oksano4ka [1.4K]

Answer:

44000

Step-by-step explanation:

Let w be the initial value of Otto's internet stock, in dollars. At the beginning of the year, the total value of his portfolio is w+10,000 dollars. At the end of the year, the total value of his portfolio is 1.1w+9,000 dollars. Since increasing by 6% is equivalent to multiplying by 1.06, we have

1.06(w+10,000)=1.1w +9,000

Distributing and collecting terms, we find w=40,000. At the end of the year, his internet stock is worth 40,000* 1.1=44,000 dollars.

15m is what percent of 60m; 3m; 30m; 1.5 KM? the last one is km not m

tresset_1 [31]

Answer:

1) 15 m is 25% of 60 m

2) 15 m is 500% of 3 m

3) 15 m is 50% of 30 m

4) 15 m is 1% of 1.5 km

Step-by-step explanation:

To find : 15 m is what percent of 60 m; 3 m; 30 m; 1.5 km

Solution :

1) 15 m is what percent of 60 m

Let the percent be x

So, according to question

15= x% of 60

$15= \frac{x}{100}\times 60$

$\frac{15\times 100}{60}=x$

$25=x$

Therefore, 15 m is 25% of 60 m.

2) 15 m is what percent of 3 m

Let the percent be x

So, according to question

15= x% of 3

$15= \frac{x}{100}\times 3$

$\frac{15\times 100}{3}=x$

$500=x$

Therefore, 15 m is 500% of 3 m.

3) 15 m is what percent of 30 m

Let the percent be x

So, according to question

15= x% of 30

$15= \frac{x}{100}\times 30$

$\frac{15\times 100}{30}=x$

$50=x$

Therefore, 15 m is 50% of 30 m.

4) 15 m is what percent of 1.5 km

First we change km into m

1 km=1000 m

1.5 km = 1.5×1000 m

1.5 km=1500 m

Let the percent be x

So, according to question

15= x% of 1500

$15= \frac{x}{100}\times 1500$

$\frac{15\times 100}{1500}=x$

$1=x$

Therefore, 15 m is 1% of 1.5 km.
