Answer:

The answer to your question is letter D. x = 64

Step-by-step explanation:

Equation

                                       log x 8  = 0.5

Express the log as a exponential equation

                                        xx^{0.5} = 8

Express the power as a fraction

                                        x^{1/2} = 8

                                        \sqrt{x^{2}}

Look for a number which squared root is 8

                                        \sqrt{64} = 8

Then

                                        x = 64

Mai wants to make an open top box by cutting out corners of a square piece of cardboard and folding up the sides. The cardboard
Bumek [7]

Answer:

V(x)=(4x^{3}-40x^{2}+100x)\ cm^3

The domain for x is all real numbers greater than zero and less than 5 com

Step-by-step explanation:

<em><u>The question is</u></em>

What is the volume of the open top box as a function of the side length x in cm of the square cutouts?

see the attached figure to better understand the problem

Let

x -----> the side length in cm of the square cutouts

we know that

The volume of the open top box is

V=LWH

we have

L=(10-2x)\ cm

W=(10-2x)\ cm

H=x)\ cm

substitute

V(x)=(10-2x)(10-2x)x\\\\V(x)=(100-40x+4x^{2})x\\\\V(x)=(4x^{3}-40x^{2}+100x)\ cm^3

Find the domain for x

we know that

(10-2x) > 0\\10> 2x\\ 5 > x\\x < 5\ cm

so

The domain is the interval (0,5)

The domain is all real numbers greater than zero and less than 5 cm

therefore

The volume of the open top box as a function of the side length x in cm of the square cutouts is

V(x)=(4x^{3}-40x^{2}+100x)\ cm^3

slamgirl [31]
The answer is 2 in 20 or 1 in 10, all you have to do is add up the total number of marbles and then have the number of yellow in the total. So 2 in 20. Hope this helps you!

How to subtract unlike fractions
topjm [15]
Find the common denominator for both unlike fractions.

EX:   1                        2
         12                      8

The lowest common factor is both fractions is 24.           Multiply both denominators to get 24. 

Do not forget to multiply the numerators with the number you used to multiply the denominators together.        

You do not have to multiply each side by the same number.
