Answer: 64=s3

Step-by-step explanation: V=s3

64=s3

find the cubic root of each side

3√ 64=s4=s

so the side of the cube is 4 cu in.

The surface area of a cube is

SA=nA

where SA

is surface area, n

is the number of faces, and A

is the area of one face.

Te area of one face (A) is s2 so

Answer:

[tex]-\frac{4}{3}[/tex]

Step-by-step explanation:

[tex]-3 \frac{3}{5}[/tex] ÷ [tex]2 \frac{7}{10}[/tex]

Convert both mixed numbers to an improper fraction. This can be done by multiplying the denominator by the "number" part of the mixed number, then adding the result to the numerator.

[tex]- \frac{18}{5}[/tex] ÷ [tex]\frac{27}{10}[/tex]

Now divide the fractions, to divide the fractions, one will find the reciprocal of the recond fractions, and then multiply it by the first fractions. Remember, the reciprocal of a fraction is when one switched the numerator and denominator of a fraction.

[tex]-\frac{18}{5} * \frac{10}{27}[/tex]

[tex]= -\frac{180}{135}[/tex]

Simplify;

= [tex]-\frac{4}{3}[/tex]

Answer:

[tex]30[/tex]

Step-by-step explanation:

1. Approach

First, use the Pythagorean theorem to solve for the hypotenuse of the given right triangle. Then find the perimeter by adding up the values of all the sides. The problem then has the lengths of the legs doubled. When the legs undergo a scaling factor, the hypotenuse and perimeter undergo the same scaling factor. Here, the legs are doubled, hence the hypotenuse and the perimeter are also doubled. Finally, subtract the new perimeter from the original perimeter.

2. Find the original hypotenuse

Remember the Pythagorean theorem states;

[tex]x^{2}+y^{2}=z^{2}[/tex]

Where (a) and (y) are the legs (or the sides adjacent to the right angle), and (z) is the hypotenuse or the side opposite to the right angle.

Substitute in the given value and solve,

[tex](5)^{2}+(12)^{2}=z^{2}\\\\25 + 144 = z^{2}\\\\169=z^{2}\\\\\sqrt{169}=z\\\\13=z[/tex]

3.Find the perimeter of the original triangle

To find the perimeter of a polygon, one must add up the lengths of all the sides.

[tex]5 + 12 + 13\\\\= 30[/tex]

4. Find the new perimeter

In a right triangle, when both legs undergo a scaling factor, the hypotenuse also has the same change, and the perimeter also undergoes the same change. In this case, the length of the legs is doubled, therefore, the hypotenuse and the perimeter are also doubled.

New hypotenuse; [tex]26[/tex]

New perimeter; [tex]60[/tex]

5. Find the difference

Now all that is left is to subtract the new perimeter from the original perimeter;

(New_perimeter) - (original_perimeter)

= [tex]60 - 30[/tex]

= [tex]30[/tex]

Answer:

A

Step-by-step explanation:

Because it would be how many adults times 36. And how many ever children times 15. And that total would be equal to $234

Answer:

The total number of vehicles is: x = 120

Hence, option C is correct.

Step-by-step explanation:

Total trucks that were sold in one month = 72 trucks

Let 'x' be the total number of vehicles.

Given that 60% of  the total vehicles sold were trucks.

Thus,

60% of x =  72

60/100 × x = 72

x = [72 × 100] / [60]

x = 120

Therefore, the total number of vehicles is: x = 120

Hence, option C is correct.

Answer:

C 120

Answer:

same amount at 2 months. he'd pay 140.

Step-by-step explanation:

35(month) +35(month) =70(joining fee). 70+70=140. that's two months at the first gym.

the second gym is also 140 for the two months because each month is $70. and 70+70=140

Answer:

Did you know that Aronson and Carnes-McNaughton's have the perspective on how they   study

ancient  things from the past.I agree that Aronson will agree with Carnes--McNaughton's statement because they both  said the same thing but just in different words. For example  in the book "If Stones Could Speak," it will tell what  Aronson statement was about when it comes to archaeology  and in "Profiles Of Archaeologist," it will tell you the same statement but just in different words. For example it states in the book "If Stones Could Speak," on page 56 "Marc Aronson believes that, “It is about putting aside what you think you know, what has been passed along, and being willing to trust what you yourself see and to test it rigorously.” From this quote the reader will now know what Aronson thinks when it comes to archaeology. In "Profiles Of Archaeologist." On paragraph 19 It states "Being an archaeologist means looking at the world around us in a different perspective. We live in the present as we study the past in  order to learn what  to do in the future---- on this planet and possibly other. We learn to be humanities  while at the same time we practice as scientists.  From this quote the reader can understand that both of these statements are similar but they are just reworded. In closing, This why I think that Aronson and Carnes will agree to what to what there statement was.

Step-by-step explanation:

Answer:

Part 1: At eight hours they both charge the same.

Part 2: Flush Plumbing charges the least

Step-by-step explanation:

Part 1:

Flush Plumbing Co Equation: 50 + 10 h (h = hours)

Fire-in-the-hole Plumbing: 90 + 5h (h = hours)

50 + 10h = 90 + 5h

Solve the Equation:

5h = 40

h = 8

Part 2:

Plug in 7:

Flush Plumbing: 50 + 10 x 7 = 50 + 70 = $120

Fire-in-the-hole Plumbing: 90 +5 x 7 = 90 +35 = $125

Flush plumbing chargers the least

10/4=2.5

Answer:

I think 2.5 years

Answer:

2t^2 - 37t + 171

Step-by-step explanation:

distrube the - to the (t-9) and then combine like terms

Answer:(2t2 +  27t) -  162  = 0  

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  2t2+27t-162  

The first term is,  2t2  its coefficient is  2 .

The middle term is,  +27t  its coefficient is  27 .

The last term, "the constant", is  -162  

Step-1 : Multiply the coefficient of the first term by the constant   2 • -162 = -324  

Step-2 : Find two factors of  -324  whose sum equals the coefficient of the middle term, which is   27 .

     -324    +    1    =    -323  

     -162    +    2    =    -160  

     -108    +    3    =    -105  

     -81    +    4    =    -77  

     -54    +    6    =    -48  

     -36    +    9    =    -27  

     -27    +    12    =    -15  

     -18    +    18    =    0  

     -12    +    27    =    15  

     -9    +    36    =    27    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -9  and  36  

                    2t2 - 9t + 36t - 162

Step-4 : Add up the first 2 terms, pulling out like factors :

                   t • (2t-9)

             Add up the last 2 terms, pulling out common factors :

                   18 • (2t-9)

Step-5 : Add up the four terms of step 4 :

                   (t+18)  •  (2t-9)

            Which is the desired factorization

Equation at the end of step

2

:

 (2t - 9) • (t + 18)  = 0  

STEP

3

:

Theory - Roots of a product

3.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.
