Answer:
The better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.
Step-by-step explanation:
To find which is the better deal, you have to determine which one offers a lower unit price by dividing the price of each package by the number of balls in the pack:
$4.47/12=$0.37
$14.46/18=$0.80
According to this, the answer is that the better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.
Answer:
dA/dt = 0.375√3 ft² ≈ 0.6495 ft²/s
Step-by-step explanation:
The area is given by the formula ...
A = (1/2)ab·sin(C)
where a and b are side lengths, and C is the angle between them. Differentiating, we have ...
dA/dt = (1/2)ab·cos(C)·dC/dt
Filling in the given information, we get ...
dA/dt = (1/2)(3 ft)(5 ft)(cos(π/6))(0.1 rad/s) = 0.75(√3)/2 ft²/s
dA/dt = 0.375√3 ft² ≈ 0.6495 ft²/s

Answer: 
Step-by-step explanation:
Given equation: 
, d(t), in meters, the rock travels after t seconds .
At t=5
The rock travels distance=
At t=10
The rock travels distance=
Total distance traveled by rock 5 and 10 seconds after it was dropped
=80-20=60 m
Total time =10-5=5 seconds
We know that the average speed =
