Volume of rectangular prism = 81 feet³

Explanation:

Volume of rectangular prism is same as volume of cuboid

Length = 9 ft

Width = 4 ft

Height = 2 \frac{1}{4} ft = \frac{9}{4} ft

Volume of rectangular prism = Length × Width × Height

= 9 × 4 × \frac{9}{4}

= 36 × \frac{9}{4}

= \frac{324}{4}

How are simple carbohydrates able to form larger macromolecules
madreJ [45]

Answer:

Carbohydrates can be described as biological molecules which are made up of carbon, hydrogen and oxygen.

Simple carbohydrates are known as monosaccharides. Example of monosaccharide includes glucose and fructose. Two molecules of monosaccharides can join to form disaccharides. Example of disaccharide includes maltose. When three or more monosaccharides join they form polymers known as polysaccharides. In this way, simple carbohydrates form larger molecules or polysaccharides. Examples of polysaccharides include starch, glycogen, cellulose etc.

Why are economic impacts important to consider when planning to address climate change? Wealthy people and businesses won't supp
kherson [118]

Answer:

The projections, if they play out, illustrate the potential magnitude of decisions such as the recent one by President Trump to walk away from the international Paris climate accord, in which more than 170 countries agreed to slash their carbon emissions in coming years. Meanwhile, hundreds of governors, mayors and other elected officials have vowed to continue the shift toward cleaner sources of energy.

Hsiang acknowledged that despite the researchers’ efforts to use sound statistical approaches and a wealth of databases, calculating the future costs of climate change is inherently uncertain. Communities are likely to adapt and become more resilient. Industries evolve and relocate.

Delavane Diaz, a senior technical leader at the Electric Power Research Institute, agreed that the study has limitations. For one, it fails to account for how humans will probably plan for and respond to the changing climate. Still, she said, the conclusions provide an important glimpse of the economic risks the United States could face as global warming worsens.
