So.. let's say ∡AGB and ∡BGC are say "a" units wide, and ∡CGD and ∡DGE are "b" units wide

notice the picture below

all angles added up together, will make up just a flat line, or 180°

now, notice in the picture, the ∡BGD is really just " a + b " wide, notice the green angle in the picture of ∡BGD, well, we know what a + b is

What is 19/25 as decimal
Radda [10]
Well first we need to find how we can turn 25 into 100 
Well one way would be to multiply by 4 
25 x 4 = 100 

Since we multiplied the bottom number by 4 we should multiply the top number by 4. 

So..
19 x 4 = 76

So our new fraction is..
 76 
-----
100

Now we can easily turn this into a decimal. 
76/100 = 0.76 

Answer = 0.76 

Good Luck! :)

The equation $y=-4.9t^2+3.5t+5$ describes the height (in meters) of a ball thrown upward at $3.5$ meters per second from $5$ met
Georgia [21]

Answer:

Step-by-step explanation:

The position function is

s(t)=-4.9t^2+3.5t+5 and if we are looking for the time t it takes for the ball to hit the ground, we are looking for the height of the ball when it is on the ground. Of course the height of anything on the ground is 0, so if we set s(t) = 0 and solve for t, we will find our answer.

0=-4.9t^2+3.5t+5 and factor that however you are currently factoring in class to get that

t = -.71428 seconds or

t = 1.42857 seconds (neither one of those is rational so they can't be expressed as fractions).

We all know that time will never be a negative value, so the time it takes this ball to hit the ground is

1.42857 seconds (round how you need to).
