The total surface area of the United States is 9.6 × 106 km2. Seventy-four percent of this land can support spiders. Given that there are approximately 5.0 × 104 spiders per acre, how many spiders are there in the United States? Recall that 1 acre = 0.004 km2.
As the human population grows and as the average rate of resource use per person rises, water shortages in many parts of the world are becoming
more severe and, thus, more of a global concern. It is predicted that humans will have no cholce but to reduce their water footprints in the near
future.
A water footprint is an estimate of how much water it takes each year to meet the needs of a person, a population, or a country. Currently, the total
water footprint of U.S. citizens is 2,487 cubic meters per year per capita (m/yr/ca). This is equivalent to 657,000 gallons/yr/ca, or more than 16,000
bathtubfuls of water per year!
From what you know about water footprints, which of the following makes up the majority of the average American's water footprint?
O Water used in washing machines
O Water used in the production and delivery of food and consumer goods
O water consumed from using household toilets and showers

- W meters L meters A town has a large unused field, A rectangular portion of the field will be enclosed by a fence for a dog park, The park will be W meters wide and L meters long, where the length is two times the width. The park will be enclosed by a fence on all 4 sides, with an additional segment of fence running through the middle of the park, dividing it into two square areas. If a total of 1,400 meters of fence is used to enclose the park and divide it into the two square areas as described, which of the following systems of equations could be solved to determine the width and length of the park? W = 2L A 1 2W + 2L = 1,400 W = 2L 3W + 2L = 1,400 Barrow_forwardBonuan Beach, also known as Tondaligan Beach, is one of the most popular beaches in Pangasinan. Many Pangasinense enjoy the view of sunrise and sunset in this place. They also love swimming especially nowadays that COVID restrictions are being lifted in so many areas. Bonuan Beach was also rehabilitated and restored. For these reasons, a group of SHS STEM students, wants to help maintain the cleanliness of the beach. So, they proposed a project study entitled "Automatic Garbage Collection, through Electric Force, Field and Gauss's Law". They proposed a panel full of negative charges so that garbage will be attracted towards the panel.
