Answer:
393.6
Step-by-step explanation:
1 minute=60 seconds
60 seconds x 2 meters= 120 meters
3.28 feet x 120 meters=393.6
Answer:
x = 12
Step-by-step explanation:
The mistake made here is in making 130 = 9x + 7. They are not the same.
The central angle = 130 degrees.
Any angle sharing the endpoints of the central angle and having it's vertex on the same side of the central angle is 1/2 the central angle.
1/2 the central angle = 130 /2 = 65
Cyclic quadrilaterals (those with all 4 points touching a circle's circumference) have opposite angles supplementary.
65 + 9x + 7 = 180 Combine like terms on the left
72 + 9x = 180 Subtract 72 from both sides
72 - 72 + 9x = 180-72 Combine
9x = 108 Divide by 9
9x/9 = 108/9
x = 12
18) Value of b is : 
Option A is correct.
19) Option C is correct.
Step-by-step explanation:
18) We need to find the value of b.
The given equation is:
Solving to find the value of b:
So value of b is :
Option A is correct.
19) We need to find the correct graph of the equation:
Solving:
The values of y will be less than three. As y < 3 so, the circle on y is not filled.
So. Option C is correct.
