Given that
3x :8= 7:2
Calculate the value of x

Answer: C; 3 4/2

Step-by-step explanation:  A fraction exponent can be represented using a radical. The base number is the number in the radical. The numerator of the fraction is the exponent inside the radical. The denominator is the type of radical.

An exponential always crosses at (0,1) This function crosses at (0.6) meaning it has shifted up 5 units or +5. These means only answer options A and D are possible solutions. Also, since the graph starts high and ends low and leveling out, this means the base is less than 1. Only 3/4 is less than 1. Answer A is the solution.

hope this helps, thank you! :)

Calculation to Find two positive numbers

First step

Let the first positive number be a

Let the second positive number be b

Second step is to create the Equation

a^2+b= 54....... Equation (1)

b = 54-a^2........ Equation (2)

Third step is to find the product

Product= a(54-a)^2 = 54a-a^3

Fourth step is to differentiate

dP/dx = 54-3a^2

dP/dx = 0

Fifth step is to solve for 54-3a^2 = 0

Hence,

3a^2=54

a^2 = 18

Last step

a= √(18)

b= 54-(√(18))^2

b=54-18

b = 36

Therefore the two positive numbers are 36

Answer:

Please check the explanation.

Step-by-step explanation:

We know that when y varies directly with x, we get the equation

y ∝ x

y = kx

k = y/x

where 'k' is called the 'constant of direct variation'.

We are given that x = -2 and y = -2

Thus,

The equation is:

y = kx

substituting x = -2 and y = -2

-2 = k(-2)

-2 = -2k

We can further simplify the equation to determine the value of 'k'

so

dividing the equation by -2

-2/-2 = -2k/-2

1 = k

Therefore, the value of k = 1

Thus, the equation becomes

y = kx

substituting k = 1 in the equation

y = (1)x

y = x

Therefore, an equation that relates x and y is:

y = x

Answer:

i think 8/1000

Step-by-step explanation:

The fraction is 8/9.

Any number that can be expressed as a fraction and where the denominator (the bottom number) and the numerator (the top number) are both integers is considered a rational number.

We have the decimal is 0.8(bar).

let x= 0.888888....    (1)

Now, multiply above equation by 10

10x = 8.8888.....         (2)

Subtraction equation (1) and (2), we get

10x - x = 8.8888.... - 0.88888...

9x = 8

x = 8/9

Thus, the fraction is 8/9.

Answer:

The volume is [tex]10.648 \times10^{-18}[/tex] cm³

The scientific notation [tex]1.0648 \times10^{-17}[/tex] cm³.

Step-by-step explanation:

Consider the provided information.

The side of a cube measures [tex]2.2\times10^{-6}[/tex] cm.

The volume of cube = [tex]s^3[/tex]

Where, s is the side.

The volume of cube: [tex]V=(2.2\times10^{-6})^3[/tex] .

[tex]V=(2.2)^3 \times(10^{-6})^3[/tex]

[tex]V=10.648 \times10^{-18}[/tex]

Hence, the volume is [tex]10.648 \times10^{-18}[/tex] cm³

Answer:

a= 12, b= 24, c = 12, d= 12root3

Step-by-step explanation:

Because the triangle to the left is a right triangle with a 45 degree angle, we can deduce that it is a 45-45-90 special triangle where a =c. Furthermore, a and c = the hypotenuse divided by root 2.

12 root 2 / root 2 = 12

a=12, c=12

The triangle to the right is a right triangle with a 30 degree angle, so it is a 30-60-90 special right triangle.

If a = 12, b is 2 times a

b= 2*12 = 24

If a =12, d = a * root 3

d= 12root3

Answer:

Your answer will be x=2

Step-by-step explanation:

Five plus 6 times a number is equal to 21 minus 2 times the number

Your equation is this:

5+6x=21-2x

Subtract 6x from both sides

5+6x-6x=21-2x-6x

5=21-8x

subtract 21 on both sides

5-21=21-21-8x

-16=-8x    Divide -8 on both sides

2=x

Answer:

to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.
