of a term that is one or more variables and the exponents of the variables.

For example, in 2x^2 + 4xy + 5x^2 + 2y + 5 - 3y, the terms 2x^2 and 5x^2 have x^2 as their variable part. They are like terms. Likewise, 2y and -3y have y as their variable part. They are like terms. 2x^2 and 5x^2 can be combined into 7x^2. 2y and -3y can be combined into -y. The terms 4xy and 5 are not like terms and cannot be combined. By combining like terms in 2x^2 + 4xy + 5x^2 + 2y + 5 - 3y, you end up with 7x^2 + 4xy - y + 5.

Now we deal with your problem.

-4y - 4 + (-3)

The term -4y has a y as a variable. There is no other term with a y in it, so the term -4y cannot be combined.

The terms -4 and -3 have no variables. These two terms are like terms and can be combined.

-4y - 4 + (-3) =

-4y - 7

The probability for the sum of two dice to be 9 is 1/9, and the probability for rolling doubles is 1/6. These two events are mutually exclusive; hence their combined probability is the sum of the individual probabilities, which is 5/18.

The probability that the sum of two rolled dice is 9 can be calculated by identifying all possible combinations that result in a sum of 9. There are four such combinations: (3,6), (4,5), (5,4), (6,3). The probability of any one specific outcome when rolling two dice is 1/36, thus the probability of the sum being 9 is 4/36 or simplified, 1/9.

To find the probability of rolling doubles, we identify all the combinations where both dice show the same number. There are six possibilities: (1,1), (2,2), (3,3), (4,4), (5,5), (6,6), so the probability of rolling doubles is 6/36 or simplified, 1/6. These two events are mutually exclusive; thus, the total probability is found by adding the two probabilities: 1/9 + 1/6 = 2/18 + 3/18 = 5/18.

Final answer:

To solve for angle B in triangle ABC, you can use the Law of Cosines. Rearrange the equation to isolate the cosine of angle B and then take the inverse cosine to find the value of angle B. The value of angle B is approximately 99.99 degrees.

Explanation:

To solve for angle B in triangle ABC, you can use the Law of Cosines. The Law of Cosines states that the square of one side of a triangle is equal to the sum of the squares of the other two sides minus twice the product of the other two sides and the cosine of the angle between them.

In this case, you are given the lengths of sides AB, BC, and AC as 4.1 cm, 2.7 cm, and 4.5 cm respectively. You are also given the equation 4.1 = 4.5 + 2.7 - 24.3cos B. To solve for angle B, you can rearrange the equation to isolate the cosine of angle B and then take the inverse cosine to find the value of angle B.

Let's go step-by-step:

Start with the equation 4.1 = 4.5 + 2.7 - 24.3cos B

Subtract 4.5 and 2.7 from both sides: 4.1 - 4.5 - 2.7 = -3.1 - 24.3cos B

Combine like terms: -3.1 - 24.3cos B = -7.1

Add 7.1 to both sides: -3.1 - 24.3cos B + 7.1 = -7.1 + 7.1

Simplify: -3.1 + 7.1 - 24.3cos B = 0

Subtract -3.1 + 7.1 from both sides: -3.1 + 7.1 - 3.1 + 7.1 - 24.3cos B = -3.1 + 7.1

Simplify: -24.3cos B = 4.0

Divide both sides by -24.3 to isolate cos B: (-24.3cos B) / -24.3 = 4.0 / -24.3

Simplify: cos B = -0.1645

Take the inverse cosine of -0.1645 to find the value of angle B: B = cos-1(-0.1645)

Using a calculator, you can find that angle B is approximately 99.99 degrees.

Answer:

A company wants to select 3 new employees.

We have 8 candidates, 6 males, and 2 females.

1) What is the number of combinations in which the new employees can be selected?

We have 3 positions.

For the first position, we have 8 options.

For the second position, we have 7 options, because we already selected one.

For the third position, we have 6 options, because we already selected two.

The number of different combinations is (8*7*6)/(3*2*1) = 56

The division by 3*2*1 is because if we no divide by this, we are counting multiple times the same combination of employees, but they are contracted in different orders.

2) How many ways you can select only one male?

In this case, we have 3 positions, two of those positions must be for the 2 women, so in the other position, we can select only one male.

We have 6 different males for that position, so we have only 6 combinations in this case.

3) In how many ways we can select at least one male?

Previously found that we have 56 combinations in total.

We only have 2 women and 3 positions, so in all of these combinations, we have at least one male. So there are 56 combinations with at least one male.

The number of combinations in which these 3 new employees can be selected is equal to 56.

Given the following data:

Since the company needs 3 employees, it simply means there are 3 vacant positions. Thus, the number of combinations in which these 3 new employees can be selected is given by:

_nC_r = \frac{n!}{r!(n-r)!}

Combination(n, k) = n!/(r!(n - r)!)

Combination(8, 3) = 8!/(3!(8 - 3)!)

Combination(8, 3) = 8!/(3!(5)!)

Combination = (8 × 7 × 6)/(3 × 2 × 1)

Combination = 336/6

Combination = 56.

Two (2) of the 3 vacant positions must be taken by 2 women, so we can only select one male. Thus, the number of ways is given by:

Number of ways = 6 × 1

Number of ways = 6.

Choosing 1 male = 6 ways

Choosing 2 males = two males from 6 males and 1 male from two females.

Comb(6, 2) × 2 = 6!/(2!(6 - 2)!) × 2

Comb(6, 2) × 2 = 6!/(2!(4)!) × 2

Comb(6, 2) × 2 = 15 × 2

Comb(6, 2) × 2 = 30 males.

Choosing 3 males = three males from 6 males;

Comb(6, 3) = 6!/(3!(6 - 3)!)

Comb(6, 3) = 6!/(3!(3)!)

Comb(6, 3) = 20 males.

Total combination = 6 + 30 + 20

Total combination = 56.

Step-by-step explanation:

The 2 cylinders described are identical. The diameter = 2 times the radius, so the radius of the first cylinder = 1/2 * 7 = 3.5 in,  which is the same as the radius of the second one. Also the heights are the same so the volumes are the same too.
