By solving a quadratic equation we will see that the egg will hit the ground after 1.58 seconds.
<h3>
How long will take the egg to reach the ground?</h3>
Here we know that the initial height of the egg is 40ft, so the equation for the height will be:
The egg will hit the ground when h(t) = 0, so we need to solve the quadratic equation:
This means that the egg will hit the ground after 1.58 seconds.

It's False because 10 people cannot be born on the same day. It's Impossible
Let x be the number of nickels and y be the number of quarters.
Then, x + y = 42 --- (1)
It is given that total value = 4.90.
Therefore, 0.05x + 0.25y = 4.9 --- (2)
Multiply (1) by 0.25
0.25x + 0.25y = 10.5 --- (3)
Now, subtract (2) from (3), we get,
0.2x = 5.6
Divide both sides by 0.2.
x = 28
x + y = 42
y = 42 - x
= 42 - 28
= 14
Hence, Mary has 28 nickels and 14 quarters in total.
I need the the measurements of the shapes to solve for "x" dude
The answer is B: 4.5 cm, 7.5 cm
Here's why: 7.5 is 3 cm more than 4.5, and when added together, 7.5 + 7.5 + 4.5 + 4.5 = 24.
