Answer:

Option b is correct.

Step-by-step explanation:

\sqrt[3]{b^{27} }) =(b^{27}) ^{\frac{1}{3} } =b^(\frac{27}{3} )= b^9\\

Explanation in words

We can write any radical form in to exponent form therefore we wrote

cube root in to exponent form as \frac{1}{3}

In second step we used the formula for exponent of exponent  of terms

which gives  27 divided by 3 in the exponent of b consequently we get

9 in the exponent of b or we can write b^9 which gives option b as the answer.

Answer: b. b^9


Step-by-step explanation:

1. You can rewrite  \sqrt[3]{b^{27}} as following:

(b^{27})^{\frac{1}{3}}

Because, by definition \sqrt[n]{x}=x^{\frac{1}{n}}

2. Now, keeping on mind the exponents properties, you can multiply the exponents, then you obtain:

b^{\frac{27}{3}}

3. Finally, you must simplify the exponent, then, you obtain the following result:

 b^{9}

Musya8 [376]

Answer:

There are 200 trees per acre.

Step-by-step explanation:

47000 trees divided by 235 acres gets you 200 trees per acre.

When you go back and check your work, 200 trees per acre times 235 acres equals 47000 trees.

I hope this helps! :)

In an arithmetic sequence, if you are given a3=93 and a5=135, find a=100. Must show work to receive full credit.
Elanso [62]

The 100th term of the sequence is 2130.

<h3>How to calculate the value?</h3>

a3 = a + 2d = 93

a5 = a + 4d = 135

Compute both equations

(4d - 2d) = (135 - 93)

2d = 42

d = 42/2 = 21

a + 2d = 93

a + 2(21) = 93

a + 42 = 93

a = 94 - 42 = 51

100th term will be:

= a + 99d

= 51 + 99(21)

= 51 + 2079

= 2130

If a cube has a volume of 9 feet and a shelf has a height of 27 inches, can the cube fit in the shelf?
rusak2 [61]

Answer:

Yes the cube will fit.

Step-by-step explanation:

If we don't take into account of how wide of long the cube is and just focus on the height, the edge of a cube with a volume of 9 feet is roughly 2.08 feet. That totals to less than 27 inches, therefore the cube will fit on the shelf.
