She could switch them around by grouping them into groups of 4s, 3s, 2s, or 5s.
The return trip was 21.2 hours long.
Step-by-step explanation:
Given,
Speed of plane from US = 212 mph
Speed of plane on return trip = 232 mph
Let,
x be the time taken on return trip.
Time taken from US = x+2
We know that;
Distance = Speed * Time
Distance of plane from US = 212(x+2) = 212x+424
Distance on return trip = 232x
As the distance will be same, therefore,
![232x=212x+424\\232x-212x=424\\20x=424](https://tex.z-dn.net/?f=232x%3D212x%2B424%5C%5C232x-212x%3D424%5C%5C20x%3D424)
Dividing both sides by 20
![\frac{20x}{20}=\frac{424}{20}\\x=12.2\ hours](https://tex.z-dn.net/?f=%5Cfrac%7B20x%7D%7B20%7D%3D%5Cfrac%7B424%7D%7B20%7D%5C%5Cx%3D12.2%5C%20hours)
The return trip was 21.2 hours long.

Answer:
$384.75
Step-by-step explanation:
Albert's hourly pay is $8.10
When he works for more than 40 hours, his hourly pay will increase to $12.15.
Last week, Albert worked for 45 hours, his hourly pay would be:
First 40 hours = $8.10 * 40 = $324
Remaining 5 hours =
$12.15 * 5 = $60.75
Albert gross pay for this period will be calculated as:
$324 + $60.75 = $384.75
Therefore, Albert gross pay for this period = $384.75
Answer:
48.06 to the nearest hundredth.
Step-by-step explanation:
f(x) = -16x^2 + 2x + 48
To find the maximum height we convert to vertex form:
= -16(x^2 + 1/8x) + 48
= -16[x + 1/16)^2 - 1/256] + 48
= -16(x + 1.16)^2 + 16/256 + 48
= 48.0625.
