2 and 4 are false
Explain: it could not be certain unless there was 16 green and it is likely that red would be picked as it is the most common
Answer:
Step-by-step explanation:
This is a system of inequalities problem. We first need to determine the expression for each phone plan.
Plan A charges $15 whether you use any minutes of long distance or not; if you use long distance you're paying $.09 per minute. The expression for that plan is
.09x + 15
Plan B charges $12 whether you use any minutes of long distance or not; if you use long distance you're paying $.15 per minute. The expression for that plan is
.15x + 12
We are asked to determine how many minutes of long distance calls in a month, x, that make plan A the better deal (meaning costs less). If we want plan A to cost less than plan B, the inequality looks like this:
.09x + 15 < .15x + 12 and "solve" for x:
3 < .06x so
50 < x or x > 50
For plan A to be the better plan, you need to talk at least 50 minutes long distance per month. Any number of minutes less than 50 makes plan B the cheaper one.
Answer:
The juice left at the end of the day is 1.085 liters.
Step-by-step explanation:
Juice at the beginning of the day: 3.875 liters
Juice drink by Mario during the day: 2.79 liters
Juice left at the end of the day = Juice at the beginning of the day - Juice drink by Mario during the day
= 3.875 - 2.79
= 1.085 liters
First flip the second fraction
4/7 divided by 9/6
Next multiply 4 x 9 which is 36
Then multiply 7 x 6 which is 42
Then divide the fraction 36/42
Which since it's not even it would be in decimal form it would be 0.9
Answer:
34
Step-by-step explanation:
1. Add 6 and 5 and that multiplies with 8 which would be 88
2. Then divide by 4, leaving you with 22.
3. Add that with 6(2), 12, and that gives you 34
