Out of 270 racers who started the marathon, 247 completed the race, 14 gave up, and 9 were disqualified. What percentage did not complete the marathon?

Answer:

The domain would be given by D = {X ≥ 2} X = [2, Z]. Since the variable Z is the number of children in the school. And the 6 children should not survey the same person, it would be Z / 6 for each interviewer.

Step-by-step explanation:

- If the group of children surveys more than 2 classmates, it means that the number with which the survey begins is 12 students.

And since the maximum number of students in the school is given by the variable of Z, then Z is the number with which the domain closes.

The rank would be given by the set of [2, Z]

Z / 6 being the maximum number of children surveyed by 1 interviewer.

The Domain of given function is, [tex]x\geq 2[/tex]

The Domain of function is defined as, all input values for which function is defined.

 The total number of completed survey is given by a function,

                        [tex]s(x)=6x[/tex]

Since, If the group of children surveys more than 2 classmates, it means that the number with which the survey begins is 12 students.

It means value of x is always greater and equal to 2.

                        So that,   [tex]x\geq 2[/tex]

Answer:

Step-by-step explanation:

Question A:

Step 1. The product of 7 and d is = 7d.

Step 2. Then the next part is separated by a comma.

Step 3. This leads to the influence of the idea that 7d is subtracted by 16.

Step 4. This concludes that the answer is 7d - 16.

Question B:

Step 1: The product of 7 concludes that 7 is alone.

Step 2: The separation of and shows that the part after and is together.

Step 3: If it is together, we can conclude it goes in parentheses.

Step 4: If it is in parentheses, it means the number 7 is being distributed.

Step 5: This concludes the answer is 7(d - 16).

PR = 12

Step-by-step explanation:

P-----------Q-----------R----------S

ratio

4:2:1

PS = 14

add the ration = 4 + 2 + 1 = 7

14 / 7 = 2

PQ at 4 x 2 = 8

QR at 2 x 2 = 4

RS at 1 x 2 =  2

              ------------

                   14

PR = PQ + QR

PR = 8 + 4

PR = 12

The length of the line segment PR is 12 units.

A line segment is a subset of a line which has two endpoints.

According to the given question The points P, Q, R and S all lie on the same line segment PS and the ratio of PQ : QR: RS is equal to 4:2:1.

Assuming PQ = 4x, QR = 2x and RS = x.

We know PQ + QR + RS = PS.

∴ 4x + 2x + x = 14.

7x = 14.

x = 2.

PR = PQ + QR.

PR = 4(2) + 2(2).

PR = 8 + 4.

PR = 12.

Answer:

943,281

Step-by-step explanation:

Just move the 3 up a value

If it's in the ten's place, then move it to the hundred's place value.

If it's in the hundred's place, then move it to thousand's place value.

So on and so on...

The number is 943,281.

Place value is the value of each digit in a number. The value of every digit in a number is different based upon its position. A number might have two similar digits but different values, which is decided by the position that the digit holds in the number.

Place value is the value of a digit according to its position in the number such as ones, tens, hundreds, and so on.

For example, the place value of 5 in 3458 is 5 tens, or 50. However, the place value of 5 in 5781 is expressed as 5 thousands or 5,000.

Given:

digit 3 is 10 times as much as the value of the digit 3 in 942381

Here the digit 3 is at hundred place value.

Then, after 10 times the place value be at thousand.

hence, the number would be 943,281.

Complete question is;

Consider the sequence shown: A, E, I … Jorge reasons that the next letter in the sequence is M, since three letters of the alphabet are skipped between each listed letter. Which explains whether Marcy should agree with Jorge’s inductive reasoning?

A. No; the sequence could be listing the vowels in alphabetical order.

B. No; sequences with only three terms are too short to use to find patterns.

C. Yes; this is the only reasonable pattern that can be identified from the terms.

D. Yes; inductive reasoning is a valid method for determining terms of a sequence

Answer:

Options C and D are the correct reasons why Marcy should agree with Jorge.

Step-by-step explanation:

A) It's wrong because the alphabets don't have to be listed in alphabetical order.

B) It's wrong because sequence can take any form. It could be 2 terms used to find patterns. It does not matter.

C) This is correct because after letter A, the next 3 letters which are B, C, D were skipped before E. Also, after E, the next 3 letters were skipped which are E, F, G before I. Thus, it's the only reasonable pattern from the terms to find the next term.

D) Inductive reasoning is based on observing patterns in a sequence, which we can use to decide the next successive terms of such a sequence. Thus, this is true because inductive reasoning is a valid method.

Answer: 5

Step-by-step explanation:

The required value of 3 1/3 divided by 2/3 is 5.

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.

For example 4/2 = 2

We have to determine the value of 3 1/3 divided by 2/3.

As per the question,

⇒ 3 1/3 ÷ 2/3

Convert the mixed numbers to fractions,

⇒ 10/3 ÷ 2/3

⇒ (10/3)/(2/3)

⇒ 10/2

Apply the division operation, and we get

⇒ 5

Thus, the required value of 3 1/3 divided by 2/3 is 5.

Answer:

[tex] 7x - 1 [/tex]

Step-by-step explanation:

Area of the shaded region = area of the large rectangular - area of the small rectangle

Area of rectangle is given as l*w

Area of the large rectangle = [tex] l*w = (x + 5)(x - 1) [/tex]

Expand

[tex] = x(x - 1) +5(x - 1) [/tex]

[tex] = x^2 - x + 5x - 5 [/tex]

Area of large rectangle [tex] = x^2 + 4x - 5 [/tex]

Area of small rectangle = [tex] l*w = (x + 1)(x - 4) [/tex]

[tex] = x(x - 4) +1(x - 4) [/tex]

[tex] = x^2 - 4x + x - 4 [/tex]

Area of small rectangle = [tex] = x^2 - 3x - 4 [/tex]

Area of shaded region = [tex] (x^2 + 4x - 5) - (x^2 - 3x - 4) [/tex]

[tex] = x^2 + 4x - 5 - x^2 + 3x + 4 [/tex]

Collect like terms

[tex] = x^2 - x^2 + 4x + 3x - 5 + 4 [/tex]

[tex]\frac{2log(3)(x)}{2log(3)} = \frac{4}{2log(3)}[/tex]

[tex]x = \frac{4}{2log(3)}[/tex]

using a calculator you can write the answer as a rounded number

Answer:

Step-by-step explanation:

1. Using the addition property of equality, we can add 3 to both sides of the equation. Then it can be rewritten as ...

  7x -3 +3 = -17 +3

  7x = -14

__

2. Using the division property of equality, we can divide both sides of the equation by 7. Then it can be rewritten as ...

  7x/7 = -14/7

  x = -2

_____

Additional comment

Note that we have used these steps to solve the equation, find the value of x that makes it true. We could use different steps to rewrite the equation to almost anything you want:

  7x -3 -95 = -17 -95   ⇒   7x -98 = -112 . . . . . subtract 95 from both sides

  12(7x -98) = 12(-112)   ⇒   84x -1176 = -1344 . . . . multiply both sides by 12

The resulting equation is not helpful for finding a solution, but it is an accurate rewrite of the original equation.
