Answer:
57.1mm^2
Step-by-step explanation:
4*4=16
16/2=8mm^2 cross section
(4*3) + (4*3) + (5.7*3) = 41.1mm
8*2=16
41.1+16=57.1mm^2
Answer: Insert a 6. The number divisible by 12 is 14<em><u>6</u></em>4
Step-by-step explanation: Start by dividing 12 into the first two digits.
I am using old-fashioned long division.
<u>1 2</u>
12 ) 14 <u><em>6</em></u>
-<u>12</u>
26. this is the remainder, The next digit has to be a number that when divided by 12 will leave a remainder, that when paired with 4, will be evenly divisible by 12.
6 is that number . When you "bring down" the 6, you will be dividing 26÷12. a 2 goes into the quotient, and in the next step 24 is subtracted from 26; the remainder is 2.
Bring down the 4 and divide 12 into 24. The result is 2 as the quotient. 2 ×12 =24 . 24- 24 is 0
1464 ÷ 12 = 122
For this case we can make the following rule of three:
2 ml -------------> 50cm ^ 2
c -----------------> 325 cm ^ 2
From here, we clear the value of c.
We have then:
c = (325/50) * (2)
c = 13 ml
Answer:
