Answer:
5+3x=26
Step-by-step explanation:
3x is the amount of money she makes for every extra hour of service.
5 is the initial amount of money she's paid
It’s going to be 400 dollars, 20percent is 100 dollars
A) area = length x width = 12 x 6 = 72 sq.cm
B) area = 1/2x base x height = 1/2 x 3 x 6 = 9 sq.cm
C) same as B= 9 sq. Cm
D) subtract area of both triangles from area of rectangle:
72 - 9 -9 = 54 sq. Cm
Area=basexheight
Area=9x4
Area=36
Given:
Big cone : diameter = 12 cm ; height = 18 cm ; base = 14 cm
Small cone: diameter = 12 cm ; height = 6 cm ; base = 14 cm
Volume of a cone-shaped container = π r² h/3
Big cone:
V = 3.14 * (6cm)² * 18cm/3
V = 3.14 * 36cm² * 6cm
<span>V = 678.24 cm³
</span>Small cone:
V = 3.14 * (6cm)² * 6cm/3
V = 3.14 * 36cm² * 2cm
<span>V = 226.08 cm³
</span>Big cone - small cone = volume of water
678.24 cm³ - 226.08 cm³ = 452.16 cm³
