All I know is the first one is -0.8 ft/min
Step-by-step explanation:
height= 4b
length = 2 + b
volume = 60in³
or, l ×b × h = 60in³
or, (2+b) × b × 4b = 60in³
or, 4b²(2+b) = 60in³
or, 8b² + 4b³ = 60
or, 2b² + b³ = 15
or, b³ + 2b² -15= 0
b= 1.95
l= 2+1.95=3.95
h= 4×1.95 = 7.8
Answer:
3.Mean 15.4, Median: 13, Mode: None, Range 16
Step-by-step explanation:
The 5 in the hundredths place represents 5/100, whereas the 5 in the tens place represents 50, Figure out how 5/100 and 50 are related to each other: (5/100)x = 50. Mult. both sides by 100, we get 5x = 5000. Thus, the 5 in the tens place is 1000 times the 5 in the hundreths place.
