To find out the number of groups of 1/5 in 3, we need to divide 3 by 1/5.
We can also write this as a fraction: 3 / (1/5)
To divide fractions, we flip the divisor and then multiply. This gives us:3 / (1/5) = 3 x 5/1 = 15So there are 15 groups of 1/5 in 3.To show this on a number line, we can first mark 0 and 3 on the number line.
Then we can draw 15 equally spaced tick marks between 0 and 3. Each tick mark represents 1/5, so 15 tick marks represent 15 groups of 1/5.
We can also label the tick marks with fractions to show that each tick mark represents 1/5.
The number line should look something like this:0 ------- 1/5 ------- 2/5 ------- 3/5 ------- 4/5 ------- 1 ------- 6/5 ------- 7/5 ------- 8/5 ------- 9/5 ------- 2 ------- 11/5 ------- 12/5 ------- 13/5 ------- 14/5 ------- 3

The measure of four angles of quadrilateral is 360°.
What is quadrilateral?
A closed quadrilateral has four sides, four vertices, and four angles.
It is a type of polygon.
In order to create it, four non-collinear points are joined.
Quadrilaterals always have a total interior angle of 360 degrees.
A polygon with four sides, four angles, and four vertices is called a quadrilateral.
The Latin words quadri, which means four, and latus, which means side, were combined to create the English word quadrilateral.
A quadrilateral is shown in the above image as an example.
A quadrilateral is a polygon with four vertices and four sides that each contain four angles, the sum of which is 360 degrees.
Two triangles are created when we draw a diagonal to a quadrilateral. These two triangles have a 180° angle sum.
As a result, the quadrilateral's total angle sum is 360°.
Hence, the measure of four angles of quadrilateral is 360°.

Which function has the lowest minimum value, and what are its coordinates?
A. Function 1 has the lowest minimum value, and its coordinates are (−1, −3).
B. Function 1 has the lowest minimum value, and its coordinates are (0, 1).
C. Function 2 has the lowest minimum value, and its coordinates are (−1, 0).
D. Function 2 has the lowest minimum value, and its coordinates are (0, 2).
Answer:
A. Function 1 has the lowest minimum value, and its coordinates are (−1, −3).
Step-by-step explanation:
To find the minimum value for f(x), set its first derivative to 0 and solve for x.
First derivative of f(x) is
f'(x) = 8x + 8 + 0 = 8x + 8
Setting this equal to 0 gives
8x + 8 = 0
8x = -8
x = -1
Plugging in this value for x in 4x² + 8x + 1 gives
f(x) = 4(-1)² + 8(-1) = 4 · 1 - 8 + 1
= 4 - 8 + 1
-4 + 1
= -3
So minimum for f(x) occurs at (-1, -3)
For g(x) the minimum is 0 and is at x = -1
So f(x) has minimum of -3 at x = -1
g(x) has minimum of 0 and occurs at x = -1
Answer:
A. Function 1 has the lowest minimum value, and its coordinates are (−1, −3).
Write the coordinates of the vertices after a dilation with a scale factor of 1/3, centered at the origin.
The coordinates of the vertices after a dilation with a scale factor of 1/3 centered at the origin is E'(0, -2), F'(3, -2), G'(3, 1) and H'(0, 1).
What is Dilation?Dilation is a type of transformation where the figure is enlarged or made smaller such that it preserves the shape but not size.
Every dilated image are similar figures to the original figure.
Given that center of the dilation is origin.
Any coordinate (x, y) when dilated to a scale factor k is (kx, ky).
The coordinates of the quadrilateral are E(0, -6), F(9, -6), G(9, 3) and H(0, 3).
Dilation is with a scale factor of 1/3.
So all the coordinates become (1/3x, 1/3y).
E(0, -6) becomes E'(0, -2)
F(9, -6) becomes F'(3, -2)
G(9, 3) becomes G'(3, 1)

What is 14/10 reduced??
The reduced form of 14/10 is 7/5. The answer is obtained using the method of simplifying fractions.
What is meant by simplifying fractions?
Making a fraction as simple as possible is referred to as simplifying (or reducing) a fraction.
To do this, we divide the denominator and numerator by the biggest number that can be divided exactly into both numbers. In other words, we choose the biggest common number between the top and bottom and divide it by that.
In a fraction, the numerator and denominator are referred to as the "terms." Thus, when we simplify a fraction, we cast it in its most basic mathematical form.
Now, to reduce 14/10, we will find the highest common factor of 14 and 10.
The highest common factor is 2 i.e. both numerator and denominator are divisible by 2.
So, on dividing both the terms by 2, we get
(14÷2)/(10÷2)= 7/5
Hence, the reduced form of 14/10 is 7/5.

Jarrod helped his teachers pack textbooks into boxes for the summer. He packed 6 boxes of science textbooks with 14 books per box. He also packed math textbooks with 12 books per box. If x represents the total number of boxes he packed, which of the following equations can be used to find the total number of books that Jarrod packed into boxes?
The total number of books that Jarrod packed into boxes can be represented by 84 + x*12.
The total number of books that Jarrod packed into boxes can be found by multiplying the number of boxes he packed with the number of books per box.
In this case, Jarrod packed 6 boxes of science textbooks with 14 books per box, so the number of books in the science boxes is 614 = 84. He also packed math textbooks with 12 books per box, so the number of books in the math boxes can be represented by x*12, where x represents the total number of boxes he packed.
So the total number of books that Jarrod packed into boxes can be represented by 84 + x*12.

To make a specific hair dye a hairstylist uses a ratio of one and 1/8 oz of red tone 3/4 oz of Gray tone and 5/8 oz of Brown tone if the stylist needs to make 20 oz of dye how much of each dye color is needed?
Answer: To make 20 oz of hair dye, the hairstylist needs to use 1 and 1/8 oz of red tone, 3/4 oz of gray tone and 5/8 oz of brown tone.
We can use proportionality to figure out how much of each dye color is needed.
Let's call the amount of red dye needed x, the amount of gray dye needed y and the amount of brown dye needed z.
According to the proportionality, we can write the following equation:
(1 + 1/8)x + (3/4)y + (5/8)z = 20
To find the amount of each dye color needed, we can solve this equation for x, y and z.
First, we can clear the fractions by multiplying all terms by 8:
(8 + 1)x + (6)y + (5)z = 160
Now we can solve for x:
9x + 6y + 5z = 160
x = (160 - 6y - 5z)/9
Similarly, we can solve for y and z:
y = (160 - 9x - 5z)/6
z = (160 - 9x - 6y)/5
Now we can substitute the desired amount of 20 oz into the equation and solve for x, y and z

All exponential functions pass through (0, 1)
We know that the exponential function f with base b is defined as:
f(x) = b^x
where b > 0 and b is not equal to 1
and x is any real number.
For x = 0,
f(0) = b^0
f(0) = 1
This means, the graph of function f(x) passes through (0, 1)
For example consider an exponential function f(x) = 2^x
For x = 0,
