Answer:
Volume of prism = 39 km cubed
Step-by-step explanation:
<u>IMPORTANT FORMULA: Volume of any prism = Area of base * Height </u>
<u />
In this case, <u><em>the area of the base</em></u> means <u><em>the area of the trapezoid. </em></u>
Area of trapezoid = base1+base2/2 * height
Area of trapezoid = 8+5/2 * 1.5
Area of trapezoid = 13/2 * 1.5 = 9.75
We already know that the height of the trapezoidal prism is 4 kilometers.
So, we have all of the values that are needed to correctly fill in the formula.
Volume of the prism = 9.75 * 4 = 39
Answer: 530
Step-by-step explanation:
First u add 50, 30+50=80, the. 80+100=180, 180+150=330, 330+200= 530 and so on
Answer:
0.18
Step-by-step explanation:
126/7 = 18 so the quotient is 18. There is no need to use distributive property.
(7 - 2i)(8 + 9i)
= 7(8 + 9i) + -2i(8 + 9i)
= 56 + 63i + -16i - 18i²
= 56 + 47i +18 <em> (NOTE: i² = -1 → (-18)(-1) = +18)</em>
= 74 + 47i
Answer: 74 + 47i
