That would be 400 / 28 = 14.29 gallons to nearest hundredth
Answer:
The angle it turns through if it sweeps an area of 48 cm² is 448.8°
Step-by-step explanation:
If the length of a minute hand of a clock is 3.5cm, to find the angle it turns through if it sweeps an area of 48 cm, we will follow the steps below;
area of a sector = Ф/360 × πr²
where Ф is the angle, r is the radius π is a constant
from the question given, the length of the minute hand is 3.5 cm, this implies that radius r = 3.5
Ф =? area of the sector= 48 cm² π = 
we can now go ahead to substitute the values into the formula and solve Ф
area of a sector = Ф/360 × πr²
48 = Ф/360 ×
× (3.5)²
48 = Ф/360 ×
×12.25
48 = 269.5Ф / 2520
multiply both-side of the equation by 2520
48×2520 = 269.5Ф
120960 = 269.5Ф
divide both-side of the equation by 269.5
448.8≈Ф
Ф = 448.8°
The angle it turns through if it sweeps an area of 48 cm² is 448.8°
Answer:ANSWER would either be 120π or about 376.8
Step-by-step explanation:
A=2πrh+2πr2
A=2π*6*8+2π*6*2
A=96π+24π
A= 120π
or
A≈376.8
ANSWER would either be 120π or about 376.8
Answer:
B) Brand 2
Step-by-step explanation:
Brand 1: $10.68 ÷ 12 = 0.89
Brand 2: $9.44 ÷ 16 = 0.59
Brand 3: $15.30 ÷ 18 = 0.85
Brand 4: $21.84 ÷ 24 = 0.91
Brand 5: $20.40 ÷ 30 = 0.68
Least cost per packet is of Brand 2
Answer:

In order to satisfy this distribution we need that each observation on this case comes from a normal distribution, because since the sample size is not large enough we can't apply the central limit theorem.
Step-by-step explanation:
For this case we have that the sample size is n =6
The sample man is defined as :

And we want a normal distribution for the sample mean

In order to satisfy this distribution we need that each observation on this case comes from a normal distribution, because since the sample size is not large enough we can't apply the central limit theorem.
So for this case we need to satisfy the following condition:

Because if we find the parameters we got:


And the deviation would be:

And we satisfy the condition:
