His average was 55.0 seconds, multiply that by the number of times he ran. This will give you the total time:

55.0 * 3 = 165 total seconds.


Subtract his times for the fastest and slowest to find the time for the third one:

165 - 54.3 - 56.1 = 54.6


The third race was 54.6 seconds.

a quarterback is sacked for a loss of 5 yards.On the next day his team loses 15 yards.Then the team gains 12 yards on the third
Veronika [31]

Assume it is first down and ten in this problem. When you lose 5 yards on the sack, you are 5 yards further away. So now, it is second and 15. Then, they lose another 15 yards, so it's now third and 30. The final play is that they gain 12 yards, meaning after all the plays it is fourth down and eighteen yards to go.

In math symbols, 0 is where the first down marker is. You start at -10.

First play, the sack: -10 - 5 = -15

Second play: -15 - 15 = -30

Third play: -30 + 12 = -18.

Looks like you have to punt on fourth down :)

According to postal regulations, the girth plus the length of a parcel sent by fourth-class mail may not exceed 108 in. What is
solmaris [256]

Answer:

  11,664 in³

Step-by-step explanation:

For a square side length of x, the girth is 4x and the length of the parcel is then allowed to be up to 108-4x.

The total volume is the product of the edge lengths, so is ...

  V = (108 -4x)(x²) = -4x³ +108x²

This will be a maximum where its derivative is zero:

  dV/dx = -12x² +216x = 0 = -12x(x -18)

This is zero for x=0 and for x=18.

The maximum volume parcel is 18 in by 18 in by 36 in, and has a volume of ...

  (18 in)(18 in)(36 in) = 11,664 in³

How do you find out the percentage of 55% of 140
qwelly [4]
I just found 10% of it, which is 14, then found 5% of it through the previous work, which is 7

then i multiplied 7 by 11, because 55/5 is 11, so 55% of 140 is 77
