Answer:
30 miles from your home
Step-by-step explanation:
You will meet at distance d from your home.
You will drive distance d at 30 mph until you meet them for t time.
Your uncle and aunt already traveled 5 miles before you start, so when you meet them, they will have traveled d - 5 miles from the moment you start. They travel d - 5 miles in the same time t you travel d miles.
speed = distance/time
time = distance/speed
Your uncle and aunt:
t = (d - 5)/25
You:
t = d/30
The t is the same for both, so we equate the right sides of the equations above.
(d - 5)/25 = d/30
Multiply both sides by the LCD of 25 and 30 which is 150.
150 * (d - 5)/25 = 150 * d/30
6d - 30 = 5d
d = 30
Answer: 30 miles from your home

Answer:
the variables are the time and/or distance "you" traveled.
Step-by-step explanation:
The problem gives two relations between speed, time, and distance. The speeds are given, so you could define variables for the time and distance of travel.
Since the question asks only for the distance until the parties meet, only one variable is necessary. That variable could represent either the time or the distance to the meeting point. (It more directly answers the question if it represents the distance, but it may make the equation more difficult to write.)
In every case, distance = speed × time.
_____
Here are three ways to set up the problem.
__
Using d for distance (miles), t for time (hours) since "you" started.
d = 5 + 25t . . . . . distance traveled by aunt and uncle
d = 30t . . . . . . . . distance traveled by you
__
Using t for time (hours) since "you" started.
5 +25t = 30t . . . . time until the distances traveled are the same
for this, the answer to the question is 5+25t or 30t, as you wish
__
Using d for distance (miles) until the parties meet
d = 5 +(d/30)(25) . . . . . aunt and uncle traveled (d/30) hours at 25 mph

How do you find a slope and the Y intercept
Answer:
Step-by-step explanation:
Typically in a line the y intercept is the point where your graph crosses the y-axis, and the x value is 0 so (0,b) is the y-intercept where y-intercept is b
The slope can be found by finding the rate of change, so the change in y / the change in x
You can also calculate the slope with 2 points so (x1, y1) (x2, y2)
you take the y values and subtract them, then divide by the x values like this:
y2 - y1 / x2 - x1
If a line is going up to the right in Quadrant I then the slope is positive, if the slope of the line goes down in Quadrant IV then the line slope is negative
Slopes of horizontal lines are zero, the slope of a vertical line is undefined
We use the letter m to stand for the slope

Doing that multiplication and rounding to the nearest tenth leaves us with a circumference of 168.6 inches.
At 7:00 am, the temperature was -4℉. At 9:00 am, it was 8° warmer. What was the temperature at 9:00 am? *
4℉.
What we know about Degrees is that there is a Positive type and a negative type.
(i.e: 30℉ is positive and -30℉ is negative.)
If the temperature was -4℉ at 7AM, then it is negative. If it goes up by an amount that is more than 4 then that negative will go up to a positive temperature. In this case: At 9AM it was 8° warmer.
Warmer is a keyword. If it is warmer by an amount, Negative temperatures will go up to a positive and positive temperature will just go up. If it gets cooler, negative temperatures will go down further and positive temperatures will go down to a negative.
So lets work out this problem with our newfound knowledge.
-4° F at 7AM
8° warmer at 9AM
-4 + 8 = 4.
The temperature was 4° at 9AM.

Answer:
a) c
b) 62
Step-by-step explanation:
He is correct because the Median weight is 56 grams.
Option C is the correct answer.
The range of weights of Felipe's tomatoes is 62.
The interquartile range of weights of Felipe's tomatoes is 44 grams.
What is a median?It is the middle value of the given set of numbers after arranging the given set of numbers in order.
We have,
From the box plot,
Median = 56 grams
Now,
The statement that Felipe describe is correct because the median weight of 56 grams.
The range of the weights of the tomatoes.
= Highest value - Lowest value
= 78 - 16
= 62
The interquartile range of weights of Felipe's tomatoes.
= Upper quartile - Lower quartile
= 72 - 28
= 44 grams
Thus,
Median weight = 56 grams.
Range = 62
Interquartile range = 44 grams.

