Answer: 270

Step-by-step explanation:

1) Find DE

1 : 6

17 : x

Cross multiply

x = 17 * 6

x = 102

DE = 102

2) Compare the two triangles

1st (ABC)

side = 45

base = 17

2nd (ADE)

side = x

base = 102

\frac{x}{45}  = \frac{102}{17}

Cross multiply

17x = 102 x 45

17x = 4590

x = 4590/17

x = 270

AD = 270

Ah clever. So you need two formulas.

1) Volume of the marble.

   4(pi)r^3/3
= 4(pi)(1.4)^3/3
<span>= 11.49 (approx)
</span>
2) Formula for density.
  
    D = M / V
        = 9 / 11.49
        = 0.78

0.78 < 1

Therefore the marble will float.

Can someone create two expressions that are equivalent to 3(4j + 4 + j). Please show all steps in your work.
NNADVOKAT [17]
12j + 12 + 3j or 15j + 12. This is because if you use Distributive Property to distribute the 3, then you multiply 3 by all the number inside the parentheses. I have two expressions because once you get get the answer after you use the property, then you can combine like terms, such as 12j and 3j which is 15j. Hope this helps!
