The weights of nine members of an excise class were:
135, 162, 128, 117, 146, 173, 128, 150, 161
Find the range of these weights

If everyone loses 4 pounds in two weeks, what effect will this have on the range?

Range=26

Range after everyone loses 4 pounds=22

Step-by-step explanation:

You subtract 161-135, carry 1 from 6 and change 6 to 5, 11-5=6, 5-3=2, and voila.

The range is 56 originally.

Step-by-step explanation:

Then if everyone loses 4 pounds it does not change because they all changed together. If one person lost the 4 pounds then it would have an affect because it changes the amount in weight. Instead off all together weight. Lol idk if I make since but that's the answer.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
