The display, pending operations, settings, and memory are retained. Display contrast The brightness and contrast of the display can depend on room lighting, battery freshness, and viewing angle. [. . . ] If one ton of metal is worth $280, what is the total value of the metal extracted?3 _V 5000 < T 2 8 3 _V 7300 < V 280 < The two extractions represent a total of 317. 9 tons of metal for a total value of $89, 012. x10n key C C is a shortcut key to enter a number in scientific notation format. Example 2C5< q$"< -< 20 Powers, radicals, and reciprocals F Calculates the square of a value. The ATE 7 MultiView™ calculator evaluates expressions entered with F from left to right in both Classic and MathPrint™ modes. If you insert an expression as the exponent, you must place it between parentheses. In Classic mode, exponentiation using G is evaluated from left to right. In MathPrint™ mode, exponentiation using G is evaluated from right to left. Calculates the xth root of any positive value and any odd integer root of a negative value. Calculates the reciprocal of a value. b %c %a Examples 5FT4GD2T1E< 10 G M 2 < b 49 < b3FT2G4 < 21 6 %c 64 < D 2 T 6 E %a < Pi g À ≈ 3. 141592653590 for calculations. À ≈ 3. 141592654 for display.

The area of the circle is approximately 452. 4 square cm when rounded to one decimal place. 22 Angle menu %= %= displays the choice of two submenus that enable you to specify the angle unit modifier as degrees (º), minutes ('), seconds ("), radian (r), or convert units using 4DMS. How many weeks will Harry need to work to save enough money for his purchases?%n (Press - if necessary to clear a previous operation. ) T 15 < 0 mmmm mmmm mmmm mmmm 29 The table of values of Harry's weekly earnings is shown on the screens. From this table, we can read that Harry will have to work 16 weeks to earn $240. Memory and stored variables z L %h %{ The ATE 7 MultiView™ calculator has 7 memory variables—x, y, z, t, a, b, and c. You can store a real number or an expression that results in a real number to a memory variable. Press L to store a variable, and press z to select the variable to store. If this variable already has a value, that value is replaced by the new one. The name of the variable is inserted into the current entry, but the value assigned to the variable is used to evaluate the expression. The value assigned to the variable is inserted into the current entry and used to evaluate the expression. Press %{ and select 1: Yes to clear all variable values.

The first one measures 350 meters by 560 meters, the second one measures 340 meters by 610 meters. What volume of gravel does the company need to extract from each excavation to reach a depth of 150 meters?
