Answer:
Total amount spent= $32.04
Step-by-step explanation:
If a full tank carries 15 gallons and Irene's car had only 6.1 gallons, it means that it is empty by ; (15-6.1 )= 8.9 gallons.
Therefore , she needs 8.9 gallons to fill the tank.
Cost of gas per gallon=$3.60
Total amount spent to fill the tank would be = # of gallons * cost per gallon
Total amount spent= 
Answer:
0
Step-by-step explanation:
Combine like terms, perform the operations with the coefficients of the variable, then write the variable.
10r - 5r + 3r - 8r
= 5r + 3r - 8r
= 8r - 8r
= 0
Answer:
I think the answer is A, 70 square centimeters
Answer:
A Triangle
Step-by-step explanation:
When you overlap a square in a pentagon you get a triangle
Believe it or not, :), the width of the ribbon needs to be known to get the right answer. If the ribbon had an infinitely small width the ribbon needed would just be the perimeter.
P=2(L+W)
P=2(12+15)
P=54 in
However an infinitely small width is not something that has any practical application. For example, if the width of the ribbon were 1/2 in.
P=2((L+1)+W)
P=2(16+12)
P=56 in So the perimeter increased by 2 in when the ribbon was only 1/2 in wide.
The "infinitely small" width and the perimeter of 54 in is only a decent approximation if the ribbon were a very thin string.
