Answer:
-20.
Step-by-step explanation:
(10)9 - (10)11
By the Distribute Law this is :
10(9 - 11)
= 10 * -2
= -20.
30 mph because if you do 60x 3 and 50x3, you get 180 and 150, then you subtract 180-150 and you get 30
First we have to work out the area of the trapezoid using the formula;
1/2 (a+b) h
The height is 16ft, and a = 24ft, and b = 15ft
Put this into the formula
1/2 (24 + 15) 16
1/2 39 * 16
39 * 8 (you can halve the 16)
= 312 ft squared
Now we simply multiply the area by the cost per square foot to get our answer.
312 * 0.79 = $246.48

Answer/Step-by-step explanation:
a. % of people who smoke = no. of people who smoke ÷ total no. of people surveyed × 100
Total no. of people who smoke is given = 4 + 36 = 40
Total people surveyed = 200
% of people who smoke =
a. % of people who do not exercise regularly = no. of people who do not exercise regularly ÷ total no. of people surveyed × 100
Total no. of people who do not exercise regularly = 36 + 134 = 170
Total people surveyed = 200
% of people who smoke =
