She placed only 5 tiles the first day and started to go faster and by theend of day 4 she had placed 35 tiles.
So,
we have two points:
(1,5) and (4,35)
Slope = 30/3
= 10
Y - 5 = m(X - 1)
For 100 tiles,
100 - 35 = 10 (X - 4)
65 =10(X - 4)
6.5 = X - 4
X = 10.5
So,11th day
Answer:
14 people
Step-by-step explanation:
- A sample is defined as a set of objects or people selected by a given criteria to be studied.
-The sample's elements are unknown pre-study.

Answer:
Deandra completed the first 6 problems at a rate of 3 problems per hour and the last 12 at a rate of 4 problems per hour.
Step-by-step explanation:
6 problems ÷ 2 hours = 3 problems per hour
12 problems ÷ 3 hours = 4 problems per hour
The inside angle for B, which is labeled x is the same as the outside angle of D which is labeled as 72, so we know x = 72.
In a parallelogram two angles next to each other equal 180, so angle A and angle B equal 180.
We know B = 72, so A = 180-72 = 108
Angle A is divided in 2 by angle y, so y = 108/2 = 54
Answers: x = 72
Y = 54
