Answer:
A) 21.25 + 0.1m <= 60
B) 387
Step-by-step explanation:
I think the problem means to say that the first 1000 text messages are included in the $21.25 plan, and messages above the included 1000 cost $0.10 each.
A)
Let m = number of text messages above 1000.
0.1m is the cost of the messages past the included 1000.
The cost of the plan ($21.25) plus the cost of the messages above 1000, must cost up to $60.
21.25 + 0.1m <= 60
B)
21.25 + 0.1m <= 60
0.1m <= 38.75
m <= 38.75/0.1
m <= 387.5
Answer: 387

Answer:
2.20752 x ![10^{24}](https://tex.z-dn.net/?f=10%5E%7B24%7D)
Step-by-step explanation:
The first thing you have to do is to look for the number of seconds in one year. You have to multiply 365 days by 86,400 seconds.
- 365 days refer to the total number of days per year
- 86,400 seconds refer to the number of seconds per day
Let's solve.
- 365 x 86,400 = 31,536,000 or 3.1536 x
![10^{7}](https://tex.z-dn.net/?f=10%5E%7B7%7D)
<em>Therefore, one year has 3.1536 x </em>
<em> seconds.</em>
Next, you have to know the number of seconds in 10 billion years.
- (3.1536 x
) x (1.0 x
) = 3.1536 x ![10^{17}](https://tex.z-dn.net/?f=10%5E%7B17%7D)
The last step is to multiply the number of seconds in 10 billion years to 7 million tons of mass per second.
- (3.1536 x
) x 7,000,000 = 2.20752 x ![10^{24}](https://tex.z-dn.net/?f=10%5E%7B24%7D)

(thanks for the points)
Answer:
Total amount of pizzas: 6
Total gallons of root beer: 4
Step-by-step explanation:
In 18 hours this is what each one of them could make. (Assuming that none of them can make pizza and brew at the same time)
Pat takes 6h to brew one gallon and make one pizza. So, 18h divided by 6, gives us a total of 3 gallons of beer and 3 pizzas.
Kris takes 10h to brew one gallon and make one pizza. So, 18h divided by 10 gives us 1 and 8h left that Kris could use to make another 2 pizzas. The total for Kris would be 1 gallons of beer and 3 pizzas.
Combined, the totals are:
4 gallons of root beer (3 Pat and 1 Kris) and 6 pizzas (3 each).
