There are 15 cats ready for new homes at the pet store. There are 5 cages with cats in the store. If each cage has the same number of cats, how many cats are in each cage?

Answer:

Percentage decrease ( from $4.09 to $3.59) is 0.1% ( Rounded to nearest tenth)

Percentage increase (from $3.59 to 4.09) is 0.1% ( Rounded to nearest tenth)

Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.

Step-by-step explanation:

$4.09 has been changed to $3.59.

Percent change = [(Value after  - Value before) / Value before]*100

                          =[tex]\frac{3.59-4.09}{4.09}*100[/tex]%

                          =[tex]\frac{-0.5}{4.09}*100[/tex]%

                          =[tex]-0.122249[/tex]%

                           =[tex]-0.1[/tex]% ( Rounded to nearest tenth)

Percentage decrease is 0.1% ( Rounded to nearest tenth)

Now lets calculate the percentage change from $3.59 to $4.09.

Percent change = [(Value after  - Value before) / Value before]*100

                          =[tex]\frac{4.09-3.59}{3.59}*100[/tex]%

                          =[tex]\frac{0.5}{3.59}*100[/tex]%

                          =[tex]0.13927[/tex]%

                           =[tex]0.1[/tex]% ( Rounded to nearest tenth)

Percentage increase is 0.1% ( Rounded to nearest tenth)

Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.

This mathematical problem involves calculating percentages of increase and decrease, using the same technique to calculate both. The percentage decrease when the price was marked down from $4.09 to $3.59 is approximately 12.2%, while the percentage increase from $3.59 back to $4.09 is approximately 13.9%, making the percentages of change different for the two price shifts. The greatest change occurs with the increase back to the original price.

The subject of this question is mathematics, specifically the calculation of percentage increases and decreases. To find the percentage decrease when the price was marked down from $4.09 to $3.59, we use the formula:

[(Old Price - New Price) / Old Price] x 100

[(4.09 - 3.59) / 4.09] x 100 ~ 12.2%

So the percentage decrease is around 12.2%. Now, to calculate the percentage increase from $3.59 back to $4.09, we use the same approach:

[(4.09 - 3.59) / 3.59] x 100 ~ 13.9%

This gives us a percentage increase of approximately 13.9%. Therefore, the percentage of change is not the same for both price changes. The greater change is seen with the increase back to the original price, which results in a larger percentage of 13.9% compared to the decrease of 12.2%.

Let the weight of triangle be x units. You are given that the weight of square is 1 unit.

1) On the left side of the balanced beam you can see 3 triangles and 5 squares. The weight on left side is 3·x+5·1=3x+5 units.

2) On the right side of the balanced beam you can see 2 triangles and 7 squares. The weight on right side is 2·x+7·1=2x+7 units.

3) If the whole system is balanced, then the weights on left and right sides are equal:

3x+5=2x+7.

Solve this equation:

3x-2x=7-5,

x=2 units.

Answer: option A

Consider the given equation [tex]x^2-8x+14=0[/tex]

We will solve this equation by completing the square method.

Consider the coefficient of 'x', divide it by '2'. then adding and subtracting the square of this number in the given equation.

Coefficient of 'x' = -8

By dividing it by '2', we get -4

Taking the square of '-4' = 16

Adding and subtracting '16' from the given equation.

[tex]x^2-8x+14+16-16=0[/tex]

So, [tex]x^2-8x+16 = -14+16[/tex]

This equation shows one of the step used in solving the equation by completing the square method.

Therefore, option 1 is the correct answer.

For Jamal to solve the equation, [tex]x^2 - 8x + 14 = 0[/tex], by completing the square, one of the steps that could be taken is: A. [tex]\mathbf{x^2 - 8x + 16 = - 14 + 16}[/tex]

Jamal was given the equation, [tex]x^2 - 8x + 14 = 0[/tex], to solve by completing the square.

To do this, the first step would be to move the constant, 14 to the other side of the equation by subtracting 14 from both sides of the equation.

[tex]x^2 - 8x + 14 - 14 = 0 -14\\\\x^2 - 8x = -14[/tex]

The next step to take is for Jamal to add the square of half of the coefficient of x to both sides of the equation.

[tex]x^2 - 8x + 16 = - 14 + 16[/tex] (this tallies with the first option given).

Therefore, for Jamal to solve the equation, [tex]x^2 - 8x + 14 = 0[/tex], by completing the square, one of the steps that could be taken is: A. [tex]\mathbf{x^2 - 8x + 16 = - 14 + 16}[/tex]

The slope of the Line is 3

What is the slope of a line?

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) may be easily determined by finding the difference among the coordinates of the points. The slope is normally represented by the letter 'm'.

