<h3>The first time when the ball will reach a height of 20 feet is 0.42 seconds</h3>
<em><u>Solution:</u></em>
Given that,
<em><u>The height of a ball thrown into the air after t seconds have elapsed is:</u></em>
<em><u>What is the first time, t, when the ball will reach a height of 20 feet?</u></em>
Substitute h = 20
<em><u>Solve by quadractic formula</u></em>
Rounding off we get,
t = 2.08 , t = 0.42
Thus the first time when the ball will reach a height of 20 feet is 0.42 seconds
Answer:
Answer:
Total number of cards = 32(4) or y=32(4)
Roberto had 128 cards.
Step-by-step explanation:
Consider the provided information.
Part (A)
He gave his four friends 32 baseball cards each.
Let the number of cards he have before giving them to his friends is y.
This can be written as:
y = 32(4)
Part (B)
Now solve the above equation as shown.
y = 32(4)
Multiply 32 with 4
y = 128
Hence, Roberto had 128 cards.
