Is 5 a rational number

Answer:

a

Step-by-step explanation:

14x+42=35

14×=35-42

14× = -7

×= -7/14

×= -1/2

Answer:

A

Step-by-step explanation:

Given f(x) = 14x + 42 and f(x) = 35, then equate right sides, that is

14x + 42 = 35 ( subtract 42 from both sides )

14x = - 7 ( divide both sides by 14 )

x = - [tex]\frac{7}{14}[/tex] = - [tex]\frac{1}{2}[/tex] → A

Answer: the answer  is 3/48

We can write "3/4 divided by 12" as a fraction as 1/15.

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. Division helps to split a given number into equal parts.

Given is to find -

"3/4 divided by 12" as a fraction.

We can write - "3/4 divided by 12" as a fraction -

{x} = 3/4 ÷ 12

{x} = 3/4 x 1/12

{x} = 3/48

{x} = 1/15

Answer:

Pi is approximately 3.14 in decimal form and [tex]\frac{22}{7}[/tex] in fraction form.  

Answer:

The value of x=9 and value of y= -7

Step-by-step explanation:

We need to solve the matrix equation for x and y

We are given:

[tex]\left[\begin{array}{cc}-2x&6\\1&-8\\\end{array}\right] +2\left[\begin{array}{cc}5&-1\\y&6\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right][/tex]

First multiply 2 with terms inside the matrix

[tex]\left[\begin{array}{cc}-2x&6\\1&-8\\\end{array}\right] +\left[\begin{array}{cc}10&-2\\2y&12\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right][/tex]

Now adding matrices on left side

[tex]\left[\begin{array}{cc}-2x+10&6-2\\1+2y&-8+12\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right]\\\left[\begin{array}{cc}-2x+10&4\\1+2y&4\\\end{array}\right] =\left[\begin{array}{cc}-8&4\\-13&-13\\\end{array}\right][/tex]

Now both sides are equal , so we can say that

[tex]-2x+10=-8 \ and \ 1+2y=-13[/tex]

Solving equations and finding values of x and y

Finding value of x

[tex]-2x+10=-8 \\-2x=-8-10\\-2x=-18\\x=\frac{-18}{-2}\\x=9[/tex]

Finding value of y

[tex]1+2y=-13\\2y=-13-1\\2y=-14\\y=\frac{-14}{2}\\y=-7[/tex]

So, value of x=9 and value of y= -7

Although I replied late, nobody gave the answer.

The answer you are looking for is C). But how do you know it's correct? Do some calculation.

Child bike: 4 hours to build + 4 hours to test = 8 hours total

Adult bike: 6 hours to build + 4 hours to test = 10 hours total

5*4 = 20 build hours for child bikes

5*4 = 20 test hours for child bikes

15*6 = 90 build hours for adult bikes

15*4 = 60 test hours for adult bikes

20 + 20 = 40 total hours for child bikes

90 + 60 = 150 total hours for adult bikes

20 + 60 = 80 total test hours

20 + 90 = 110 build hours

Since this amount is below the maximum, the bike order DOES meet the restrictions.

Our equations should be 4c + 6a ≤ 120 for the total building hours, and 4c + 4a ≤ 100 for the total testing hours.

In conclusion, the answer is C) Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100.

Answer:

D

Step-by-step explanation:

The magnitude is 25 and the direction angle of vector c is 73.7°. Option D is correct.

Given, a=⟨2,10⟩, b=⟨-5,-14⟩, c=a-b

We need to find what is the magnitude and direction angle of vector c.

Given a position vector v=⟨a,b⟩, the magnitude is found by |v|=√a²+b². The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application. For a position vector, the direction is found by tanθ=(ba)⇒θ=[tex]tan^{-1}[/tex](ba).

Now, vector c=⟨7,24⟩|c|=[tex]\sqrt{7^{2} +24^{2} }[/tex]=25angle =tan(θ)=(168)⇒θ=[tex]tan^{-1}[/tex](168)= 73.7°.

Hence, the magnitude is 25 and the direction angle of vector c is 73.7°.

Answer:

The 3 odd, consecutive numbers are 25, 27, and 29.

Step-by-step explanation:

When you add these 3 numbers you will get 81.

25 + 27 = 52

52 + 29 = 81

Therefore, 25 + 27 + 29 = 81

Hope this helps!!

Answer:three consecutive odd numbers are 25; 27; 29

suppose: the smallest number is x ( x > 0),(x ∈ N)

because 3 numbers are three consecutive odd numbers

=> The next 2 terms respectively are x + 2; x + 4

have: The sum of three consecutive odd numbers is 81

=> x + x + 2 + x+ 4 = 81

⇔ 3x + 6 = 81

⇔ 3x = 81 - 6

⇔ 3x = 75

⇔ x = 25

=>  three consecutive odd numbers are 25; 27; 29

Answer:

$32.50

Step-by-step explanation:

To answer this question, find the price per widget by dividing $7.50 by the number of widgets (12)

7.50 / 12 = 0.625

You may be tempted to round to 0.63 here, and maybe that is what your teacher wants, but typically you save rounding for the end of your calculations. So let's keep the price-per-widget at 0.625 and multiply it by the 52 widgets to find the total cost.

0.625 * 52 = 32.5 or $32.50
