Inez is taking a bicycling trip across the United States. Her destination is 3,280 miles away. If Inez travels 80 miles per day, how far does she have left to travel after 25 days of bicycling?
Answer: The distance left after 25 days is 1280 miles
Step-by-step explanation:
To calculate the distance, we use the formula:
\(s=\dfrac{d}{t}\)
where,
s = speed of the bicycle = 80 miles/day
t = time taken = 25 days
d = distance travelled = ? miles
Putting values in above equation, we get:
\(\text{d}=(80 \ \text{miles}/\text{day} \times 25 \ \text{days})=2000 \ \text{miles}\)
Total distance to the destination = 3280 miles
Distance traveled in 25 days = 2000 miles
Distance left after 25 days = [3280 - 2000] = 1280 miles
Hence, the distance left after 25 days is 1280 miles

Las edades de cuatro hermanos forman una progresión aritmética, y su suma es 32 años. El mayor tiene 6 años más que el menor. Halla las edades de los cuatro hermanos.
Answer:
The ages of the four siblings are: 5, 7, 9 and 11 years old.
Step-by-step explanation:
The computation of the age of the four siblings is shown below:
Given that
n = 4
a1 =? a2 =? a3 =? a4 =?
a4 = a1 + 6 years
S4 = 32
Based on the above information
As we know that
Sn = (a1 + a4) × n ÷ 2
S4 = (a1 + a4) × 4 ÷ 2
32 = (a1 + a1 +6) × 2
16 = 2a1 + 6
2a1 = 10
a1 = 10 ÷ 2
= 5
So, a4 = a1 +6
= 5 +6
= 11
a4 = a1 + (4-1) × d
11 = 5 + 3 × d
d = 6 ÷ 3
= 2
So,
a2 = a1 + d
= 5 + 2
= 7
a3 = a2 + d
= 7 + 2
= 9
Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.

The gateway arch in st. Louis, mo is approximately 630 ft tall. How many u. S. Nickels would be in a stack of the same height? each nickel is 1. 95 mm thick.
The gateway arch in st. Louis, MO is approximately 630 ft tall, the same height of the Nickels would be in a stack is 98474.
Height of Gateway Arch in St. Louis, MO = 630ft tall
We are asked, how many nickels would be in a stack of the same
height when 1 nickel is 1.95 mm thick.
Convert height in ft to mm
1 ft = 304.8 mm
630ft = X
After Cross Multiply,
630ft × 304.8mm/1ft
= 192024 mm.
To find how many nickel would be in a stack of the same height
= Total thickness/ Thickness of 1 US dime
= 192024 mm/1.95mm
= 98473.8
≈98474 nickels
Therefore, the number of nickel that would be in a stack of the same height is 98474.

She must drain, clean, and refill two reef tanks. The first tank hold 175 gallons of water and drains at a rate of 25 gallons per hour. The second tank holds 200 gallons of water and drains at a rate of 30 gallons per hour.
( 1 ) -Equation for tank {1} -
y = 175 - 25x

A car with good tires on a dry road can decelerate at about 2.5 m/s
2
when braking. If the car is traveling at 60 km/h, what distance is needed to stop at the red light? Your Answer:
To calculate the distance needed to stop at the red light, we can use the kinematic equation:
v_f^2 = v_i^2 + 2aΔx
where:
v_f = final velocity (which is 0 m/s since the car needs to stop)
v_i = initial velocity (60 km/h converted to m/s)
a = acceleration (deceleration in this case, which is -2.5 m/s^2)
Δx = distance
Converting the initial velocity from km/h to m/s:
v_i = 60 km/h * (1000 m/1 km) * (1 h/3600 s) ≈ 16.67 m/s
Plugging the values into the equation and solving for Δx:
0^2 = (16.67 m/s)^2 + 2 * (-2.5 m/s^2) * Δx
Simplifying the equation:
0 = 277.89 m^2/s^2 - 5 m/s^2 * Δx
Rearranging the equation to solve for Δx:
5 m/s^2 * Δx = 277.89 m^2/s^2
Δx = 277.89 m^2/s^2 / 5 m/s^2
Δx ≈ 55.578 m
Therefore, the distance needed to stop at the red light is approximately 55.578 meters.

