Your credit card limit is $5,000, and your current balance is $4,500. Your credit score will increase by 10 points for every $250 decrease in your balance. At the end of the year you have paid down your balance to $2,500. By how many points has your credit score increased?
Answer:
80
Step-by-step explanation:
4500-2500 is 2000 dollars reduction, or money paid off.
For every 250 dollars, there is a 10 points increase. 2000 divided by 250 is 8. There are 8 sets of 250 dollars. So, for every 250 dollars (you have 8 of them), 10 points increase. Therefore, you multiply 10 by 8.
10x8 = 80. Your credit score has increased by 80 points.
At the end of the year, my credit score would have increased by 80 points.
If my current balance is $4500 and at the end of the year, my balance is $2500. It means that the total decrease in my credit balance is $2000 ($4500 - $2500).
In order to determine the total increase in the number of points, the first step is to determine the amount of 250 that is in 2000. In order to do this, the first step would be to divide 2000 by 250.
2000 / 250 = 8
The second step is to multiply 8 by 10
8 x 10 = 80 points.

Answer:
Quadratic equations are actually used in everyday life, as when calculating areas, determining a product's profit or formulating the speed of an object. Quadratic equations refer to equations with at least one squared variable, with the most standard form being ax² + bx + c = 0.
Here is an example:
Antoine stands on a balcony and throws a ball to his dog, who is at ground level.
The ball's height (in meters above the ground), xxx seconds after Antoine threw it, is modeled by:
h(x)=-2x^2+4x+16h(x)=−2x

2x2 + 5x + 3 = 0 = In this one a=2, b=5 and c=3
Hope that was helpful.Thank you!!!
Answer:
see below
Step-by-step explanation:
Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring. While factoring may not always be successful, the Quadratic Formula can always find the solution.
The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.
The Quadratic Formula is derived from the process of completing the square, and is formally stated as:
The Quadratic Formula: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by:
-b ± [tex]\sqrt{b^2 - 4ac}[/tex]

Your water bill lists a previous reading of 5,520 ccf and a present reading of 5,981 ccf. The water company charges $0.93 per ccf of water. How much will you be charged on the current bill?
Answer:
$428.73
Step-by-step explanation:
The previous reading of the water bill is 5,520 ccf and a present reading of 5,981 ccf.
The number of units used is given as the present reading minus the previous reading.
This means that the number of units used is:
5981 - 5520 = 461 ccf
The water company charges $0.93 per ccf of water.
Therefore, the charges on the current bill will be:
0.93 * 461 = $428.73

Suppose that an urn contains 3 black marbles, 7 yellow marbles, and 10 green marbles. If one marble is selected, determine the probability that it is green. The answer should be an integer or a simplified fraction.
Answer:
1/2
Step-by-step explanation:
Simple probability is a ratio of the number of ways the thing we want to happen can to the total possible outcomes.
(For example, we flip a coin and want heads, but it can land on heads or tails. Our probability of getting heads is 1/2, one way to get heads over the 2 possible outcomes)
So for this problem, there's 20 possible things that CAN happen (3 + 7 + 10) and 10 ways we get what we want (a green marble).
Our probability of getting a green marble is [tex]\frac{10}{20\\}[/tex], which simplifies to [tex]\frac{1}{2}[/tex]
Which expression is equivalent to 8g+2+4g-2-2g
Answer:
10g
Step-by-step explanation:
add 8g,4g and -2g to get 10g
add 2 and -2 to receive 0
the simplified expression would be 10g
The equivalent expression for 8g + 2 + 4g - 2 -2g after combining like terms is 10g.
The original expression given is 8g + 2 + 4g - 2 -2g. To find an equivalent expression, we need to combine like terms. We do this by adding or subtracting the coefficients of identical variables and also combining any constant terms.
In this case, we combine the coefficients of g:
8g + 4g - 2g = (8 + 4 - 2)g = 10g.
Next, we combine the constant terms: 2 - 2 = 0. Since adding or subtracting 0 does not change the value, we can ignore this part.
Thus, the equivalent expression is simply 10g.

