Sea turtles can lay 50 to 200 eggs in a nest. Some eggs get
destroyed or eaten by other animals. The
n young turtles that hatch face many challenges
as they head to the ocean. They may have to
crawl over steep slopes, through seaweed,
or around obstacles. Raccoons, foxes, crabs,
birds, fish, and sharks may eat them. Given the
challenges and the data in the Math Toolbox,
write an expression and use it to calculate the
percent hatched. Use the percent to roughly
estimate the number of sea turtles from a nest
of 100 in Naples that reach the ocean safely.
Express your answer as a percentage.

Which type of circuit is becoming more common in residential electrical design and construction? a. hazardous-area circuit b. three-phase circuit c. 480-volt circuit d. communication circuit

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

Which of these statements is true? a. quarks pair with leptons to form protons and neutrons. b. quarks pair with bosons to form photons. c. quarks pair with photons to form protons and neutrons. d. quarks pair with other quarks to form protons and neutrons. e. quarks pair with electrons to form protons.