To write the equation of a line you need to identify the slope (m) and the y-intercept (b).
\(y=mx+b\)Slope:
Two perpendicular lines have opposite slopes, as you have the nexrt equation for a perpendicular line to k:
\(4y-x=2\)Write it as y=mx+b to identify the slope (solve y):
\(\begin{gathered} 4y=x+2 \\ y=\frac{1}{4}x+\frac{2}{4} \\ \\ y=\frac{1}{4}x+\frac{1}{2} \end{gathered}\)The slope of the line above is 1/4. Then, the slope of line k is the opposite of 1/4.
Slope of K: m= -1/4Y-intercept:
To find the y intercept use the given point (1,2) and the slope in the equation:
\(y=mx+b\)y= 2
x= 1
m= -1/4
Find b:

After reading several online reviews, it is evident that the sentiment value of individual words plays a significant role in shaping the overall review. Users express their opinions and experiences, often influenced by the emotions attached to specific words.
Online reviews are a common way for users to share their thoughts and experiences about products, services, or places. The sentiment value of individual words is crucial in conveying the overall opinion of the reviewer. Positive words like "excellent," "amazing," or "satisfied" indicate a positive sentiment and contribute to a favorable review. Conversely, negative words such as "terrible," "disappointing," or "poor" signify a negative sentiment and may lead to a negative review.
The sentiment value of words has the power to influence not only the reader's perception but also the overall rating of a product or service. Words with strong positive or negative connotations tend to have a more significant impact on the reader's interpretation of the review. Moreover, words with neutral sentiment, like "average" or "okay," may indicate a lukewarm response.
Understanding the sentiment value of individual words allows readers to gain insights into the reviewer's emotional experience and overall satisfaction level.

A small town has 35003500 inhabitants. At 8AM,2808AM,280 people have heard a rumor. By noon half the town has heard it. At what time will 9090% of the population have heard the rumor?(Do not round kk in your calculation. Round your final answer to one decimal place.)
It will take approximately 3.9 hours from noon for 90% of the population to hear the rumor, which means they will have heard it by approximately 3:00 PM.
By noon, half of the town's population, which is 3500/2 = 1750, has heard the rumor. This means that 1750 - 280 = 1470 people heard the rumor between 8AM and noon. Therefore, the number of people who have yet to hear the rumor is 3500 - 1750 = 1750.
To find out when 90% of the population will have heard the rumor, we can use the formula:
(people who have heard the rumor) / (total population) = 0.9
Solving for the number of people who need to hear the rumor, we get:
(0.9)(3500) = 3150
To find out how many people need to hear the rumor from noon onwards, we subtract the number of people who have already heard it:
3150 - 1750 = 1400
To find out how long it will take for 1400 more people to hear the rumor, we can use the ratio:
(number of people who hear the rumor per hour) / (total population) = (1400 / 1750)
Solving for the number of people who hear the rumor per hour, we get:
(number of people who hear the rumor per hour) = (1400 / 1750) * (1 / k)
where k is the number of hours it takes for 90% of the population to hear the rumor. Solving for k, we get:
k = (1400 / 1750) * (1 / (number of people who hear the rumor per hour))
Plugging in the value of 280 for the number of people who heard the rumor from 8AM to noon, we get:
\(k = (1400 / 1750) * (1 / ((1470 + 280) / 4))\)
k = 3.86
Therefore, it will take approximately 3.9 hours from noon for 90% of the population to hear the rumor, which means they will have heard it by approximately 3:00 PM.

Find parametric equations of the curve of intersection of the following two surfaces:
(a) cylinder x2+y2=1 and the plane y+z=2
(b) parabolic cylinder x2=2y and the surface 3z=xy
The curve of intersection between the cylinder x^2 + y^2 = 1 and the plane y + z = 2 is a circle lying on the plane y + z = 2. The parametric equations for this curve are x = cos(θ), y = sin(θ), and z = 2 - sin(θ), where θ is the parameter representing points on the circle.
To find the parametric equations for the curve of intersection between the cylinder and the plane, we can start by parameterizing the cylinder using the angle θ. Since the equation x^2 + y^2 = 1 represents a circle in the x-y plane with radius 1, we can use θ as a parameter to represent points on this circle.
The parametric equations for the cylinder are:
x = cos(θ)
y = sin(θ)
z = 2 - y
Next, we substitute these equations into the plane equation y + z = 2 to determine the intersection points. By substituting y and z, we have sin(θ) + 2 - sin(θ) = 2, which simplifies to sin(θ) - sin(θ) = 0. This implies that the plane equation is satisfied for any value of θ.
Therefore, the intersection between the cylinder and the plane is the entire cylinder itself, lying on the plane y + z = 2. The parametric equations for the curve of intersection are x = cos(θ), y = sin(θ), and z = 2 - sin(θ).
