Answer:
He has 45 kids now.
Step-by-step explanation:
Let the required number is 2x ,
According to the condition,
➡ 10 times the sum of half of 2x and 6 = 8

Therefore the value of x is -5.2
And, required number is -5.2
the picture in the attached figure
we know that
area of the triangle is equal to

in this problem
A=47 in²
b=x
h=x
so

therefore
the answer is
x=9.7 in
<u>Answer:</u>
0.0005 oz
<u>Step-by-step explanation:</u>
Usually, the greatest number that is allowed for approximation, assuming that the number itself is obtained by approximation, is the greatest possible error of it.
It is normally half the place value of the last digit in a number.
Like here we have
oz which is equal to
oz. The last digit is 5 which is at the thousandth place (0.001) so the greatest possible error for this would be its half.
= 0.0005 oz
