Answer:
£7
Step-by-step explanation:
x - .2x = £5.60
.8(x) = £5.6
x= £5.6/.8
72⁰_______3π m
360⁰______15π m
C = 15π = 2π r
r = 7•5 m
Step
<u>Find the value of x</u>
we know that
m∠FLI=m∠FLG+m∠GLH+m∠HLI ---------> equation
In this problem we have
m∠FLI=°
m∠FLG=°
m∠GLH=°
m∠HLI=°
Substitute the values in the equation
Combine like terms
°
Step
<u>Find the value of each angle</u>
Substitute the value of x in each angle
m∠FLG=°
m∠GLH=°
m∠HLI=°
therefore
<u>the answer is</u>
The smallest angle in the diagram is
%change=100(final-initial)/initial
%change=100(63-90)/90
%change= -30%
So the price was decreased by 30%
Assuming by "20111" you mean 2011.
The difference in years is 2011 and 1990 is 21 years.
In 21 years the rate of change was "-$1850" (44,450 - 6,300).
Furthermore, this can be divided by 21 to get the AVERAGE rate of change in 1 year
21 years / -1850 = -$88.096 (3 DP)
