Mr. Schordine wants to fill up enough helium balloons to allow him to fly through the skies. He weighs 84 kilograms. He knows that every cubic meter of helium is able to lift about 1 kilogram, and the package for the balloons that he bought says that every balloon can be inflated to a sphere with a radius of 0.4 meters. How many balloons would it take to fulfill Mr. Schordine’s dream of flight?

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.

Enter the amplitude of the function. f(x)=3cosx

(08.06 mc) devon and his friends bought strawberry wafers for $3 per packet and chocolate wafers for $1 per packet at a carnival. they spent a total of $30 to buy a total of 22 packets of wafers of the two varieties. part a: write a system of equations that can be solved to find the number of packets of strawberry wafers and the number of packets of chocolate wafers that devon and his friends bought at the carnival. define the variables used in the equations. part b: how many packets of chocolate wafers and strawberry wafers did they buy? explain how you got the answer and why you selected a particular method to get the answer
