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:
0.04705882352
Step-by-step explanation:
Yeah, I don't really have an explanation, sorry. I guess you just turn them both into decimals and multiply afterwards.
By using an online graphing calculator, the solution to this system of inequalities are plotted in the image attached below.
<h3>How to graph a system of inequalities?</h3>
An inequality is a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:
- Less than or equal to (≤).
- Greater than or equal to (≥).
Given the following system of inequalities:
y ≤ 1/3x ⇒ y - 1/3x ≤ 0
y - 2x < 4
By using an online graphing calculator, the solution to this system of inequalities are plotted in the image attached below.

<u>Complete Question:</u>
Graph the following system of inequalities.
y ≤ 1/3x and y - 2x < 4
Answer:
<b = 133
<c = 47
Step-by-step explanation:
<b and 133 are vertical angles and vertical angles are equal
<c and 133 form a straight line so they add to 180
<c+133 = 180
<c = 180-133
<c =47
We know the opposite side (10) and the adjacent side (7), so we can use tangent to find angle B. Since tan = opposite side/adjacent side, we can set up this equation: tan(B) = 10/7. We can get B on its own by making the equation this:

Now, we plug this into our calculator to get:
B = 55°, so angle B is 55°.
