it takes 830 bricks to construct a wall that measures 14 feet 9 inches long and 6 feet high . The crew you hired can lay 300 bricks per hour . The cost of the labor is $4,000 for 8 hour work day and you can pay for a partial day. You need to build a wall 36 foot 6 in long and 6 foot high. How much will the new wall cost?​

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

boxplot e is the answer

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
