In triangle LMN, LM = 6, MN = 9, and LN = 7. Find m∠M to the nearest tenth of a degree. A. 50.0 degrees B. 41.8 degrees C. 45.5 degrees D. 87.3 degrees Please help I need it as soon as possible! Thank you

Answers

Answer 1

Answer:

A. 50.0 degrees

Step-by-step explanation:

In a triangle LMN, we are given te following;

LM = 6

MN = 9

LN = 7

To get the angle m<M, we will use the cosine rule

LN² = LM²+MN² - 2(LM)(MN)cosm<M

7² = 6²+9²-2(6)(9)cosm<M

49 = 36+81-108cosm<M

49 = 117-108cosm<M

49 - 117 = -108cosm<M

-68 = -108cosm<M

cosm<M = -68/-108

cosm<M = 17/27

cosm<M = 0.6296

m<M = cos^-1(0.6296)

m<M  = 50.97

Hence the required angle to nearest tenth is 50.0 degrees

What is Circle geometry?

The sum of the opposite angle of the quadrilateral within the circle is 360 degrees.

Given the following parameters

<B = 3x - 4

<D = 2x - 6

Equate both equations

<B + <D = 180

3x - 4 + 2x - 6 = 180

5x - 10 = 180

5x = 190

x = 190/5

x = 38

Determine the measure of <B and <D

<B = 3x - 4 = 3(38) - 4

<B = 110 degrees

<D = 2x - 6

<D = 2(38) - 6

<D = 76 - 6

<D = 70 degrees

Hence the measure of <B and <D are 110 degrees and 70 degrees

B The zeros are - and 1, because f(x) = (x - 1)(2x + 5).
2
C The zeros are -1 and, because f(x) = (x + 1)(2x-5).
The zeros are 1 and, because f(x) = (x - 1)(2x - 5).

Answers

9514 1404 393

Answer:

  C.  The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).

Step-by-step explanation:

The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.

The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.

Additionally, the x-term needs to match the result of multiplying out the factors.

  B.  (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)

  C.  (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)

The factors of C are zero when x=-1, x=5/2.

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adults.The receipts for admission totaled to $1249.50. How many children and how many adults swam at the public pool that day?

Answers

Answer:

120 children and 388 adults bought tickets for the swimming pool

Explanation:

Create two simultanous equations:

Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being

c

+

a

=

508

then, you now create a second equation for the prices of the tickets.

(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected

so:

1.75

c

+

2.25

a

=

1083.00

now we still know, that

a

=

508

c

so we can substitute it into the second formula

1.75

c

+

2.25

(

508

c

)

=

1083

now its just simple algebra

1.75

c

+

1143

2.25

c

=

1083

60

=

0.5

c

so:

c

=

120

now we know, that 120 children went to the swimming pool.

and we still have the formula from before:

a

=

508

c

so

a

=

388

There is 75% of a pizza and there are 3 siblings who want to eat it for lunch. They divide what they have of the pizza evenly among themselves. In terms of a whole pizza, what percent did each sibling get.

This question would mean dividing 75% or .75 by 3 which would mean each person got 25% or .25 of what would be a whole pizza.
So while each person would get .33 of the current sized pizza (.75) in terms of a whole pizza it would be .25

THREE expressions equivalent to –81x+27.

Answers

Hey there!

One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us [tex]\frac{-81x+27}{3}[/tex]. If we simplify this, we get [tex]-27x+9[/tex].

Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us [tex]\frac{-81x+27}{21}[/tex]. If we simplify this, we get [tex]-3x+1[/tex].

One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us [tex]1(-81x+27)+0[/tex].
