Answer:
1.30 hours
Step-by-step explanation:
Put the given number in the formula and do the arithmetic. The value of "d" is given as 7, so you are evaluating the expression ...
duration = 0.07×7^(3/2) . . . . put 7 where "d" is in the expression
= 0.07×18.520 . . . . . . . . . . . . evaluate 7^(3/2)
= 1.2964 . . . . . . . . . . . . . . . . . do the multiplication
≈ 1.30 . . . . rounded to hundredth
The duration of a storm 7 miles in diameter is predicted to be 1.30 hours.

Step-by-step explanation:
Answer:
Dimensions are 8 Inches by 14 inches by 20 inches
Step-by-step explanation:
The volume of the box is 2240. This means:
lbh = 2240
Where b is the width.
Width is two inches less than twice the height
b = 2h - 2
length is 4 inches less than 3 times the height
l = 3h - 4
Substituting these parameters into the lbh equation will yield the following:
h * (3h - 4) * (2h - 2) = 2240
h[6h^2-14h+8] = 2240
6h^3 -14h^2 + 8h - 2240= 0
Solving this cubic equation will yield one of the values to be 8. The other two values are complex numbers.
b = 2h - 2
l = 3h - 4
b = 2(8) - 2 = 14
l = 3(8) - 4 = 20
