The numerical sum of the degree measures of ∠DEA and ∠AEB is 180°.
x = 14.5
m∠DEA = 39.5°
m∠AEB = 140.5°
Solution:
Sum of the measures of adjacent angles in a straight line is 180°.
m∠DEA + m∠AEB = 180°
The numerical sum of the degree measures of ∠DEA and ∠AEB is 180°.
⇒ m∠DEA + m∠AEB = 180°
⇒ (x + 25)° + (9x + 10)° = 180°
⇒ x° + 25° + 9x° + 10° = 180°
⇒ 10x° + 35° = 180°
Subtract 35° from both sides of the equation.
⇒ 10x° = 145°
⇒ x° = 14.5°
⇒ x = 14.5
m∠DEA = (9x + 10)°
= (9(14.5) + 10)°
m∠DEA = 39.5°
m∠AEB = (x + 25)°
= (14.5 + 25)°
m∠AEB = 140.5°
Answer:
Negative Correlation
Step-by-step explanation:
The plot looks like it's going downwards. If it was an equation, it'd be something with y = -x +b.
Answer:
t<45 mins
Step-by-step explanation:
If to qualify you must finish in less than 45 minutes, this simply means your time has to be less than 45 so it would be t<45 mins. If it had said in 45 mins or less, it would say t is less than or equal to 45 but that's not what we have here.
Answer:
$184383.7
Step-by-step explanation:
Using the formula :
V = Pe^rt
Principal, P = 85,800
Rate of interest, r = 8.5% = 0.085
Time = 9
V = 85800 * e^(0.085*9)
V = 85800 * e^0.765
V = 85800 * 2.1489943
V = 184383.71
V = $184,383.7
