Which of the following is a true stateme 3/4 < 4/6; 5/6 > 10/12; 8/16 = 1/4; 11/15 < 4/5
Answer:
11/15 < 4/5
Step-by-step explanation:
this is because:
3/4 < 4/6 is the same as 9/12 < 8/12 which is incorrect
5/6 > 10/12 is the same as 10/12 > 10/12 which is incorrect
8/16 = 1/4 is the same as 8/16 = 4/16 which is incorrect
therefore the only possible answer is 11/15 < 4/15 because:
it is the same as 11/15 < 12/15 which is CORRECT

4) How many solutions does the system of linearequations have?2x + 3y = 6-8x - 12y = -20image
Answer
Explanation
To know how many solutions this system of linear equations have, we willl need to solve it.
2x + 3y = 6
-8x - 12y = -20
Making x the subject of formula in the first equation
2x + 3y = 6
2x = -3y + 6
Divide through by 2
(2x/2) = (-3y/2) + (6/2)
x = (-3y/2) + 3
Substituting this for x in the second equation
-8x - 12y = -20
x = (-3y/2) + 3
-8 (-3
7x - 2xy + 9xy - 2x + 5Like terms
we have given Question is 7x-2xy+9xy+5
now we will rearrange it to like terms
7x-2x+9xy-2xy+5
we use simple addition and subtraction for like terms
5x+7xy+5
so here is the answer
5x+7xy+5
we can write it as below
5+5x+7xy=0

Generally when a coordinate (x , y) is rotated 180 degrees about the origin, it becomes (-x , -y).
Now, the coordinates of the vertices of the triangle will follow a similar transformation when the triangle is rotated 180 degrees about the origin, as follows:

We have this as;
[tex]\begin{gathered} \frac{x-5}{x+5}\text{ = }\frac{7.5}{12.5} \\ \\ 12.5(x-5)\text{ = 7.5(x+5)} \\ 12.5x\text{ - 62.5 = 7.5x + 37.5} \\ 12.5x\text{ - 7.5x = 37.5 + 62.5} \\ 5x\text{ = 100} \\ x\text{ = }\frac{100}{5} \\ \text{ x = 20} \end{gathered}[/tex]But ST is x-5
Simply substitute the value of x in the expression

Solution
The area of a circle with diameter d is

Determine the check digit (d) for the UPC bar code number 2-91273-05213-d. Show your work?
the given UPC bar code digit is
2- 91273 - 05213 - d
for determining d we will follow the rule
first, we sum up all the odd place numbers
like
2 + 1 + 7 + 0 +2 + 3 = 15
then multiply with 3
15 * 3 = 45
then
we sum up all the even place numbers,
9 + 2 + 9 +5 + 1 = 26
now we will add these two results
26 + 45 = 71
now we can see that 71 is 9 less than the next multiple of 10 that is 80 in this case'
80 - 71 = 9
so the answer is
d = 9 .
Fill in the boxes with numbers and operations to reflect the equation of the circle after the transformations
Given the equation of the circle:
[tex]x^2+4x+y^2-12y=-24[/tex]We will complete the squares for x and y to write the equation of the circle as:
[tex](x-h)^2+(y-k)^2=r^2[/tex]Where (h,k) is the coordinates of the circle and r is the radius of the circle
so, the equation will be:
[tex]\begin{gathered} (x^2+4x+4)+(y^2-12y+36)=-24+4+36 \\ \\ (x+2)^2+(y-6)^2=16 \\ \\ (x+2)^2+(y-6)^2=4^2 \end{gathered}[/tex]So, the radius of the circle = 4
And the center of the circle = ( -2, 6 )
Now, we will make the transformation for the circle:
Shift 1 unit up, the center will be = ( -2, 7 )
shift 2 units right, the center will be = ( 0, 7 )
Reflection across the x-axis, the center will be = ( 0, -7)
So, the equation of the circle after transformation will be:

Answer:
[tex]x=\dfrac{1 +\sqrt{673}}{24}, \quad x=\dfrac{1 -\sqrt{673}}{24}[/tex]
Step-by-step explanation:
Given equation:
[tex]3x( 4x +7 ) + 3( 8 + 2 ) = 11( 2x + 3 ) + 11[/tex]
Distribute the parentheses:
[tex]\implies 12x^2+21x+24+6=22x+33+11[/tex]
[tex]\implies 12x^2+21x+30=22x+44[/tex]
Subtract 22x from both sides:
[tex]\implies 12x^2+21x+30-22x=22x+44-22x[/tex]
[tex]\implies 12x^2-x+30=44[/tex]
Subtract 44 from both sides:
[tex]\implies 12x^2-x+30-44=44-44[/tex]
[tex]\implies 12x^2-x-14=0[/tex]
Use the quadratic formula to solve for x.

The sphere at the right fits snugly inside a cube with 4-in. edges. What is the approximate volume of the space between the sphere and cube?
As given by the question
There are given that the inside edge is 4 in.
Now,
Since sphere fits snugly inside a cube therefore diameter of sphere will be equal to side of the cube
So,
[tex]\begin{gathered} \text{diameter}=4\text{ inches} \\ \text{radius}=\frac{dameter}{2} \\ \text{radius}=\frac{4}{2} \\ \text{radius}=2 \end{gathered}[/tex]Then,
Volume of the sphere is given by:
[tex]\begin{gathered} \frac{4}{3}\times\pi\times r^3=\frac{4}{3}\times3.14\times2^3 \\ =\frac{4}{3}\times3.14\times8 \\ =33.5 \end{gathered}[/tex]And,
The volume of a cube is:
[tex]\begin{gathered} \text{Volume of cube=side}\times side\times side \\ =4\times4\times4 \\ =64\text{ inches} \end{gathered}[/tex]Then,
The volume of the space between the sphere and cube = 64-33.5 = 30.5.
Hence, the answer is 30.5 cube inches.
