hrs
<u>Step-by-step explanation:</u>
1st painter:
2nd painter: ![\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D)
1st + 2nd = Together
+
= ![\frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D)
+
= ![\frac{1}{x}(8x)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D%288x%29)
4x + x = 8
5x = 8
x = ![\frac{8}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B5%7D)
= ![1\frac{3}{5}](https://tex.z-dn.net/?f=1%5Cfrac%7B3%7D%7B5%7D)

Answer:
20 students
Step-by-step explanation:
Weight lifting:
8% = 0.08
250(0.08) = 20
15% of £70= £10.5
Expenditure =£24+£10.5=£34.5
Net amount raised =gross amount - Expenditure
=£70-£34.5=£35.5
No they do not have the same number of zeroes
Although the 2 products do seem like they might have the same number of zeroes, 40 x 500 and 40 x 600
both have 3 zeroes before multiplying
if we take the first 2 digits of the 2 numbers being multiplied to get an idea of the answer
if we take 40 x 500 - 4 x 5 = 20
then theres an extra zero added
but if we take 40 x 600 - 4 x 6 = 24
no extra zeroes added to this
so if we finally look at the answers
40 x 500 = 20 000
40 x 600 = 24 000
20000 has 4 zeroes and 24000 has 3 zeroes
so the answer is no they dont have the same number of zeroes
