First, write an equation system based on the problem
An equation for "the perimeter of a rectangle is 70 in" can be written as following
∴ 2l + 2w = 70 <em>(first equation)</em>
An equation for "the length is 11 in more than its width" can be written as following
∴ l = w + 11 <em>(second equation)</em>
Second, solve the equation by substitution method o find the dimension of the rectangle.
Substitute/plug l as (w+11) into the first equation
2l + 2w = 70
2(w + 11) + 2w = 70
2w + 22 + 2w = 70
4w + 22 = 70
4w = 70 - 22
4w = 48
w = 48/4
w = 12
The width of the rectangle is 12 in
Substitute w with 12 to the second equation
l = w + 11
l = 12 + 11
l = 23
The length of the rectangle is 23 in
Third, find the area of the rectangle
a = l × w
a = 23 × 12
a = 276
The area of the rectangle is 276 in²
Answer:
Step-by-step explanation:
TU , UV , VW, TW are the sides
As points T and U have same x-coordinate, length of TU will be given by the difference of y-coordinate
TU = 9 - 7 = 2 units
As points U and V have same y-coordinate, length of UV will be given by the difference of x-coordinate
UV = 5 - 2 = 3 units
As points V and W have same x-coordinate, length of VW will be given by the difference of y-coordinate
VW = 9 -7 = 2 units
As points W and T have same y-coordinate, length of WT will be given by the difference of x-coordinate
WT = 5 - 2 = 3 units
TU = VW = 2 units
UV = WT = 3 units
So, TUVW is a rectangle
Area = length *width = 3* 2 = 6 square units
Perimeter = 3 + 2 + 3 + 2 = 10 units
Answer:
x=k+c over 7
Step-by-step explanation:
7x-c+c=k+c
7x=k+c
divide both sides by 7
Answer:
Sample size should be less than 85
Step-by-step explanation:
Sample size should be less than 85
Step-by-step explanation:
To use the infinite standard deviation formula, n has to be <= (0.05)(1700)
n <= 85
So the sample size has to be less than 85
In another way too,
n = sample size
N = population size
For population, we multiply correction factor to the infinite standard deviation
F is <= 0.05
n<0.05x1700
n<85
Sample size should be less than 85
