The answer is 345 students.
I did reverse math(i don't remember the name)
138/.4=345
Now check it:
345*.4=138
I hope I helped somehow!
Answer:
22.5%
Step-by-step explanation:
1 person is doing 0.025 of the work. What is that in percent??
<em>We convert decimal to percentage by multiplying by 100 and sticking the "%" sign.</em>
<em>So,</em>
0.025 * 100 = 2.5%
Hence, 1 person is doing 2.5% of the total 25% of the work alloted to 4 persons.
The other 3 would do rest of the work, that would be:
25% - 2.5% = 22.5% of the work (rest 3 person would be)
First, you have to find the LCD. The LCD of 4 and 7 is 28, so you rewrite the fraction:
7/28
4/28
Then you add them.
52 is the answer because there are 12 inches in a foot
your answer would be D.
4a (4a) + 4a (-5b) + 5b (4a) + 5b (-5b) it is simplified to 16a^2-25b^2
