Answer:
31.41 ft²
Step-by-step explanation:
Heron's formula is useful when you have the three side lengths.
A = √(s(s -a)(s -b)(s -c)) . . . . sides are a, b, c and s = (a+b+c)/2
Using the given side lengths, we have ...
s = (8 +8.4 +13.5)/2 = 29.9/2 = 14.95
A = √(14.95(14.95 -8)(14.95 -8.4)(14.95 -13.5)) = √(14.95×6.95×6.55×1.45)
A = √986.81399375 ≈ 31.41 . . . . square feet
Answer:
V = 4 volt
Step-by-step explanation:
Given: Electrical power (w) P = 0.5 watt and resistance R ( Ω ) R = 32 ohm
Voltage V = ? (volt)
Formula for calculating electrical power is:
P = V² / R => V² = P · R => V ) √P · R = √0.5 · 32 = √16 = 4 volt
V = 4 volt
God with you!!!
Answer:
that would be 4/13
Step-by-step explanation:
i think
The proportion would go as follows:
2 C
5 = 145 Its hard to type that but 2 would go over the 5 and an equals sign would be in the middle, then C over 45. To solve then take 145 times 2 and divide it by 5.
Hope this helps.
hope can help u !!!!!!!!!!
