Therefore, the correct answer is 3,375 miles, or option (d) is the correct option.
To find out how far Paul will drive in 15 days, we need to determine his average distance per day and then multiply that number by 15. To find Paul's average distance per day, we can divide the total distance he drove in 3 days by the number of days:
675 miles / 3 days = 225 miles/day.
So Paul drives an average of 225 miles per day. If he continues to drive this same distance every day, he will drive 225 miles/day * 15 days = <<225*15=3375>>3,375 miles in 15 days.
Why does it have the name "average speed"?The total distance something has traveled is divided by the total amount of time it took to traverse that distance to arrive at its average speed. Speed is the current rate of movement of something. Average speed is the speed that a vehicle travels at on average over the course of a trip.
What does the term "average speed" mean?A moving object's average speed is calculated by dividing its total distance traveled by its entire travel time. Distance traveled divided by average speed Overall Time. Meter per second is the S.I. unit of speed. KPH, or kilometers per hour, is another unit of speed.

Ralph and Liza are both driving fro Los Angeles to Santa Fe. Ralph leaves at 7:00 and averages 60 mph (miles per hour) on the way. Liza leaves at 7:25 and averages 65 mph on the way. The situation is modeled by this system, where x is number of hours after Liza leaves and y is the distance each will travel:
y=60x+25
y=65x
How long after Liza leaves will she pass Ralph, and how far will they each have traveled?
A. Liza will not pass Ralph, because she will never catch up with him.
B. Liza will pass Ralph after 3 hours, and they each will have traveled 205 miles.
C. Liza will pass Ralph after 5 hours, and they each will have traveled 325 miles.
D. Liza will pass Ralph after 4 hours, and they each will have traveled 260 miles.
To find the time and distance at which Liza passes Ralph, we need to solve the system of equations.
Subtracting the first equation from the second, we get:
65x - 60x = y - 25
5x = y - 25
y = 5x + 25
Substituting this value of y into the first equation, we get:
60x + 25 = 5x + 25
55x = 0
x = 0
This means that Liza will pass Ralph 0 hours after she leaves, or at the same time as Ralph. At this time, they will have both traveled 0 miles.
Therefore, the answer is A: Liza will not pass Ralph, because she will never catch up with him.

Please try to solve with without sin, cos, or any square roots.
Also, please do ASAP
ill award Brainliest if solved correctly without sin, cos, or any square roots!
Answer:
To find the area of a triangle, we can use the formula:
Area = (base * height) / 2
To find the area of triangle ABC, we first need to find the base and the height.
Since angle B is 75 degrees, we can use the fact that the sum of the angles in a triangle is 180 degrees to find the measure of angle A: 180 - 75 - 90 = 15 degrees.
Then, we can use the fact that the measure of an angle in a triangle is proportional to the length of the side opposite that angle to find the length of side AC:
AC/AB = m∠A/m∠B
AC = (m∠A/m∠B) * AB
Substituting, we get:
AC = (15/75) * 12 = 3
Now that we know the base and the height of the triangle, we can use the formula to find the area:
Area = (3 * 12) / 2 = 18
Therefore, the area of triangle ABC is 18 square cm.
14. If AABC is similar to ADEF, what proportion would be used to solve for 2?
The proportionality used in the given diagram is 4/3=12/x if ΔABC and ΔDEF are similar. So, option 4 is correct.
What is meant by triangle?Triangles are polygons because they have three vertices and three edges. This is one of the basic shapes in geometry.
In Euclidean geometry, any three non-collinear points determine a distinct triangle and a distinct plane (i.e. a two-dimensional Euclidean space). To put it another way, every triangle has a plane that it is contained in, and there is only one plane that contains every triangle. If and only if all geometry is the Euclidean plane, all triangles are contained in a single plane; however, this is no longer true in higher-dimensional Euclidean spaces. The topic of this article, unless otherwise stated, is triangles in Euclidean geometry, specifically the Euclidean plane.
We have to assume that ΔABC and ΔDEF are similar.
If the triangles are similar,
Then the proportionality is:
AB/BC=DE/EF
4/3=12/x
Therefore, the proportionality used in the given diagram is 4/3=12/x.
So, option 4 is correct.

