Kala call lasted for 0.36 minutes
<em><u>Solution:</u></em>
Given that Kala purchased a prepaid phone card for $15
Long distance calls cost $12 a minute using this card.
If the remaining credit on her card is $10.68
To find: Number of minutes her call lasted
Let "x" be the number of minutes her call lasted
Cost of 1 minute = $ 12
Total balance = $15
Remaining balance = $ 10.68
So we can frame a equation as:
Total balance = Remaining balance + Cost of 1 minute x number of minutes her call lasted

So her call lasted for 0.36 minutes
Answer:
No.
Step-by-step explanation:
According to the law of exponent:-

Therefore:-

mˆDG=151∘∘
An arc’s length means the same commonsense thing length always means — you know, like the length of a piece of string
Answer:
y = -1/2x + 17/2
Explanation:
y = 2x + 1 is in slope intercept form
in the equation y = mx+b, m is the slope, and in the equation m =2
the slope of a perpendicular line is the negative reciprocal of the other slope.
slope of perpendicular= -1/m = -1/2
y = -1/2x + b
now find b by substituting in (1,8) into the partial equation
8 = -1/2 + b
b = 8+ 1/2
b = 17/2
