Answer:
The actual price is 13.6 % lower than the expected price....
Step-by-step explanation:
Lets suppose the expected price = x
CPI = ( expected price ) : ( price in 1983 ) *100
219 = ( x : 12.95 ) *100
Divide both sides by 100.
x : 12.95 = 2.19
x =2.19*12.95
= $28.36 ( expected price )
p = ( 24.50*100 ) / 28.36
p= 2450/28.36
= 86.4 %
100 % - 86.4 % = 13.6 %
The actual price is 13.6 % lower than the expected price....
Answer:
<a=138°
<b=42°
<c=138°
<d=138°
<e=42°
<f=42°
Step-by-step explanation:
<a is supplementary with the 42° angle:
<a=180°-42°=138°
<b and the 42° are vertical angles, so:
<b=42°
<c and <a are also vertical angles so:
<c=<a=138°
<d and <a are corresponding angles, so:
<d=<a=138°
<e and <b are corresponding angles, so:
<e=<b=42°
<f and the 42° angle are corresponding angles, so:
<f=42°
<g and <c are corresponding angles, so:
<g=<c=138°
X = year
y = total height
Type A:
y = 12x + 5
Type B:
y = 13x + 4
12x + 5 = 13x + 4
x = 1; 1 year
Answer: C) x = 7, y = -1
Step-by-Step Explanation:
=> y = -2x + 13 (Eq. 1)
=> 4x + 8y = 20 (Eq. 2)
Substitute value of ‘y’ from Eq. 1 in 2 :-
4x + 8y = 20
4x + 8(-2x + 13) = 20
4x + -16x + 104 = 20
-12x + 104 = 20
-12x = 20 - 104
-12x = -84
12x = 84
x = 84/12
=> x = 7
Substitute value of ‘x’ in Eq. 1 :-
y = -2x + 13
y = -2(7) + 13
y = -14 + 13
=> y = -1
Therefore, x = 7, y = -1 which can be written in an ordered pair as (7,-1).
