To determine the prices of a quart of strawberries and a quart of raspberries, use the two specified conditions to formulate equations. Since two unknown variables exist, two equations are necessary for the solution. Let x represent the cost of a quart of strawberries, while y represents the cost of a quart of raspberries. The first equation is 3x + 2y = 22, and the second is 5x + 4y = 39. By substituting one equation into the other after expressing one variable in terms of the other, we arrive at the values x = $3.5 and y = $5.75.
60% of 500 is calculated as 0.6 multiplied by 500, resulting in 300. Therefore, Zack would receive $300.
The result is 0.81 because you must multiply 0.60 by 1.35 to get 0.81. Then divide 0.81 by 0.60.
The domain is defined as the complete set of values of variable x for which the function is valid. In this case, the x-axis illustrates time in seconds. Therefore, we must determine all possible time values over which distance can be covered or the function is defined. It’s noted that the sprinter completed the race in 11 seconds, and the start time is 0 seconds. Hence, the value of t ranges from 0 to 11. Therefore, the domain encompasses all real numbers from 0 to 11.
To resolve this, we multiply the 30-day timeframe by 7, resulting in a total of 210 days.
