So scale is 1:30
that mens that if the legnth of a scale wall is x then the legnth of the realll wall is 30x
legnth=3 inches
width=4 inches
actuall is
legnth=3 times 30 inches=90 inches
width=4 times 30 inches=120 inches
area=legntht imes width
90in times 120in=10800 in^2
answer is area=10800in^2
The Pythagorean theorem can tell you the length of "b".
c² = a² + b²
b² = 19² -3² = 360
b = 6√10 ≈ 18.8
Sin = Opposite/Hypotenuse
sin(A) = a/c = 3/19
A = arcsin(3/19) ≈ 9.1°
B = 90° - A = 80.9°
The remaining sides and angles are ...
b = 18.8
A = 9.1°
B = 80.9°
Answer:
2.5 dB/100 ft
Explanation:
If 5 dB was lost after 200 ft of cable and 100 ft is half of 200 ft, then the rate of loss should be 2.5 dB per 100 ft.
Step-by-step explanation:
Answer:
answer: 1/64 of 1.6%
Step-by-step explanation:
The answer is this because the probability of the spinner landing on green is 2/8 now that multiplied by itself 3 times equals 1/64 so 1/64 is the probability hope that helps!
