Answer:

Step-by-step explanation:

Let x be the adult weight of a puppy A

25% of x = 8 pounds

[tex]\frac{25}{100}*x=8\\\\ x=\frac{8*100}{25}\\\\ =8*4=32pounds\\[/tex]

Final answer:

To calculate the adult weight of Puppy A, divide the current weight of 8 pounds by 0.25 since 8 pounds is 25% of the adult weight. The adult weight of Puppy A is 32 pounds.

Explanation:

The student is asking how to find the adult weight of Puppy A, given that its current weight is 25% of its adult weight. To solve this, we need to use the concept of percentages. If Puppy A currently weighs 8 pounds and this represents 25% of the adult weight, we can set up a proportion:

25% (current weight) / 100% (adult weight) = 8 pounds / adult weight

To find the adult weight, we divide 8 pounds by 25% (0.25 in decimal form):

Adult weight = 8 pounds / 0.25

Adult weight = 32 pounds

Therefore, the adult weight of Puppy A is expected to be 32 pounds.

Step-by-step explanation:

To make an educated decision between the two job offers, you need to consider factors such as the number of hours worked, additional benefits, potential for overtime, job satisfaction, career growth opportunities, and work-life balance.

To make an educated decision, there are a few factors to consider when comparing these two job offers. First, you need to know the number of hours you will be working in a year for both jobs. Second, you need to know if there are any additional benefits, such as health insurance or retirement plans, offered with each job. Third, you need to consider the potential for overtime hours and how often you would work them.

Let's assume that the first job pays $45,000 for working 40 hours a week, 52 weeks a year, with no overtime. The second job pays $15 per hour for 40 hours a week, 52 weeks a year, and you can potentially earn time and a half for any hours worked beyond the 40 hours.

If the second job offers consistent overtime hours, then it could potentially provide a higher income compared to the first job. However, if the overtime hours are not guaranteed or if you prefer the stability of a fixed salary, then the first job with a salary of $45,000 would be a better option. Other factors to consider when finding work include job satisfaction, career growth opportunities, and work-life balance.

Final answer:

To determine which apartment Mrs. Cooper should choose, first list all available apartments with two bedrooms and a parking space. Next, compare the monthly rents to her income, aiming to spend no more than 30% on rent, and then consider other monthly expenses before making a final decision.

Explanation:

The student's question relates to determining which apartment Mrs. Cooper should choose based on her monthly income and her specific requirements of having a two-bedroom apartment and a parking space. Unfortunately, the question does not provide a list of available apartments with their respective rents, so I can't provide a specific recommendation. However, I can guide the student on how to make the decision.

First, Mrs. Cooper should list each available apartment that meets her criteria of having two bedrooms and a parking space. Next, she should determine the monthly rent for each of these apartments. Having this, she should compare the rent prices against her monthly income of $2,960 keeping in mind that a general rule of thumb is not to spend more than 30% of one's income on rent, which in her case would be $888 per month.

It is also important for Mrs. Cooper to account for additional monthly expenses (like utilities, groceries, and any other recurring payments) when determining affordability. If there are any apartments that fit these financial parameters, Mrs. Cooper can then choose the one that best fits her other personal preferences or needs.

Answer:

c = 6.5, a = 11.6

Step-by-step explanation:

2a + 3c = 42.7

3a + 5c = 67.3

Elimination

(2a+3c = 42.7)*3

(3a+5c = 67.3)*2

(1) 6a+9c = 128.1

(2) 6a+10c = 134.6

(2) - (1)

c = 6.5

Substitue 'c' in any of the equation

2a + 3(6.5) = 42.7 or 3a + 5(6.5) = 67.3

2a + 19.5 = 42.7 3a + 32.5 = 67.3

2a = 42.7 - 19.5 3a = 67.3 - 32.5

2a = 23.2 3a = 34.8

a = 11.6 a = 11.6

Answer:

y = 2x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (3, 10)

m = [tex]\frac{10-0}{3+2}[/tex] = [tex]\frac{10}{5}[/tex] = 2, thus

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 0), then

0 = - 4 + c ⇒ c = 0 + 4 = 4

y = 2x + 4 ← equation of line

The second robot working alone would spend 7.5 minutes to do the task.

