3.06 as. a fraction PLEASE HELP​

Answers

Answer:

153/50

Step-by-step explanation:

3.06

Rewriting as

There are two numbers after the decimal so we put the number over 100

306/100

Divide top and bottom by 2

153/50

To write 3.06 as a fraction you have to write 3.06 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

3.06 = 3.06/1 = 30.6/10 = 306/100

And finally we have:

3.06 as a fraction equals 306/100

A. Q1 = 4.6; Q2 = 5.5; Q3 = 5.95
B. Q1 = 4.7; Q2 = 5.5; Q3 = 6
C. Q1 = 4.7; Q2 = 5.5; Q3 = 5.9
D. Q1 = 4.6; Q2 = 5.5; Q3 = 5.92

Answers

Answer:

A. Q1 = 4.6; Q2 = 5.5; Q3 = 5.95

Step-by-step explanation:

Q2 is the median of the data set:

Q2 = 5.5

Q1 is the median of lower half:

Q1 = (4.5 + 4.7)/2 = 4.6

Q3 is the median of upper half:

Q3 = (5.9 + 6)/2 = 5.95

Correct choice is A

Answer:

A.Q1 = 4.6;Q2 = 5.5;Q3 = 5.95

what should be added to 780629 so that the sum is exactly divisible by 493?​

Answers

Answer:

283

Step-by-step explanation:

Given problem is based on divisibilityy,

 = 780629/493

quotient = 1583

remainder = 210

So,Add 283 with remainder (210) to get 493

= 283+210

= 493

There for 283 should be added to 780629 so that the sum is exactly divisible by 493

The problem has come from division .

First divide them

[tex]\\ \sf\longmapsto \dfrac{480629}{493}[/tex]

[tex]\\ \sf\longmapsto Remainder=210[/tex]

[tex]\\ \sf\longmapsto Quiotent=1583[/tex]

Now We have to add x to the remainder by which it will be 493

[tex]\\ \sf\longmapsto x+210=493[/tex]

[tex]\\ \sf\longmapsto x=493-210[/tex]

[tex]\\ \sf\longmapsto x=283[/tex]

Show all work to identify the asymptotes and zero of the function f of x equals 6 x over quantity x squared minus 36.

Answers

Answer:

vertical asymptotes

x=6, x=-6

horizontal asymptotes

y=0

zeros (0,0)

Step-by-step explanation:

f(x) = 6x / ( x^2 - 36)

First factor

f(x) = 6x / ( x-6)(x+6)

Since nothing cancels

The vertical asymptotes are when the denominator goes to zero

x-6 = 0   x+6=0

x=6          x= -6

Since the numerator has a smaller power than the denominator (1 < 2), there is an asymptote at y = 0

To find the zeros, we find where the numerator = 0

6x=0

x=0

We now have

6x - 4 = 2

Add 4 to both sides

6x - 4 + 4 = 2 + 4

6x = 6

Divide both sides by 6

6x/6 = 6/6

x = 1

Answer:

x = 1

Step-by-step explanation:

-2x + 8x + 3 - 7 = 2

Step 1. Combine like terms (by adding -2x + 8x)

6x + 3 - 7 = 2

Step 2. Subtract 3 - 7

6x - 4 = 2

Step 3. Add 4 to both sides

6x = 6

Step 4. Solve for x

If (3a+4b)=16 and ab=4, find the value of (9a^2+16b^2).​

Answers

Answer:

160

Step-by-step explanation:

(3a+4b) = 16

ab = 4

Square (3a+4b)

(3a+4b)(3a+4b) = 16^2

9a^2 + 12ab+12ab+16b^2 = =256

9a^2 +16b^2   +24ab=256

9a^2 +16b^2   +24ab - 24 ab=256 -24ab

9a^2 +16b^2  =256- 24ab

We know ab = 4

9a^2 +16b^2  =256- 24*4

9a^2 +16b^2  =256- 96

9a^2 +16b^2  =160

Answers

9514 1404 393

Answer:

  12.6 rad/s

Step-by-step explanation:

1080 degrees in 1.5 seconds is an angular rate of ...

  (1080°)/(1.5 s) = 720 °/s

There are π radians in each 180°, so this angular speed is ...

  720 °/s = 4×180 °/s = 4×π rad/s ≈ 12.6 rad/s

Sasha's average angular speed is 12.6 rad/s.
