Pre image ABCD was dilated to be image A’B’C’D, where the center of dilation is the origin. What scale factor was used in the di
ArbitrLikvidat [17]

Answer:

The scale factor is 0.25

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

ABCD and A'B'C'D' are similar

therefore

\frac{A'B'}{AB}=\frac{B'C'}{BC}=\frac{C'D'}{CD}=\frac{A'D'}{AD}

Find the scale factor

Looking at the graph

we have

A'B'=1\ unit\\AB=4\ units

Let

z ---> the scale factor

z=\frac{A'B'}{AB}

substitute the values

z=\frac{1'}{4}=0.25

On a single roll of two number cubes, what is the probability of rolling doubles given that the sum is 6
dexar [7]

Answer:

1/6

Step-by-step explanation:

We can make a Punnett square to find number of favourable outcome

so

            cube1

         +

cube2    1          2          3        4          5         6

1            2         3           4        5          6        7      

2            3         4           5        6          7         8    

3            4          5         6        7         8         9

4           5          6          7         8         9         10

5         6           7          8         9        10         11

6           7           8          9         10        11         12

The probability of rolling doubles given that the sum is 6

<h3> favourable outcome / number of outcome</h3>

 6 / 36

  1 / 6

Kisachek [45]

Answer:


Step-by-step explanation:

first your going to do the least common multiple which is 12 for both then your going to subtract because were trying to find out how many students did there work correctly. so, whatever you do to the denominator you do to the numerator so, its going to be 10/12 - 9/12= 1/12 is your answer.

Suppose that y is directly proportional to x and that y = 10 when x = 3. Complete parts (a) and (b). (a) Find the constant of pr
Yuliya22 [10]

For this case we have that if "y" varies directly with "x", then it is true that:

y = kx

Where:

k: It is the constant of proportionality

We have according to the data that:

10 = k (3)

We find the value of "k":

k = \frac {10} {3}

Having "k", we find "y" when x = 6:

y = \frac {10} {3} (6)\\y = \frac {60} {3}\\y = 20

ANswer:

k = \frac {10} {3}\\y = 20
