Jerissa is using her calculator. She needs to multiply 8.9 * 0.28, but her decimal point key is not working. Explain how Jerissa could
solve the problem on the calculator without using the decimal point key.

Step by step explanation

Write 5 numbers that round to 740 when rounded to the nearest 10

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x
