at the center of a circular pond, there is apole of 11.63 high above the surface of water from a point on the edge of aponf , a man of 1. 62 m high observed the angle of elevation of the top of the pole and found to be 60degree . find the diametre of the pond​

Zoe placed colored blocks on a scale in science class. each block weighed 0.8 ounces. the total weight of all the colored blocks was 12.8 ounces. how many blocks did zoe place on the scale? write and solve an equation to find the answer.

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x

Lines a and b are parallel. what is the value of x? -5 -10 -35 -55
