Answer:

Total volume of the figure = 1067 cm³

Step-by-step explanation:

Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid

Volume of the rectangular prism = Length × Width × Height

                                                      = 10 × 10 × 7

                                                       = 700 cm³

Volume of the square pyramid = \frac{1}{3}(\text{Area of the base})\times (\text{height})

                                                   = \frac{1}{3}(\text{Side})^2 × height

                                                   = \frac{1}{3}(10)^2(18-7)

                                                   = 366.67 cm³

Total volume of the composite figure = 700 + 366.67 = 1066.67 cm³

                                                                                          ≈ 1067 cm³

What is the value of y when x = 3. y = 12x
alexandr1967 [171]
We have the equation y = 12x. And we know the value of x. The value of x is 3.
So, if we replace the x variable with the value of x, then we can solve the equation.

y = 12(3)
y = 36

So, the answer is 36.

sergejj [24]

Answer:

slope = -3

y-intercept = -2

Step-by-step explanation:

y = mx + <em>b</em>

m = slope; <em>b</em> = y-intercept

y= -3x <em>- 2</em>

m = -3 = slope

<em>b = -2 = y-intercept</em>
