jenyasd209 [6]

Answer:

30 miles

Step-by-step explanation:

Let d represent the distance to the island. The relation between time, speed, and distance is ...

time = distance/speed

so the total time for the round trip is ...

d/15 +d/10 = 5

Multiplying by 30, we get

2d +3d = 150

d = 150/5 = 30

The island was 30 miles from the harbor.

The required value is $2\times10^9$

Step-by-step explanation:

Weight of ants = $4\times10^{-3}$

Weight of elephant= $8\times10^6$

We need to find, the total weight of about how many ants equals to the weight of an oversized elephant.

The equation given is:

$4\times10^{-3} \times a = 8\times10^6$

We need to find a:

Solving:

$4\times10^{-3} \times a = 8\times10^6\\a=\frac{8\times10^6}{4\times10^{-3}}\\if \,\,10^a/10^-b \,\,then\,\, 10^{a+b}\\a=2\times10^{6+3} \\a=2\times10^9$

So, the required value is $2\times10^9$
