1,2,5 please I don’t really understand this lesson :(:/
AKA 1,2,5 only!

Answer:

Step-by-step explanation:

Volume of a triangular pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]

1). Volume of the pyramid = [tex]\frac{1}{3}(72)(15)[/tex]

                                           = 360 cm³

2). Volume of the pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]

   Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]

                                                 = [tex]\frac{1}{2}(8)(5)[/tex]

                                                 = 20 cm²

   Therefore, volume of the pyramid = [tex]\frac{1}{3}(20)(12)[/tex]

                                                             = 80 cm³

5). Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]

    Here, r = radius of the circular base

    h = Height of the cone

    Volume of the cone = [tex]\frac{1}{3}\pi (2)^2(4)[/tex]

                                      = [tex]\frac{16\pi }{3}[/tex]

                                      = 16.76 cm³

When three squares are joined at their vertices to form a right triangle, the combined area of the two smaller squares is the same as the area of the largest square. Which three squares will support this statement?

what is the nearest percent of 20 students to 30 students​

Select ALL the correct answers.
Carmen and Matt are conducting different chemistry experiments in school. In both experiments, each student starts with an initial amount of water in a flask. They combine two chemicals which react to produce more water. Carmen's experiment starts with 30 milliliters of water in a flask, and the water increases in volume by 8.5 milliliters per second. Matt's experiment starts with 10 milliliters of water and increases in volume by 28% each second.




Which two conclusions can be made if f represents the volume of water in Carmen's flask and g represents the volume of water in Matt's flask?

The volume of water in Carmen's flask is increasing at a faster rate than the volume of water in Matt's flask over the interval [6, 8].
The volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval [4, 6].
The volume of water in Carmen's flask will always be greater than the volume of water in Matt's flask.
The volume of water in Matt's flask will eventually be greater than the volume of water in Carmen's flask.
The volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval [0, 2].
