Caroline and her mom are building a skateboard ramp for their driveway. The angled ramp is 20 feet long. It starts on ground level and ends at a height of 1.5 feet. What is the angle of elevation of the ramp? Round to the nearest tenth.

The Lamberti family is building a rectangular deck that measures 30 feet by 22 feet. They need to run an electric line across the diagonal, underneath the deck. How long is the diagonal of the deck, to the nearest foot?

Jake is installing a staircase so his children can have access to a tree house he built. The rise of the stairs is 7 inches and the run of each stair Is 10 Inches. What is the slope of the staircase, expressed as a fraction?

What is the ADA act (the Americans with Disabilities Act)?

The Americans with Disabilities Act requires that wheelchair ramps have at least a 12-inch run for each rise of 1 inch. a. Determine the slope represented by this requirement. b. The maximum length that the law allows for a ram is 30 feet. How many inches tall is the highest point of this ramp?

The Fickman Construction Company is building a rectangular deck that measures 40' by 20'. They need to run an electric line across the diagonal, underneath the deck. How long is the diagonal of the deck, to the nearest foot?

Safety In 1990, the Americans with Disabilities Act (ADA) went into effect. This act made provisions for public places to be accessible to all individuals, regardless of their physical challenges. One of the provisions of the ADA is that ramps should not be steeper than a rise of 1 foot for every 12 feet of horizontal distance. What is the slope of such a ramp?

Fats, such as butter, and oils, such as corn oil, are formed from compounds called fatty acids, one of which is linolenic acid (C$_{18}$H${30}$O$_2$). Linolenic acid undergoes reactions with hydrogen and oxygen to form the products shown in each equation.
[1] C$_{18}$H${30}$O$_2$ + H$_2$ $\rightarrow$ C$_{18}$H$_{36}$O$_2$
[2] C$_{18}$H${30}$O$_2$ + O$_2$ $\rightarrow$ CO$_2$ + H$_2$O\

a. Calculate the molar mass of linolenic acid.
b. Balance Equation [1], which shows the reaction with hydrogen.
c. Balance Equation [2], which shows the reaction with oxygen.
d. How many grams of product are formed from 10.0 g of linolenic acid in Equation [1]?