A bag contains 40 tickets, each numbered between 1-40. If a ticket is drawn at random, find the probability of it being odd or less than 26
Answer:
you have a 50% chance of getting an odd number and a 60% chance of getting a number less than 26.
Step-by-step explanation:
Between 1 and 40 there are 20 odd numbers
20÷ 40 x 100=50, This means you have a 50% (20:20) chance of getting an odd number.
Between 1 and 40 there 25 numbers less than 26
15÷25 x 100=60, This means you have a 60% (25:15) chance of getting a number under 26.
Final answer:
The probability of drawing an odd ticket or a ticket numbered less than 26 from a bag containing 40 numbered tickets is 4/5 or 0.8, meaning there is an 80% chance to draw such a ticket.
Explanation:
To find the probability of drawing an odd ticket or a ticket numbered less than 26 from a bag containing tickets numbered 1-40, we need to consider the total number of favorable outcomes for each separate event and be careful not to double-count any outcomes that satisfy both conditions.
Firstly, there are 20 odd numbered tickets (1, 3, 5, ..., 39) which satisfy the first condition. For the second condition, there are 25 tickets that are numbered less than 26 (1, 2, 3, ..., 25).
However, half of the tickets less than 26 are odd (1, 3, 5, ..., 25), which we've already counted. So, we should only add the even numbered tickets that are less than 26 to get the total number of favorable outcomes. There are 12 even numbered tickets less than 26 (2, 4, 6, ..., 24).
Adding the odd numbered tickets (20) to the unique even numbered tickets less than 26 (12), we get a total of 32 favorable outcomes.
Since there are 40 tickets in total, the probability of drawing a ticket that is either odd or less than 26 is 32/40.
To simplify, divide both numerator and denominator by their greatest common divisor which is 8, giving us 4/5 or 0.8, which means there's an 80% chance of drawing a ticket that meets the criteria.

a large water tank measures 6 feet across and 4 feet high. it is being filled with water at a rate of 10 gallons per minute. about how many hours will it take to fill the pool if 1 cubic feet of water is about 7.5 gallons? round to the nearest tenth.
At the given rate, it would take 1.2 hours to fill the tank described.
Calculating the VolumeTo find out how many hours it will take to fill the water tank, we need to calculate the volume of the tank and then determine the time it takes to fill it at a rate of 10 gallons per minute.
The volume of the tank can be calculated using the formula for the volume of a rectangular prism.
length x width x height:Volume = 6 feet x 4 feet x 4 feet = 96 cubic feet
Convert this volume to gallons, knowing that 1 cubic foot is about 7.5 gallons:
96 cubic feet x 7.5 gallons/cubic foot ≈ 720 gallonsSo, the tank has a capacity of approximately 720 gallons.
To find the time it takes to fill the tank at a rate of 10 gallons per minute:
Time (minutes) = Volume (gallons) / Rate (gallons per minute)
Time (minutes) = 720 gallons / 10 gallons per minute = 72 minutes
Now, to convert this to hours, divide by 60 (since there are 60 minutes in an hour):
Time (hours) = 72 minutes / 60 minutes per hour ≈ 1.2 hours
Rounded to the nearest tenth, it will take about 1.2 hours to fill the water tank.

To determine the time to fill the tank, calculate the tank volume in cubic feet, convert that to gallons, and then divide by the rate of water flow and 60 to get the time in hours.
Explanation:To determine how long it will take to fill the tank, we first need to calculate the volume of the tank in cubic feet. The tank is shaped like a cylinder, so the volume V of a cylinder is given by V = πr²h, where r is the radius and h is the height. In this case, the tank has a radius of 3 feet (half of the 6 feet diameter) and a height of 4 feet, so V = π(3)²(4) = π(9)(4) = 36π cubic feet.
Next, we need to consider that 1 cubic foot is equivalent to 7.5 gallons of water. Therefore, the tank capacity in gallons is 36π * 7.5.
We are told the tank is being filled at a rate of 10 gallons per minute. To determine how long it will take to fill the tank, we divide the total number of gallons the tank holds by the rate at which the tank is being filled. This will give the total time in minutes. To convert this time to hours, we then divide by 60, as there are 60 minutes in an hour.
So, the number of hours to fill the tank is (36π * 7.5) / 10 / 60, rounded to the nearest tenth.
