Answer:
28 minutes
Step-by-step explanation:
It takes 28minutes for 7 people to paint 7 walls.

1 person = 28 minutes × 7 people =
198 people minutes = 7 walls
1 wall = 198 /7
1 wall = 28 people minutes
How many minutes does it take 14 people to paint 14 walls?

<span>Juanita
is watering her lawn using the water that is stored by rainwater.
=> the water in the tank drops 1/3 inch in every 10 minutes she waters.
=> The tanks water level is 4 feet.
Question : Number of days can Juanita waters is she waters 15 minutes per day.
=> 4 feet is the total amount of water = 1 ft = 12 inches
=> 48 inches in total
=> 1/3 inch is used every 10 minutes = 0.33 inches
=> she waters 15 minutes per day = 0.495 inches in every 15 minutes
Solution
=> 48 inches / 0.495 inches per day
=> 96.97
So Juanita can use all the water in water tank for approximately 97 days.</span>

Answer:
Step-by-step explanation:
x^2-16y-4x-12=0
Transpose and separate x and y
16y = x^2-4x-12
16y = (x^2-4x+4) -16
16y = (x-2)^2 -16
y = (1/16)(x-2)^2 -1
This means that the vertex is at
(x-2)=0 or x=2
y = -1
=> vertex (2,-1)
All you need to do is divide the number of guests (128) by how many guests can be seated at a table (8) and that will give you how many tables will be needed:
128/8=16
16 tables will be needed to seat 128 guests.
