Answer:
-8 1/2 ft / min
Step-by-step explanation:
X = second diver rate
1 1/2 X = -12 3/4
3/2 X = - 51/4
X = - 51/4 * 2/3 = - 102/12 = -8 1/2 ft / min

Answer:
4A=5.1 per million 4B=3.8 years
Step-by-step explanation:
4A. A=0.2^2+.01t+5.1 the current level would be 5.1
4B. 8=.2t^2+.01+5.1 minus 8 .2t^2+.01-2.9
t=(-1.0+squ.0001-41-.58)/.4
t=(-.01+squ2.3201)/.4
t=3.78 t+3.78=0 =-3.78
t=-3.83 t-3.83=0 =3.83
Answer 3.83 years
Answer:
The surface area of the rectangular prism is 52 square feet (ft²), if the height is 4 feet, width is 3 feet and depth is 2 feet.
Step-by-step explanation:
The given is,
A prism of
Let, h - height of the prism
w - Width of the prism
d - Depth of the prism
Step:1
From given,
h = 4 feet
w = 3 feet
d = 2 feet
Step:2
Formula to calculate the surface area of the rectangular prism is,
A=2(wd+hd+hw)
Substitute the values of w,d and h
= 2 [(3×2) + (4×2) + (4×3)]
= 2 (6+8+12)
= 2 × 26
= 52
A = 52 Square feet
Result:
Thus the surface area of the rectangular prism is 52 square feet (ft²), if the height is 4 feet, width is 3 feet and depth is 2 feet.
