A storage tank is 20% filled with water. The storage tank holds, 1,160 gallons of water. How many gallons of water are needed to fill the storage tank to the top?
The storage tank requires an additional 4,640 gallons of water to be filled to the top, calculated by finding the total tank capacity using the 20% already filled and subtracting the current water volume.
The student asks about the amount of water needed to fill a storage tank to the top given that the tank is already 20% full with 1,160 gallons of water. To find out how much more water is required, we first need to establish the total capacity of the tank.
Since 1,160 gallons represent 20% of the tank's capacity, we can calculate the full capacity by dividing the amount of water currently in the tank by 0.2. After finding that number, we need to subtract 1,160 from the total capacity to find the amount of water needed to fill the tank.
Calculation:
1. Calculate the full capacity of the tank:
Total capacity = 1,160 gallons / 0.20 = 5,800 gallons.
2. Calculate the gallons of water needed to fill the tank:
Gallons needed = Total capacity - Current amount of water
Gallons needed = 5,800 gallons - 1,160 gallons = 4,640 gallons.
Therefore, 4,640 gallons of water are needed to fill the storage tank to the top.

Jay won 14 out of the last 20 video games he played. Find the probability of Jay winning the next video game he plays.
Answer:
0.7 or 70 percent
Step-by-step explanation:
Jay's probability of winning the next game, based on his past record, would be 70%. However, probability doesn't guarantee future outcomes as the future performance depends on various factors.
Explanation:The question requires us to find out the probability of Jay winning the next video game he plays, given his past record. Jay has won 14 out of the last 20 games, which gives us a winning probability of 14/20 = 0.7 or 70%. Probability assumes the conditions remain the same, it doesn't guarantee that the next outcome will be a win.
However, notice that past performance doesn't necessarily indicate future results, especially in random situations such as a game. The future outcome depends on the conditions of the next game he plays and his performance in it. The past winning record of 70% can be taken as an indication of Jay's skills or chances under similar conditions, but not a certainty for future games.

Step-by-step explanation:
Subtract one from both sides to get the answer above.
To graph it, choose the open arrow pointing right and drop it over 2.
Answer:
x>2
Step-by-step explanation:
You would simplify this as you would any other equation, which means subtract the 1 from each side to be left with x > 2
To graph this, you would use an open circle, because the sign is not greater then and equal to, it is only greater then.
Therefore, to graph it, you would have an open circle to the right on the number 2

during the last few months, maria has seen deer in her backyard on 13 days and no deer on 52 days. What is the approximate probability that she will see deer in her yard tomorrow?
A) 0.25
B)1/5
C) 33.3 %
D) 2/3
Answer:
B) 1/5
Step-by-step explanation:
First you would have to find the total number of days.
52 + 13 = 65
The total number of days is 65.
Reread the question. The question is, "What is the approximate probability that she will see deer in her yard tomorrow?"
She has seen deer in her yard for 13 days, so the equation to figure this out would be:
13 divided by 65 = 0.2 or 1/5
I also took the Quiz and got it correct :)
(If you found this helpful and got it correct please thank, give 5 stars, and comment your feedback if you can so others know it's correct as well.)
The probability of seeing a deer in her yard tomorrow is 1/5, the correct option is B.
What is Probability?Probability is the likeliness of an event to happen, it has a range from 0 to 1.
Total number of days Maria saw deer is 13 days
Total number of days Maria didn't saw the deer is 52 days
The total number of days is 65
Probability of seeing a deer = Number of days deer was seen / Total
number of days
Probability = 13/65
Probability = 1/5

