Answer:
36 feet
Step-by-step explanation:
3ft is 1 yard so you would multiply the 12 yards by 3 making 36.
Answer: 495 bacteria in 2 minutes.
Step-by-step explanation:
We would apply the formula,
y = ab^t
Where
a represents the initial amount of bacteria.
t represents the doubling time.
From the information given
a = 10
t = 15 seconds
Since after 15 seconds, the amount of bacteria multiplies by 2, then
y = 2 × 10 = 20
Therefore
20 = 10 × b^15
Dividing through by 10, it becomes
2 = b^15
Raising both sides of the equation by 1/15, it becomes
2^(1/15) = b^15/15
b = 1.047
The equation becomes
y = 10(1.047)^t
For t = 2 minutes(2 × 60 = 120 seconds), then
y = 10(1.047)^120
y = 495 bacteria
Answer:
<h2>Let the number is = X </h2><h2>Two thirds of the number = 2x/3</h2><h2 /><h2>According to the problem given,</h2><h2>x+ 2x/3 = 55</h2><h2>( 3x + 2x ) /3 = 55</h2><h2>5x /3 = 55</h2><h2>x = ( 55 × 3 ) /5</h2><h2>x = 11 × 3</h2><h2>x = 33 </h2>
<h2>Therefore,</h2><h2>Required number = x = 33</h2>
Answer: 8
Step-by-step explanation:
24 pounds for every 3 acres all you have to do is divide and you get 8
24 divided by 3 = 8 =)
Hope this helps
So picture a 8feet long board, and you basically cut it into 3 equal pieces as it says. so you should set it up as 8/3 which is 2.6666666. so you can round that up by 2.67 per each equal pieces.
