Answer:
Step-by-step explanation:
Volume of a pyramid = (l×b×h)/3
V = 128cm^3,
l = 8cm
b = 8cm (/because is a square base)
Substituting this values
128 = (8×8×h)/3
Cross multiply
128×3 = 64h
384 = 64h
Dividing through by 64
h = 384/64
h = 6cm
Height is 6cm
The answer for simplifying the fraction would be 7/12 and in decimal form 7/12 to decimal would be 0.583333
Answer:
all real numbers
Step-by-step explanation:
The function f(x) = 3|x +4| +1 is defined for all values of x. Its domain is <em>all real numbers</em>.
Answer:
5
Step-by-step explanation:
-6+2n=3n-(6+5)
-6+2n=3n-11
-6+2n-3n=-11
-6-n=-11
n=-6-(-11)
n=-6+11
n=5
The solution would be like this for this specific problem:
Volume of a cylinder = pi * r^2 * h
Volume of a cone = 1/3 * pi * r^2 * h
Total Height = 47
Height of the cone = 12
Height of the cylinder = 35
If the top half is filled with sand, then:
volume (sand) = pi * 4^2 * 36
volume (cone) = 1/3 * pi * 4^2 * 12
Total volume = 1960.353816 cubic millimeters
353816 / (10 * pi) = 62.4 seconds.
It will take 62.4 seconds until all of the sand has dripped to the bottom of the hourglass.
