Sara has lived 18.0 years. How many seconds has she lived? Express the answer in scientific notation. Use 365.24 days per year f

Contact [7]

Answer:

She has lived $5.68021248\times 10^8\ \text{seconds}$ .

Step-by-step explanation:

Given : Sara has lived 18.0 years.

To find : How many seconds has she lived?

Solution :

Using conversions,

1 year = 365.24 days

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

Converting 18 years into seconds,

$18 \text{years} = 18\times 365.24\times 24\times 60\times 60\ \text{seconds}$

$18 \text{years} =568021248\ \text{seconds}$

In scientific notation,

$18 \text{years} =5.68021248\times 10^8\ \text{seconds}$

Therefore, she has lived $5.68021248\times 10^8\ \text{seconds}$ .

. In the design of an electromechanical product, 12 components are to be stacked into a cylindrical casing in a manner that mini

Harlamova29_29 [7]

Answer:

(a) 479,001,600 combinations (b) 95,040 combinations (c) 3,326,400 combinations

Step-by-step explanation:

(a) In the case we have 12 different elements to stack, the possible combinations can be calculated as a premutation of 12 elements:

P = 12! = 479,001,600 combinations

(b) If seven components are identical, we have a permutation with repetition.

We have 7!=5040 combinations that are the same, so there is only one unique out of 5040 combinations. We have to divide the total possible combinations by 5040.

P = 12! / 7! = 479,001,600 / 5,040 = 95,040 combinations

(c) In the same way, if we have 3 components of Type 1 and 4 components of Type 2 (and the others all different), we have 3!*4! = 144 combinations that are the same.

P = 12!/(3!*4!) = 479,001,600 / 144 = 3,326,400 combinations

A box of stuffing costs $1.99 for 16 oz. Find the unit cost, round to the nearest hundredth.

Misha Larkins [42]

The given ratio is:

$\frac{\text{ \$1.99}}{16oz}$

To find the unit cost per ounce, we can use proportions as follows:

$\frac{\text{ \$1.99}}{16oz}=\frac{x}{1oz}$

Now, solve for x:

$\begin{gathered} x=\frac{1oz\cdot\text{ \$1.99}}{16oz} \\ x=0.12 \end{gathered}$

The cost per ounce (unit cost) is then $0.12/oz
