The cat ate 3/7 of a bag per week when the food lasted for 7/4 week.

According to the question,

We have the following information:

Amira had 3/4 of a bag of cat food. The food lasted 7/4 weeks.

Now, we can easily find how much food Amira's cat ate in one week by dividing the total number of bags of food by the number of weeks the food lasted.

So, we have the following expression:

3/4 of a bag = 7/4 weeks

1 week = 3/4 ÷ 7/4

1 week = 3/4 * 4/7 of a bag

1 week = 3/7 of a bag

Hence, the cat ate 3/7 of a bag per week when the food lasted for 7/4 week.

Answer: MARK  ME BRAINLIEST I WORK HARD Soda consumption among children and teens is a health concern for a number of reasons. Drinking soda contributes to childhood weight issues, can lead to tooth decay,1 and can contribute to sleep problems. Some studies also suggest that kids who consume soda may have an increased risk for behavioral issues and mental health problems.

This article discusses the potential connection between soft drinks and behavioral problems, the limitations of this research, and other reasons to limit soft drink consumption in kids. It also covers some of the steps you can take if you are dealing with behavior issues and aggression in children.

Health Problems Associated Soft Drinks

Americans have some of the highest consumption rates of soda per capita worldwide.2 And many of those people consuming soda are very young children.

Over the years, there has been a big push to eliminate soft drinks from school vending machines and to educate parents about the risks associated with sugary drinks. Physicians and nutritionists have made it clear that soda provides children with empty calories and contributes to childhood obesity.

Dentists advise parents not to let children drink soda as well. Sugary drinks aren't good for children's teeth and may cause cavities.3

Most soft drinks also contain caffeine. Caffeine can cause headaches, upset stomach, jitteriness, and sleep problems. It’s also been associated with some behavioral problems and nervous system disorders in children.4

In children, it doesn’t take much caffeine to produce unwanted side effects. The American Academy of Pediatrics (AAP) discourages caffeine intake for kids of all ages.4

Recap

Soda and other sugary soft drinks pose a number of health risks including weight problems, dental cavities, headaches, and sleep problems.

Behavior Problems and Soft Drinks

If the health risks aren’t enough to dissuade parents from giving kids soda, the potential mental health concerns that might be associated with soft drink consumption might be a deterrent.

Research suggests that children who consume soda tend to have slightly higher scores on measures of aggression than do children who do not drink soda beverages. It's important to note, however, that the research only suggests that there is a correlation between soda consumption and aggressive behaviors; research has not proven a causal relationship, meaning that more research is needed to determine whether drinking soda causes this type of behavior.

In one 2013 study published in The Journal of Pediatrics found that aggression, withdrawal behavior, and attention problems are associated with soft drink consumption in young children.5

The researchers assessed 2,929 5-year-old children from 20 different U.S. cities. Even after adjusting for factors such as maternal depression, paternal incarceration, and domestic violence, soft drink consumption was still linked to aggressive behavior.

Children who drank four or more soft drinks per day were more than twice as likely to destroy other people's belongings, get into fights, and physically attack people.

However, it is important to note some flaws in the study that make it difficult to make assumptions about the potential impact of drinking soda. The study did not consider serving size, the type of soda, or what beverages specifically count as soft drinks.

While the study suggests there may be a correlation between drinking soda and behavioral aggression, it isn't enough to conclude that there is a causal connection.

One concerning point that this study indicates is that it is quite common for young children to consume soda. Forty-three percent of five years olds were reported to drink one serving of soda per day, while 4% reported drinking four servings per day.

Why Soda Might Affect Mental Health and Behavior

It’s unclear why soda consumption might be connected to aggressive behavior and other mental health issues. Soft drinks are highly processed, and there is not much research on how certain ingredients impact children. Some studies have linked aspartame to irritability6 and sodium benzoate to ADHD-related symptoms.7

Caffeine has also been linked to some behavior problems in children, so researchers suspect the caffeine content may play a role.

An underlying physical condition, such as low blood glucose levels, could also explain the link. Low blood glucose may cause children to crave soda while also causing them to become withdrawn or aggressive.8

However, further research is needed to understand how soda and mental health issues might be connected.

Recap

Soda may contain sugar, aspartame, sodium benzoate, and caffeine, and these ingredients may play a role in triggering negative side effects in kids.

The amount of money Rita will get after 5 year with interest rate compounds monthly is $4,420.

