Answer: Alex Swims 63 mi in one minute 24 seconds
Explanation:
Alex swims 45 miles in 1 minute so what we need to find is the 24 seconds.
You'd take 2 divided by 5 which is the simplified fraction of 24 seconds over 60 seconds
Simplifying the fraction to a decimal gives you 0.4 then multiply it by 45 giving 18.
45+18=63 mi
D. high and low levels of silica in the different type of lava.
Explanation:
The volcanoes have different types of explosions. Some tend to be highly explosive, some less explosive, some don't have explosions at all, while some have combinations of different eruptions. The reason for this diversity in the eruption types is mostly the composition of the magma, or rather how high is the silica content in it.
Basically, the higher the silica level in the magma the higher the explosiveness, and the lower the silica level the lower the chances of explosiveness. This is the case because the higher amount of silica makes the magma thicker, so the gasses are trapped and they explode, while when the lower silica content makes the magma less thick, so the gasses are not trapped and explosions are lacking.

Answer:
The cause was the command type of economy and the result was famine and millions of deaths.
Explanation:
The communist governments in East Asia, like all communist countries, had command economies. This meant that everything in the economy is planned and regulated by the government. This was also the case with agriculture, where government officials were making a plan on how much and what should be produced. The plans were often made in the manner that it should be produced as much as society needs.
Because agriculture is heavily dependent on weather conditions, as well as the impact of pests, even the slightest disturbance meant that there won't be enough food, and if it was a bigger disturbance then a big portion of the population would have experienced a famine. This has happened on numerous occasions, with the small amount of food being forcefully transported to the cities, while the rural population that produced it was left without anything for eating. The end result has been tens of millions of deaths because of starvation, based on terrible politics.
