I hate it here and also math sorry hint try a gaine a aging number too
Answer:
166
Step-by-step explanation:
A=2(wl+hl+hw)=2·(4·5+7·5+7·4)=166
50 x 5280 = 264,000 feet in 50 miles
60 x 60 = 3600 seconds per hour
264000/3600 = 73.33 rounded to 73 feet per second
Answer:
± 60
Step-by-step explanation:
aₙ = a₁ * rⁿ⁻¹
a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶ (1)
a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴ (2)
(1)/(2): 30/120 = 1/4 = r²
r = ± 1/2 or ± 0.5
a₁ = a₇/r⁶ = 30/0.5⁶ = 1920
a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60
