how do you do comparison for percents
Answers
In order to do a comparison for percents, you must convert them to decimal form and then juxtapose the decimal values side by side to see which is greater or less.
What are percents?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. The percent sign is commonly used, however the acronyms pct., pct, and sometimes pc are also used. A % is a number with no dimensions; it has no unit of measurement.
To calculate the percentage, divide the amount by the total value and multiply the result by 100.
Divide a percentage by 100 to get a decimal. So 25% is equal to 25/100, or 0.25. Multiply a decimal by 100 (simply shift the decimal point two places to the right) to convert it to a percentage. For example, 0.065 equals 6.5% and 3.75 equals 375%.

Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die. The white area indicates the sum of the numbers in the row and column.

Answers
The steps in solving the given expression shows that the result is:
0.92 * 10²
How to use Laws of Exponents?The expression is given as:
6.89 * 10⁻⁴/(7.5 * 10⁻⁶) = 0.92 * 10¹
The steps that Maggie followed are:
Step 1: Rewrite the given expression:
6.89 * 10⁻⁴/(7.5 * 10⁻⁶) = 0.92 * 10¹
Step 2: Divide the coefficients:
The coefficient of the numerator (6.89) is divided by the coefficient of the denominator (7.5) to get:
6.89 / 7.5 = 0.9186667.
Step 3: Divide the powers of 10:
This is done by subtracting the exponent of the denominator 10⁻⁶ from the exponent of the numerator 10⁻⁴ to get: 10²
Step 4: Combine the results:
This gives:
0.9186667 * 10²
Step 5: Simplify the coefficient:
She rounded the coefficient (0.9186667) to two decimal places, resulting in 0.92.

find the range of this equation
Answers
The range of the given equation is [-1, infinity).
We are given that;
Equation y= underroot(x+5)
Now,
The domain of this equation is the set of x values that make the expression under the square root non-negative.
That is, x+5 >= 0, or x >= -5. So the domain is [-5, infinity).
The range of this equation is the set of y values that are obtained by plugging in the domain values into the equation. Since the square root function is always non-negative, and we are subtracting 1 from it, the smallest possible value of y is -1, when x = -5. As x increases, y also increases, and there is no upper bound for y.
Therefore, by the range the answer will be [-1, infinity).

state the x-intercepts of the graph of the equation. Then find the coordinates of the vertex. The vertex and an ordered pair must be graphed on both sides of the vertex.
4. f(x) = 2x ^2- 9x + 9
Answers
Therefore , the solution of the given problem of coordinate comes out to be the vertex's dimensions are (9/4, 9/8).
What is coordinates ?A coordinate system is a method that employs one or more values or coordinates to accurately locate points or even other mathematical objects on a space, such as Euclidean space. Coordinates, that are pairs variables of numbers, are used to locate a point or object on a double plane.
Here,
2x^2 - 9x + 9 = 0
The quadratic formula can be used to find the roots:
=> x = [-(-9) ± √((-9)^2 - 4(2)(9))] / (2*2)
=> x = [9 ± √(9)] / 4
=> x1 = (9 + 3) / 4 = 3
=> x2 = (9 - 3) / 4 = 3/2
The x-intercepts of the equation's curve are therefore x = 3 and x = 3/2.
We can use the following algorithm to determine the vertex's coordinates:
=> x = -b / 2a
where b=-9 and a=2. By replacing these numbers, we obtain:
=> x = -(-9) / 2(2) = 9/4
We can change x = 9/4 into the formula f(x) = 2x2 - 9x + 9 to obtain the corresponding y-coordinate of the vertex:
f(9/4) = 2(9/4)^2 - 9(9/4) + 9 = 9/8
Therefore, the vertex's dimensions are (9/4, 9/8).
f(2) = 2(2)^2 - 9(2) + 9 = -5