Select all of the following that are quadratic functions.
x = 3y2 – 6y + 5
y + 3 = –2 x 2+ 5
y = 2 x 2 – 8 x + 6
y= –7 x – 4
y – 3 x = 4 x 3 – x2 + 9
y = 5 x(x + 9) – 8
y – 2 x 2 = 3 x – 2 x 2 + 4
2. y + 3 = -2x^2 + 5
3. y = 2x^2 - 8x + 6
6. y = 5x (x+9) - 8
Out of the given functions, y + 3 = –2 x 2+ 5, y = 2 x 2 – 8 x + 6, y = 5 x(x + 9) – 8 and y – 2 x 2 = 3 x – 2 x 2 + 4 are quadratic functions. They fit the standard quadratic form a*x^2 + b*x + c = y.
Explanation:A function can be classified as a quadratic function if it can be written in the standard form a*x^2 + b*x + c = y, where a, b, and c are constants and a is not equal to zero. Quadratic functions graph as a parabola.
x = 3y2 – 6y + 5: This is not a quadratic function in y due to its form.y + 3 = –2 x 2+ 5: This is a quadratic function in variable 'x' once rearranged to the standard form.y = 2 x 2 – 8 x + 6: Thus is a quadratic function.

Suppose Theta is an angle in standard position whose terminal side lies in
Quadrant 3. If sine--12/13, find the value of tan Theta
A. -12/5
B. 13/5
C. 5/12
D. 12/5
The correct answer is tan Theta = 12/5.
The task is to find the value of tan Theta given that in a position where its terminal side lies in Quadrant 3 and sine is -12/13. In the third quadrant, both sine and tangent are negative, so we expect a negative ratio for tan Theta. Since sine equals opposite over hypotenuse, we have:
sin Theta = opposite/hypotenuse = -12/13
The negative sign indicates that the opposite side is in the negative direction (downward in this case).
To find tan Theta, we'll use the Pythagorean theorem to find the length of the adjacent side:
opposite^2 + adjacent^2 = hypotenuse^2
(-12)^2 + adjacent^2 = 13^2
144 + adjacent^2 = 169
adjacent^2 = 169 - 144
adjacent^2 = 25
adjacent = [tex]\sqrt{5}[/tex]
Because we're in the third quadrant, where the x-coordinate (adjacent side in the context of the unit circle) is negative, adjacent = -5.
Now, tan Theta = opposite/adjacent = -12/-5 = 12/5.
Therefore, the correct answer is D. 12/5.

Which of the following statements best describes the "grouping method" of factoring trinomials?
Choose the correct answer below.
O A. The grouping method of factoring trinomials involves separating the first and last terms of the trinomial into respective factors, and then factoring by
grouping
OB. The grouping method of factoring trinomials involves rewriting the bx term into the factors that fit the particular trinomial, and factoring these four terms using
grouping
OC. The grouping method of factoring trinomials involves factoring out the common factor.
Final answer:
The grouping method of factoring trinomials involves separating the first and last terms of the trinomial into respective factors, and then factoring by grouping.
Explanation:
The correct answer is A. The grouping method of factoring trinomials involves separating the first and last terms of the trinomial into respective factors, and then factoring by grouping. In this method, we find two pairs of terms with common factors and group them together. Then, we factor out the greatest common factor from each pair. Finally, we factor out a common factor from the resulting binomials. Let's consider an example:
Example:
Factor the trinomial: x^2 + 5x + 6
Step 1: Separate the first and last terms: x^2 + 5x + 6 = (x^2 + 2x) + (3x + 6)
Step 2: Factor out the greatest common factor from each pair: x(x + 2) + 3(x + 2)
Step 3: Factor out a common factor from the resulting binomials: (x + 2)(x + 3)
Therefore, the factored form of the trinomial x^2 + 5x + 6 is (x + 2)(x + 3).
Valerie said that the GCF of two monomials is 7bc.
What two monomials did she use?
Answer: B: 35ab^2c AND 7bc^2
Step-by-step explanation:
The monomials must be multiples of 7bc such as 21b^2c and 14bc^2, because the GCF of two monomials is the highest factor that divides both these monomials. GCF in this case is 7bc.
Explanation:The Greatest Common Factor (GCF) of two monomials is the highest factor that divides both of these monomials. Given that the GCF is 7bc, these two monomials must have 7bc as a factor. Thus, Valerie possibly used any two monomials that are multiples of 7bc.
For example, one answer could be 21b^2c and 14bc^2. Each of these monomials has 7bc as a factor (3b, 2c, and 2b, 2c respectively). There are other possible combinations, as long as they're multiples of 7bc.
