The number of people that belong to a certain social website is 412 and growing at a rate of 5% every month. How many members will there be in 9 months? (round to the nearest whole number)
Any and all help is appreciated!
Answer: 639
Step-by-step explanation:
Given: The number of people that belong to a certain social website=412
Since they are increasing at the rate of 5% every month .
The number of members of after x months is given by exponential growth function, i.e. [tex]y=A(1+r)^x[/tex], where A is the initial amount , r is the growth rate
From question, A=412
r=5%=0.05
x=9 months
Therefore, [tex]y=412(1+0.05)^9=412(1.05)^9=412\times1.551=639.1356\approx639[/tex]
hence, there will be 639 members agter 9 months.

Brand X costs $2.40 for 16 ounces. Brand Y costs $1.92 for 12 ounces. Find the unit price of each brand. Which brand is the better buy? Please Help! Thanks
To find the unit price, divide the cost by the number of ounces for each brand. Brand X has a unit price of $0.15 per ounce, while Brand Y has a unit price of $0.16 per ounce. Brand X is the better buy because it has a lower unit price.
Explanation:To find the unit price of each brand, we need to divide the cost by the number of ounces for each brand.
Brand X: Unit Price = $2.40 / 16 ounces = $0.15 per ounce
Brand Y: Unit Price = $1.92 / 12 ounces = $0.16 per ounce
Therefore, Brand X is the better buy because it has a lower unit price.

sorry if this is incorrect your question was a little confusing
The Equations are 2x = 108 and 3y = 108.
Drain A takes 54 minutes and Drain B takes 36 minutes to empties the pool.
What is Unit rate?When comparing two different kinds of numbers with distinct units, a rate is a ratio that is employed. The unit rate, on the other hand, shows how many units of one quantity are equal to one unit of another.
Given:
Drain A empties a pool at a rate of 2 gal/min.
Drain B empties a pool at a rate of 5 gal/min.
One pool has 108 gal of water in it.
So, let Drain A empties the pool in x minutes and Drain B in y minutes.
Then, Drain A:
2x = 108
x= 54 minutes
and, Drain B:
3y = 108
y= 36 minutes

Sarah and her friends picked 3 3/4 pints of blueberries. After they ate some of the blueberries, only 2 1/3 pints remained.
How many pints of blueberries did Sarah and her friends eat?
Answer: 1 5/12
Step-by-step explanation:
2 1/3 = 7/4
3 3/4 = 15 / 4
The amount they eat = The amount they picked - The amount they remained
The amount they eat = 15 / 4 - 7/3
=45-28 / 12
=17/12

daphne was given a riddle to solve the sum of two consecutive positive integers is 71 find the two positive integers
Two consecutive positive integers that sum to 71, a simple equation can be used leading to the solution that the integers are 35 and 36.
Tasked with finding two consecutive positive integers whose sum is 71. To solve this, let's represent the smaller integer as n, which means the next consecutive integer is n+1. According to the riddle, the sum of these two integers is 71:
n + (n + 1) = 71
Solving this equation:
2n + 1 = 71
2n = 71 - 1
2n = 70
n = 35
The smaller integer is 35, and the next consecutive integer is 36. Therefore, the two consecutive positive integers are 35 and 36.

