Answer:
1^sqrt(2) = 1 is always true
Step-by-step explanation:
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
Let's go:
The centroid of a triangle is the point of intersection of its medians. The distance from de centroid to some vertex of triangle to which it belongs is equal to 2/3 of the length of its median:
BM = 18/3 = 6

Answer:
width = 2.5 feet
Step-by-step explanation:
Suzanne has a rectangular garden which is 18 feet long and 11 feet wide.
Area of the garden = length times width = 18 times 11= 198 square foot
Let 'w' be the width of the border
Length of the garden with border = 18+2w
Width of the garden with border = 11+2w
Area of the garden with border =
Area of the border =
She has 168 square foot of paving stones,
Solve for w
apply quadratic formula
a= 4, b= 58 and c=-168
we get two values for w
Answer:
d=1.7, b=7.1
Step-by-step explanation:
3√3/3, so √3 is d, which is 1.7, b is 5 x √2, and its 7.07, so 7.1
