<em>Answer:</em>
<em>Can be found below</em>
<em>Step-by-step explanation:</em>
<em>Part A:</em>
<em>So we know that the bacteria doubles every (30) minutes.</em>
<em>2000 times 2 equals 4000 (30 minutes)</em>
<em>4000 times 2 equals 8000 (1 hour)</em>
<em>Answer for Part A:</em>
<em>8000 bacteria</em>
<em>Part B:</em>
<em>Now we do this function 2000(2)^14 (30 minutes long)</em>
<em>Answer to Part B: </em>
<em>I believe the answer is 32,768,000 (Please correct me if I'm wrong) </em>
<em>Hope I could help!! Have a great day/night!</em>
<em>Any constructional messages are greatly appreciated!!</em>
Answer:
distance=rate*time
2520=(r)(3)+(r+90)(3) (they both travel for 3 hours)
2520=3r+3r+270
2520-270=6r
2250=6r
r=2250/6
r=375 mph
r+90=375+90=465 mph
Step-by-step explanation:
Answer:
-10/3 is the answer
Step-by-step explanation:
Given are two complex numbers as
Recall Demoivre theorem as
(cosA+isinA)(cos A+isin B) = cos(A+B)+isin(A+B)
Hence here we have sum of angles as
A+B = 63+117 =180
=
Since sin180=0 and cos 180=-1
Answer:
Humans breathe about 300 liters of air in 25 minutes
Write the decimal number as a fraction
(over 1)
0.87 = 0.87 / 1
Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's
Numerator (N)
N = 0.87 × 10 × 10 = 87
Denominator (D)
D = 1 × 10 × 10 = 100
N / D = 87 / 100
Simplifying our fraction
= 87/100
