Answer:

Any irrational number is added to 0.4 it will give an irrational number.

Step-by-step explanation:

We need to tell the number which produces an irrational number when added to 0.4.

An irrational number is a number which cannot be expressed in the form of fraction $\frac{x}{y}$ . In other words we can put that decimal expansion of an irrational number does not terminate or cease to end.

Now, if any irrational number is added to 0.4 it will give an irrational number.

Some examples could be: $\sqrt2, \sqrt3, \pi$ and any non-terminating number.

Tak purchased 4 7/8 pounds of brown sugar. Each pound of the sugar equals 2 1/4 cups. What is the best estimate of the number of

ki77a [65]

Answer:

7 1/8

4 + 7/8 + 2 + 1/4

4+2=6

7/8 + 1/4=9/8 and 9/8 is equal to 1 1/8

6+1+1/8= 7 1/8

Help<br> 12-20. PLEASE SHOW YOUR WORK!!<br> Homework is due tomorrow.

Digiron [165]

Answer:

12.)-5

13.)-16

14)-20

15)6

16)-13

17)1

18)-13

19)15

20)-10

Step-by-step explanation:

12.)-x=2+3

x=5/-1

so,x=-5

13.)-4=(-2×8+x)/8

-4×8=-16+x

-32+16=x

so,x=-16

14)(7×4+m)/4=2

28+m=8

so,m=-20

15)4n=34-10

n=24/4

so,n=6

16)-2a=22+4

a=26/-2

so,a=-13

17)a+3=2×2

a=4-3

so,a=1

18)-133+3=10x

-130=10x

so,x=-13

19)4+1=v/3

5*3=v

so,v=15

20)1=3+r/5

now,

Take LCM,

We get,

1=(3*5+r*1)/5

now,

by moving 5 into LHS

We get,

1*5=15+r

5=15+r

by moving 15 into left hand side,

We get ,

5-15=r

so,r=-10 because when we subtract smaller from bigger we have to take the sign of bigger.

quadrilateral WXYZ is reflected across the line y=x to create quadrilateral W’X’Y’Z'. What are the coordinates of quadrilateral

rosijanka [135]

Explanation

We are required to determine the coordinates of W’X’Y’Z' when WXYZ is reflected across the line y = x.

This is achieved thus:

From the image, we can deduce the following:

$\begin{gathered} W(-7,3) \\ X(-5,6) \\ Y(-3,7) \\ Z(-2,3) \end{gathered}$

We know that the following reflection rules exist:

Therefore, we have:

$\begin{gathered} (x,y)\to(y,x) \\ W(-7,3)\to W^{\prime}(3,-7) \\ X(-5,6)\to X^{\prime}(6,-5) \\ Y(-3,7)\to Y^{\prime}(7,-3) \\ Z(-2,3)\to Z^{\prime}(3,-2) \end{gathered}$

Hence, the answers are:

$\begin{gathered} \begin{equation*} W^{\prime}(3,-7) \end{equation*} \\ \begin{equation*} X^{\prime}(6,-5) \end{equation*} \\ \begin{equation*} Y^{\prime}(7,-3) \end{equation*} \\ \begin{equation*} Z^{\prime}(3,-2) \end{equation*} \end{gathered}$

This is shown in the graph bwlow for further undertanding:
