The expression

swat32

Answer:

The expression

1/4

is given. Give a real-life application to explain this expression and then simplify it.

Given a life expression to solve this, when one divide 100 pieces of pencil by 25 which is 1/4 of the entire pencil.

1/1/4=1 x 4/1

Step-by-step explanation:

divide 1 by 1 over 4, then using cross multiply

then we have 1 multiply 4 divided by 1

4 is the final answer

Which transformations of RST will result in the same image? Check all that apply.

Lelechka [254]

Answer:

I think sentences 1 and 2

Step-by-step explanation:

If triangle translated 2 units left, (x,y)-----(x-2,y)

and then reflected over the y-axis, (x-2,y)-----(-x+2,y)

The relation between image and pilgrimage is (x,y)-----(-x+2,y)

The vertices of image are S(-4,4),T(-1,4), R(-1,1)-----S'(6,4),T'(3,4), R'(3,1)

Therefore the vertices of image are S'(6,4),T'(3,4), R'(3,1).

1. A reflection over the y-axis and then a translation 2 units right is defined as (x,y)-----(-x+2,y)

It is equivalent to relation 1, therefore option 1 is correct.

2. A 180 rotation about the origin, then a translation 2 units right, and then a reflection over the x-axis is defined as (x,y)-----(-x+2,y)

It is equivalent to relation 1, therefore option 2 is correct.

3. A reflection over the y-axis and then a translation 2 units left is defined as (x,y)-----(-x-2,y)

It is not equivalent to relation 1, therefore option 3 is incorrect.

4. A 180 rotation about the origin, then a translation 2 units left, and then a reflection over the x-axis is defined as (x,y)-----(-x-2,y)

It is not equivalent to relation 1, therefore option 4 is incorrect.

5. A reflection over the x-axis and then a translation 2 units right is defined as (x,y)-----(x+2,-y)

It is not equivalent to relation 1, therefore option 5 is incorrect.]

6. A reflection over the x-axis and then a translation 2 units left is defined as (x,y)-----(x+2,-y)

It is not equivalent to relation 1, therefore option 6 is incorrect.

So for that reason im pretty sure the correct options are 1 and 2.

Let’s write the possible subsets of the following sets and list the proper subsets separately

Arisa [49]

Step-by-step explanation:

(a) subsets are {apple}, { }

(b) subsets are {1}, {2}, {1,2}, { }

proper subsets are {1}, {2}

{a}, {b}, {c}, {a,b}, {a,c}, {b,c}, {a,b,c}, { }

proper subsets are {a}, {b}, {c}, {a,b}, {a,c}, {b,c}

(d) subsets are {1},{2},{3},{4},{1,2},{1,3},{1,4},{2,3},{2,4},{3,4},{1,2,3},{1,2,4},{1,3,4},{2,3,4},{1,2,3,4},{ }

proper subsets are {1},{2},{3},{4},{1,2},{1,3},{1,4},{2,3},{2,4},{3,4},{1,2,3},{1,2,4},{1,3,4},{2,3,4}