The formula for the calculation of the compound interest is-

A = P(1 + r/100n)∧nt

In which,

A  = amount after compounding

P = principal amount (  $20,000 )

n = number of time principal amount compounded in a year. ( 12 )

t = total time in years. (5 )

r = rate of interest (4%)

Put the value in eq.

A = 20,000(1 + 4/1200)∧5×12

A = 20,000×1.22

A = 24420

CI = A - P

CI = 24420 - 20000

CI = 4,420.

Thus, the amount of money Rita will get after 5 year with interest

To find the relation between mean and median;

The obtained mean = Sum of observations/number of observations

                                 = 0 + 0 + 1 + 1 + 1 + 3 + 3 + 4 + 5

                                 = 18/9

                                 = 2

Mean = 2

For median;

let us write the given observations in ascending order;

⇒  0, 0, 1, 1, 1, 3, 3, 4, 5

Here no. of observations is r = 9 which is an odd number.

b) For k = 4, the equation of bisector of [tex]\angle ABC[/tex] is

[tex]y = \frac{1}{3}x + 4[/tex]

What is distance formula?

Distance formula is used to find the distance between two coordinates.

If the coordinates of one point be ([tex]x_1, y_1[/tex]) and coordinates of other point is  ([tex]x_2, y_2[/tex]), then  distance between the two points is

[tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]

The points A, B and C have coordinates A(2, 8), B(9, 7) and C(k, k-2).

Length of AB =

[tex]\sqrt{(9 - 2)^2 + (7 - 8)^2}\\\\\sqrt{49 +1}\\\\\sqrt{50}[/tex]

Length of BC =

[tex]\sqrt{(k - 9)^2 + (k - 2 - 7)^2}\\\\\sqrt{(k - 9)^2 + (k - 9)^2}\\\\\sqrt{2(k-9)^2}\\\\(k-9) \sqrt{2}[/tex]

By the problem,

[tex](k-9)\sqrt{2} = \sqrt{50}\\k - 9 = \sqrt\frac{50}{2}}\\k - 9 = \sqrt{25}\\k - 9 = \pm 5\\k - 9 = 5 \ or \ k - 9 = -5\\k = 5 + 9 \ or \ k = 9 -5\\k = 14 \ or \ k = 4[/tex]

The other value of k is 14

b) When  k = 4

Coordinate of C = (4, 2)

Since AB =AC , the bisector of [tex]\angle ABC[/tex] passes through the midpoint of AC

Midpoint of AC =

[tex](\frac{2 + 4}{2} , \frac{8+2}{2})\\(3, 5)[/tex]

The line also passes through (9, 7)

Slope of the  bisector of [tex]\angle ABC[/tex] = [tex]\frac{7 -5}{9 - 3}[/tex]

                                                    = [tex]\frac{1}{3}[/tex]

Equation of the bisector of [tex]\angle ABC[/tex]

[tex]y - 5 = \frac{1}{3}(x - 3)\\\\y - 5 = \frac{1}{3}x -1\\\\y = \frac{1}{3} x - 1 + 5\\\\y = \frac{1}{3} x + 4[/tex]

The equation (D) y - 6 = 4(x+8) represents the line passing through the points (-8, 6) and (-11, -6).

The point-slope form can be used to get the equation of a straight line that traverses a specified point and is inclined at a particular angle to the x-axis. A line exists if and only if each point on it fulfills the equation for the line. This suggests that a linear equation in two variables can represent a line.

The given points are

(x₁, y₁) = (-8, 6)

(x₂, y₂) = (-11, -6)

So, the slope is given by

m = (y₂- y₁)/ (x₂- x₁)

= (-6 -6)/ (-11 -(-8)

= -12/ -3

= 4

Put (x₁, y₁) = (-8, 6) in the equation (y - y₁) = m (x- x₁)

y - 6 = 4(x-(-8)

y - 6 = 4(x+8)

A family has two cars. The first car has a fuel efficiency of 25 miles per gallon of gas, and the second has a fuel efficiency of 30 miles per gallon of gas. During one particular week, the two cars travelled a combined total of 1525 miles, for a total gas consumption of 55 gallons.

Let the volumes of gas consumed by the first car and the second car be denoted by the variables "x" and "y". We can form the given two equations using the given data.

x + y = 55

25x + 30y = 1525

We will substitute the value of "x" from the first equation into the second equation.

x = 55 - y

25x + 30y = 1525

25(55 - y) + 30y = 1525

1375 - 25y + 30y = 1525

5y = 150

y = 30
