You can draw a picture and you can find your answer but the answer is 1 1/3 by the way
Answer:
<em>y=0.10(t)+0.25 </em>
<em>27 minutes and 30 seconds </em>
Step-by-step explanation:
We know that you start with 25 cents as a service fee, this is for making the call. For each minute you talk, 10 cents are added. Multiply the number of minutes spent by 10 cents a minute for the cost based on the call. Then add the 25 cents service fee.
If you talked for 5 minutes:
y=0.10(5)+0.25
y=0.50+0.25
y=0.75
75 Cents
For three dollars, you would plug in 3 for y
3.00=0.10(t)+0.25
-0.25 -0.25
2.75=0.10(t)
divide both sides by 0.10 to get
27.5=t
You can talk for 27 minutes and 30 seconds
27 minutes

Answer:
A fair six-sized die is rolled. Find the probability of getting at least a 4.
There are 6 outcomes and three of them are 4, 5 or 6, so the probability of greater than or equal to 4 is 3/6=½.
Answer:
3) The function's leading coefficient is negative.
Explanation:
(1) Is not the answer because when x = 3, f(x) = 0.
(2) Is not the answer because when f(x) = -3,
x = 0.
(4) Is also not the answer because the y-values on both sides of (1, -4) are mirroring each other.
Therefore,
(3) is the answer, by elimination, but also because there is not proof of the leading coefficient being negative, as we don't see the original equation.
I hope this helped! :)
(3/4)*0.88=0.66
(1/3)*6.60=2.20
totail: 0.66+2.20=2.80
