Next, mult. $54000 by each of these 3 fractions:

(1/12)($54000), (3/12)($54000), AND (8/12)($54000), or

$4500, $13500, $36000

Check:  Do these amounts sum up to the original $54000?

o-na [289]

Answer:

The infant should be given 700 mg of Claforan every 8 hours.

Step-by-step explanation:

This question involves proportional measures, and asks how many mg of Claforan the infant should be given every 8 hours.

For each kg, the infant should be given 50 mg of Clarofan. The infant weighs 14 kg, so he should be given 14*50 = 700 mg of Claforan every 8 hours.

shakira invests $500000 at 5% compound intwerest per annum . calculate how many years it takes for the value to double in value?
Kay [80]

Answer:

t=14.2\ years    

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=?\ years\\ P=\$500,000\\ r=0.05\\n=1\\ A=\$1,000,000  

substitute in the formula above  and solve for t

1,000,000=500,000(1+\frac{0.05}{1})^{(1)t}

2=(1.05})^{t}  

Apply log both sides

log(2)=log[(1.05})^{t}]  

log(2)=(t)log(1.05)  

t=log(2)/log(1.05)  

t=14.2\ years
