Answer:
Two angles are called supplementary when their measures add up to 180 degrees.
Answer:
d. 2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
45a−25+7a=79
45a+−25+7a=79
(45a+7a)+(−25)=79(Combine Like Terms)
52a+−25=79
52a−25=79
Step 2: Add 25 to both sides.
52a−25+25=79+25
52a=104
Step 3: Divide both sides by 52.
52a
52

a=2
(x,y)=(x1+k(x2-x1),y1+k(y2-y1))
k is determined by writing the numerator over the sum of the numerator and the denominator of the original ratio.
k=3/(3+7)=3/10.
Point A is located at (5, 10) and point B is located at (20, 25).
(x,y)=(5+(3/10)*(20-5),10+(3/10)*(25-10))
(x,y)= (9.5,14.5)
The answer would be
(9 1/2, 14 1/2)
Answer:
0.9355
Step-by-step explanation:
What we will use here is conditional probability formula.
let A be the event that the plane departs on time
and B be the event that it arrives on time
P(A) = 0.87
P(B|A) = 0.93
P(B) = ?
P(A n B) = ?
Mathematically;
P(B|A) = P(B nA)/P(A)
0.93 = 0.87/P(A)
P(A) = 0.87/0.93
P(A) = 0.935483870967742
which is 0.9355 to four decimal places
90 = 49 + x
90° - 49° = x
41 = x
I decrease it with 90 because the corner is facing. I hope the answer is right...
