Answer:
Checkout the screenshot below the explanation.
Step-by-step explanation:
1. First, we have to simplify the inequality.
Step 1: Subtract 12 from both sides.
Step 2: Divide both sides by 8.
2. Now that we simplified our inequality down to y < -4, that means that all the values of y are less than -4.
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 =
= × height
=
= 366.67 cm³
Total volume of the composite figure = 700 + 366.67 = 1066.67 cm³
≈ 1067 cm³
