Answer:
4164.69504π
Step-by-step explanation:
So the volume of a cone is πr^2 * h / 3
r = 15.072 / π
h = 55
15.072 / π squared * π = 227.165184π
227.165184π * 55 / 3 = 4164.69504π
For this case we have the following equation:
S = 0.159 + 0.118logD
Substituting S = 0.2 we have:
0.2 = 0.159 + 0.118logD
From here, we clear the value of D.
We have then:
0.2 - 0.159 = 0.118logD
logD = (0.2 - 0.159) / (0.118)
logD = 0.347457627
10 ^ (logD) = 10 ^ 0.347457627
D = 10 ^ (0.347457627)
D = 2.23 mm
Answer:
The average diameter, D, of the sand particles for a beach is:
D = 2.23 mm
Answer:
Length = 22 feet Width= 8.5 feet
Step-by-step explanation:
Perimeter= 61
Let Width= x
Length= 2x+5
Perimeter= 2l + 2w
61= 2(2x+5) + 2x
61 = 2(2x+5+x)
61/2 = 3x+5
30.5 -5 = 3x
25.5 = 3x
25.5/3 =x
x= 8.5
Hence, width = 8.5 feet
Then, the length = 2x+5 = 2(8.5) +5 = 22 feet
Hope this helps!
Answer:
2) 19 dollars and 63 cents.
Step-by-step explanation:
not inc. tax = $15.70.
18% tip x $15.70=$2.83
7% tax x $15.70 = $1.10
$15.70 + $2.83 + $1.10 = $19.63