Conclusion: The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

The general equation of a line having a slope is y = mx + c

we have to arrange the equation 6x - 2y = 10 in y = mx + c form

6x -2y = 10

2y = 6x - 10

y = 3x - 5

The slope of the line is represented by m, the value of m in equation y = 3x - 5 is 3

The correct product of 27 and 600 is:

[tex]\[ \boxed{16200} \][/tex]

"The correct answer to find the product of 27 and 600 is not obtained by simply adding 27 six times and then appending zeros. The correct method to calculate 27 x 600 is as follows:

 First, multiply 27 by 6 to get the hundreds place value correct:

[tex]\[ 27 \times 6 = 162 \][/tex]

Next, since we are multiplying by 600, we need to account for the additional zeros. Each zero represents a factor of 10, so we multiply 162 by 100 (since there are two zeros in 600):

[tex]\[ 162 \times 100 = 16200 \][/tex]

Therefore, the correct product of 27 and 600 is:

[tex]\[ \boxed{16200} \][/tex]

The method described in the question is incorrect because it does not properly account for the place value of the digits in the multiplication. When multiplying by a number with zeros, each zero represents a power of ten and must be considered in the multiplication process. The correct method involves multiplying the numbers and then adjusting the final product's place value by adding zeros according to the multiplier's zeros."

Answer:

you minus 8 from 20 which will = to 12. Then you divide 12 by 4.99 and it equals to like 2.4 but you can't buy a .4 of a candy bar so have to round it down to 2

Step-by-step explanation:

Janelle can buy 2 snacks with her remaining budget after purchasing a movie ticket. The inequality 20 ">= 8" + 4.99x is satisfied with x=2, where each snack costs $4.99.

Janelle is at the movie theater with a budget of $20 to spend. After purchasing her movie ticket for $8, she wants to buy snacks with the remaining money. Since each snack costs $4.99, we can represent the situation with the following inequality:

20 ≥ 8 + 4.99x

To find out how many snacks, x, Janelle can buy, we subtract the cost of the movie ticket from her total budget:

$20 - $8 = $12

Now, we divide the remaining amount by the cost of one snack:

$12 / $4.99 ≈ 2.4

Since Janelle cannot buy a fraction of a snack, we round down to the nearest whole number. Thus, Janelle can buy 2 snacks with her remaining budget.

To find segment AD given HD = 24 when H is the centroid, you would use the property of the centroid that divides medians in a 2:1 ratio. Since HD is the shorter part, multiply 24 by 2 to get AD = 48 units.

You're asking how to find the length of segment AD given HD = 24 in a geometric context involving a centroid. To find AD, we must understand the properties of the centroid, which is the point where the three medians of a triangle intersect. A median connects a vertex of a triangle to the midpoint of the opposite side, and in every triangle, the centroid divides each median in a 2:1 ratio, with the longer segment being closest to the vertex.

Given that HD = 24 and D is the midpoint of AH (because H is the centroid), according to the centroid properties, the length of AD must be twice the length of HD. Therefore:

AD = 2 * HD

AD = 2 * 24

AD = 48

The length of segment AD is 48 units.

There can be 24 unique four-digit numbers formed from the numerals 7, 6, 5, and 3, calculated by the factorial of 4 (4!).

The student asks how many four-digit numbers can be made from the numerals 7, 6, 5, and 3. These numbers can be arranged in a systematic way, and the total number of combinations can be calculated using permutations. The formula to calculate permutations without repetition is n! (n-factorial), where 'n' is the number of numerals to arrange.

In this case, we have 4 numerals, so the calculation would be 4! This equals to 4 × 3 × 2 × 1 = 24. Thus, there are 24 unique combinations when we arrange the numerals 7, 6, 5, and 3 into four-digit numbers without any repetitions.

The probability that at least one of the three randomly selected internet users is more careful about personal information when using a public wi-fi hotspot is 97.3%.

To find the probability that at least one of the three randomly selected internet users is more careful about personal information when using a public wi-fi hotspot, we can calculate the probability of the complement event, which is the event that none of the users are more careful. Since the probability that an internet user is more careful is 70%, the probability that a user is not more careful is 1 - 70% = 30%. The probability of the complement event for all three users is (0.3)^3 = 0.027. Therefore, the probability that at least one user is more careful is 1 - 0.027 = 0.973, or 97.3%.

Additional information that the survey subjects volunteered to respond does not affect the calculation of the probability. The probability is based solely on the given percentage from the poll, which represents the proportion of internet users who are more careful about personal information when using a public wi-fi hotspot.

The probability that at least one internet user is more careful about personal information when using a public wi-fi hotspot is 0.973.

To find the probability that at least one person is more careful about personal information when using a public​ wi-fi hotspot, we can use the complement rule. The complement of at least one person being more careful is that no one is more careful. So, the probability that no one is more careful is 0.3 multiplied by 0.3 multiplied by 0.3 (since there are three internet users). Then we subtract this probability from 1 to find the probability that at least one person is more careful. So, the probability that at least one person is more careful is 1 - (0.3 x 0.3 x 0.3) = 0.973.

The additional information that the survey subjects volunteered to respond does not affect the result of the probability calculation. The probabilities are based on the initial survey results, and any additional information would be separate from those probabilities.
