Find the value of X
how do I find the value of it
To find the value of x, we use the quadratic formula on the equation x² + 0.00088x - 0.000484 = 0, resulting in two possible values for x, with the positive value being the valid solution in real-life contexts. In chemical equilibrium problems, the positive value is used to further calculate important quantities like pH.
Explanation:To find the value of x, we use the quadratic formula. Given the equation x² + 0.00088x - 0.000484 = 0, we can calculate the values for x that satisfy the equation. After applying the quadratic formula, we find two possible values for x, which are x = -0.0024 or x = 0.00139. However, in a real-life context, such as a chemical equilibrium problem, a negative concentration does not make sense. Therefore, we can disregard the negative value and conclude that x actually equals 0.00139.
In problems where x represents a concentration, once we've determined x = 0.0021, we could use this to calculate the concentration of H3O+, which would allow us to find the pH of the solution by plugging this concentration into the pH equation.
When defining what x represents, such as in a statistical context where we might be interested in the number of students who do their homework on time, x would be defined differently. It is essential to understand the context of a problem to accurately determine what x signifies and how to solve for it.
A car travels at a constant speed. What is the car's speed between checkpoints, expressed as a unit rate? Use the information given in the picture.
Answer:
The unit rate is 44 miles per hour.
Step-by-step explanation:
The difference between both the checkpoints is given by:
[tex]208-120=88[/tex] miles driven
Time taken to travel 88 miles = [tex]3-1=2[/tex] hours
As the car travels at a constant speed, so we get 88 miles driven in 2 hours.
Hence, per hour distance covered is = [tex]\frac{88}{2}=44[/tex] miles per hour.
If a man runs for a nd hour and a half at 8 miles an hour due South; and he continues south on a bus traveling at 55 miles an hour, for 24 minutes. How far did he travel
he ran 8 * 1.5 = 12 miles
the bus went : 55 * 24/60 = 22 miles
12 +22 = 34 miles total

Last year a company made a net profit of $20,000 on sales of $1,000,000. This year they made a net profit of $40,000 on sales of $1,000,000. When talking to the shareholders, they claimed that their profit increased by 100%, and asked for a bonus for doing so well. When talking to the union about a possible wage raise, they claimed that their profit only increased by 2%, which hasn't even kept up with inflation. How did they determine these figures? Which one do you think is correct?
Aiden weighs 39 pounds less than his older brother, Jacob. Jacob weighs more than 100 pounds. what could be the weight of the Two brothers?
We can determine that Jacob's weight is any number greater than 100 pounds, and Aiden weighs 39 pounds less than Jacob. Without an exact weight for Jacob, we cannot provide precise weights, only a possible range for both brothers.
To solve the question regarding Aiden and Jacob's weight, we can set up a simple algebraic equation. If Aiden weighs 39 pounds less than Jacob, and Jacob weighs more than 100 pounds, we can use variables to represent their weights.
Let's let J represent Jacob's weight. Therefore, Aiden's weight is J - 39 pounds. We're told that Jacob weighs more than 100 pounds, so J > 100.
For example, if Jacob weighed 110 pounds (which is more than 100 pounds), then Aiden would weigh 110 - 39 = 71 pounds. However, since we don't have an exact weight for Jacob, we cannot determine the exact weights but we can provide a range. Jacob's weight is any number greater than 100 and Aiden's weight is always 39 pounds less than Jacob's weight.

Tyler and his family drove from Atlanta to Baltimore. They traveled a total of 678 miles over 2 days. What is the reference point in this scenario?
Answer:- Atlanta is the reference point in this scenario.
Explanation:-
A reference point is a stationary place in a scenario which is used for comparison to determine if something is in motion. An object is in motion if it changes position respective to a reference point.
From the given situation, the reference point is Atlanta because Atlanta is the starting point such that the distance and time are computed from that point.

Elijah is planning a picnic. He will invite twice as many boys as girls. If he invites 18 people, how many boys and how many girls will get invitations?
The question is about ratios. Based on the condition, Elijah invited twice as many boys as girls which makes up a total of 18 people. We find out that Elijah invited 6 girls and 12 boys.
Explanation:This is a mathematical problem dealing with ratios. From the question, we know that Elijah plans to invite twice as many boys as girls, and the total number of guests will be 18 people.
Assume the number of girls Elijah is inviting is x. Therefore, the boys will be 2x (twice the number of girls).
Now, we form an equation which is the total number of people: x (girls) + 2x (boys) = 18. Solving for x, we get x = 6. So Elijah is inviting 6 girls and 2*6 = 12 boys.

At the end of a party, 3/4 cup of dip is left. Jim divides 4/5 of the leftover dip equally between 2 friends. How much dip does each friend get?
Final answer:
Each friend gets 3/10 cup of dip.
Explanation:
To calculate how much dip each friend gets, we first need to find the amount of dip Jim had after dividing.
Since 3/4 cup of dip was left and Jim divided 4/5 of that dip, we can calculate it as follows:
Amount of dip Jim divided = (3/4) * (4/5) = 3/5 cup
Since there are 2 friends, we divide the amount of dip Jim divided equally:
Amount of dip each friend gets = (3/5) / 2 = 3/10 cup
Therefore, each friend gets 3/10 cup of dip.

The gazelle football team made 5 plays, gaining 4 yards on each play . then they made 4 plays, loosing 10 yards on each play . What was the total change in their positions from where they started ?
Final answer:
The gazelle football team gained 20 yards initially and then lost 40 yards, resulting in a total change in position of -20 yards, ending up 20 yards behind their starting point.
Explanation:
The total change in position for the gazelle football team is determined by the yardage gained and lost during the different plays. Initially, the team gains 4 yards on each of 5 plays, which totals to 4 yards/play × 5 plays = 20 yards gained.
Then, the team loses 10 yards on each of 4 plays, which totals to 10 yards/play × 4 plays = 40 yards lost. To find the overall change in position, we subtract the yardage lost from the yardage gained: 20 yards gained - 40 yards lost = -20 yards.
Therefore, the total change in position from where they started is -20 yards, meaning that they ended up 20 yards behind where they started.
At the market 8 apples cost $4 how much do 9 apples cost ?
Answer:
$4.5.
Step-by-step explanation:
We have been given that at the market 8 apples cost $4.
Let us find the cost of 1 apple by dividing total cost of apples by total number of apples.
[tex]\text{Cost of 1 apple}=\frac{\$4}{8}[/tex]
[tex]\text{Cost of 1 apple}=\$0.5[/tex]
To find the cost of 9 apples we will multiply cost of 1 apple by 9.
[tex]\text{Cost of 9 apples}=\$0.5\times 9[/tex]
[tex]\text{Cost of 9 apples}=\$4.5[/tex]
Therefore, the cost of 9 apples will be $4.5.
According to the question,
Cost of 1 apple will be:
= [tex]\frac{4}{8}[/tex]
= [tex]0.5[/tex] ($)
hence,
The cost of 9 apples will be:
= [tex]0.5\times 9[/tex]
= [tex]4.5[/tex] ($)
Thus the above answer is correct.
