Note that
- 12=2·2·<u>3</u>;
- 20=2·2·5;
- 36=2·2·<u>3</u>·3.
The common factors of these three numbers are 2, 2. Also numbers 12 and 36 have one more common factor <u>3</u>, then the least common multiple is
LCM(12,20,36)=2·2·<u>3</u>·5·3=180 sec=3 min (here first you write all common factors between all three numbers, then between two numbers and at last all remaining factors).
Answer: all three experiments will need to be checked after 3 minutes passed, then after 6 minutes passed, then after 9 minutes passed and so on.
Answer:
Step-by-step explanation:
Let the five consecutive integers be (x - 2 ) , (x - 1) , (x) , (x + 1) , (x + 2)
(x - 2 ) + (x - 1) + (x) + (x + 1) + (x + 2) = 110
x - 2 + x -1 + x + x +1 + x + 2 = 110
5x = 110
x = 110/5
x = 22
The consecutive numbers are: 20,21,22,23,24
Find attached a graph that I constructed.
To do that graph I used Excel.
First I did a table with this set of points:
<span><span><span>height presuure
</span>
<span>
miles psi
</span>
<span>
0
14,7
</span>
<span>
<---- initial data
3.6 7.35
</span>
<span>
<--- increase hegiht 3.6 miles => half pressure
7.2
3.675
</span>
<span>
<---- second increase of 3.6 miles in height
10. 8
1.8375
</span>
<span>
<---- third increase of 3.6 miles in height
14.4
0.91875

Answer:
USE A CALCULATOR LIKE THE REST OF USE
Step-by-step explanation:
Answer:
5/6
Step-by-step explanation:
(2/3) / (4/5) = (2/3) * (5/4) Rock times roll, which means keep the first fraction the same ("rock"), change the division to "times", and "roll" the second fraction.
= (1/3) * (5/2) Simplify the 2 and the /4 since they are both even
= (1*5)/(2*3) Multiply the numerators together and the denominators together
= 5/6
