Answer:
x= 28
Step-by-step explanation:
The angles both sum up to 180°. So, the equation would be: 39+(5x+1)= 180.
Step 1- Add common numbers.
(39+1)+5x= 180
40+5x= 180
Step 2- Subtract 40 to both sides.
40+5x= 180
-40 -40
5x= 140
Step 3- Divide both sides by 5.
<u>5x</u>= <u>140</u>
5 5
x= 28
Answer:
Intersect
Step-by-step explanation:
A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees
Answer:
A) A(t) = 4500*π - 1600*t
B) A(4) = 7730 in³
C) t = 8,8 sec
Step-by-step explanation:
The volume of the sphere is:
d max = 30 r max = 15 in
V(s) = (4/3)*π*r³ V(s) = (4/3)*π* (15)³
V(s) = 4500*π
A) Amount of air needed to fill the ball A(t)
A(t) = Total max. volume of the sphere - rate of flux of air * time
A(t) = 4500*π - 1600*t in³
B) After 4 minutes
A(4) = 4500*π - 6400
A(4) = 14130 - 6400
A(4) = 7730 in³
C) A(t) = 4500*π - 1600*t
when A(t) = 0 the ball got its maximum volume then:
4500*π - 1600*t = 0
t = 14130/1600
t = 8,8 sec
