Answer:
15.41
Step-by-step explanation:
Answer:
1. rate = 30, base = 40, percentage = 12
2. rate = 6, base = 24, percentage = 25
3. rate = 16, base = 64, percentage = 25
4. rate = 4, base = 50, percentage = 20
5. rate = 75, base = 80, percentage = 60
Step-by-step explanation:
Answer:
1.
Mathematical concept that expresses an amount in relation to the computer unit; results from counting the elements that make up a set.
"Cardinal number"
2.
A graphic sign or set of graphic signs that expresses or represents that amount.
Step-by-step explanation:
So the trapezoid has 2 parallel sides making segments AD and BC transversals
Therefore making angle c and angle b add up to 180
(180-3x) + 3x + 180-9x +9x
180 +12x = 360
180= 12x
x= 15
Step-by-step explanation:
radius of sphere, rs
radius of cylinder, rc
height of cylinder, h
given: h = rs = rc =r..eq1
volume of cylinder, vc = 27pi ft...eq2
volume of cylinder, vc = pi × rc^2 × h...eq3
volume of sphere, vs = 4/3(pi×rs^3)...eq4
subst for h & rs from eqn 1 in eqn 3...
vc = pi x r^2 x r= pi x r^3...eqn 5
subst for vc from eqn 2 in eqn 5...
=> 27 pi ft = pi x r^3
=> 27 = r^3
=> r = 3ft...eqn 6
subst for rs from eqn 1 in eqn 4
vs = 4/3 (pi x r^3)...eqn7
subst for pi x r^3 from eqn 5 in eqn 7
vs = 4/3 vc = 4/3 (27pi ft) = 36 pi ft
