Amath test has 12 multiplication problems and 24 division problems. what is the ratio value of division problems to total problems?

Step-by-step explanation:

Total problems=  multiplication problems +  division problems

  = 12 +24 = 36

Ratio value of division problems to total problems = 24/36 = 2/3

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
