Answer:

Angle YZX = 19.7 degrees

This is the same as saying angle Z = 19.7 degrees

====================================================

Explanation:

Since there are only three letters, and nothing else, we can refer to "angle YZX" as "angle Z" to shorten things. The middle letter is what determines the vertex of the angle.

With Z as the reference angle, side XY = 7.5 is the opposite side. It's the leg furthest from the reference angle. SIde ZY = 22.3 is the hypotenuse. The hypotenuse is always opposite the 90 degree angle.

We'll use the sine rule since it connects the opposite and hypotenuse

sin(angle) = opposite/hypotenuse

sin(Z) = XY/ZY

sin(Z) = 7.5/22.3

sin(Z) = 0.336323

Z = arcsin(0.336323)

Z = 19.653008983888

Z = 19.7

In this case, rounding to 3 sig figs means rounding to 1 decimal place (the first two digits are part of the whole number while the last digit is the decimal portion).

Make sure your calculator is in degree mode. The notation "arcsin" refers to arcsine which is the same as inverse sine. Your calculator would likely have the button [tex]\sin^{-1}[/tex] to indicate inverse sine.

Answer:

Degrees: 19.7

Radians: 0.343

Step-by-step explanation:

First, let x = angle YZX.

You can solve this using sine (which as a reminder, is opposite over hypotenuse):

sin(x) = 7.5/22.3

x = arcsin(7.5/22.3)

Now you can grab out a calculator and evaluate.

If it's in degrees: 19.7

If it's in radians: 0.343

(Remember to round to 3 significant figures like the problem said)

I hope this helped you.

Answer:

28.5 equals ab 29 bracelets

Step-by-step explanation:

Answer:

29 bracelets

Step-by-step explanation:

The first thing you (always) need to do is highlight important details. Some things you should highlight are: The entry fee is $150, He makes $4 off of each bracelet, and that he has $36 so far. We know that 4 times 10 is 40. if we add 40+ the 36, we get 76. now we need 74 more dollars, so let's do: 74 divided by 4 = 18.5. since we can't do that, we add one more bracelet to make it 19. This makes sure we get enough money for the fee. All we have to do now is add is together. 10+19= 29 bracelets

The correct answer is C. 28x – 56 = 84

Explanation:

Writing an equation using a description or situation involves including all the factors mentioned and relating these appropriately through mathematical symbols. In the case presented, the correct equation is 56 – 28x = 84. This is because this equation includes the total of boxes Tony took to the party 84 and this has been correctly included after the symbol =. Also, the total of boxes is equal to the boxes tony bought each with 28 cookies, which can be represented as 28x (x represents the value of boxes that multiplied by 28 leads to the total of cookies) minus the cookies Tony bought (2 boxes each with 28 cookies). This makes the final equation to be 28x – 56 = 84.

Answer:

Answer: Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.

Answer:

.25 pounds

Step-by-step explanation:

Unfortunately, the type of model that is supposed to be used is not given so I will just solve what I can. So each friend gets and equal amount. If we have 1 pound in the beginning, and 4 friends, then we have to divide the candy by 4. So we do 1 pound/4=.25 pounds. If you want to go above and beyond, we can always convert the pounds into ounces and make it so each friend gets 4 ounces of candy.

Answer:

250 Hamburgers

302 cheeseburgers

Step-by-step explanation:

you sold X number of hamburgers

and x+52 number of cheeseburgers

total was 552

make an equation x+x+52=552

so 2x+52=552

now solve for x

x=250

to find cheeseburgers

(250)+52=302

hamburgeres =x=250

Answer:

As both these angles form a linear pair, they together will form 180°

So,

(2x + 45)° + x = 180°

=> 2x + 45 + x = 180°

The  variable are

A and  B

Step-by-step explanation:

Generally we can define a variable as a name of a placeholder representing a value  now considering the option to be selected from we see that

    The students' verbal SAT scores is a variable  because it is a phrase or a place holder that represent a value (in the is case a  numerical value)  which the score its self

    The second option  The students' percentage of words that were correctly recognized on the original list is also a variable because it is a placeholder of a name (in this case a phrase ) that represented the actual value itself

  The  third option The 75 students is not a variable because it is not representing any value but itself is the value

  The  third option The 750 students is not a variable because it is not representing any value but itself is the value

Answer:

-6

Step-by-step explanation:

Let "what" be termed as "x".

