This equation shows how the time required to complete an online shopping transaction is related to the number of products being purchased. t = 16p The variable p represents the number of products, and the variable t represents the time required to complete the transaction. If it takes 16 seconds to complete a transaction, how many products are being purchased?

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
