Green Fencing Company will install the fence

LUCKY_DIMON [66]

The company would charge $837.50 to build the fence.

Installing a fence would cost $62.50 per hour.

It will take 13²/₅ hours to install this fence.

The cost would be:

= Cost per hour x Number of hours taken

Number of hours it would take should be converted to improper fraction to be multiplied:

13²/₅ = 67/5 hours

Cost is:

= 62.50 x 67/5

= $837.50

In conclusion, it would cost $837.50 to build the fence.

Kieva made 5 times as many cookies as she did cupcakes. If she made 48 deserts in all , how many cupcakes did she make ?

VikaD [51]

Kieva made 8 cupcakes. 8 * 5 + 8 = 48 desserts.

In order to get this, you just have to try out different numbers of cupcakes and adjust based on whether it's too many desserts total, or not enough.

Another way to figure it out is to say that 1 cupcake + 5 cookies = 6 desserts. Then just divide 48 by 6 to get 8 which will then show you that Kieva made 8 cupcakes.

A 1,200g block of phosphorus-32, which has a half life of 14.3 days, is stored for 100.1 days. At the end of this period, how mu

Valentin [98]

Answer:

The amount of phosphorus-32 left after 100.1 days is 9.3 g.

Step-by-step explanation:

Given:

Initial amount of Phosphorus-32 is, $N_0=1200\ g$

Time period of decay is, $t=100.1\ days$

Half life of the block is, $t_{1/2}=14.3\ days$

Now, final amount left is, $N=?$

We know that, the decay equation for a radioactive material is given as:

$N=N_0e^{-kt}\\k\to decay\ constant$

The value of the decay constant is given as:

$k=\frac{\ln 2}{t_{1/2}}\\\\k=\frac{0.693}{14.3}=0.0485$

Now, plug in all the given values and calculate 'N'. This gives,

$N=(1200)e^{(-0.0485\times 100.1)}\\\\N=9.349\approx 9.3\ g$

Therefore, the amount of phosphorus-32 left after 100.1 days is 9.3 g
