Height of the pentagon = 9 ft
Edge of base = 3 ft
s is the length of any side = 3
n is the number of sides = 5
tan is the tangent function calculated in degrees
Volume of the pentagon = area of base (height )
Volume of the pentagon = 15.4852 (9)
Volume of the pentagon = 139.366
Volume of the pentagon = 139.37 cu.ft
Answer:
1/12
Steps:
1 - 2/3 = 1/3
1/3 / 4 = 1/3 × 1/4 = 1/12
Answer:
$1920
Step-by-step explanation:
Original amount: £1200 x Simple interest rate: 0.2 x number of years: 3 = 720
Add Original onto simple interest
£1200 + £720 = £1920
Total Cost of personal loan after 3 years = £1920
Answer:
x = 10
Step-by-step explanation:
To find x, write a proportion between the side lengths for the similar triangles in the figure.
To solve, cross multiply and isolate x.
(x+5)(12) = 18(x)
12x + 60 = 18x
60 = 6x
10 = x
Answer:
Hillary 2400
carlton 800
will 3200
ashley 1600
Step-by-step explanation:
hillary 30% of 8000 ---- 8000:100×30=2400
will 2/5 of 8000 8000:5×2=3200
carlton 1/4 of will's---- 3200:4=800
ashley: rest, which is 8000-(2400+3200+800)=8000-6400=1600
