66 + 0.05c < 0.25c
66 < 0.25c - 0.05c
66 < 0.2c
66 / 0.2 < c
330 < c
simple plan checking will be less if there were 331 or more checks written
The length of AB would be 38 units
<h3>How to determine the length AB?</h3>
The attached image represents the missing piece in the question
Considering the triangle BCD;
Calculate the length BC using the following Pythagoras theorem
BC^2 = CD^2 + BD^2
This gives
BC^2 = 10^2 + 8^2
Evaluate
BC^2 = 164
Considering the triangle CBA;
Calculate the length AB using the following Pythagoras theorem
AB^2 = AC^2 - BC^2
This gives
AB^2 = 40^2 - 164
Evaluate
AB^2 = 1436
Take the square root
AB = 38 (approximated)
Hence, the length of AB would be 38 units

Answer:
6
Step-by-step explanation:
5/6 of 30 = ?
5 x
---- = ----
6 36
36 x 5 = 180
180/6 = 30
That means 30 singers are boys.
36 - 30 = 6 (the number of girls)
If you did actually mean to say 13 then replace the 1/3 with 13
