The SA is correct but volume is off. 4/3 times pi times radius cubed is 904.7787. When making your ratio you would divide the SA by the volume to get a ratio that is about 1 to 2.

Some students washed 24 cars in 2 hours. how many cars can they wash in 15 hours?
madreJ [45]
Answer would be 180 cars.

Reason being if you take 24 and divide that by 2 you will get 12 and 12 times 15 is 180 or you could also do 24 times 7 then add 12 to get the 180 also

The area of a rectangle painiting is given by the trinomial x^2-9x-36. what are the possible dimensions of the painting ? use fa
bagirrra123 [75]
<span> (x + 3) • (x - 12)
</span>

The first term is, <span> <span>x2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> -9x </span> its coefficient is <span> -9 </span>.
The last term, "the constant", is <span> -36 </span>

Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 1</span> • -36 = -36</span> 

Step-2 : Find two factors of  -36  whose sum equals the coefficient of the middle term, which is  <span> -9 </span>.

<span><span>     -36   +   1   =   -35</span><span>     -18   +   2   =   -16</span><span>     -12   +   3   =   -9   That's it</span></span>


Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -12  and  3 
                     <span>x2 - 12x</span> + 3x - 36

Step-4 : Add up the first 2 terms, pulling out like factors :
                    x • (x-12)
              Add up the last 2 terms, pulling out common factors :
                    3 • (x-12)
Step-5 : Add up the four terms of step 4 :
                    (x+3)  •  (x-12)
             Which is the desired factorization

Final result :<span> (x + 3) • (x - 12)</span>

The dimension of the rectangle prism show are given in centimeters 4 cm 3 cm 1.4 cm what is the volume of the rectangular prism
ira [324]

Answer:

<em>16.8 cubic centimeter</em>

Step-by-step explanation:

Dimensions of rectangular prism are:

4\ cm, 3\ cm , 1.4\ cm

To find:

The volume of rectangular prism in cubic cm ?

Solution:

The formula for volume of prism is given as:

V=l\times w\times h

Where l is the length of rectangular prism

w is the width of rectangular prism

h is the height of rectangular prism

Here we are given the three dimensions of prism as:

Length, l = 4 cm

Width, w = 3 cm

Height, h = 1.4 cm

Putting the values in formula for volume:

V=4\times 3\times 1.4\\\Rightarrow \bold{V =16.8\ cm^3}

So, volume is <em>16.8 cubic centimeter</em>.
