Answer:
one can would be about $0.41
Step-by-step explanation:
Take $2.46 and divide it by 6 because that is the number of cans in the pack, the answer is $0.41 per can.

If each brick is within 1/8 inches of 8 inches, then that's an error of
If we then take the total length if each brick is 8 inches,
Then take 1/64 of this
![800*\frac{1}{64}=12.5[tex] So the upper and lower bounds are 12.5 inches either side of 800 inches 787.5, and 812.5 So we can say that [tex]787.5 \leq x \leq 812.5](https://tex.z-dn.net/?f=800%2A%5Cfrac%7B1%7D%7B64%7D%3D12.5%5Btex%5D%20So%20the%20upper%20and%20lower%20bounds%20are%2012.5%20inches%20either%20side%20of%20800%20inches%20787.5%2C%20and%20812.5%20So%20we%20can%20say%20that%20%5Btex%5D787.5%20%5Cleq%20x%20%5Cleq%20812.5)
Which would be the answer to part a. parts b and c would be the lower and upper bounds, so 787.5 and 812.5 respectively
Hope this helps
25 divided by 2305 is 0.0106
Answer:
Sean's rocket lands 3 seconds after Kiara's rocket.
Step-by-step explanation:
Kiara: f(t)= -16t² + 80t
Sean: h(t) = -16t² + 120t + 64
Assume that both rockets launch at the same time. We need to be suspicious of Sean's rocket launch. His equation for height has "+64" at the end, whereas Kiara's has no such term. The +64 is the starting height iof Sean's rocket. So Kiara has a 64 foot disadvantage from the start. But if it is a race to the ground, then the 64 feet may be a disadvantage. [Turn the rocket upside down, in that case. :) ]
We want the time, t, at which f(t) and h(t) are both equal to 0 (ground). So we can set both equation to 0 and calculate t:
Kiara: f(t)= -16t² + 80t
0 = -16t² + 80t
Use the quadratic equation or solve by factoring. I'll factor:
0 = -16t(t - 5)
T can either be 0 or 5
We'll choose 5. Kiara's rocket lands in 5 seconds.
Sean: h(t) = -16t² + 120t + 64
0= -16t² + 120t + 64
We can also factor this equation (or solve with the quadratic equation):
0 = -8(t-8)(2t+1)
T can be 8 or -(1/2) seconds. We'll use 8 seconds. Sean's rocket lands in 8 seconds.
Sean's rocket lands 3 seconds after Kiara's rocket.
