Consider the numbers 0, 10, 20, 30, and 40. Multiply each by 4 and compare the result to 60 to determine into which of the follo
olya-2409 [2.1K]

Answer:

b) 10 to 20

Step-by-step explanation:

You have to multiply each of the given numbers by 4, and add 8 to that result.

So:

  • 0*4+8  = 8
  • 10*4+8 = 48
  • 20*4+8 = 88
  • 30*4+8 = 128
  • 40*4+8 = 168

And 60 is between the result of <u>10 and 20</u>, so that's the interval you have to select.

<em>The correct answer is b) 10 to 20</em>

Write an expression that represents "the sum of x and 8". x - 8 8x x + 8
Alexxx [7]

<u>Answer:</u>

The expression that represents "the sum of x and 8" is x + 8

<u>Solution:</u>

Given, a sentence “the sum of x and 8”

Now, we have to write an expression that represents the above given line and check the correct option.

So, now, let us take the given expression and convert it into the polynomial form.

Take, “the sum of x and 8" → sum of x and 8 → x + 8.

Here "+" denotes sum or addition.

Hence, expression for “the sum of x and 8” is x + 8 and option c is correct.

15 students were asked how many hours per week they listen to music. 3 different graphs were used to record the same data.
AlladinOne [14]
If you observe the 4 graphical representations you will see that except stem and leaf plot, the rest 3 represent the same information. 

As the time is increasing, the frequency of students who listen to music is decreasing. The frequency is maximum for the first group 0 - 1 and least for the last group 6 - 7.

The ranges shown in both Frequency Table and Histogram are the same. 

So, the following options are correct:
<span>B) One of the displays does not show the same information as the others.
C) The first three displays show that as time increases, frequency decreases.</span>

Answer:

\boxed{\stackrel{\Large\frown}{PQS}\:= 222°}

Explanation:

Since \overline{PR} is a diameter, arc \stackrel{\Large\frown}{PQR}\:= 180°.

Given that \angle{SUR} = 42° is a subtended central angle by two diameters,

\stackrel{\large\frown}{RS} \:= 42°.

Using the rule of arcs, \stackrel{\Large\frown}{PQR} + \stackrel{\large\frown}{RS} \: = \: \stackrel{\Large\frown}{PQS} →

180° + \: 42° = \: \stackrel{\Large\frown}{PQS}

222° = \: \stackrel{\Large\frown}{PQS}

\stackrel{\Large\frown}{PQS} \: = \: 222°
