Answer:
2.58 seconds
Step-by-step explanation:
When you complete the square, you get ...
h = -16(t -9/16)^2 +60 +81/16
Then the solution for h=0 is ...
t = (x -9/16)^2 = 1041/256
t = (9 +√1041)/16 ≈ 2.57903 ≈ 2.58
It takes about 2.58 seconds for the ball to hit the ground.
Answer:
Total cost of buying both items is $36.21.
Step-by-step explanation:
We are given that a baseball cost $7 and a baseball bat cost $27.
Also, we are given a tax rate of 6.5%
Now, to find the total cost of both items we will find the individual costs of both items by applying tax rate on it.
<u><em>Cost of baseball after applying tax rate is given by;</em></u>
Since we know that by applying a tax on any item it's cost gets increased.
So, Cost of baseball after tax = Cost of baseball before tax + Amount of tax
Amount of tax = Tax rate Cost of baseball
= 6.5% $7
= = $0.455
So, Cost of baseball after tax = $7 + $0.455 = $7.455
<u><em /></u>
<u><em>Cost of baseball bat after applying tax rate is given by;</em></u>
Cost of baseball bat after tax = Cost of baseball bat before tax + Amount of tax
Amount of tax = Tax rate Cost of baseball bat
= 6.5% $27
= = $1.755
So, Cost of baseball bat after tax = $27 + $1.755 = $28.755
Now, <u>the total cost of buying both items</u> = Cost of baseball after tax + Cost of baseball bat after tax
= $7.455 + $28.755 = $36.21
Therefore, the total cost of buying both items is $36.21.