Please help me. I know it’s 4 months but I don’t know what the total amount paid is including interest. If anyone could add the steps that would be awesome!
Divide by 12 to go from the APR to the monthly interest rate
(9.5%)/12 = 0.7916667%
The decimal form is 0.007916667 approximately.
Multiply this with the starting balance $1367.90 and we get:
0.007916667*1367.90 = 10.8292 which rounds to 10.83
The interest payment for the 1st month is $10.83; which means the principal payment would be 400-10.83 = 389.17
This principal payment will then drop the balance from $1367.90 to 1367.90-389.17 = 978.73 dollars.
The value $978.73 is now the starting balance of the 2nd month. This process of...
(a) Compute the interest(b) Subtract the interest from the $400 monthly payment to get the principal (with the exception of the last month as shown below)(c) Subtract the principal from the starting balance to get the ending balance.is repeated until the balance is $0.
This is what the table would look like
[tex]\begin{array}{|c|c|c|c|c|c|} \cline{1-6}\text{Month} & \text{Starting} & \text{Interest} & \text{Principal} & \text{Payment} & \text{Ending }\\& \text{Balance} & & & & \text{Balance}\\\cline{1-6}1 & 1367.9 & 10.83 & 389.17 & 400 & 978.73\\\cline{1-6}2 & 978.73 & 7.75 & 392.25 & 400 & 586.48\\\cline{1-6}3 & 586.48 & 4.64 & 395.36 & 400 & 191.12\\\cline{1-6}4 & 191.12 & 1.51 & 191.12 & 192.63 & 0\\\cline{1-6}\end{array}[/tex]
Many credit card companies and banks offer free calculators on their website, or you can find similar free calculators online elsewhere, that will quickly calculate a table like shown above. It is called an amortization table or amortization schedule.
With the exception of the 4th month, each row has the principal and interest add to the $400 monthly payment. The last row will have a payment of 1.51+191.12 = 192.63 dollars.
The total amount paid back would be 400+400+400+192.63 = 1392.63 dollars. This is the sum of the values in the "payment" column.
-------------------------------------------------------------------------
Here's another way to determine the answer.
The monthly payment formula is
[tex]\displaystyle P = \frac{Li}{1 - (1+i)^{-n}}[/tex]
where,
P = monthly paymentL = loan amount, aka starting balancei = monthly interest rate in decimal formn = number of monthsIn this case,
P = 400L = 1367.90i = 0.007916667 approximately (calculated earlier)n = unknownLet's solve for the variable n. We'll need logarithms to isolate the exponent.
Part 1
[tex]\displaystyle P = \frac{Li}{1 - (1+i)^{-n}}\\\\\\\displaystyle 400 = \frac{1367.90*0.007916667}{1 - (1+0.007916667)^{-n}}\\\\\\\displaystyle 400 = \frac{10.8292087893}{1 - (1.007916667)^{-n}}\\\\\\\displaystyle 400(1 - (1.007916667)^{-n}) = 10.8292087893\\\\\\[/tex]
Part 2
[tex]\displaystyle 1 - (1.007916667)^{-n} = 10.8292087893/400\\\\\\\displaystyle 1 - (1.007916667)^{-n} = 0.0270730\\\\\\\displaystyle -(1.007916667)^{-n} = 0.0270730-1\\\\\\\displaystyle -(1.007916667)^{-n} = -0.9729270\\\\\\\displaystyle (1.007916667)^{-n} = 0.9729270\\\\\\[/tex]
Part 3
[tex]\displaystyle \log((1.007916667)^{-n}) = \log(0.9729270)\\\\\\\displaystyle -n*\log(1.007916667) = \log(0.9729270)\\\\\\\displaystyle n = -\log(0.9729270)/\log(1.007916667)\\\\\\\displaystyle n = 3.4805965\\\\\\[/tex]
Each decimal value is approximate.
That value of n then rounds up to the nearest integer n = 4
We do not round to n = 3 since that would be one month short, as shown in the table above.
You can use a graphing calculator to quickly solve that equation for the variable n. It can be used as a way to visually confirm the answer.

