A server sees 84 customers over 6 hours. How many customers did they see in 1 hour?
AveGali [126]

Answer: 14 customers

Step-by-step explanation: Right now, you can set up an equation that looks something like this. 6h=84 (h means hours). To find the number of customers in one hour, all you have to do is isolate h on one side of the equation. To do this, just divide both sides by 6 and you should get h=14. So in one hour, this particular server sees 14 people. Hope this helps! :)

C. How can you use the area of the square to find the side length?
Kruka [31]

Answer:

Step-by-step explanation:

Since squares are the same length on each side, whatever one side is, if you square it, it will give you the area of the square. To find the length of one side, you need to do the inverse: find the square root of the area.

for example: if you have a square that is 3x3, the are is 3², or 9. Now, in order to find the length of one side, you need to do √9, which gives you 3.

Find the first four terms of each sequence. <br><br> F(n) = 3n - 1
timofeeve [1]

Answer:

2, 5, 8, 11

Step-by-step explanation:

F(n) = 3n - 1

put n=1

F(1) = 3(1) - 1 = 2

put n=2

F(2) = 3(2) - 1 = 6 - 1 = 5

put n=3

F(3) = 3(3) - 1 = 9 - 1 = 8

put n=4

F(4) = 3(4) - 1 = 12 - 1 = 11
