The time required to do a job varies inversely as the number of people working. It takes 5hr for 7 bricklayers to build a park w
ExtremeBDS [4]

<u>Answer</u>

3.5 hours.


<u>Explanation</u>

The first step is to calculate the constant of proportionality.

t ∝ 1/n

t = k/n   Where t = time, K= constant and n = number of people

t = k/n

k =tn

   = 5×7 = 35

The equation becomes;

t = 35/n

for n = 10,

t = 35/10

  t = 3.5 hours.

Which is equivalent to 104<br> ༡/16**?<br> o (10)4x<br> 4(10)3<br> o (10)**<br> O (10)
Hunter-Best [27]

Answer:

I think it is the last one.

Apply radical rule

= (10^1/2)3/4x

Apply exponent rule: (a^b)^c = a^bc

= 10^1/2 . 3/4x

Simplify: 1/2 . 3/4x:  3x/8

= 10^3x/8