There are two buildings bisede each ather that are 47feet and 31 feet high. The buildings are 12 feet apart. What is the distance between the rooftop of the bluilfings
The distance between the rooftops of two buildings, one 47 feet high and the other 31 feet high with a 12 feet gap between them, is 20 feet, as calculated using the Pythagorean theorem.
To determine the distance between the rooftops of two buildings with different heights, we should envision a right-angled triangle where the buildings form the two vertical legs, and the distance between them forms the base.
The height difference of the buildings gives us one leg of the triangle (47 feet - 31 feet = 16 feet), and the distance between them gives us the other leg (12 feet).
Using the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides, we can calculate the length of the hypotenuse, which is the distance between the rooftops.
The formula is c = ( √{a² + b²} ), where a and b represent the legs of the triangle, and c represents the hypotenuse.
For our problem:
Leg a (height difference): 16 feet
Leg b (distance apart): 12 feet
Plug the values into the formula:
c = √{16² + 12²}
c = √{256 + 144}
c = √{400}
c = 20 feet
So, the distance between the rooftops of the buildings is 20 feet.
Jordan and Jake each work during the summer. Jordan earns $9 per hour at her job. Jordan also gets a $10 weekly allowance. Jordan displayed her earnings in a table.
Hours: 0 1 2 3 4 5 6 7 8
Earnings: 10 19 28 37 46 55 64 73 82
Jake earns $6.50 per hour at his job. Jake also gets a $15 weekly allowance. Jake displayed his earnings in a graph. How many hours will it take for Jordan and Jake to earn the same amount of money?
I am desperate!!!
To find out when Jordan and Jake will earn the same amount, we need to set their earnings equations equal to each other and solve for the number of hours worked. The resulting value will be the number of hours at which they both earn the same amount.
Explanation:To determine the number of hours it will take for Jordan and Jake to earn the same amount of money, we need to solve an equation that sets their earnings equal to each other.
For Jordan, her earnings (EJ) are calculated as $9 per hour plus a $10 allowance. So, we write this as an equation:
EJ = 9h + 10.
Similarly, for Jake, his earnings (EJk) are calculated as $6.50 per hour plus a $15 allowance. So, his earning equation is given by:
EJk = 6.5h + 15.
To find when they earn the same, we set the two equations equal to each other:
9h + 10 = 6.5h + 15
By simplifying the equation, it results in 'h', which represents the number of hours needed for Jordan and Jake to earn the same amount of money.

A mule deer can run one over four of a mile in 25 seconds. At this rate, which expression can be used to determine how fast a mule deer runs in miles per hour?
twenty-five seconds over one-fourth mile = 36 miles per hour
one-fourth mile over twenty-five seconds = 36 miles per hour
one-fourth mile over twenty-five seconds = 100 miles per hour
twenty-five seconds over one-fourth mile = 100 miles per hour
The correct expression to determine how fast a mule deer runs in miles per hour is one-fourth mile over twenty-five seconds = 36 miles per hour.
To find the speed of the mule deer in miles per hour, we need to convert the time from seconds to hours and then use the formula for speed, which is distance divided by time.
First, let's convert 25 seconds into hours. There are 3600 seconds in an hour, so:
25 seconds * (1 hour / 3600 seconds) = 25/3600 hours
Now, we know that the mule deer runs one-fourth of a mile in 25 seconds. To find the speed in miles per hour, we divide the distance by the time in hours:
Speed (mph) = Distance (miles) / Time (hours)
Using the conversion above, we have:
Speed (mph) = (1/4 mile) / (25/3600 hours)
To simplify this, we multiply the numerator and denominator by 4 to get rid of the fraction in the numerator:
Speed (mph) = (1 mile) / (25/900 hours)
Now, we multiply the denominator by 900 to get the time in hours:
Speed (mph) = (1 mile) / (25/900 * 900 hours)
Speed (mph) = (1 mile) / (25 hours)
Next, we need to find out how many 25-hour intervals there are in one hour. To do this, we divide 1 by 25:
Speed (mph) = 1 mile * (1/25 hours)
Speed (mph) = 1/25 miles per hour
Since there are 25 intervals of 1/25 hours in one hour, the mule deer can cover 25 intervals of 1/4 mile in one hour:
Speed (mph) = 25 * (1/4 mile) per hour
Speed (mph) = 25/4 miles per hour
Speed (mph) = 6.25 miles per hour
However, this result does not match any of the options given in the question. It seems there was a mistake in the calculation. Let's correct it:
Speed (mph) = (1/4 mile) / (25/3600 hours)
Speed (mph) = (1/4) / (25/3600)
Speed (mph) = (1 * 3600) / (4 * 25)
Speed (mph) = 3600 / 100
Speed (mph) = 36 mph
This is the correct calculation. Therefore, the expression that represents the speed of the mule deer in miles per hour is one-fourth mile over twenty-five seconds equals 36 miles per hour.
