Answer:
11 hours
Step-by-step explanation:
The x pattern goes by adding 2 each time; the y pattern goes by adding 6 each time.
Slope formula: y/x
= 6/2
= 3
The number of tiles would be 3, 9, 15, 21, 27, 33.
The graph would have points at (0,3), (1,9), (2,15), (3,21), (4,27), (5,33).
Infected = itself + itself
Healthy = 200 - infected
y axis = weeks
x axis = # of people
use green for healthy and red for infected
and mark going by weeks
green:
(1, 199)
(2, 198)
(3, 196)
(4, 192)
(5, 184)
(6, 168)
(7, 136)
(8, 72)
(9, -56)
red:
(1, 1)
(2, 2)
(3, 4)
(4, 8)
(5, 16)
(6, 32)
(7, 64)
(8, 128)
(9, 256)
(10, 512)
The length is 9in and the width is 3in
The perimeter is 24in and the area is 27in²
To start we have to make 2 equations with the information that gave us the problem
l = length
w = width
w = l - 6in
l = 3w
we replace l in the first equation with (3w)
w = (3w) - 6in
w - 3w = -6in
-2w = -6in
w = -6in / (-2)
w = 3in
now we replace the value of w in the second equation
l = 3 (3in)
l = 9in
Now that we have the length and width we can calculate the perimeter and the area with the following formulas
p = perimeter
a = area
p = 2w + 2h
p = 2(3in) + 2(9in)
p = 6in + 18in
p = 24in
a = w * l
a = 3in * 9in
a = 27in²
