Answer: 1.26
Step-by-step explanation:
Since he bought a 18 gallon tank of gas with regular fuel for 55.08.
The station across the street sold regular fuel for 2.99 per gallon. A 18 gallon tank will cost:
= 18 × 2.99
= 53.82
The amount that could have been saved would be:
= 55.08 - 53.82
= 1.26
For the the first problem that looks like a bow-tie, we don't have enough information to say if the triangles are congruent or not. We have a pair of sides and a pair of angles (the vertical angles) that are congruent, but that's about it. We can't use SSS or SAS, so that's why the answer is "not possible" for this problem.
As for the second problem, we will use SSS because we have three sets of congruent pairs of sides. The tickmarks tell us which sides pair up. The third pair of sides is the shared segment in the middle, or the diagonal of the parallelogram. We will not use SAS because we don't know anything about the angles. So we use SSS only.
Answer:
Domain would be all real numbers

To prove a rhombus you need to show that the sides are congruent and the diagonals are perpendicular.
Sides:
≅ ≅ ≅
Diagonals:
Use the slope formula:
= -1
= 1
Slopes are opposite reciprocals so they are perpendicular.
***************************************************************************
All of the sides are congruent and the diagonals are perpendicular so RMBS is a rhombus.