To find the time it takes for the second robot to complete the task alone, we can utilize the concept of rate. Here's how:

Define rates:

Let R be the combined rate of both robots working together. We know they can complete the task in 5 minutes, so their combined rate is R = 1/5 tasks per minute (since rate = work done / time taken).

Let R1 be the rate of the first robot working alone. We know it takes him 15 minutes to complete the task, so R1 = 1/15 tasks per minute.

Relate rates:

The second robot's rate (R2) can be found by subtracting the first robot's rate from the combined rate: R2 = R - R1.

Calculate R2:

Substituting the known values: R2 = (1/5) - (1/15) = 2/15 tasks per minute.

Find time taken by second robot:

To find the time (T2) it takes for the second robot to complete the task alone, we can use the formula: T2 = 1 / R2.

Substituting the calculated rate: T2 = 1 / (2/15) = 15/2 = 7.5 minutes.

Therefore, the second robot will take 7.5 minutes to do the task alone.

To find the number of boats in the marina, we use the information given about the proportion of white, blue, and red boats. By setting up an equation and solving for the total, we find that there are 222 boats in the marina.

Explanation:

To find the number of boats in the marina, we need to start with the information given. The problem tells us that five-sixths of the boats in the marina are white, and then 25 of the remaining boats are blue. The rest of the boats are red, with a total of 12 red boats.

We can start by finding the fraction of boats that are red. Since five-sixths are white, the remaining fraction of boats that are not white is one-sixth. We know that 25 boats are blue, so if we subtract this from the one-sixth, we are left with the fraction that represents the red boats.

Let's set up an equation to solve for the total number of boats:

1/6 - 25 = 12

Simplifying the equation, we have:

1/6 = 12 + 25

1/6 = 37

Multiplying both sides of the equation by 6, we get:

1 = 37*6

1 = 222

Therefore, there are a total of 222 boats in the marina.

To determine how many cans are needed to hold 2,367 tennis balls, with each can holding 5 balls, you divide the total number of tennis balls by 5 and round up to the nearest whole number, resulting in 474 cans.

Explanation:

The subject of the question is Mathematics, as it involves a division problem. The question entails calculating the number of cans needed to hold 2,367 tennis balls, given that each can hold 5 tennis balls. To determine the number of cans required, we divide the total number of tennis balls by the number of balls that can fit in each can.

To find the solution:

Divide 2,367 by 5, which equals 473.4.

Since you can't have a fraction of a can, you would need to round up because you will need part of another can to hold the remaining balls. So, rounding 473.4 up, you get 474 cans.

Therefore, the Tennis Teams of Atlanta need to purchase 474 cans to hold 2,367 tennis balls.

The area of the figure PQRS can be found by applying the rule of areas in proportional shapes. The area of PQRS equals 32 square centimeters after rounding the calculated value.

The given problem involves the calculation of area and the application of ratios. It mentions two figures, ABCD and PQRS, along with certain dimensions and the area of the first figure. To find the area of the figure PQRS, we apply a rule of ratios used in geometry that states the areas of two similar figures is equal to the square of the ratio of their corresponding sides.

The corresponding sides here are DC and SR. So the ratio of their areas would be (DC/SR)². Plugging in the values we get = (10 centimeters/15 centimeters)² which simplifies to 0.444 (after rounding).

Then, to find the area of PQRS, we multiply the area of ABCD (which is 72 square centimeters) with the calculated square of the ratio. Therefore, the area of figure PQRS is 72 * 0.444 which equals 31.968 square centimeters (rounded to 32 square centimeters).
