Answer:
After 17 hours there will be about 143 bacteria.
Step-by-step explanation:
Given that in a lab experiment, 80 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 19 hours, to determine how many bacteria would there be after 17 hours, to the nearest whole number, the following calculation must be performed:
80 x ((2/19) x 17) = X
80 x (0.1052 x 17) = X
80 x 1.7894 = X
143.15 = X
Thus, after 17 hours there will be about 143 bacteria.
Answer:1800 words
Step-by-step explanation:
Multiply how many words per minute she types by how many minutes she types. In this case 60x30=?. The easy way to do this is drop the 2 zeros and do 6x3=18. In the original equation we dropped the 2 zeros. Now we add them back on the back of the 18 and get 1800.
