Twice a number (x) is less then 10
Answers
Twice x would be 2 * x, because it's x two times, which would be said as 2x.
Less then 10 would be <10, because the sign (<) is the less than sign and 10 follows it.
So it would be 2x < 10.

How to convert 8.5 hours to hours and minutes
Answers
so 4.25 hrs = 4 hrs and 15 minutes
b. 8.5 hrs.....8 5/10 reduces to 8 1/2.....1/2(60) = 60/2 = 30 minutes
so 8.5 hrs = 8 hrs and 30 minutes
c. 6.2 hrs.....6 2/10 reduces to 6 1/5.....1/5(60) = 60/5 = 12 minutes
so 6.2 hrs = 6 hrs and 12 minutes
d. 10.8 hrs.....10 8/10 reduces to 10 4/5.....4/5(60) = 240/5 = 48 minutes
so 10.8 hrs = 10 hrs and 48 minutes
Final answer:
To convert 8.5 hours to hours and minutes, we use the conversion factor that there are 60 minutes in an hour. Multiplying 0.5 hours by 60 minutes gives us 30 minutes, so 8.5 hours is equivalent to 8 hours and 30 minutes.
Explanation:
To convert 8.5 hours to hours and minutes, we need to understand that there are 60 minutes in one hour. The integer part of 8.5 hours is 8 hours. The decimal part (0.5) represents the fraction of an hour. To find out how many minutes are in 0.5 hours, we multiply by the number of minutes in one hour (60 minutes).
0.5 hour × 60 minutes/hour = 30 minutes.
Therefore, 8.5 hours is equivalent to 8 hours and 30 minutes. This process of conversion makes use of the conversion factors such as 24 hours per day, 60 minutes per hour, and 60 seconds per minute.
For what value of x do the functions f(x)=−52x+4 and g(x)=−12x−4 have the same output?
Answers
g(x) = -12x - 4
To find the solution of the system of equation, we have to just equate the equation to each other.

-52x + 4 = -12x - 4
-52x + 12x = - 4 - 4

Given that 1 meter = 1 x 109 nanometers, what is the diameter of the average cell in the human body, in nanometers? Show your work
The diameter of the average cell in the human body is 1 x 10-5 meters
Answers
Since we are given that:
1 meter = 1 x 10^9 nanometers
We can use the conversion factor:
1 x 10^9 nanometers / 1 meter
Therefore:
diameter = 1 x 10^-5 meters * (1 x 10^9 nanometers / 1 meter)
diameter = 10,000 nanometers
Fiona is serving iced tea and lemonade at a picnic. She has only 44 cups in which to serve the drinks. If x represents the number of glasses of iced tea and y represents the number of glasses of lemonade, which equation represents the number of glasses of iced tea she can serve?
Answers
Answer:
x = 44 - y
Step-by-step explanation:
Fiona is serving iced tea and lemonade at a picnic.
Let x be the number of glasses of iced tea and y be the number of glasses of lemonade.
So the equation represented the total number of glasses of iced tea and lemonade = x + y
Since Fiona has total number of glasses = 44
Therefore, x + y = 44
By solving, x = 44 - y
Equation which represents the number of glasses of iced tea will be x = 44 - y

Last month, Lana sold 35 necklaces a week at $15 each. However, throughout the month, 6 customers returned their necklaces for a full refund due to defective clasps. How much did Lana make selling necklaces last month? (Hint: Assume there were 4 weeks in the last month.)
Answers
To calculate the amount Lana made selling necklaces last month, multiply the number of necklaces sold per week by the price of each necklace. Subtract the number of returned necklaces and multiply the adjusted number by the price to find the total amount.
Explanation:To calculate the amount Lana made selling necklaces last month, we need to multiply the number of necklaces sold per week by the price of each necklace. Lana sold 35 necklaces per week, so for 4 weeks, she sold a total of 35 x 4 = 140 necklaces. However, 6 customers returned their necklaces, so we subtract that from the total: 140 - 6 = 134 necklaces were actually sold. Each necklace was sold for $15, so the total amount Lana made can be found by multiplying the number of necklaces by the price: 134 x $15 = $2010.
How many people must attend the third show so that the average attendance per show is 3000 write an equation too
Answers
The third show must be attended by 3500 people.
To find the number of people that must attend the third show so that the average attendance per show is 3000, we can use the concept of averages.
The average attendance per show is the sum of the attendances divided by the number of shows.
In this case, we have attended 1 show by 2580 people, 2 shows by 2920 people, and the attendance for the third show is x people. So, the equation to represent the average attendance per show of 3000 is:
(2580 + 2920 + x) / 3 = 3000
To solve this equation, we can multiply both sides by 3 to eliminate the denominator and get:
2580 + 2920 + x = 9000
Then, we combine like terms:
5500 + x = 9000
Finally, we subtract 5500 from both sides to isolate x:
x = 3500
Therefore, for the average attendance per show to be 3000, the third show must be attended by 3500 people.
The probable question may be:
How many people must attend the third show so that the average attendance per show is 3000 write an equation too
1 show is attend by 2580 people,
2 show is attend by 2920 people,
3 show is attend by x people.
correct answer is x=3500

In 1 year, how many more hours of sleep does a giant armadillo get than a platypus?
Answers
If the given variables are 127 hours of sleep per week for a Giant Armadillo, and 98 hours of sleep per week for a Platypus, to determine which animal gets the most sleep, first multiply the total hours of sleep of each animal per week to the total number of weeks In a year, which is 52. Once you get the answers, which are 6,604 hours of sleep in a year for the Giant Armadillo and 5,096 hours of sleep in a year for a Platypus. You subtract 6,604 and 5,096 together to get the answer, which is 1,508. Therefore we conclude that that the Giant Armadillo has 1,508 hours more hours of sleep than a Platypus in a Year.

Since 1970, the # (in thousands) of males M and females F attending institutes of higher education can be modeled by: M=0.091t^3-4.8t^2+110+5,000 and F=0.19t^3-12t^2=350t+3,600 where t is the number of yrs since 1970. Write a model for the total # of people attending institutes of higher education.
Answers
The total number of people attending higher education institutions is modeled by T = 0.281t^3 - 16.8t^2 + 460t + 8,600, representing the sum of the models for males and females attending colleges.
Explanation:To answer the student's query regarding the total number of people attending institutes of higher education, we need to create a model that includes both the number of males and females attending as described by their respective equations. The model for the number of males attending college is given by M = 0.091t^3 - 4.8t^2 + 110t + 5,000, and the model for the number of females is F = 0.19t^3 - 12t^2 + 350t + 3,600. To find the total number of students, T, we simply add the two models together: T = M + F.
Therefore, the model for the total number of people attending institutes of higher education is:
T = (0.091t^3 - 4.8t^2 + 110t + 5,000) + (0.19t^3 - 12t^2 + 350t + 3,600)
Combining like terms, we get:
T = (0.091t^3 + 0.19t^3) - (4.8t^2 + 12t^2) + (110t + 350t) + (5,000 + 3,600)
Which simplifies to:
T = 0.281t^3 - 16.8t^2 + 460t + 8,600
This equation represents the total number of students, in thousands, attending institutes of higher education t years since 1970.