Set the equation:

3 * x = -18

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 3 from both sides:

(3x)/3 = (-18)/3

x = -18/3

x = -6*

*Note: When you divide a negative number with a positive number, your answer will be negative.

-6 is your answer.

~

The value of number which is 3 times to -18 is -6 .

Given,

3 *x = -18

So,

Let "what" be termed as "x".

Form the equation including the variable x ,

3 * x = -18

Isolate the variable, x.

Note the equal sign, what you do to one side, you do to the other. Divide 3 from both sides:

(3x)/3 = (-18)/3

x = -18/3

x = -6

-6 is the required answer .

12 1/3

Step-by-step explanation:

Answer:

12 1/3

Step-by-step explanation:

1. Divide the numerator by the denominator.

Divide 37 by 3, which equals 12 with a remainder of 1.

37 ÷ 3 = 12 r1

2. Find the whole number.

The whole number is the number of times the denominator divides into the numerator.

3 (the denominator) divides into 37 (the numerator) 12 times, so 12 is the whole number.

Make the remainder the new numerator.

Because the remainder (the leftover value) of dividing 37 by 3 is 12, 1 is the new numerator. The denominator is still 3. So, the mixed fraction is:

12 1/3

Answer:

The probability is  [tex]P(K)  =   \frac{ 28 }{195} [/tex]

Step-by-step explanation:

From the question we are told that

   The number of green marbles is  [tex]n_g  =  3[/tex]

    The number of red marbles is  [tex]n_b  =  5[/tex]

     The number of red marbles is  [tex]n_r  =  7[/tex]

Generally the total number of marbles is mathematically represented as

       [tex]n_t  =  n_r  +  n_g + n_ b[/tex]

        [tex]n_t  =  7 +  3 + 5[/tex]

         [tex]n_t  = 5 [/tex]

Generally total number of marbles that are not red is  

     [tex]n_k  =  n_g +  n_ b[/tex]

=>  [tex]n_k  =   3 +   5[/tex]

=>  [tex]n_k  =  8[/tex]

The probability of the first ball not being red is mathematically represented as  

      [tex]P(r') =  \frac{n_k}{n_t}[/tex]

=>  [tex]P(r') =  \frac{ 8}{15}[/tex]

The probability of the second ball not being red is mathematically represented as

      [tex]P(r'') =  \frac{n_k - 1}{n_t -1}[/tex]

=>  [tex]P(r'') =  \frac{ 8 -1 }{15-1}[/tex] (the subtraction is because the marbles where selected without replacement  )

=>  [tex]P(r'') =  \frac{ 7 }{14}[/tex]

The probability that the first two balls  is  not red is mathematically represented as

    [tex]P(R) =  P(r') *  P(r'')[/tex]

=>  [tex]P(R) =  \frac{ 8}{15} *   \frac{ 7 }{14}[/tex]

=>  [tex]P(R) =  \frac{ 8 }{30}[/tex]

The probability of the third ball being red is mathematically represented as

   [tex]P(r) =  \frac{n_r}{ n_t -2}[/tex] (the subtraction is because the marbles where selected without replacement  )

     [tex]P(r) =  \frac{7}{ 15 -2}[/tex]

=>    [tex]P(r) =  \frac{7}{ 13}[/tex]

Generally the probability of the first two marble not being red and the third marble being red is mathematically represented as

        [tex]P(K)  =  P(R) * P(r)[/tex]

         [tex]P(K)  =   \frac{ 8 }{30} * \frac{7}{ 13}[/tex]

=>      [tex]P(K)  =   \frac{ 28 }{195} [/tex]
