Answer:
after 10 months
Step-by-step explanation:
Let x be the number of months and y be the amount they still owe.
Sin Ian borrows $1000 from his parents, then the y-intercept b= 1000 since he owes $1000 when x = 0. He pays them back $60 each month The slope is then m = -60 . Substituting in b = 1000 and m = -60 into the slope-intercept form of a line then gives y= mx + b=-60x +1000.
Sin Ken borrows $600 from his parents, then the y-intercept b = 600 since he owes $600 When x= 0. He pays them back $20 per month so the amount he owes decreases $20 each month. The slope is then m = -20 . Substituting in
b= 600 and m = -20 into the slope-intercept form then gives y = mx +b = -20x + 600.
They will owe the same amount when they have the same y-coordinate. Therefore -60x+ 1000= y= -20x+600. Solve this equation for x:
-60x+ 1000 = -20x+ 600
1000 = 40x+ 600
400 = 40x
10=x
They will then owe the same amount after 10 months.
Diameter of the semicircle: D=6 yd*(3 ft / 1yd)→D=18 ft
Circumference of the semicircle: C=pi*D/2
C=pi(18 ft)/2
C=9pi ft
pi=3.14
C=9(3.14) ft
C=28.26 ft
Answer: Fourth option 28.26 ft
Answer:
the answer is w
^2
+
9
w
+
20
Step-by-step explanation:
(5+W)(W+4)
multiply w by w and get w^2 and the 5+w=5w and 4+w=4w and get 9w and then multiply 5*4=20 and then put all together in order of greatest exponent to smallest
w^2+9w+20
