5 hours?

Step-by-step explanation:

normally, two people would cut the time in half, but she takes forever. half of 12 is 6, half or 8 is 4, so 5, right? the medium answer

If the polygon is translated 4 units down and 5 units right, what will the coordinates of the new image be? Use prime notation i

steposvetlana [31]

Using prime notation, the new coordinates after translation are;

<em>New coordinates;</em>

A': (-1, 1)

B': (-1, -2)

C': (3, -2)

D': (3, 2)

From the attached image, we can see that the coordinates are;

A(-6, 5)

B(-6, 2)

C(-2, 2)

D(-2, 6)

Translating the polygon down by x units means the value of the y-coordinates will reduce by 4.

In a similar fashion, translation 5 units to the right means that the x-coordinates would increase by 5.

Applying these translation numbers to our coordinates, we will now have;

A(-6 + 5, 5 - 4)

B(-6 + 5, 2 - 4)

C(-2 + 5, 2 - 4)

D(-2 + 5, 6 - 4)

Simplifying each of them gives us the new coordinates as;

A: (-1, 1)

B: (-1, -2)

C: (3, -2)

D: (3, 2)

Can someone please tell me how to find the value of x.

notsponge [240]

Answer:

2.547 = x

Step-by-step explanation:

tan 23 = x/6 Use this equation to find the value of x

0.4245 = x/6 Multiply both sides by 6

2.547 = x

Find each quotient. Write in simplest form. keep answer as fraction - not decimal

kirill [66]

So we are given the expression:

$\frac{mn^{2}}{4}$ ÷ $\frac{m^{2}n}{8}$

When we divide fractions, we must flip the second term and change the sign to multiplication:

$\frac{mn^{2}}{4} *\frac{8}{m^{2}n}$

And then we multiply across:

$\frac{mn^{2}}{4} *\frac{8}{m^{2}n}= \frac{8mn^{2}}{4m^{2}n}$

Then we can break apart all of the like variables for simplification:

$\frac{8mn^{2}}{4m^{2}n}=\frac{8}{4} * \frac{m}{m^{2}} *\frac{n^{2}}{n}$

When we simplify variables through division, we subtract the exponent of the numerator from the exponent of the denominator. So we then have:

$\frac{8}{4} =2$

$\frac{m}{m^{2}}=m^{-1} =\frac{1}{m}$

$\frac{n^{2}}{n}=n^{1}=\frac{n}{1}$

So then we multiply all of these simplified parts together:

$\frac{2}{1}*\frac{1}{m}*\frac{n}{1} =\frac{2n}{m}$

So now we know that the simplified form of the initial expression is: $\frac{2n}{m}$ .

A box contains two purple marbles nine orange marbles and seven yellow marbles if you pick two without looking what is the proba

maw [93]

Answer:

1/4

Step-by-step explanation:

First, add up the marbles:

2 + 9 + 7 = 18

Multiply by 2 because you pick two:

18 × 2 = 36

Simplify:

9/36 = 3/12 = 1/4

Hope this helped.
