Answer:
It means 2/1
Step-by-step explanation:
For example if YIU say the ratio girls to boys is 2 to 1 then you are there are 2 girls to 1 boy
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: he will have $12720 after 15 years
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $8000
r = 3.1% = 3.1/100 = 0.031
n = 12 because it was compounded 12 times in a year.
t = 15 years
Therefore,
A = 8000(1 + 0.031/12)^12 × 15
A = 8000(1 + 0.00258)^180
A = 8000(1.00258)^180
A = $12720
To compare the displayed Wright flyer in the museum with the actual plane, we have to compute for the ratio of the corresponding parameter. In this item, for both the display and the actual plane, we are given with the length. Computing for the ratio gives us,
ratio = length of the model / length of the actual plane
Length of the model = 35 cm
We need to calculate for the length of the model in ft.
length of the model = (35 cm)(1 in/2.54 cm)(1 ft/12 in)
length of the model = 1.148 ft
Going back to the equation for the ratio,
ratio = (1.148 ft)/21 ft
ratio = 0.055
Hence, the dimensions used in the model is equal to 0.055 times the actual dimensions.
Error may occur because of the number of significant figures considered for rounding up or down of the answers after each calculation.
