Answer: 0.7, 0.2, 0.1

Step-by-step explanation:

For this question, you have to convert each of the fractions into decimals.

You can directly convert 7/10 into a decimal, this is 0.7

You cannot directly convert 1/5 into a decimal, so you have to convert it into tenths first.

To do this, multiply the numerator and denominator by 2

1 x 2 = 2

5 x 2 = 10

2/10

Now you can convert 2/10 directly into a decimal, this is 0.2

And finally you can convert 1/10 into a decimal, this is 0.1

hope this helps :)

Answer:

Its either answer B. or D. Sorry if I'm wrong and I hope this sorta helps.

Step-by-step explanation:

Let x be the smallest even integer.

Then (x + 2) and (x + 4) are the other even integers.

We have x + (x + 2) + (x + 4) = 138.

=> 3x + 6 = 138

=> 3x = 132

=> x = 44.

Hence the smallest integer is 44.

Answer:

4

Step-by-step explanation:

The area is 16, and you know that it's 2 sides u need to multiply

The perimeter is 16, and you know that you need to add up all the sides

So....

A = b * h

A = 4 * 4

A = 16    CORRECT

And....

P = S + S + S + S                                                         ( s = sides)

P = 4 + 4 + 4 + 4

P = 16 CORRECT

Hope this helped!

Answer:

8 1/4

Step-by-step explanation:

4 1/2 + 3 3/4   make the denominators the same

4 2/4 + 3 3/4   add the whole numbers

7 + 2/4 +3/4   add the fractions

8 1/4

Answer: 3

Step-by-step explanation:

I took 4 1/2 and made it an improper fraction which is 9/2 and then I took 3 3/4 and turned it into an improper fraction which is 15/4, so now you need to find the common denomerator which is 8 then you add the numerators which is 9 and 15 is 24 so can be divided by 8 so 24 divided by 8  is 3 and 8 divided by 8 is 1 so now you have another improper fraction 3/1 which is just 3. So that is how I got the answer!! :)

Answer:

[tex]\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7[/tex]

Step-by-step explanation:

Given

[tex]\frac{3x^6}{6x^{-1}}[/tex]

Required

Solve

In laws of indices, we have:

[tex]\frac{x^m}{x^n} = x^{m-n}[/tex]

So, the expression becomes:

[tex]\frac{3x^{6 - (-1)}}{6}[/tex]

[tex]\frac{3x^{6 +1}}{6}[/tex]

[tex]\frac{3x^7}{6}[/tex]

Divide 3 and 6 by 3

[tex]\frac{1x^7}{2}[/tex]

[tex]\frac{x^7}{2}[/tex]

This can be rewritten as:

[tex]\frac{1}{2}x^7[/tex]

Hence:

[tex]\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7[/tex]

Answer:

Step-by-step explanation:

Put it in Desmos, and it’ll show you

The reasonable domain of the function is 8 ≤ x ≤ 24.7.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = -0.5x² + 16x – 96

The function represents the height of a rocket as a function of its horizontal position.

It is reasonable to assume that the rocket is launched from the ground

(x = 0) and that it has some minimum height (above ground level) before it is launched.

Now,

We can find this minimum height by finding the vertex of the parabola, which is given by.

x = -b / (2a)

where a = -0.5 and b = 16.

Plugging in these values, we get.

x = -16 / (2(-0.5))

x = 16

Now,

The vertex occurs at x = 16.

To find the minimum height, we can plug this value into the function.

f(16) = -0.5(16)² + 16(16) - 96

       = 128

Therefore,

The rocket has a minimum height of 128 feet above ground level before it is launched.

To find the reasonable domain of the function.

Since the rocket is launched from the ground at x = 0 and has a minimum height of 128 feet, it is reasonable to assume that the rocket will remain above ground level for all values of x greater than or equal to 8, since the rocket must clear a height of 128 feet by the time it reaches x = 8.

Now,

We can find the x-value where the rocket reaches ground level

(i.e., its height is zero) by setting f(x) = 0.

Solving for x.

-0.5x² + 16x - 96 = 0

Using the quadratic formula.

x = ( -16 ± √(16² - 4(-0.5)(-96)) ) / (2(-0.5))

x = ( -16 ± √(1216) ) / (-1)

x ≈ 24.7 or x ≈ 7.3

Since the rocket is launched from the ground at x = 0, it is not reasonable to consider values of x less than 0.

Therefore,

The reasonable domain of the function is 8 ≤ x ≤ 24.7

This means,

The rocket will remain above ground level for all values of x between 8 and approximately 24.7.

Thus,

The reasonable domain of the function is 8 ≤ x ≤ 24.7.

Answer:

The capacity of bucket is 16 liters

Step-by-step explanation:

Let j be the quantity of water in the jug

Then

[tex]j = 800ml[/tex]

Let B be the quantity of water held by the bucket

Then t is given that the bucket holds 20 times of water than the jug

[tex]B = 20j[/tex]

Putting the value of j

[tex]B = 800(20) = 16000[/tex]

We also know that

1 liter = 1000 ml

In order to convert ml into liters, we have to divide the quantity by 1000

[tex]B = \frac{16000}{1000} = 16\ liters[/tex]

Hence,

The capacity of bucket is 16 liters
