$5.80
Step-by-step explanation:
The 12 members spent $48 in total and the 8 nonmembers spent 68 in total. If you add those two together and divide by 20 you get 5.8.
Hey there! I’m happy to help!
We want to look for the twentieth term in this sequence. Because it is arithmetic, this means that the same term will always be added or subtracted.
As we can see, our first term is 36 and then the third is twenty eight. This is a difference of eight, and since our subtracted term will always be the same, we will take this eight and divide it by two, so we can now see that we are subtracting four for each term.
To find the twentieth term, you could count, but that would be a hassle. You can also use the arithmetic sequence formula, which I will show below.
You take the desired term (20)
Subtract 1 (19)
Multiply it by the common term/difference (19*-4=-76)
And then add the first number of the sequence (-76+36= -40)
You can now do those exact same steps for any arithmetic sequence you are dealing with!
So, your twentieth term is -40!
I hope that this helps!

Answer:
a person travel 50 ft from the bottom to the top of the escalator
Step-by-step explanation:
An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle
The escalator forms a right angle triangle
opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse
let x be the hypotenuse
a person travel 50 ft from the bottom to the top of the escalator
