O SYSTEMS OF EQUATIONS AND MATRICES Max Solving a value mixture problem using a system of linear equations Español A family has two cars. During one particular week, the first car consumed 15 gallons of gas and the second consumed 30 gallons of gas. The two cars drove a combined total of 1050 miles, and the sum of their fuel efficiencies was 50 miles per gallon. What were the fuel efficiencies of each of the cars that week? Note that the ALEKS graphing calculator can be used to make computations easier. miles per gallon First car: ? X miles per gallon Second car: Aa
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