Solve:
\(\begin{bmatrix}4x+2y=-6\\ 3x-2y=13\end{bmatrix}\) Since 2y - 2y = 0 we take that away now we have;
\(4x=-6\\3x=13\) Add 4x + 3x = 7x
\(\frac{7x}{7} =\frac{7}{7}\) Divide both sides by 7.
\(x=1\)
Now substitute x to find y.
\(4(1)+2y=-6\)
\(4 + 2y =-6\) Add 6 to the other side.
\(10 = 2y\) Divide both sides by 2.
\(\frac{10}{2} =\frac{2y}{2}\)
\(y = 5\)

10. Suppose that we have 50 balls labeled 0 through 49 in a bucket. What is the minimum number of balls that we need to draw to ensure that we get at least 3 balls which end with the same digit
Answers
Answer:
21 drawings
Step-by-step explanation:
The number labelings are 0 - 49
The minimum set that could be the same number is the labeling 0, 10 , 20
It could also be 1, 11, 21 or even 2,12,22
In all the cases, we can be sure that we might have three labelings ending with the same number when we pull our ball labeled 20
That makes a total of 21 drawings
Following are the response to the given question:
Pigeon Hole's Principle can also be used to tackle this problem. Assuming that we already have labels ranging from \(0\ to\ 49.\)
We possess five balls which conclude with the number 0 \(\text{(ball \ 0, ball\ 10, ball\ 20, ball\ 30, and\ ball\ 40)}.\) We possess five balls which conclude with the digit 1\(\bold{(ball\ 1, ball\ 11, ball\ 21, ball\ 31, ball\ 41)}.\) .....I have five balls that end in the number 9 \(\text{(ball\ 9, ball\ 19, ball\ 29, ball\ 39, and ball\ 49)}.\)Each digit ending is represented by five balls.
In the pigeonhole principle, it \(kn+1\) objects \((k \geq 1)\) are distributed among n boxes, one of the boxes will contain at least \(k+1\) objects. Assume that you draw a ball and place it in a box labeled with its last digit. So there will be n = 10 boxes.
Box 0: we place balls that end in the digit 0. Box 1: we place balls that end in the digit 1. .....Box 9 is where we put balls that end in the number 9.According to the pigeon hole concept, you need to draw \(kn+1\) balls to assure that at least one of the boxes includes \(k+1\) objects. Because \(k+1 = 3,\) we require three objects in at least one box (we need three balls ending with the same digit).
\(k + 1 = 3 \\\\k =2\)
Therefore, we have to draw \(kn+1\) balls, \(k = 2, n = 10\), at least\(21\ balls\) must be drawn to ensure that at least three of them have the same 1 digit.

Tanya has four times as many pens as Sanjay
So 4 times means four multiple of sanjay pens.
Tanya has four times as many pens as Sanjay can be write as 4x.
Combined of tanya and sanjay has 40 pens.
Combined means adding.
x+4x=40

the perimeter of a rectangle is 900cm if its length its twice its width clacualte the length and width
Answers
The length of the rectangle is 300 cm and its width is 150 cm, given that the perimeter is 900 cm and the length is twice the width.
Let's assume that the width of the rectangle is w, then the length of the rectangle is twice the width, 2w.
The perimeter of a rectangle is given by the following formula:
Perimeter = 2 * (Length + Width)
Substituting the values given, we get:
900 = 2 * (2w + w)
Simplifying this equation, we get:
900 = 6w
Dividing by 6 on both sides, we get:
w = 150
Now that we know the width of the rectangle is 150cm, we can find its length as follows:
Length = 2 * Width = 2 * 150 = 300
Therefore, the length of the rectangle is 300 cm and its width is 150 cm.

Reuben made a shirt using 7/8yards of red fabric and 1/4yards of yellow fabric. How many more yards of red fabric did Reuben use?
Answers
Answer and Step-by-step explanation:
To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:
7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8
So, Reuben used 5/8 yards more red fabric than yellow fabric.
