In 2001, 36,500 people attended a public concert. The attendance at the annual event has decreased by 3% each year since. Which equation models the attendance, y, at the event x years after 2001?
A.
y = 36,500 – 0.03x
B.
y = 36,500(0.97)x
C.
y = 36,500(0.03)x
D.
y = 36,500(1.03)x
The answer is A. Y= 36,500(1.03) ^x

Janice has $2.30 made up of dimes, pennies and quarters. She has as many dimes as pennies and she has 17 coins in all. How many quarters does she have? (PLEASE HELP ME)
Answer:The equation would be 230 = 25y + 10x + 1x or 230 = 25y + 11x
You would then need to solve for x and y, which I forget how to do with 2 variables but since we're working with small numbers what I would do is continuously subtract 25 from 230 until the remainder is divisible by 11.
230 - 25*7 = 55 = 11*5
x = 5
Ok, adding the equation 2x+y = 17 you will now be able to solve for the two variables using a system of equations.
yes, you can come up with an equation. actually, you can come up several equations to generate a system of equations.
your first equation is correct.
(1) 25q + 10d + 1p = 230
now, you're told that the number of dimes equals the number of pennies. that just means, in symbols:
(2) d = p
finally, you're told that you have 17 coins in all, i.e.:
(3) q + d + p = 17
you now have three equations and three unknowns. use (2) to reduce (1) and (3).
(1′) 25q + 11d = 230
(3′) q + 2d = 17
now solve for the three variables.
Answer:
7 quarters
Step-by-step explanation:
We can use the guess method.
17 coins altogether, and as many dimes as pennies.
The number of quarters must be odd. When you subtract an odd number of quarters from 17, you get an even number which will divide by 2 evenly giving you the same number of pennies and dimes.
Start with a guess of 7 quarters.
17 - 7 = 10
7 quarters + 5 pennies + 5 dimes have a value of $2.30
Wow, I got it with the first guess.
Answer: 7 quarters

if Kayla ran 2/3 of a mile in 8 minutes. If Kayla runs at
that speed, how long will it take her to run one mile?
Answer:
12 minutes
Step-by-step explanation:
First figure out how long it took her to run 1/3 of the mile.
2/3 ÷ 2 = 1/3
8 ÷ 2 = 4
So she ran 1/3 in 4 minutes.
Multiply that answer by 3 to get your full mile.
1/3 * 3 = 1 mile
4 * 3 = 12 minutes
Answer:
12 minutes
Step-by-step explanation:
In my brain, I divide the run into three parts (because the fraction has a base of three). If I ran two parts of those three in eight minutes, then to find the amount of time it took to run one part (cause that's how much we need to add), I need to divide the time by two, and then add it to the 8 minutes. When the math is done, a third of a mile can be ran in 4 minutes, which means that an entire mile can be ran in 12 minutes.

The value of p in the linear equation is -2. Therefore, option B is the correct answer.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The given equation is 24p + 12 - 18p = 10+ 2p - 6.
(24p-18p)+12=(10-6)+2p
6p+12=4+2p
6p-2p=4-12
4p=-8
p=-2
Therefore, option B is the correct answer.

Kiran is about to start hiking on a trail that is 1.8 miles long. In his past hikes on the same trail, he had walked at a constant rate of 2.4 miles an hour, which is 0.04 mile a minute. Function (F) represents Kiran's remaining distance on the trail, in miles, t, minutes after he starts walking. Write an equation to represent this function. Use function notation.
Answer:
F(t) = 1.8 - 0.04t
Step-by-step explanation:
Given that :
Length of trail = 1.8m
Walking speed = 0.04 miles per minute
Distance left, t minutes after one statues walking :
Total distance covered after t minutes = speed * time = 0.04t
Distance left after t minutes :
Initial distance - distance covered
Hence,
F(t) = 1.8 - 0.04t
a car manufacturer determines that it's profit, P, in thousands of pesos, can be modeled by the function P(x)=0.001 25x4+x-2, where x represents the number of cars sold. What is the profit at x=150?
Answer:

Step-by-step explanation:
substitute x to 150
=0.00125(x)^4+x-3
=0.00125(150)^4+150-3
WE ARE USING PEDMAS HERE SO BE CARE-FULL parenthesis,exponent,multiplication,division,addition,subtraction

Shania’s workout playlist includes songs from four types of music. ● 32 country songs ● 48 rap songs ● 12 hip-hop songs ● 8 blues songs
Answer:
Hi there
Step-by-step explanation:
What exactly is the question being asked?
The song is 4 times as likely to be country than it is to be blues.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Total number of songs = 32 + 48 + 12 + 8 = 100
If she randomly plays a song from this list,
Probability that the song is country = 32/100 = 8/25
Probability that the song is rap = 48/100 = 12/25
Probability that the song is hip hop = 12/100 = 3/25
Probability that the song is blues = 8/100 = 2/25
Probability of country = 8/25 = 4 (2/25) = 4 times probability of blues.
Hence the correct option is B. The song is 3 times as likely to be country than it is to be blues.