Sophia invested $79,000 in an account paying an interest rate of 6.8% compounded
continuously. Assuming no deposits or withdrawals are made, how long would it
take, to the nearest year, for the value of the account to reach $152,800?
Answer:
10
Step-by-step explanation:
The value of the account will reach $152,800 in 10 years.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
Interest compounded continuously means there is no limit for the process of compound of interest. It is compounding infinite times.
The formula for calculating the final amount when the interest is compounded continuously is,
A = P e^(r t)
Here, A is the final amount, P is the initial or principal amount, r is the rate of interest and t is the number of years.
Given that,
A = $152,800
P = $79,000
r = 6.8% = 6.8/100 = 0.068
We have to calculate t.
152,800 = 79,000 e^(0.068 t)
152,800 / 79000 = e^(0.068 t)
1.934 = e^(0.068 t)
Taking logarithms on both sides,
㏑ 1.934 = ㏑ e^(0.068 t)
We have ㏑(a)ⁿ = n ㏑(a)
0.65968 = 0.068t ㏑ e
0.65968 = 0.068 t × 1
t = 9.7 ≈ 10 years
Hence the amount is compounded to $152,800 in 10 years.

(0.1x + 0.15y/ x+y= 12/100) * 100
(10x + 15y/x+y = 12)*(x+y)
10x+15y= 12x + 12y

Answer:
x = 2.5
y = 5
Step-by-step explanation:
2x + 3y = 20
2x + y = 10 then y = 10 - 2x
substitute for y:
2x + 3(10 - 2x) = 20
2x + 30 - 6x = 20
reduce:
-4x = -10
divide both sides by -4:
x = 2.5
y = 10 - 2(2.5) = 5
check:
2(2.5) + 3(5) = 20
20 = 20
and
2(2.5) + 5 = 10
10 = 10
What happens to the hare(rabbit) population (size) when the lynx population increases to a high number? AND explain why this happens. What happens to the size of the lynx population when the hare(rabbit) population increases to a high number? AND explain why this happens. PLEASE HELP ME
At first, there are more lynx than rabbits. This is shown by the fact the orange curve is above the blue curve. Because there are more predators than prey, some predators will unfortunately go without food and starve (this assumes that rabbits are the lynx only food source). This die-off explains why the orange curve goes down or decreases.
As the predators die off, the prey has time to flourish. The rabbit population grows or increases. Note the blue curve going uphill as the orange curve goes downhill. The blue curve hits a peak point and it then goes down. This is due to the lynx population rebounding. There's more food for the lynx and the lynx population will increase. The lynx then eat the rabbits to bring the hare population down.
In short, as one population increases, the other decreases, and vice versa. This back and forth cycles indefinitely. This keeps things in balance so one population doesn't overwhelm a location. Keep in mind that I'm only focused on these two populations and no other animal species. Also, I'm not considering any other factors such as habitat loss. So this is a very simplistic view of what's going on in nature. It's considered a predator-prey model to give biologists a rough sense of what's going on.
The chart shows that we do have a cyclic up and down pattern for each population. For the most part, the peak rabbit populations seem to coincide with the lynx population increasing. Also, when the rabbit population is at its lowest, the lynx population is on the decline. Furthermore, when the lynx population is at its peak, the hare population is on the decline. The lynx population being at its lowest seems to coincide with the hare population increasing.
The exceptions to this general rule seem to be at around 1885, 1895, and 1905. During these time frames, it appears that the two populations are in lockstep together. In other words, they seem rise and fall at the same time. What could explain this is something like habitat loss that I mentioned earlier. Habitat loss would explain why a population decreases. Also, people hunting either animal would explain the population decrease if the hunting is intense enough. If the population gets too low, then governments may step in to enact endangered species laws to protect the animals so that the population could rebound again.
