Answer:
A. - 4
Step-by-step explanation:
f(4) = 4(4) - 20 = 16 - 20 = - 4
Answer:
35 cm
Step-by-step explanation:
volume of cylinder = πr²h
πr²h = 1058.75π
Divide both sides by π.
r²h = 1058.75 cm³
r = 5.5 cm
Substitute r² with (5.5 cm)².
(5.5 cm)²h = 1058.75 cm³
h = 1058.75/30.25 cm
h = 35 cm
Answer:
110
Step-by-step explanation:
A + b = 21 1/6 --> b = 21 1/6 - a
a - b = 4 3/6
a - (21 1/6 -a) = 4 3/6
a - 21 1/6 + a = 4 3/6
2a = 21 1/6 + 4 3/6
2a = 25 4/6
2a = 154/6
a = (154/6) / 2
a = (154/6) * (1/2)
a = 154/12
a = 12 10/12
a = 12 5/6
b = 21 1/6 -a
b = 21 1/6 - 12 5/6
b = 20 7/6 - 12 5/6
b = 8 2/6
Answer:
a = 12 5/6
b = 8 2/6
Double check:
a + b = 12 5/6 + 8 2/6
a + b = 20 7/6 ......(7/6 = 6/6 + 1/6)
a + b = 21 1/6
a - b = 12 5/6 - 8 2/6
a - b = 4 3/6
