Do you mean as a fraction?
First you need to find the cost of 1 can of nut:
let x represent the number of cans
4x=$9
divide both by 4
x=2.25
meaning 1 can costs $2.25
$2.25×7
=$15.75
meaning the cost of 7 cans is $15.75
Answer:
none
Step-by-step explanation:
All are rational numbers because each number can be expressed as the quotient of 2 integers:
100÷1
36÷1
27÷1
47÷1
Area = 50.27 ft squared
area of circle = πr^2
a = π(4^2)
a = π16
a = 50.27
π = about 3.14159
3.14159(16) = 50.26544 --> 50.27
