The perimeter and area of a rectangle are (5,6) and (6,5).
The perimeter method for a rectangle states that P = (L + W) × 2, where P represents perimeter, L represents length, and W represents width. when you are given the size of a square form, you may simply plug within the values of L and W into the formula that allows you to clear up for the fringe.
A perimeter is a closed course that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional period. The perimeter of a circle or an ellipse is known as its circumference. Calculating the perimeter has several practical programs.
The perimeter P of a rectangle is given by means of the method, P=2l+2w, in which l is the period and w is the width of the rectangle. The place A of a rectangle is given with the aid of the components, A=lw, wherein l is the length and w is the width.
The perimeter of the rectangle:
P=2l+2w=22
divide 2 into both sides
l+w=11 -------------> (1)
w=11-l
Area of the rectangle:
l*w=30
l(11-l)=30
11l-l^2-30=0
l^2-11l+30=0
By factor method,
(l-5)(l-6)=0
l=5,6.
Substitute this value in w,
l=5 implies w=6
l=6 implies w=5
There we have two solutions.
The length and breadth of the rectangle is
(5,6) and (6,5).

Answer:
0.4114
0.0006
0.1091
0.1957
Step-by-step explanation:
<u>Given: </u>
p = 0.7 n = 10
We need to determine the probabilities using table , which contains the CUMULATIVE probabilities P(X 
x).
a. The probability is given in the row with n = 10 (subsection x = 3) and in the column with p = 0.7 of table:
P(X 3) = 0.4114
b. Complement rule:
P( not A) = 1 - P(A)
Determine the probability given in the row with n = 10 (subsection x = 10) and in the column with p = 0.7 of table:
P(X 10) = 0.9994
Use the complement rule to determine the probability:
P(X > 10) = 1 - P(X 10) = 1 - 0.9994 = 0.0006
c. Determine the probability given in the row with n = 10 (subsection x = 5 and x = 6) and in the column with p = 0.7 of table:
P(X 5) = 0.8042
P(X 6) = 0.9133
The probability at X = 6 is then the difference of the cumulative probabilities:
P(X = 6) = P(X 6) - P(X 5) = 0.9133 — 0.8042 = 0.1091
d. Determine the probability given in the row with n = 10 (subsection x = 5 and x = 11) and in the column with p = 0.7 of table:
P(X 5) = 0.8042
P(X 11) = 0.9999
The probability at 6 X 11 is then the difference between the corresponding cumulative probabilities:
P(6 X 11) = P(X 11) - P(X 5) = 0.9999 — 0.8042 = 0.1957
Answer:
ok the formula is Width= P
/2﹣l
68/2-18=16
the width is 16
Step-by-step explanation:
Step 1:
Find the difference between the two numbers.
$2.40-$1.44= $0.96
Step 2:
Divide by the original number.
$0.96/1.44= 0.667
Step 3:
Multiply by 100 to find percent increase.
0.667 * 100= 66.7% rounded to one decimal place or 67% rounded
Hope this helped! :)
