Answer: 5 and 5/8

Step-by-step explanation: To write an improper fraction as

a mixed number, we divide the denominator into the numerator.

So in this problem, we divide 8 into 45.

8 divides into 45 five times with a remainder of 5.

Also, the denominator of the improper fraction

will become the denominator of the mixed number.

So we have 5 and 5/8

The fraction 45/8 is equal to the mixed fraction 5 5/8.

To convert the fraction 45/8 into a mixed fraction, follow these steps:

Step 1: Divide the numerator (45) by the denominator (8) to determine the whole number part of the mixed fraction.

45 ÷ 8 = 5 with a remainder of 5

Step 2: The quotient obtained in Step 1, 5, represents the whole number part of the mixed fraction. The remainder, 5, becomes the new numerator.

Step 3: Write the mixed fraction using the whole number, numerator, and denominator.

The mixed fraction is 5 5/8.

Answer:

55 days

Step-by-step explanation:

Given

Jim ran 15 miles in 5 days

no. of miles ran in 5 days = 15 miles

dividing LHS and RHS by 5

no. of miles ran in 5/5(=1) days = 15/5 miles = 3 miles

no. of miles ran in 1 day =  3 miles

let the no. of days taken to run 165 miles be x   ----A

No of miles ran in x days = x*no. of miles ran in 1 day = 3x miles

thus,  From A

3x  = 165

x = 165/3 = 55

Thus, it took 55 days for JIM to run 165 miles

Step-by-step explanation:

Answer:

The correct answer to this question is 1200 feet

Step-by-step :

If you're starting at -150, It would take exactly 1200 feet to go from -150 feet to 1350 feet . Here's your answer : Tina hiked 1200 feet to reach the top of the mountain

Answer:

We have the function y = k(x).

We want to define a new function p(x), such that is equal to k(x) but translated down 3 units.

When we have a general case of a function y = f(x), the function g(x) = f(x) + A is a translation of A units up (if A is positive) or A units down (if A is negative).

Then if we want to go 3 units up, we should have:

p(x) = k(x) + 3.

So now our points are:

(x, y) = (x, p(x)) = (x, k(x) + 3)

So for all the points the y-coordinate has ben mooved 3 units up.

See explanation

Step-by-step explanation:

Total number of letters = n! = 10

Permutation for 10 letters = n!

                                          = 10!

                                          = 10*9*8*7*6*5*4*3*2*1

                                          = 3628800

From n letters:

Number of A = 2

Number of C = 2

Number of  L = 2

A₁, A₂, C₁, C₂, L₁, L₂, O, R, T, U

Out of 3628800 permutations the word calculator can be spelled as:

C₁ A₁ L₁ C₂ U L₂ A₂ T O R

C₂ A₂ L₂ C₁ U L₁ A₁ T O R

and so on

So total number of different permutations are  

(permutation of number of letters) / permutation of (number of As * number of Cs * number of Ls)

  =  10! / (2! 2! 2 !)  

  = 10*9*8*7*6*5*4*3*2*1 / (2*1) (2*1) (2*1)

  = 3628800 / 2 * 2 * 2

  =  3628800 / 8

  =   453600

Hence probability that a randomly selected permutation of the letters A, A, C, C, L, L, O, R, T, U would spell "calculator" is:

 1 / total number of different permutations  

= 1 / 10! / (2! 2! 2 !)  

= 1/453600

= 0.000002

Answer:

[tex]\frac{1}{9}[/tex]

Step-by-step explanation:

Create 2 equations with the repeating part after the decimal point. Then by subtracting the repeating part is eliminated

let x = 0.1111.... → (1) ← multiply both sides by 10

10x = 1.1111.... → (2)

Subtract (1) from (2) eliminating the repeater, that is

9x = 1 ( divide both sides by 9 )

x = [tex]\frac{1}{9}[/tex]

That is

0.111111... = [tex]\frac{1}{9}[/tex]

Answer:

  v ≈ (3.28512, 20.74146)

Step-by-step explanation:

  v = 21(cos(81°), sin(81°))

  v ≈ (3.28512, 20.74146) . . . . (x, y) components

The notation varies among authors. The vector can be written as ...

  (r, θ) = (21, 81°)

  r∠θ = 21∠81°

  r cis θ = 21 cis 81°

  v = 21·e^(i·9π/20)

  (x, y) ≈ (3.28512, 20.74146)

  v =  3.28512i +20.74146j . . . . perhaps this is the vector notation you want (i and j are unit vectors in the x- and y-directions, respectively)

Answer:

EF = 34

Step-by-step explanation:

EF + FG = EG , substitute values

17x + 3x + 7 = 18x + 11, that is

20x + 7 = 18x + 11 ( subtract 18x from both sides )

2x + 7 = 11 ( subtract 7 from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

Thus

EF = 17x = 17(2) = 34

Answer:

34

Step-by-step explanation:

g First, you need to find the value of x. To do this you need to add the lengths of EF and FG and set it equal to the total length of EG, then solve.

EF=17x, FG= 3x+7, EG = 18x+11

17x+3x+7=18x+11

Combine like terms.

20x+7=18x+11

-7          -18x

Isolate x.

2x = 4

Divide both sides by 2.

x=2

Now that we have the value for x, we need to plug it into the length of EF to find the numerical value.

17x = 17(2) = 34

Answer:

6

Step-by-step explanation:

Answer:

The correct answer is x = 2.

Step-by-step explanation:

To solve this problem, we should first remember that in solving equations, our goal is to get the variable (in this case, x) by itself on one side of the equation.  To do this, we must divide both sides of the equation by 9 to get rid of the coefficient on the x term.  This is modeled below:

9x = 18

9x/9 = 18/9

x = 2

Therefore, the correct answer is x = 2.

To check your answer, you can always plug the value for x back into the equation.  For example, 9(2) = 18 is a true statement, so we know that we got the correct answer.

Hope this helps!

The value of x from the equation 9x = 18 is x= 2.

To find the value of x in the equation 9x = 18, we need to isolate x on one side of the equation.

To do that, we can divide both sides of the equation by 9:

(9x) / 9 = 18 / 9

Simplifying:

x = 2

Therefore, the value of x is 2.

We can also say that,

By dividing both sides of the equation by 9, we determined that when x is multiplied by 9, it equals 18, so x must be 2 in order for the equation to be true.
