The cost to rent 1 canoe from the rent made by the group of the girls and boys is $25.
What are word problems?Word problems are a mathematical interpretation by using variables, numbers, and arithmetic operations to solve real-life problems.
From the given information:
The group of girls: 2c + 3t = 80 --- (1)The group of boys: 1c + 7t = 95 ---- (2)Now, we can have a system of equations, and we can solve for the number of canoes and the inner tubes rented.
Using Elimination method:
2c + 3t = 80 --- × (1)
c + 7t = 95 --- × (2)
2c + 3t = 80
-2c + 14t = 190
0 + -11t = -110
-11t = -110
t = -110/-11
t = 10
From equation (1)
2c + 3t = 80
2c + 3(10) = 80
2c + 30 = 80
2c = 80 - 30
2c = 50
c = 50/2
c = 25
Therefore, we can conclude that the cost of the rent of 1 canoe is $25.

F(x) = 2x2 – 3x 7 for the input value 2.what is the value of the function when x = 2?
Find the point on the line 6x+y=9 that is closest to the point (-3,1).
Convert the line equation to 'y = mx + c' form. We calculate the orthogonal distance from the point to a generic point on the line using the formula 'd = |Ax1 + By1 + C| / sqrt(A^2 + B^2)'. Solve the line equation for 'y' using the computed 'd'. This yields the point closest to (-3,1) on the line.
Explanation:The subject of the question involves the algebra of straight lines, specifically finding points on lines. The given line in the question is '6x + y = 9'. We want to find the point along this line that is closest to a given point (-3,1).
First, rewrite the equation in slope-intercept form: y = -6x + 9. Now recall the formula for the shortest distance from a point to a line, d = |Ax1 + By1 + C| / sqrt(A^2 + B^2), where 'A', 'B' and 'C' are the coefficients in the equation of the line, and '(x1, y1)' is the point.
In this case, A = -6, B = 1, C = -9, and the point is (-3,1). If we plug these into the formula, we can solve for 'd'. Then we solve the given equation for 'y' using the resulting 'd' value and we get the point which is closest to (-3,1) on the line '6x + y = 9'.

Write an equation of the line that passes through (−5, −2)(−5, −2) and is parallel to y=23x+1y=23x+1.
The equation of a line parallel to y=23x+1 that passes through the point (-5, -2) is y = 23x + 113.
Explanation:The subject of this question is geometry, specifically, the formulation of a linear equation. You're asked to write an equation of a line that passes through point (-5,-2) and is parallel to the line defined by the equation y=23x+1.
Parallel lines have the same slope, so since the given line has a slope of 23, our line will also have a slope of 23. The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. Here, 'm' is already known as 23. So, our equation currently is y = 23x + b.
We can determine 'b' using the given point (-5,-2). Substituting these coordinates into our equation gives -2 = 23*(-5) + b. Solving for 'b' renders b = -2 - (23*-5) = 113.
Therefore, the equation of the line that passes through (-5, -2) and is parallel to y=23x+1 is y = 23x + 113.

You are on a 650-mile trip. your car used eight gallons of gas to travel the first 210 miles of the trip. how much more gas will you need to make it the rest of the way at the same rate?
The car will need approximately 8.76 more gallons of gas to complete the remaining 440 miles of the 650-mile trip, assuming it continues to get the same mileage rate of 26.25 miles per gallon.
Explanation:To calculate the additional amount of gas needed to complete the 650-mile trip, given that the car used eight gallons to travel the first 210 miles, we need to find the car's mileage rate and then determine how much more gas is required for the remaining distance.
Step-by-Step Explanation
Therefore, the car will need approximately 8.76 more gallons of gas to complete the rest of the trip at the same rate.
To calculate the additional gas needed for the remainder of a 650-mile trip after using 8 gallons for the first 210 miles, first determine the gas mileage and then calculate the gas required for the remaining 440 miles. The car will need approximately 16.76 more gallons of gas to complete the trip.
Explanation:To determine how much more gas you will need to complete your 650-mile trip, after having used 8 gallons for the first 210 miles, you need to calculate your car's gas mileage and then use that information to find the amount of gas needed for the remaining distance.
First, let's compute your car's mileage:
Gas mileage = Distance driven / Gallons of gas usedGas mileage = 210 miles / 8 gallonsGas mileage = 26.25 miles per gallon (mpg)Now, let's subtract the miles you have already traveled from the total trip length to find the remaining miles:
Remaining distance = Total distance - Distance already traveledRemaining distance = 650 miles - 210 milesRemaining distance = 440 milesFinally, we calculate the amount of gas needed for the remaining distance:
Gallons needed = Remaining distance / Gas mileageGallons needed = 440 miles / 26.25 mpgGallons needed = approximately 16.76 gallonsTherefore, you will need approximately 16.76 more gallons of gas to complete your trip, assuming the gas mileage remains consistent.

A spherical balloon is inflated with gas at a rate of 900 cubic centimeters per minute.
(a) How fast is the radius of the balloon changing at the instant the radius is 40 centimeters?
___cm/min
(b) How fast is the radius of the balloon changing at the instant the radius is 90 centimeters? _____ cm/min
...?
The rate at which the radius of the balloon is changing can be found by differentiating the volume formula for a sphere. Substituting the given values into the formula, we can calculate the rate of change at specific radii.
Explanation:To find the rate at which the radius of the balloon is changing, we can use the relationship between the volume and the radius of a sphere. The volume of a sphere is given by the formula V = (4/3)πr³, where V is the volume and r is the radius. Taking the derivative of both sides with respect to time, we get dV/dt = 4πr²(dr/dt). We are given that dV/dt = 900 cm³/min and we need to find dr/dt when r = 40 cm and r = 90 cm.
(a) Plug in the values into the formula: 900 = 4π(40)²(dr/dt). Solve for dr/dt: dr/dt = 900/(4π(40)²) ≈ 0.178 cm/min.
(b) Repeat the same steps for r = 90 cm: 900 = 4π(90)²(dr/dt). Solve for dr/dt: dr/dt = 900/(4π(90)²) ≈ 0.020 cm/min.

corresponding reference angle to 17pi/7
The corresponding reference angle to 17π/7 radians is π/7.
Explanation:The corresponding reference angle to 17π/7 radians is found by determining the smallest positive angle such that when added to 17π/7 radians, the resulting angle lies between 0 and 2π radians.
To find the reference angle, we can subtract 2π radians repeatedly until we obtain an angle between 0 and 2π radians.
In this case, we have:
17π/7 - 2π = π/7
Therefore, the corresponding reference angle to 17π/7 is π/7 radians.
