Let x represent the shorter sides, then 2x + 1 would represent the longer sides. There are four short sides and two long sides. The perimeter is 162 cm. The equation: 4x + 2(2x + 1) = 162 4x + 8x + 2 = 162 8x + 2 = 162 Subtract 2 from both sides. 8x = 160 Divide both sides by 8. x = 20 The shorter sides are 20 cm in length. The longer sides are 2x + 1, or 41 cm in length. Check: 4 * 20 + 2 * 41 = 162 80 + 82 = 162 162 = 162, values check.

Answer:
Step-by-step explanation:
An arithmetic sequence is generally given as:
f(n) = a + (n - 1)d
where a = first term and f(n) = nth term, d = common difference
The explicit formula given is:
f(n) = 11 + 22(n - 1)
The recursive formula is made of two statements, the first term and the formula showing how successive terms are related.
Mathematically, it is given as:
Therefore, the recursive formula is:
The value of r in the given expression is 5.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given that the expression as;
75 = 15r
Now we need to find the value of r.
Therefore, we wil divide the 15 both side;
r = 75/ 15
r = 5
Hence, the value of r in the given expression is 5.

Answer: 1/4
Step-by-step explanation:
From the letter a), we have 8 possible options. From these options, we have 2 that have turkey and ketchup (WTK and BTK), so the probability is the number of options we want over the total number of options:
Fraction of turkey and ketchup is = 2/8 = 1/4
