Answer:
Step-by-step explanation:
15) t = 1 , 3t - 2 = 3*1 - 2 = 3 - 2 = 1
t =2, 3t - 2 = 3*2 - 2 = 6 -2 = 4
t = 3, 3t - 2 = 3*3 - 2 = 9 - 2 = 7
t = 4 , 3t - 2 = 3*4 - 2 = 12 - 2 = 10
Series : 1,4,7,10,.........
a = first term = 1
d = common difference = 2nd term - first term = 4 - 1 = 3
n = number of terms = 20
S = 
5620/16=351.25
Meaning you'd need 352 16-ounce bottles to hold 5620 ounces of water.

Answer:
The measure of the third angle is 92°
Step-by-step explanation:
We first have to make an equation that represents this equality. To do it we simply have to add the values that give us with x and this will result in 180 °
15° + 73° + x = 180°
once we have the equation what we have to do is solve x, so we will pass all the terms that are adding to x by subtracting 180
x = 180° - 73° - 15°
now that we have cleared the x we only have to perform the indicated operation and we will obtain the value of x
x = 92°
The measure of the third angle is 92°
