Answer:

1) x= 35 , y = 18

2) x = 20 , y = 23.33

3) x = 11

4) x = 9

5) x = 10

Step-by-step explanation:

1)As the triangles are similar, here the ratio is as;

\frac{JK}{NM} = \frac{KL}{ML}  = \frac{LJ}{LN}

 \frac{40}{16} = \frac{x}{14}  = \frac{45}{y}

from here, x=35 and y = 18

2)As the triangles are similar, here the ratio is;

\frac{DE}{HJ} = \frac{EF}{JG}  = \frac{FD}{GH}

 \frac{9}{15} = \frac{14}{y}  = \frac{12}{x}

from here, x=20 and y= 23.33

3)As the triangles are similar, here the ratio is;

  \frac{QR}{TU} = \frac{RS}{UV}

  \frac{24}{x +5} = \frac{54}{36} here, x = 114)As the triangles are similar, here the ratio is;    [tex]\frac{AB}{AD} = \frac{BC}{DE}

    \frac{28}{20} = \frac{2x+3}{15}

here, x = 9

5)As the triangles are similar, here the ratio is;

\frac{NP}{RP} = \frac{MP}{QP}

\frac{x+8}{3x-9} = \frac{24}{28},

from here, x = 10

The blades of a windmill turn on an axis that is 35 feet above the ground. The blades are 10 feet long and complete two rotation
Alona [7]

Answer:

h = 10sin(π15t)+35

Step-by-step explanation:

The height of the blade as a function f time can be written in the following way:

h = Asin(xt) + B, where:

B represets the initial height of the blade above the ground.

A represents the amplitud of length of the blade.

x represents the period.

The initial height is 35 ft, therefore, B = 35ft.

The amplotud of lenth of the blade is 10ft, therefore A = 10.

The period is two rotations every minute, therefore the period should be 60/4 = 15. Then x = 15π

Finally the equation that can be used to model h is:

h = 10sin(π15t)+35

in chemistry class Andrew has earned scores of 64 69 and 73 on three tests he must maintain an average of 72
olganol [36]
You haven't told me what the question is.  But I put the mouse
to my forehead, closed my eyes, took a deep breath, and I could
see it shimmering in my mind's eye.  It was quite fuzzy, but I think
the question is

                   "What score does Andrew need on the next test
                     in order to raise his average to 72% ?"

The whole experience drew an incredible amount of energy
out of me, and the mouse is a total wreck.  So we'll just go ahead
and answer that one.  I hope it's the correct question.

The average score on 4 tests is

                                     (1/4) (the sum of all the scores) .

In order for Andrew to have a 72% average on 4 tests,
the sum of the 4 scores must be

                                         (4) x (72%)  =  288% .

Out of that total that he needs, he already has 

                            (64% + 69% + 73%) = 206%

on the first three tests.

So in order to average 72% for all 4 tests,
he'll need to score

                             (288%  -  206%)  =   82%

on the fourth one.
