The ball takes 6 seconds to reach the ground.
<u><em>Explanation</em></u>
Height of the ball after seconds is represented by....
The height of the ball is 0 feet when it hits the ground. So, for finding the number of second the ball takes to reach the ground, <u>we will just plug into the above equation and then solve for .</u>
Thus...
Using zero-product property....
and
(Negative value is ignored as time can't be negative)
So, the ball takes 6 seconds to reach the ground.
Answer:
120:300 is in the same ratio as 2:5. Can you add the pound sign? My keyboard does not have it.
Step-by-step explanation:
Add the two parts of the ratio together
2 + 5 = 7
Find 5:7
5:7 = x:420
5/7 = x/420 Cross multiply
7x = 5 * 420 Combine the right
7x = 2100 Divide by 7
x = 2100/7
x = 300
Find the second number
420 - 300 = 120
120 : 300 is the answer
Divide top and bottom by 60
120/60 = 2
300 / 60 = 5
I believe your answer is 325/1.
Work:
Area = L x W
13 x 25 = 325
Substitutethe point (x1, y1) i.e. (4, 32), and m = 4 (since the lines are parallel they have the same slope) into the equation
y -y1 = m(x - x1)
e.g. y - 32 = 4 (x - 4)
