The fractions One-fourth, One-half, Three-twelfthsand are shown below. Top: A fraction bar divided into 4 parts. 1 is shaded. Middle: A fraction bar divided into 2 parts. 1 is shaded. Bottom: A fraction bar divided into 12 parts. 3 are shaded. Which is a correct comparison of these fractions? One-fourth equals three-twelfths One-half is less than three-twelfths One-fourth is greater than one-half Three-twelfths is greater than one-fourth
Answer:
One-fourth equals three-twelfths
Step-by-step explanation:
From the above question:
The fractions
One-fourth
: A fraction bar divided into 4 parts. 1 is shaded.
One-half
A fraction bar divided into 2 parts. 1 is shaded
Three-twelfths:
A fraction bar divided into 12 parts. 3 are shaded.
Which is a correct comparison of these fractions?
Comparing the options
a) One-fourth equals three-twelfths
= 1/4 = 3/12
Divide numerator and denominator by 3
= 3 ÷ 3 /12 ÷ 3
= 1/4
Option a is correct
b) One-half is less than three-twelfths
1/2 < 3/12
This statement above is wrong.
One half is greater than three twelfths
1/2 is > 3/12
1/2 > 1/4
c) One-fourth is greater than one-half
1/4> 1/2
This statement above is wrong.
1/2 is greater than 1/4
d) Three-twelfths is greater than one-fourth
This is statement is wrong. Three -twelfths is equal to one - fourths
The correct comparison of these fractions is One-fourth equals three-twelfths.
Two manufacturing teams are producing light bulbs. The tables show their production over 5 days. Team Red Production Team Blue Production Day Total Day Total 1 5 1 5 2 10 2 10 3 12 3 15 4 14 4 20 5 25 5 25 Which team has a constant rate of change? Explain your answer.
Answer:

Step-by-step explanation:
The reason this is, is because for each day that passes, they make 5 more light bulbs. This is in relation to the days that pass.
The volume V (in cubic feet) of a rectangular room can be modeled by V(x)= 2x^3-14x^2+12x, where x is the length (in feet) if the room. Factor the function. Use your factorization to determined the values of x for which the model makes sense
Answer:
The values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].
Step-by-step explanation:
From statement we have the following expression for the volume of the rectangular room is:
[tex]V(x) = 2\cdot x^{3}-14\cdot x^{2}+12\cdot x[/tex] (1)
Where:
[tex]V[/tex] - Volume of the rectangular room, measured in cubic feet.
[tex]x[/tex] - Length of the room, measured in feet.
By Algebraic means we factorize the polynomial:
[tex]V(x) = x\cdot (2\cdot x^{2}-14\cdot x +12)[/tex]
[tex]V(x) = x\cdot (x-6)\cdot (x-1)[/tex]
Given that both volume and length must be positive variables, then the following conditions must be satisfied:
[tex]x \ge 0\,ft\,\land\,x\ge 6\,ft\,\land\,x\ge 1\,ft[/tex]
Then, the values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].

Step-by-step explanation:
We can split the figure into a 6 by 15 rectangle and a parallelogram (8 base, 7 height).
The area of the rectangle is 6•15=90The area of the parallelogram is 8•7=5690+56=1468. What is the solution of the equation 4x + 12 = 48 ?
a) x= 9
b) x= 15
c) x= 144
d) x= 240
Answer:
A) x=9
Step-by-step explanation:
48-12=36.
36/4=9
More detailed explanation:
4x+12=48
-12 -12
4x = 36
/4 /4
x = 9
The solution of the equation is, x = 9.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The equation is,
⇒ 4x + 12 = 48
Now, We can solve the equation for value of x as;
⇒ 4x + 12 = 48
Subtract 12 both side, we get;
⇒ 4x + 12 - 12 = 48 - 12
⇒ 4x = 36
Divide by 4;
⇒ 4x/4 = 36/4
⇒ x = 9

8(1/2) + 2(4)
/2
4 + 8
/2
12/2
6
Answer:
The answer is 6.
Step-by-step explanation:
SInce x = 1/2, we multiply 8 by 1/2 which is 4.
y = 4, so 2 x 4 = 8. 8 + 4 = 12.
we divide by z, which is 2, so 12 ÷ 2 = 6.

What is f(x)=|x| when it is vertically scaled by a factor of 4, reflection in the y axis, and translated 7 units up and 1 unit to the right?
Answer:
(1,3)
Step-by-step explanation:
starting at (0,0)
vertically scaled by 4 - go up four (0,4)
reflected on y axis - negative the four (0,-4)
translated 1 to the right and 7 up - go up 7 and to the right 1 (1,3)

the answer to graph one is 1 and the second one answer is 2
Step-by-step explanation:
the other guy made it a hassle for no reason
The graph shown in figure 1 is a function, and the graph shown in figure 2 is not a function
What are graphs?Graphs are the visual way of representing functions and equations
For a graph to represent a function, then the graph of the function must pass the vertical line test
Graph 1 will pass the vertical line test, while graph 2 will not
Hence, the graph shown in figure 1 is a function, and the graph shown in figure 2 is not a function

a square with a side length of 2 units is drawn on the coordinate plane with a vertex at the origin. Which shows a dilation of the square by a scale factor of 2
Answer:
Step-by-step explanation:
From the figure attached,
ABCD is a square with vertices as,
A(-2, 0), B(-2, 2), C(0, 2) and D(0, 0)
If the given square is dilated by a scale factor of 2 and the center of dilation is the point D (origin).
Rule for the dilation of a point by a scale factor k is,
(x, y) → (kx, ky)
By this rule,
A(-2, 0) → A'(-4, 0)
B(-2, 2) → B'(-4, 4)
C(0, 2) → C'(0, 4)
D(0, 0) → D'(0, 0)
Now we can plot these points to get the image square (dilated figure) as given the figure attached.

Answer:
107
Step-by-step explanation:
Since we know that the triangles have the same 3 sides, they are congruent (SSS). We also know that a triangle's angles add up to 180 degrees.
We first need to add 41 and 32 to give us the number we need to subtract from 180.
41+32=73
Now we need to subtract from 180 degrees.
180-73=107
If 107 is the measure of angle D, then according to SSS congruence it is also the measure of angle B.

Answer:
[tex]\displaystyle -0.\overline{37}=-\frac{37}{99}[/tex]
Step-by-step explanation:
Convert a Repeating Decimal to a Fraction
We need to convert the following decimal to a fraction:
[tex]-0.\overline{37}[/tex]
Let's call x to the given number:
[tex]x=-0.\overline{37}[/tex]
The number has two repeating (periodic) decimals, thus we multiply by 100:
[tex]100x=-37.\overline{37}[/tex]
Note the decimals continue to repeat exactly like the original number.
Subtracting both expressións, the repeating decimals are simplified:
[tex]100x - x = -37[/tex]
Operating:
99x=-37
Dividing by 99:
[tex]\displaystyle x=-\frac{37}{99}[/tex]
The fraction cannot be simplified, thus:
[tex]\mathbf{\displaystyle -0.\overline{37}=-\frac{37}{99}}[/tex]
