Answer:

7/60

Step-by-step explanation:

Here is the full question

Diana works at a clothing store. She sold 1/5 of the total number of green shirts on Monday and 3/12 of the total number of green shirts on Tuesday. What fraction of green shirts did Diana sell on Monday and Tuesday? 27/60 is the answer. Diana sold 2/15 of the total number of green shirts on Wednesday. What is the difference in the fraction of the total number of green shirts that were sold on Tuesday and Wednesday?

fraction of green shirts did Diana sell on Monday and Tuesday =

\frac{1}{5} + \frac{3}{12}

\frac{12 + 15}{60} = \frac{27}{60}

difference in the fraction of the total number of green shirts that were sold on Tuesday and Wednesday =

\frac{3}{12} - \frac{2}{15} =\\\frac{15 - 8}{60} \\\frac{7}{60}

Find the Length of ST
vfiekz [6]

Step-by-step explanation:

Consider Similarity and enlargement

To get the enlargement factor,

Take the ratio result of any two similar sides. i.e

PQ/AB = 3.6/2 = 1.8

The enlargement factor is 1.8

To get ST, consider ED then multiply it by the enlargement factor. i.e

= 5 x 1.8

= 9

Help please? Suppose you have a normally distributed set of data pertaining to a standardized test. The mean score is 500 and th
Lina20 [59]
The formula to calculate the z-score of a certain value is:

z = (x - (mean))/(standard deviation)

In this example, the x-value is 450, the S.D. is 100, and the mean is 500.

So, substitute these values into the formula.

z = (450-(500))/100
z=-50/100
z=-0.5

Therefore, the z-score is -0.5.

in the figure below trianglePQM and triangleQRP are right triangles. the measure of lineQM is 6 and the measure of lineQP is 8.
Kipish [7]

Answer:

Option 4 is correct. The length of PR is 6.4 units.

Step-by-step explanation:

From the given figure it is noticed that the triangle PQR and triangle MQR.

Let the length of PR be x.

Pythagoras formula

hypotenuse^2=base^2+perpendicular^2

Use pythagoras formula for triangle PQM.

PM^2=QM^2+PQ^2

PM^2=(6)^2+(8)^2

PM^2=36+64

PM^2=100

PM=10

The value of PM is 10. The length of PR is x, so the length of MR is (10-x).

Use pythagoras formula for triangle PQR.

PQ^2=QR^2+PR^2

(8)^2=QR^2+x^2

64-x^2=QR^2                   .....(1)

Use pythagoras formula for triangle MQR.

MQ^2=QR^2+MR^2

(6)^2=QR^2+(10-x)^2

36=QR^2+x^2-20x+100

36-x^2+20x-100=QR^2        .... (2)

From equation (1) and (2) we get

36-x^2+20x-100=64-x^2

20x-64=64

20x=128

x=6.4

Therefore length of PR is 6.4 units and option 4 is correct.

Solve this problem and show all the step involved.If ad=12and ac=ay_36, find the value of y.Then find ac and DC
pochemuha

Answer:

y = 15

AC = 24

DC = 12

Step-by-step explanation:

Given

AD = 12

AC = 4y - 36

See attachment

Solving for y

From the attachment:

AD = DC

and

AC = AD + DC

Substitute DC for AD

AC = AD + AD

AC = 2AD

Substitute values for AD and AC

4y - 36= 2*12

4y - 36= 24

Collect Like Terms

4y = 36+ 24

4y = 60

Solve for y

y = 60/4

y = 15

AC = 4y - 36

AC = 4 * 15 - 36

AC = 24

AD = DC

DC = AD

DC = 12
