3-2z=\frac{1}{10} \\30-20z=1\\-20z=-29 \\z=\frac{-29}{-20} \Longrightarrow z=\boxed{1.45}

For this case we have the following equation:

3-2z = \frac {1} {10}

We must find the value of z that represents the solution of the equation:

We follow the steps below:

We multiply by 10 on both sides of the equation:

10 (3-2z) = 1

We apply distributive property to the terms of parentheses;

30-20z = 1

We subtract 30 from both sides of the equation:

-20z = 1-30\\-20z = -29

We divide between -20 on both sides of the equation:

z = \frac {-29} {- 20}\\z = \frac {29} {20}\\z = 1.45

If we substitute the value of z in the original equation, equality is satisfied.

Answer:

z = 1.45

To evaluate 43/2 find A) the square of 4 and then take the cube root. B) the cube of 4 and then take the square root. C) the squ
tatiyna

Answer:

  B) the cube of 4 and then take the square root

Step-by-step explanation:

43/2 = 21.5

___

The answer choices suggest you want ...

  4^(3/2) . . . . . . . appropriate math symbols are very helpful

This can be evaluated several ways:

  4^{\frac{3}{2}}=\sqrt{4^3}=(\sqrt{4})^3=10^{\frac{3}{2}\log{4}}\\\\=8

_____

Since the 3 is in the numerator of the fraction, it represents a cube, not a cube root. Any of the answer choices suggesting cube root is involved are incorrect. (Eliminating those leaves only the correct answer choice.)

Answer:

$15

Step-by-step explanation:

Since there are 10 cards and a total possible prize of 30 dollars, the probability for each one is 30/10=3 dollars. And since 5 out of the 10 are even, you can multiply the individual amount by 5 to get a total estimated payout of $15. Hope this helps!
