Answer:
(7) 1482 in³
(8) 216 yd³
Step-by-step explanation:
Formulas
<u>Volume</u><u> </u><u>of</u><u> </u><u>prism</u>
= base × height/length
<u>Area of parallelogram</u>
= base × height
<u>Area of trapezium</u>
= (upper base + lower base) × height ÷ 2
(7)
Area of the base = 19×6
= 114 in²
Length = 13 in
Volume = 144×13
= <u>1482 </u><u>in</u><u>³</u>
(8)
Area of the base = (11+7)×12÷2
= 108 yd²
Length = 2 yd
Volume = 108×2
= <u>216 yd³</u>
Answer: 2%, ROUNDED
Step-by-step explanation:
You must divide 100 (whole percent) by 52 (Cards in a Deck) and you will get 1.92307692308%. But if we round it, we get 2%.
So the answer is 2%.
Answer:
True
Step-by-step explanation:
True, because a polygon have all angles that are equal and all lengths are the same length.
17)
x² + 8 = -8
x² = -8 - 8
x² = 16
x = ±√-16
x = ±√16i
x = <span>±4i
</span>
18)
x² + 5 = -3
x² = -3 - 5
x² = -8
x = ±√-8
x = ±√8i
x = ±2√2i
19)
x² + 3 = 0
x² = -3
x = ±√-3
x = <span>±</span>√3i
hope this helps, God bless!
