Y= 9x. If 27 dollars is the cost for 3 hours, finding the price for one hour is simple. You would take the cost divided by the time. The slope would be 9 because if you graphed (1,9) (2,18) and (3,27) [the costs per the hours] you could find that, what I use, rise over run. Basically, you can count how far from two points to get slope. Starting with the y, from 9 to 18 is 9. Then, with x, 2 to 1 is 1. So, the slope is 9/1 or 9

Find the volume of both shapes please answer will give brainiest Also please answer neatly.
SSSSS [86.1K]

Answer:

2). Volume = 14400 feet³

3). Volume = 157.5 ft³

Step-by-step explanation:

Both the figures given in the sheet attached are a rectangular pyramid and a triangular prism.

2). In this part of the question solid given is in the shape of an rectangular pyramid.

Volume of this oblique pyramid = \frac{1}{3}(\text{Base})(\text{Height})

Here 'B' = area of the base

h = height of the pyramid

Volume = \frac{1}{3}(25\times 36)\times 48

             = 14400 cubic feet

4). Volume of a triangular cone = (Area of the triangular base)×(height)

                                                    = [\frac{1}{2}(\text{Base})(\text{height})]\times {\text{height of the prism}}

                                                    = \frac{1}{2}(7\times 9)\times {5}

                                                    = 157.5 ft³
