(a) 28%
(b) 24%
When calculating the total amount of people it come out to 150.
According to the table 42 people smoke. 42/150 is 28%
According to the table 36 people exercise regularly. 36/150 is 24%
The other number is -3.
Step-by-step explanation:
Step 1; First we develop formulae for the given information. A number is added with 3 and the resulting sum is multiplied by 4. This number is then divided by 2 and the quotient is 0. Assume the unknown number is x, then the given information is as follows
The quotient of
is 0. So
= 0.
Step 2; Now we solve the above equation. The denominator is taken to the RHS and the RHS remains zero.
= 0, 4(x+3)= 0, 4x+ 12 = 0, 4x = -12, x =
= -3.
So the other number is -3.

$180
Step-by-step explanation:
<em>Just calculate the perimeter.</em><em>.</em><em>.</em>
4 yards = 12 feet
<em>And add everything up-</em>
18+10+(18-10)+12+12
=60 feet
60 x 3 =<u>180</u>
<em>There you go</em>
