A team of scientists estimate the current number of butterflies in a park to be 20 thousand. The butterfly population is expected to increase at a rate of 4% per year. Which equation models the number of butterflies, in thousands, in the park after n years? A. 0.04(20)n B. 20(1.04)n C. 1.04(20)n D. 20(0.04)n
Answers
Answer:
Option B is the correct answer.
Explanation:
Current number of butterflies in the park = 20 thousand.
Rate of increase of butterfly population = 4% = 0.04
The population of butterfly after 1 year = 20+0.04*20 = 20*1.04
The population of butterfly after 2 years = 20*1.04 + 20*1.04*0.04 = 20*1.04*1.04
The population of butterfly after 3 years = 20*1.04*1.04 + 20*1.04*1.04*0.04 = 20*1.04*1.04*1.04
So, population of butterfly after n years = 20*(1.04*1.04*1.04* .... n times)
[tex]= 20*1.04^n[/tex]
Option B is the correct answer.

519 divided by 6 and 915 divided by 7 and 439 divided by 7 and 812 divided by 9 which one does not have a two digit quotient.
Answers
519/6=86.5
915/7=130.7142
439/7=62.7142
812/9=90.2222
so i think its the 1st on but i may be wrong.
In the given sets of divisions, 812 divided by 9 is the one that does not yield a three-digit quotient when considering only whole numbers. All other division operations yield a three-digit quotient.
Explanation:Let's start by dividing each number step by step. When we divide 519 by 6, we get 86.5, and when we divide 915 by 7, we get 130.71428571428572. Next, when we divide 439 by 7, we get 62.714285714285715, and finally when we divide 812 by 9, we get 90.22222222222223.
In this case, a quotient is the result obtained from division. We're asked to identify the operation which does not yield a two-digit quotient. Here, all the separate division operations give us a quotient that is a numerical value with more than two digits. However, when you consider whole numbers only, 812 divided by 9 gives us a two-digit quotient (90), while all other division operation results are three-digit numbers.

: student council is selling tickets to the fall ball dance. Tickets cost $6.00 per person , or $10 per couple. To cover the expenses required, they need to make at least $1,450.

This basically says that the total money made from tickets will be gretarr than or equal to $1450.
To model the situation with a linear inequality, represent the number of individual tickets sold as x and the number of couple tickets as y. The inequality is 6x + 10y >= 1450, signifying that the revenue from individual and couple ticket sales needs to be at least $1,450.
Explanation:To write a linear inequality to model the student council ticket sales, let x represent the number of individual tickets sold, and y represent the number of couple tickets sold. The tickets cost $6.00 per individual and $10.00 per couple. The council needs to make at least $1,450 to cover the expenses of the fall ball dance.
To derive the inequality, we consider the revenue generated from selling individual tickets (x tickets × $6.00 per ticket) plus the revenue generated from selling couple tickets (y tickets × $10.00 per ticket) should be at least $1,450:
6x + 10y ≥ 1450

To lose one pound of fat, a 200-pound person must burn 3,500 calories. If that person burns 180 calories by walking for 30 minutes, how many hours and minutes does the person have to walk to lose two pounds? Round your answer to the nearest minute. A. 53 hours 38 minutes B. 38 hours 53 minutes C. 19 hours 27 minutes D. 39 hours
Answers
For this case we have:
You lose 180 calories by walking 30min, that is:
180cal ---------> 30min
If to lose 1 pound of fat, the person should burn 3500 calories, to lose 2 pounds should burn twice the calories, that is, 7000 calories.
You want to know how long it takes to burn 7000 calories, knowing that they burn 180 in 30min. So:
180cal ---------> 30min
7000cal -------> x
Where x represents the time that must be used to burn the 7000 calories.
Resolving we have:
[tex]x = \frac{(7000cal * 30min)}{180cal}\\[/tex]
[tex]x = 1166.7min\\[/tex]
If 1h has 60min, then:
[tex]x = \frac{ (1166.7min * 1h)}{60min}\\[/tex]
[tex]x = 19.44h\\\\x = (19h + 0.44h)\\[/tex]
0.44h equals [tex]0.44 * 60min = 26.4min\\[/tex]
Thus, for the person to burn 7000 calories and lose 2 pounds, he must walk [tex]x = 19h + 26.4min[/tex].
Answer:
[tex]x = 19h + 26.4min\\[/tex]

