Answer:
P = 64 cm
Step-by-step explanation:
<C = 150° - 90° = 60°
AB = AC
∠B = ∠C = 60° } => ΔABC = EQUILATERAL TRIANGLE =>
=> BC = 10 cm
P = 10cm + 8cm + 6cm + 10cm + 6cm + 6cm + 8cm + 10cm
P = 3x10cm + 2x8cm + 3x6cm
P = 30cm + 16cm + 18cm
P = 64 cm
Answer: i think its c.....but....... yea i think it is
The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the cesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s-1.
<span>x+5y=8 ----------------- (1)
</span>y=3x ----------------- (2)
Substitute (2) into (1):
x + 5(3x) = 8
Distribute 5:
x + 15x = 8
Combine like terms:
16x = 8
Divide both sides by 16:
x = 0.5
Substitute x = 0.5 into (2):
y = 3(0.5)
Distribute 3
y = 1.5
Answer: x = 0.5, y = 1.5
