Answer:
Step-by-step explanation:
convert 1 day into hours
1 day=24 hour
2/24
=1/12
Answer:
$27.12
Step-by-step:
So, we first need to learn how much money the tax is. We can find it like this
8.5 8.5x12.50
------ x 12.50 = ----------------
100 100
106.25
= ------------- = 1.0625 ~~ $1.06
100
The tax is $1.06
So now, the only thing left is to add
12.50 + 1.06 = $13.56
13.56x2 = $27.12 (for both gifts)
In total, both gifts cost $27.12 with tax.
In total, both gifts cost
<u>We are given:</u>
The function: y = -16t² + 64
where y is the height from ground, t seconds after falling
<u>Part A:</u>
when the droplet would hit the ground, it's height from the ground will be 0
replacing that in the given function:
0 = -16t² + 64
16t² = 64 [adding 16t² on both sides]
t² = 4 [dividing both sides by 16]
t = 2 seconds [taking square root of both sides]
<u>Part B:</u>
for second droplet,
height from ground = 16 feet
time taken = t seconds
acceleration due to gravity = 10 m/s²
initial velocity = 0 m/s
h = ut + (1/2)at² [second equation of motion]
16 = (0)(t) + (1/2)(10)(t²)
16 = 5t²
t² = 16/5
t = 1.8 seconds (approx)
Therefore, the second droplet takes the least amount time to hit the ground
Forty million, twenty-three thousand and thirty-two