Your car holds at most 14.5 gallons of gas. on the way to the grocery store, you use 1.5 gallons of gas. write an inequality to show the amount of gas you have left in your tank.
Answer:
Step-by-step explanation:
If the car holds at most 14.5 gallons of gas and you use 1.5 gallons of gas on the way to the grocery store, the amount of gas you have left in your tank can be represented by the inequality:
[tex]14.5 - 1.5 < = x[/tex]
This inequality can be read as "14.5 minus 1.5 is less than or equal to the amount of gas you have left in your tank, x."
Solving for x, we get:

Give your answer in its simplest form.
B) Find the value of b when the perimeter is 42 cm.
In terms of b, the perimeter expression is 6 + 4b and the value of b is 9
How to find an expression for the perimeter of the rectangle,From the question, we have the following parameters that can be used in our computation:
Dimensions = 8cm and 2b - 5 cm
The above parameters mean that
Length = 8
Width = 2b - 5
The perimeter is calculated as
Perimeter = 2 * (Length + Width)
Substitute the known values in the above equation, so, we have the following representation
Perimeter = 2 * (8 + 2b - 5)
Evaluate the like terms
Perimeter = 2 * (3 + 2b)
Open the brackets
Perimeter = 6 + 4b
B) Find the value of b when the perimeter is 42 cm.Here, we have
Perimeter = 42
This means that
6 + 4b = 42

The point where the tangent to the given equation is horizontal is [tex](x, y) = (-2, -5)[/tex].
To find the tangent of a curve, we have to find the first derivative of the function. Hence, the tangent of the given curve is given by
⇒ [tex]f'(x) = \frac{d{f(x)}}{dx} = \frac{d{x^{2}}}{dx} + \frac{d(4x)}{dx} - \frac{d(1)}{dx}[/tex]
⇒ [tex]f'(x) = 2x + 4[/tex]
Now, as the tangent is horizontal, that means the slope of the tangent is 0, hence setting [tex]f'(x) = 0[/tex] , we get the equation
⇒ [tex]f'(x) = 2x + 4 = 0[/tex]
Solving the equation obtained for the variable x,
⇒ [tex]2x = -4\\[/tex]

Step-by-step explanation:
1.
it is always the same.
the usual equation of a line is
y = ax + b
"a" being the slope, "b" being the y-intercept (the y-value when x = 0).
we see that the y-value is +3 when x = 0. that is "b".
for the slope we pick 2 points (with integer coordinates, if possible).
I see e.g. (0, 3) and (3, 0)
x changes by +3 (from 0 to 3).
y changes by -3 (from 3 to 0).
the slope "a" is -3/+3 = -1
the equation is
y = -x + 3
2.
and again the same
we see that the y-value is -3 when x = 0. that is "b".
I see e.g. (0, -3) and (3, 0) as points.
x changes by +3 (from 0 to 3).
y changes by +3 (from -3 to 0).
the slope "a" is +3/+3 = 1.
the equation is

If you randomly pick the piece of clothing and the color, what is the probability that you'll end up with an orange hat?.
The probability of ending up with an orange hat is 1/12. It is because here are twelve possible outcomes.
What is Probability?Probability is a branch of mathematics in which the chances of experiments occurring are calculated. It is by means of a probability, for example, that we can know from the chance of getting heads or tails in the launch of a coin to the chance of error in research.
It is represented mathematically as;
Probability = Number of Expected outcomes / Total number of outcomes
From the question, we can have the following outcomes;
Clothing = 4
Colors = 3
Pr (pick a clothing) = 1/4
Pr (pick a color) = 1/3
Pr (picking an orange hat) = 1/4 x 1/3
Pr (picking an orange hat) = 1/12.

At a hockey game, a vender sold a combined total of 250 sodas and hot dogs. The number of sodas sold was 42 more than the number of hot dogs sold. Find the number of sodas sold and the number of hot dogs sold.
sodas sold:
hotdogs sold:
Answer:
let x as hotdog and x + 42 as soda
x + x + 42 = 250
2x + 42 = 250
2x + 42 - 42 = 250 - 42
2x = 208
x = 104
sodas sold: x + 42 = 104 + 42 = 146 sodas
hotdogs sold: x = 104 hotdogs

heart and star pls <3 brainliest will be appreciated <3(っ◔◡◔)っ -{ elyna s }-Answer:
104 hot dogs sold
146 sodas sold
Step-by-step explanation:
s=number of sodas. h=number of hotdogs
s+h=250
s=h+42 ==> there were 42 more sells for soda than compared to hot dog
h+42+h=250 ==> plugin h+42 for s
h+h+42=250 ==> simplify
2h+42=250 ==> solve for h
2h+42-42=250-42 ==> isolate h by subtracting 42 on both sides
2h = 208
h = 208/2
h = 104 hot dogs sold
s=104+42 ==> plug in 104 for h in s=h+42
s = 146 sodas sold
