Given that Jordan has a new puppy and she wants to put a fence around part of her yard to cover an area of 200 square feet.
Now we have to find what dimensions (length x width) should she make the rectangular area. None of the length or width are given so there can be lots of answers.
Since area is rectangular and we know that rectangle has different value of length and width so we just need to find two factors of given area 200 square feet.
For example 20 times 10 is 200.
So the dimension of the rectangular area will be:
Length = 20 feet and width = 10 feet
Now perimeter of the rectangle is given by formula:
Perimeter = 2(length+width) = 2(20+10)=2(30)=60
Hence perimeter is 60 feet.
Its the first one: Letter A
Answer:
a) 4 products
b) 10 products
Step-by-step explanation:
When completing an online shopping transaction, a typical shopper takes 5 seconds to select each product and another 28 seconds to complete the check-out process.
For 1 product, the total time =
5 seconds + 28 seconds = 33 second.
We can derive an equation
Total time of transaction = 5x + 28
Where x is the number of products you are selecting
a) If it takes 48 seconds to complete a transaction, how many products are being purchased?
Total time = 5x + 28
48s = 5x + 28
5x = 48 - 28
5x = 20
x = 20/5
x = 4 items
b) If it takes 80 seconds to complete a transaction, how many products are being purchased?
Total time = 5x + 28
80s = 5x + 28
5x = 80 - 28
5x = 52
x = 52/5
x = 10 items
In whole number = 10 items
