Width of the rectangle is 10.67 ft
<u>Step-by-step explanation:</u>
Step 1:
Let the width of the rectangle be x. Then length = 2x + 12
Given width + length = 44ft ⇒ x + 2x + 12 = 44
⇒ 44 = 3x + 12
⇒ 32 = 3x
⇒ x = 32/3 = 10.67
Width of the rectangle = 10.67 ft
Answer:
440 students.
Step-by-step explanation:
Given is a table showing the results of a survey.
No of people surveyed = n (say)
No of people who prefer pop music = (5/8) n
(Since given in the table proportion for pop music = 5/8)
But actual studdents who prefer pop music =275
In other words
5n/8 = 275
Cross multiply to solve
5n=2200
divide by 5
n= 440
Thus total people surveyed= 440
Verify:
No of students who prefer Pop music = 440(5/8) = 55(5) = 275
Thus verified
150-110 = 40
rate of change would be -40, the amount withdrawn every month
Answer: son 24 daughter 12
100= total years of age of all ppl in 4years but we want their age now
100=(52+4)+(2x+4)+(x+4)
3x=36
x=12
So daughter is 12 and son is 2x or 24