If a movie starts at 7:10 and ended at 9:05 how long was it
Answers
1 hour 55 minutes
break the time down into hours and minutes
7 : 10 → 8 : 00 = 50 minutes
8 : 00 → 9 : 00 = 1 hour
9 : 00 → 9 : 05 = 5 minutes
adding 1 hour + 50 minutes + 5 minutes = 1 hour 55 minutes
The movie lasted for a total of 115 minutes, which is calculated by adding the one hour between 7:10 and 8:10 to the additional 55 minutes between 8:10 and 9:05.
To calculate the duration of a movie that starts at 7:10 and ends at 9:05, you would subtract the start time from the end time. Starting at 7:10 and going up to 8:10 is one hour. From 8:10 to 9:05 is an additional 55 minutes. Therefore, adding these two parts together, the movie lasted for 1 hour plus 55 minutes, which is a total of 115 minutes.
Step-by-step, the calculation is as follows:
Calculate elapsed time from 7:10 to 8:10 (1 hour).Add the additional minutes from 8:10 to 9:05 (55 minutes).Combine both to find the total duration (1 hour + 55 minutes = 115 minutes).

Nick works two jobs to pay for college. He tutors for $15 per hour and also works as a bag boy for $8 per hour. Due to his class and study schedule, Nick is only able to work up to 20 hours per week but must earn at least $150 per week. If t represents the number of hours Nick tutors and b represents the number of hours he works as a bag boy, which system of inequalities represents this scenario?
A.) t + b greater than or equal to 20 15t + 8b = 150
B.) t + b less than or equal to 20 15t + 8b greater than or equal to 150
C.) t + b less than or equal to 20 15t + 8b less than or equal to 150
D.) None of the systems shown represent this scenario.
Answers
He can't work more than 20 hours so t+b must be less than or equal to 20.
He has to earn $150 so it cannot be less than 150. Theoretically he could earn more, e.g doing 10 hours of each job which equals $230
Therefore t + b less than or equal to 20 15t + 8b greater than or equal to 150
Answer:
Option B is the correct answer.
Step-by-step explanation:
Earning for tutoring per hour = 15$
Earning for bag boy per hour = 8$
We have Nick is only able to work up to 20 hours per week but must earn at least $150 per week and t represents the number of hours Nick tutors and b represents the number of hours he works as a bag boy.
Nick is only able to work up to 20 hours per week
t + b ≤ 20
But must earn at least $150 per week
15 t + 8 b ≥ 150
Option B is the correct answer.

Three friends each have some ribbon. Carol has 90 inches of ribbon, tino has 13.5 feet of ribbon, and baxter has 1.5 yards of ribbon. Express the total length of ribbon the three friends have in inches, feet, and yards.
Answers
To find the total length of ribbon Carol, Tino, and Baxter have, first convert each length into the same unit. The total length of ribbon is 306 inches, 25.5 feet, or 8.5 yards when combining all their ribbons.
The lengths of ribbon that Carol, Tino, and Baxter have must be expressed in the same unit to find the total length. We will convert all lengths into inches, feet, and yards.
Carol's ribbon: 90 inches
Tino's ribbon: 13.5 feet × 12 inches/foot = 162 inches
Baxter's ribbon: 1.5 yards × 3 feet/yard = 4.5 feet then 4.5 feet × 12 inches/foot = 54 inches
Total Length in Inches:
90 + 162 + 54 = 306 inches
Total Length in Feet:
306 inches ÷ 12 inches/foot = 25.5 feet
Total Length in Yards:
25.5 feet ÷ 3 feet/yard = 8.5 yards
Now we have the total length of ribbon in all three units: inches, feet, and yards.

If EF = 5w + 20, FG = 7w + 28, and EG = 72, find the value of w. Find EF and FG
Answers
Answer:
w = 2, EF = 30 , FG = 42
Explanation:
We have EF = 5w + 20 and FG = 7w + 28
Since these points E, F and G are col-linear points we have.
EG = EF + FG
And given that EG = 72
So, EF+EG = 72
5w + 20 + 7w + 28 = 72
12w + 48 = 72
12 w = 24
w = 2
So EF = 5w + 20 = 5x2 + 20 = 30
FG = 7w + 28 = 7x2 + 28 = 42
