<u>The dependent and independent quality in the given situation:</u>
The given situation is that a long-distance telephone call cost increases with the number of minutes of the call. The two variables are dependent and independent.
The independent variable here in the given situation is the number of minutes of the call since it can be changed as much as we want
The dependent variable is the cost of the long-distance call as it relies on the number of minutes of the call. The cost increases when the number of minutes increases.
Answer:
∠ QRS = 43°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4n - 9 + 5n - 18 + 90 = 180, that is
9n + 63 = 180 ( subtract 63 from both sides )
9n = 117 ( divide both sides by 9 )
n = 13
Thus
∠ QRS = 4n - 9 = 4(13) - 9 = 52 - 9 = 43°
∠ RSQ = 4n - 18 = 4(13) - 18 = 65 - 18 = 47°
Answer:
45/r
Step-by-step explanation:
You're just doing 45 divided by r.
Answer:
(x-5)(x+6)=0
Step-by-step explanation:
hehe i doing the smae unit rn.
if a=1 (which it does do ac factoring)
you need two numbers that multiply to -30 and add to 1. those numbers are 5 and -6.
substitute 1x for -5x + 6x.
group the numbers into pairs and find their gcf's
x(x-5) 6(x-5)
since the parenthesis r the same yo only need one. Now you need to put x and 6 in a parenthesis.
FINAL: (x-5)(x+6) hope this helps
Step-by-step explanation:
Let A(x) be the area function of given rectangle.
Radius of circle = 7x
Therefore, length of rectangle = 14x
Width of rectangle = 7x
Let P(x) be the Perimeter function of given rectangle.
