Answer:
31/42
Step-by-step explanation:
there are 42 students in 8th grade
31 dont play keyboard so 31/42 = 73.8% chance
184 x 7 = 1288
7 x 6 = 42
so you have 42 <span>defective bulbs</span>
It can travel 125km with 5 liters
And 6 liters to travel 150 :)
An equation is formed of two equal expressions. The equation of the exponential graph is A=100(0.5)ˣ.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation of an exponential function is given by the formula,
y = A (B)ˣ
Now as per the graph, there are two points (1, 50) and (2, 25).
50 = A (B)¹
50 = AB
A = 50/B
Substitute another point in the equation,.
25 = A (B)²
25 = (50/B) (B)²
25 = 50B
B = 0.5
Substitute the value of B,
A = 50/0.5 = 100
Hence, the equation of the exponential graph is A=100(0.5)ˣ.
