Answer:

5040°

Step-by-step explanation:

assuming you mean the sum of the interior angles.

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 30 , then

sum = 180° × 28 = 5040°

Answer:

-1/4

Step-by-step explanation:

We use the formula:

Therefore our slope is -1/4

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

Explanation:

Add up the numbers in the second column:

4+19+25+32 = 80

There are 80 people being surveyed in the table.

Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.

The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5

----------

Multiply this probability with the larger sample size of 300 to get

(2/5)*300 = 0.4*300 = 120

We estimate that 120 people would exercise for more than 136 minutes.

Note that 120/300 = 2/5.

Step-by-step explanation:

Usando un sistema de ecuaciones vamos a ver que entran 24 libros de letras en el estante.

Vamos a usar las variables:

Por el texto, podemos saber que el peso maximo que tolera el estante esta dado por el sistema de ecuaciones.

30*x + 6*y = P

10*x + 18*y = P

Podemos igualar esas dos ecuaciones para obtener:

30x + 6y = 10x + 18y

30x - 10x = 18y - 6y

20x = 12y

x = (12/20)*y

Ahora, podemos reemplazar esto en una de las dos ecuaciones, por ejemplo la primera:

30x + 6y = P

30*(12/20)y + 6y = P

(3/2)*12*y + 6y = P

18y + 6y = P

24y = P

Así concluimos que entran 24 libros de letras en el estante.

Answer:

77.4 degrees and 12.6 degrees

Step-by-step explanation:

Let the angles be x and x - 64.8.

Therefore, on the basis of knowledge that complementary angles add up to 90 degrees :

x + x - 64.8 = 90

2x = 154.8

x =  77.4 degrees

x - 64.8 = 77.4 - 64.8 = 12.6 degrees

her score was in the top 85% of all test takers' scores.

Step-by-step explanation:

Percentile is the relative standing in a set of data from the lowest values to highest values.

If your score is in the 85th percentile, it means that 85% of the scores are below your score and 15% are above your score.

Answer:

A. Her score was better than those of 85% of all test takers.

Answer:

E

Step-by-step explanation:

"S" stands for "side" and "A" stands for "angle"

SAS = side angle side

The order is important because the angles must be between the two congruent sides.

One pair of congruent sides is AC = CE as shown by the single tickmarks.

The other pair of congruent sides is BC = CD shown by the double tickmarks

The congruent angles are the vertical angles BCA and DCE. Vertical angles are always congruent. Note how these angles are sandwiched between the tickmarked sides.

Answer:

A

Step-by-step explanation:

We have the graph of the function f(x).

We want to determine which of the given is true of the graph from [tex]x=g[/tex] to [tex]x=\infty[/tex].

So, essentially, we are focusing on the last curve (see image below).

First, since the curve is above the x-axis, the curve is positive.

Second, since the curve is curving upwards, this means that it must be increasing. Another way to think about this is to think about the slope of our curve. While we can't calculate the exact slope, the average slope will be positive, so our function is increasing.

So, our answer is A.

And we're done!

What is the decimal equivalent to -3 3/12

[tex]\huge\rm{ANSWER:}[/tex]

[tex]\huge\rm{SOLUTION:}[/tex]

To begin, keep in mind that - 3 3/12 is a mixed number, also known as a mixed fraction. It has a valid fraction as well as a complete number.

The following is a list of the numbers in a mixed fraction:

[tex]\huge \rm{ - 3}[/tex] the whole number.

[tex]\huge \rm{ 3}[/tex] the numerator

[tex]\huge \rm{ 12}[/tex] the denominator

Follow these procedures to convert -3 3/12 from a mixed number to a decimal number:

Divide the denominator by the numerator to convert the correct fraction to decimal.

3 ÷ 12 = 0.25

To get the entire number of the mixed fraction, multiply it by this decimal number.

-3 + 0.25 = - 3.25

Therefore, the decimal equivalent to -3 3/12 is -3.25
