Digital SAT Math Quiz This quiz randomly generates 22 questions as asked in Digital SAT Math. 1 / 22 The number of roof tops with solar panel installations in 5 cities is shown in the graph below. If the total number of installations is 27,500, what is an appropriate label for the vertical axis of the graph? Number of installations (in tens) Number of installations (in hundreds) Number of installations (in thousands) Number of installations (in tens of thousands) 2 / 22 What is the value of n? 7 8 9 10 3 / 22 For the function g defined below, a is a constant and g(4) = 8. What is the value of g(−4) ? g (x ) = ax2 + 24 8 0 -1 -8 4 / 22 Line ℓ is defined by 5y + 10x = 3. Line n is perpendicular to line ℓ in the xy-plane. What is the slope of line n? -1/2 2 -2 1/2 5 / 22 A pediatrician uses the model below to estimate the height h of a boy, in inches, in terms of the boy’s age a, in years, between the ages of 2 and 5. Based on the model, what is the estimated increase, in inches, of a boy’s height each year? h = 3a +28.6 3 5.7 14.3 9.5 Identify the coefficient of the age variable. The coefficient of a in the equation h=3a+28.6 is 3. 6 / 22 In the figure below, AD = 4, ∠B and ∠D are right angles. What is the length of BC? 2√6 4√2 2√2 2√3 7 / 22 The graphs of the given equations in the xy-plane intersect at the point of (x, y). What is a possible value x? y = 21 y = x2 - 4 -21/5 -5 21 9 8 / 22 What is the value of m+n ? 5 6 7 9 9 / 22 What is the sum of the interior angles in the figure below? 360° 540° 900° 1,080° To find the sum of the interior angles of a polygon, use the formula S = 180(x - 2), with x being the number of sides in the polygon. The polygon above has eight sides, therefore x =8. S = 180(x - 2) = 180(8 - 2) = 180(6) = 1,080° 10 / 22 What is the area of the sector shown below? 7π/3 9π 49π/3 3π 11 / 22 If a / b = 2, what is the value of 4b/a ? 0 1 2 4 12 / 22 Given x = 120 and r = 9, find the area of the sector: 3π 9π 18π 27π 13 / 22 What is the solution (x, y) to the system of equations below? (−5, −2) (3, −8) (4, −6) (9, −6) Multiply 2nd equation with 3, and sum two equation will give us y = -8. Plug y=-8 into any of the equation, will result x = 3 (3,-8) 14 / 22 An event planner is planning a party. It costs the event planner a one time fee of $50 to rent the venue and $37.50 per attendee. The event planner has a budget of $500. What is the greatest number of attendees possible without exceeding the budget? 10 11 12 13 15 / 22 Find value of m + n? 2 3 4 5 16 / 22 If the general inflation rate was 3% last year and John’s salary grew 4%, how much did the purchasing power of his salary change? 4% 3% 2% 1% 17 / 22 Four pizzas are ordered for the children at a party.
