Answer:
; At-least 15 questions.
Step-by-step explanation:
Let x represent the number of questions you need to answer correctly..
We have been given that each question is worth 3 points. The points earned from answering x right questions would be .
Since we need at-least 45 points to win the game, so points earned from answering x questions would be greater than or equal to 45. We can represent this information in an equation as:
Therefore, you need to answer at-least 15 questions correctly to win the game.
The volume of the pond is 48 cubic feet. Then the weight of the water in the pond will be 2,976 pounds.
Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as
V = L x W x H
Water weighs about 62 pounds per cubic foot. The pond is 6 feet long and 4 feet wide. If the water pond is 2 feet deep. Then the volume of the water pond is calculated as,
V = L x W x H
V = 6 x 2 x 4
V = 48 cubic feet
Then the weight of the water in the pond will be given as,
W = 62 x 48
W = 2,976 pounds
The volume of the pond is 48 cubic feet. Then the weight of the water in the pond will be 2,976 pounds.
