Answer:
132
Step-by-step explanation:
Divide it into 2 shapes : a triangle and a rectangle.
The triangle's base length is 20-(8+6) = 6
The height is 10-6 = 4
The triangle's area = 6*4/2 = 12
The rectangle's area is 6 * 20 = 120
Add the two together, and you get 12+120 = 132
Answer : The total number of respondents who took the survey are, 40
Step-by-step explanation :
As we are given that in a survey, 75% of respondents said that they watch TV for one hour each day.
Let the total number of respondents who took the survey be, 'x'
Number of respondents watch TV for one hour each day = 30
The % of the respondents said that they watch TV for one hour each day = 75%
By solving the term 'x' we get:
Thus, the total number of respondents who took the survey are, 40
One marker would cost approx. $0.03
The answer is D, (x + 1) (x + 2) (x - 3)
