Answer:

109

Step-by-step explanation:

line AB is 180 degrees because a circle is 360 degrees and half a circle is 180 degrees.

Add 42 degrees and 29 degrees. 42+29 = 71

Then subtract. 180 - 71 = 109

So therefore $x=109$

Hope this helps:)

Henry is conducting an experiment with 800 bacteria. He found the exponential growth rate to be 2.7% per hour. What is the amoun

joja [24]

Let's formulate an equation first. For exponential growth, we follow the formula. b = 800, r - 0.027. Hence,

y = 800(1+0.027)^t

Then, at t = 21, y will be determined
y = 800 (1+0.027)^21
y = 1399.81 = 1400

Thus, the amount of bacteria present after 21 hours is 1400.
