Answer:
Bottom part = 10 * 12 = 120 square centimeters
Top part 8 * 6 = 48 square centimeters
Total Area = 168 square centimeters
Step-by-step explanation:
Subtract the numbers.
10 - 8 = 2
Divide it to the smaller number:
2 / 8 = 0.25
Multiply by 100:
0.25 * 100 = 25%
Answer:
see below
Step-by-step explanation:
6+9x^2
Rewriting in decreasing powers of x
9x^2 +0x + 6
ax^2+bx+c
a = 9
b =0
c = 6
It took 3 days to complete a work by 10 people.
<h3>What is Efficiency?</h3>
The efficiency is the output of the work which we divide by the work input and then express it in a percentage form.
Here, Efficiency of 1 person to complete a piece of work in 30 days is 1/30.
The number of days to complete the work = n days
Number of person to complete the work = p.
Now, according to question
Number of days to complete the work by 10 people = 30 / 10
= 3 days.
Thus, it took 3 days to complete a work by 10 people.
