In a science activity, the 2nd-grade students want to investigate the amount of water and sand that different types of containers can hold. They have a cylindrical and a rectangular container, both empty, and need to decide which one to use to measure the amount of water that fits in a bucket and the amount of sand that fits in a box. The cylindrical container has a capacity of 3 liters and the rectangular one weighs 2 kilograms. Considering that the density of water is 1 kilogram per liter and that of sand is 1.5 kilograms per liter, which of the containers should the students use to accurately measure the capacity of the bucket and the box, knowing that the water and sand will not be compacted?a.
For measuring the capacity of the bucket and the box, it is recommended that the students use a graduated cylinder instead of the provided containers.
b.
Due to the shape of the rectangular container, it is more suitable for measuring the capacity of the bucket and the box than the cylindrical container.
c.
The capacity of the bucket can be accurately measured by the cylindrical container, but for the box, it is better to use the rectangular container.
d.
The students should use the cylindrical container to accurately measure the capacity of the bucket and the box.
e.
The students should use the rectangular container to accurately measure the capacity of the bucket and the box.

The Science class is learning about vegetable gardens and decided to plant a small rectangular garden at school, where they will grow lettuce and carrots. The garden's rectangle measures 3 meters in length and 2 meters in width. To find out how many plants will fit in the garden, they need to calculate the perimeter. Help the students calculate the perimeter of this rectangular garden.

In a large engineering system, a building is being designed and energy efficiency is a major concern. To ensure the efficiency of heating and cooling, the air conditioning system must be sized according to the specific needs of the building. The engineer in charge of the project must solve a system of linear equations to determine the ideal operating temperatures. Let the following be the system of equations that models the thermal behavior of the building: 2x + y + 3z = 10, 4x - 6y + 8z = 5, 3x + 7y + 5z = 18. The engineer must rewrite this system of equations in the matrix form Ax = b, where A is the matrix of coefficients, x is the vector of unknowns, and b is the vector of constant terms.
