The nearest tenth would be the first decimal place, so the answer would be 23.8
Answer:
Below.
Step-by-step explanation:
a. Φ^2 − Φ − 1 = 0
Φ2 − Φ = 1
(Φ - 0.5)^2 - 0.25 = 1
(Φ - 0.5)^2 = 1.25
Φ - 0.5 = √(1.25) (We only take the positive root).
Φ = 0.5 + √(1.25)
b. I used Completing the square.
c. Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.
C is the correct answer. An equilateral triangle is a type of triangle.
Answer:
Step-by-step explanation:
Tax payable:
= $4,543+($41,000-$39,476)×22%
= $4,543+$335.28
= $4,878.28
Tax rate:
= $4,878.28/$41,000
= 11.9%
<em>Hence, Tax rate is 11.9%</em>
Volume of cylinder = πr^2 × h
= π × (5/2)^2 × 13
= 255.25 yd^3
