Answer:
1. Kevin has 12 pieces of paper.
2. Including Sybill and her friends, each person will get 1/8 of the 1/2 slice.
Step-by-step explanation:
1. This is because if 1 piece of paper turned divided into fourths would 4/1 or 4 “fourths” of paper. So multiply that by 3 since there is 3 pieces of paper and we are following the same steps. 3 x 4 = 12. Hence if you divide 3 pieces of paper into fourths, you will have 12 fourths.
2. Since we are splitting the 1/2 piece four (which includes sybill and her 3 friends) ways, the equation would be: 1/2 divided by 4
Divide:
1/2 divided by 4-
1/2 : 4 = 1/2 · 1/4 = 1 · 1/2 · 4 = 1/8
Hence, each friend and Sybill her self will receive a 1/8 piece.
Are the lines with the equation y = -5x + 1 and y = -5x + 8 parallel? (use a graph, might help)
Answer:
Yes, the lines y = -5x + 1 and y = -5x + 8 are parallel. This is because they have the same slope (-5) but different y-intercepts (1 and 8). Parallel lines have the same slope, and different y-intercepts.
Answer:
For y = -5x + 1
x = [tex]\frac{1-y}{5}[/tex].
And
y = 1 - 5x.
Put on a graph: look at picture 1.
The for y = -5x + 8
x = [tex]\frac{8-y}{5}[/tex]
And
y = 8 - 5x.
Put on a graph: look at picture 2.
These two lines are parallel.
Exactly $9 was used to purchase an equal number of each of the three types of tokens
$0.10, $0.15 and $0.20, how many of each type of tokens were purchased?
A)45
B)30
C)25
D)20
E)15
Answer:
The answer is 20, so the answer is (D) 20.
Step-by-step explanation:
Let's say x is the number of tokens purchased for each of the three types. Then, the total amount spent is 0.10x + 0.15x + 0.20x = $9.
Combining like terms, we get 0.45x = $9.
Finally, dividing both sides by 0.45, we get x = 20.
So, 20 tokens were purchased for each of the three types.
The answer is 20, so the answer is (D) 20.
If a hexagon represents 1 whole, what fraction does each of the following shapes represent? Be prepared to show or explain your reasoning
The triangle represents 1/4 of the whole trapezoid, the rhombus represents 1/2 of the whole trapezoid, and the hexagon represents 1/1 of the whole trapezoid.
Determine the fractionEach of the shapes represent a different fraction of the whole trapezoid.
The triangle represents 1/4 of the whole trapezoid. This is because there are four triangles in the trapezoid, and each one is equal in size. Therefore, each triangle is 1/4 of the whole trapezoid. The rhombus represents 1/2 of the whole trapezoid. This is because there are two rhombuses in the trapezoid, and each one is equal in size. Therefore, each rhombus is 1/2 of the whole trapezoid.
The hexagon represents 1/1 of the whole trapezoid. This is because there is only one hexagon in the trapezoid, and it is equal in size to the whole trapezoid. Therefore, the hexagon is 1/1, or the whole trapezoid.
In conclusion, the triangle represents 1/4 of the whole trapezoid, the rhombus represents 1/2 of the whole trapezoid, and the hexagon represents 1/1 of the whole Hexagon. These fractions can be used to determine the value of each shape in relation to the whole trapezoid.

A quadrilateral has two angles that measure 232° and 86°. The other two angles are in a ratio of 4:17. What are the measures of those two angles?
The two missing angles of the quadrilateral are 10.5° and 2.47°, calculated from the given angles of 232° and 86°, and a ratio of 4:17.
The angle sum of a quadrilateral is 360°. Therefore, we need to find the sum of the two missing angles.We can start by subtracting the two known angles from the total angle sum and then dividing the difference by the ratio given.
360° - 232° - 86° = 42°
To find the two missing angles, divide the sum by the ratio given.
42° ÷ 4:17
The find the measure of the first angle, divide 42° by 4:
42° ÷ 4 = 10.5°
To find the measure of the second angle, divide 42° by 17:
42° ÷ 17 = 2.47°

The required equation which intersects the points (12, -2) and (6, -8) in the point-slope form is y+2 = x-12.
What is point-slope form?The general form of a linear equation is y-y1=m(x-x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).
To understand more about it and see some instances, watch this video.
Both the slope-intercept form and the point-slope form can be used to write the equation of a straight line.
The slope and ANY point on the line are highlighted using the point-slope form.
Slope intercept form merely shows the slope and the y-intercept of a line.
So, we have:
m = 1
And points are (12, -2) and (6, -8)
We need to use the points: (12, -2)
Now, form the equation as follows:
y - (-2) = m (x-12)
y + 2 = 1(x-12)
y+2 = x-12
Therefore, the required equation which intersects the points (12, -2) and (6, -8) in the point-slope form is y+2 = x-12.

Can a continuous random variable take all values in an interval?
A continuous random variable can take all values in an interval, assuming that the interval is unbounded.
This is because a continuous random variable has an infinite number of possible outcomes, and the probability density function (PDF) of a continuous random variable is defined over a range of values rather than specific values.
For example, consider the normal distribution, which is a common continuous probability distribution. The PDF of a normal distribution is a bell-shaped curve that extends from negative infinity to positive infinity.
This means that a continuous random variable following a normal distribution can take any value on the real number line, with some values being more likely than others.
However, if the interval is bounded, then it is possible for a continuous random variable to not take all values within the interval. In this case, the probability density function is zero outside of the interval, and the random variable is restricted to the range of values within the interval.

What is a linear function?In Mathematics, a linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate. This ultimately implies that, a linear function has the same slope and it is typically used for uniquely mapping an input variable to an output variable, which both increases simultaneously.
Next, we would determine the slope by using the points contained in the table as follows;
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (5 - 1)/(0 + 1)

What is a rectangle?A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.
We are given that the breadth of the rectangle is half of its length, so we can write:
B = 0.5L
We are also given that the perimeter of the rectangle is 76m. The perimeter of a rectangle is the sum of the lengths of all four sides, which in this case is:
Perimeter = 2(L + B)
Substituting the value of B from the first equation, we get:
Perimeter = 2(L + 0.5L)
Perimeter = 2(1.5L)
Perimeter = 3L
Now we can solve for L:
3L = 76
L = 25.33
So the length of the rectangle is 25.33 meters.
To find the breadth, we can substitute this value of L back into the first equation:
B = 0.5L
B = 0.5(25.33)
B = 12.67
So the breadth of the rectangle is 12.67 meters.
Therefore, the length and breadth of the rectangle are 25.33 meters and 12.67 meters, respectively.

Given, the distance traveled by an object in t = 30 minutes is 2 miles
Let "v" be the final velocity of an object,
"u" be the initial velocity of an object,
and "a" be the acceleration of an object.
From the standard velocity equation:
final velocity = initial velocity + acceleration * time.....(1)
(final velocity)² = (initial velocity)² + 2*acceleration * distance....(1)
From equation (1)
v = u + a*30 minutes
time in hours,
v = u + 0.5a
From equation (2)
