Mrs. Clark wants to plant rose bushes along the front of her house. The length she wants to cover is 13 feet, and she wants to a

larisa86 [58]

Answer:

Mrs Clark spends in total $119 on rose bushes.

Step-by-step explanation:

Here, the total length that needs to be covered = 13 ft

The distance between 2 consecutive rose pant = 2 ft

Cost of planting each bush = $17

Now, if we plant first plant at 1 feet,

Then the second bush will be planted at a distance of 2 ft + 1 ft = 3 ft

Third bush = Second Bush + 2 ft = 3 ft + 2 ft = At 5 ft

Fourth bush = Third Bush + 2 ft = 5 ft + 2 ft = At 7 ft

Fifth bush = Fourth Bush + 2 ft = 7 ft + 2 ft = At 9 ft

Sixth bush = Fifth Bush + 2 ft = 9 ft + 2 ft = At 11 ft

And, lastly Seventh bush = Sixth Bush + 2 ft = 11 ft + 2 ft = At 13 ft

So, as to cover a total of 13 ft, 7 bushes are planted in total which are 2 ft apart from one another.

Now, cost of planing 7 rose bushes = 7 x ( Cost of planting 1 rose bush)

= 7 x ($17) = $119

Hence, Mrs Clark spends in total $119 on rose bushes.

Represent the number 108 in expanded form and exponent

lubasha [3.4K]

<h3>Further explanation</h3>

Let's recall following formula about Exponents and Surds:

$\boxed { \sqrt { x } = x ^ { \frac{1}{2} } }$

$\boxed { (a ^ b) ^ c = a ^ { b . c } }$

$\boxed {a ^ b \div a ^ c = a ^ { b - c } }$

$\boxed {\log a + \log b = \log (a \times b) }$

$\boxed {\log a - \log b = \log (a \div b) }$

<em>Let us tackle the problem!</em>

$\texttt{ }$

$108 = 54 \times 2$

$108 = (27 \times 2) \times 2$

$108 = (9 \times 3) \times 2 \times 2$

$108 = (3 \times 3) \times 3 \times 2 \times 2$

$108 = 3^3 \times 2^2$

$\texttt{ }$

<h3>Conclusion:</h3>

The number 108 could be represented in expanded form and exponent as following:

$\boxed{ 108 = 3^3 \times 2^2 }$

$\texttt{ }$
