Step-by-step explanation:
I=PRT, P=$1600 R=3% T=1yr
=1600x(3/100)x1

Answer:
Cory bought 6.47 gallons
rate of change is $2.78 per gallon
Step-by-step explanation:
cost of gas per gallon = $2.78
it means that if one buy 1 gallon he will have to pay $2.78 and similary for each increase in 1 gallon of gallon gas he will have to pay $2.78.
Thus, rate of change is cost of gas per gallon as cost to buy gas changes with the change in quantity of gallon.
Let the quantity of gas bought be x gallon.
Total cost for x gallons = cost of gas per gallon*x = 2.78x
Given that total money paid by him is $18
2.78x = 18
x = 18/2.78 = 6.47
Thus, Cory bought 6.47 gallons
rate of change is $2.78 per gallon
Add another triangle to make it a square/rectangle. Then find the perimeter of that. Then divide the answer by 2. That will be the perimeter of the shape.
Answer with Step-by-step explanation:
We are given that a function
Assign each whole number to its largest place value digit.
We have to find the value of x that makes the equation 7 a true statement.
When f(x)=7
Then, the possible values of x are 7,127,27,257,... .
Because f(7)=7
f(127)=7
f(27)=7
f(257)=7
Therefore, the value of x =7,127,257,27,..
