Answer:

Step-by-step explanation:

let x=1.8888...

 10x=18.8888...

10x-x=18.8888...- 1.8888...

  9x=17

    x=17/9

So 1.8888... is equal to 17/9

Answer:

1,888 is equal [tex]\frac{17}{9}[/tex]

Step-by-step explanation:

x = 1,888...

10x = 18,88...

10x - x = 18,88 - 1,88

9x = 17

x = [tex]\frac{17}{9}[/tex]

Answer:

            No real solution

Step-by-step explanation:

[tex]3x^2-4x+4=0\quad\implies\quad a=3\,,\quad b=-4\,,\quad c=4\\\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4\cdot3\cdot4}}{2\cdot3}=\dfrac{4\pm\sqrt{-32}}{6}[/tex]

There is no solution in real number as it's no real √[-32]

{solutins in complex numbers would be: [tex]x_1=\frac{4+4\sqrt{2}\,i}{6}=\frac{2+2\sqrt{2}\,i}{3}\\ x_2=\frac{2-2\sqrt{2}\,i}{3}[/tex] }

yeah this is just about right

Answer:

67 students voted for the eagle

Step-by-step explanation:

The students at Woodward Elementary voted for a school mascot. The falcon won with 5/8 of the votes and the eagle came second with 1/3 of the remaining votes. If 536 students voted for a mascot, how many students voted for the eagle

Total students who voted = 536

Falcon won with 5/8 of the votes

5/8 of 536

=5/8 × 536

= 2,680/8

= 335 votes

Falcons won with 335 votes

Remaining votes = Total votes - falcons votes

= 536 - 335

= 201 votes

There are 201 votes remaining

Eagle came second with 1/3 of the remaining votes

1/3 of the remaining votes

= 1/3 × 201

= 201/3

= 67 votes

67 students voted for the eagle

Step-by-step explanation:

Given

[tex]\frac{3}4}[/tex] ÷ [tex]\frac{1}{16}[/tex]

Leave the first fraction, change division to multiplication and turn the second fraction upside down, that is

[tex]\frac{3}{4}[/tex] × [tex]\frac{16}{1}[/tex] ← cancel 4 and 16 by 4

= [tex]\frac{3}{1}[/tex] × [tex]\frac{4}{1}[/tex] = [tex]\frac{4(3)}{1(1)}[/tex] = [tex]\frac{12}{1}[/tex] = 12

Answer:

x = 1

Step-by-step explanation:

Subtract 10 from 8 to get -2. Then divide -2x by itself so it will cancel out. Whatever you do to one side of the equation, do to the other so divide -2 by -2 to get your answer of 1

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

[tex]-2x+10=8[/tex]

So let's solve this equation.

So first, we're gonna have to minus 10 from both sides of the equation.

[tex]-2x+10-10=8-10[/tex]

Now let's turn this into a fraction and divide by -2

[tex]\frac{-2x}{-2} =\frac{-2}{-2}[/tex]

[tex]x=1[/tex]

So now we have our answer!

123.45 = 12345 × 10−^2

Answer:

12345([tex]10^{-2}[/tex])

Step-by-step explanation:

To do this you would just multiply 123.45 by 100 so you have no decimals and you would get 12345 and then since is goes up by 100 you would get [tex]10^{-2}[/tex] because you would take 2 decimal places from that so you would get

12345([tex]10^{-2}[/tex]) as your answer

Divide each term in the bracket by 4:

=  

3

x

−

2

Explanation:

Multiplying by  

1

4

is the same as dividing by 4. - You are finding a quarter of something.

To find a quarter of the bracket, divide each coefficient by 4.

You will get two unlike terms so you will not be able to simplify them.

This is the reason why you cannot simplify inside the original bracket either.

Answer:

Step-by-step explanation:

1) Find the first derivative of f(x). 2) Plug x value of the indicated point into f '(x) to find the slope at x. 3) Plug x value into f(x) to find the y coordinate of the tangent point. 4) Combine the slope from step 2 and point from step 3 using the point-slope formula to find the equation for the tangent line.

Answer: Option A, the square root of 40, is an irrational number.

Step-by-step explanation:

We are given 4 options:

- the sqrt of 40

- the sqrt of 49

- the sqrt of 100

- the sqrt of 9

All but one are perfect squares. Let's find out which one is not a perfect square.

The sqrt of 49 is 7. 7 times 7 is equal to 49.

The sqrt of 100 is 10. 10 times itself is equal to 100.

The sqrt of 9 is 3. 3 times 3 is equal to 9.

What about the square root of 40?

We know it's not a perfect square, and it's somewhere between 6 and 7. So, the hint from the question tells us that imperfect squares are irrational. Then this must be the answer!

Answer:

A. √40

Step-by-step explanation:

√49 = 7

√100 = 10

√9 = 3

but,

√40 = 6.32455532, so this is immperfect square

Answer:

1/12 mi/min = 0.083 mi/min

Step-by-step explanation:

From the question given above, we obtained the following information:

Distance (d) = 5/6 mile

Time (t) = 10 mins

Speed (S) =?

Speed is simply defined as the rate of change of distance moved with time. It can be represented mathematically by the following equation:

Speed (S) = Distance (d) / time (t)

S = d/t

With the above formula, we can calculate Ellie's speed as follow:

Distance (d) = 5/6 mile

Time (t) = 10 mins

Speed (S) =?

S = d/t

S = 5/6 ÷ 10

S = 5/6 × 1/10

S = 5/60

S = 1/12 mi/min = 0.083 mi/min

Therefore, Ellie's speed is 1/12 mi/min.

Ellie speed in miles per minute is 1 / 12

Speed is a scalar quantity with only magnitude and no direction. Speed measures how fast an object is in motion.

Speed is represented mathematically as follows:

speed = distance /time

Ellie covers 5/6 miles in 10 minutes. Therefore,

distance = 5/6 miles

time = 10 minutes

Speed = [tex]\frac{\frac{5}{6} }{10}[/tex] = [tex]\frac{5}{6}[/tex] ×[tex]\frac{1}{10}[/tex] = [tex]\frac{5}{60}[/tex] = [tex]\frac{1}{12}[/tex] miles per minutes

Answer: 18.5

Step-by-step explanation:

The way to find the mean of a data set is to add up all the values and then divide by the number of data points.

First add up all of the values. 12+14+22+14+18+23+42+13+9+19+22+14=222.

Now count how many data points there are. There are 12 data points.

Finally, divide the sum you got by the number of data points. 222/12=18.5

Answer:

Step-by-step explanation:

-6 + y + 10y

= 11y - 6

Answer:

-6+11y or 11y-6

Explanation:

Since there is a - in front of the parentheses it wants you to multiple by -1, which will be equal to 10y. 10y+y=11y. After this, you would add the -6, or subtract 6 from that.

it would be 13.96 for the volume

Step-by-step explanation:

So we have the function:

[tex]h(n)=3n[/tex]

And we want to find h(6).

To do so, simply substitute 6 for n. In other words:

[tex]h(n)=3n\\h(6)=3(6)[/tex]

Multiply:

[tex]h(6)=18[/tex]

So, our answer is 18 :)

Answer:

h(6) = 18

Step-by-step explanation:

To evaluate h(6), substitute n = 6 into h(n) , that is

h(6) = 3(6) = 18
