Answer:
It would take 19 hours and 36 minutes until there are 1040 bacteria present.
Step-by-step explanation:
Given that in a lab experiment, 610 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 23 hours, to determine how long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present, the following calculation must be performed:
610X = 1040
X = 1040/610
X = 1.7049
2 = 23
1.7049 = X
1.7049 x 23/2 = X
39.2131 / 2 = X
19.6 = X
100 = 60
60 = X
60 x 60/100 = X
36 = X
Therefore, it would take 19 hours and 36 minutes until there are 1040 bacteria present.
Answer:Marcus jogged 7 miles while Elena jogged 8 miles.
Step-by-step explanation:
x + (x+1) = 15
2x+1=15
putting like terms together we get:
2x=15-1
2x=14
hence
x=14/2 = 7miles
therefore we conclude that Marcus jogged 7 miles while Elena jogged 8 miles.
Answer:
C. V = π(2.5)²h
Volume = 19.6h
Step-by-step explanation:
Radius (r) of cylinder = ½ of 5 = 2.5 in.
Height (h) = h in.
Volume of a cylinder = πr²h
Equation that can be used to find B:
Plug in the values into the volume formula
V = π(2.5)²h
Volume = 19.6h
