the price of a climbing trip to mount kilimanjaro includes an initial fee plus a constant fee per meter. the table compares the total distance of a trip (in meters) and the price of the trip (in dollars).
Answer:
[tex]200\ m[/tex]
Step-by-step explanation:
Let
x------> total distance of a trip
y-------> the price of a trip
step 1
Find the slope
Let
[tex]A(70,114.1),B(100,118)[/tex]
[tex]m=\frac{(118-114.1)}{100-70}=0.13\frac{\$}{m}[/tex]
step 2
Find the equation of the line into point slope form
[tex]y-y1=m(x-x1)[/tex]
we have
[tex]m=0.13[/tex]
[tex]A(70,114.1)[/tex]
substitute
[tex]y-114.1=0.13(x-70)[/tex]
[tex]y=0.13x-9.1+114.1[/tex]
[tex]y=0.13x+105[/tex]
step 3
For [tex]y=\$131[/tex]
Find the value of x
substitute in the linear equation and solve for x
[tex]131=0.13x+105[/tex]
[tex]0.13x=131-105[/tex]
[tex]x=26/0.13=200\ m[/tex]

What is the domain of the function y= sqrt3/x ? plese help
Answer:
all reals, except at x=0
Step-by-step explanation:
because x is in the denominator, x cannot equal 0
For this case we have a function of the form [tex]y = f (x),[/tex]where:
[tex]f (x) = \sqrt {\frac {3} {x}}[/tex]
we must find the domain of the function.
The domain is given by all the values for which the function is defined.
Note that "x" is not defined for negative numbers or for zero. Then x can only take strict higher values to zero.
Domain: {x | x> 0}
Answer:
Domain: {x | x> 0}

Step-by-step explanation:
Which description can represent the surface area of this trunk
Answer:
It's B.
Step-by-step explanation:
A trunk has six faces . The total surface area will be the sum of the areas of these faces.
The surface area of a rectangular prism (like a trunk) is the total area of the surface of the object and can be found using the formula A = 2lw + 2lh + 2wh, where 'l' represents length, 'w' represents width and 'h' represents height.
Explanation:The surface area of a trunk, or any three-dimensional object, refers to the total area that the surface of the object occupies. In the case of a trunk, if we consider it as a rectangular prism (a box shape), that surface area can be found by adding the areas of all six faces of the prism. The formula to calculate the surface area (A) of a rectangular prism is A = 2lw + 2lh + 2wh where l denotes length, w width, and h height. Let's say, for example, that your trunk has a length of 3 units, a width of 4 units, and a height of 2 units. The surface area would then be 2*(3*4) + 2*(3*2) + 2*(4*2) = 24 + 12 + 16 = 52 square units.

what is the horizontal asymptote of the function f(x)= -2x/x+1
Answer:
-2
Step-by-step explanation:
We have been given a function f(x)=\frac{-2x}{x+1} and we are asked to find the horizontal asymptote of our given function.
Recalling the rules for a horizontal asymptote:
1. If the numerator and denominator have equal degree, the horizontal asymptote will be the ratio of the leading coefficients.
2. If the polynomial of denominator has larger degree than the numerator, then the horizontal asymptote will be the x-axis or y=0.
3. If the polynomial of numerator has larger degree than denominator, then the function has no horizontal asymptote.
Here, the numerator and denominator are of the same degree. So the horizontal asymptote will be the ratio of the coefficients.
Horizontal asymptote = [tex]-\frac{2}{1}[/tex] = -2
Which value is the solution to the equation? -3(t-7) = 24
Answer:
-3(t - 7) = 24
t - 7 = -8
t = -1
Final answer:
The correct solution to the equation -3(t-7) = 24 is t = -1, which contradicts the reference indicating solutions for a different quadratic equation.
Explanation:
The equation presented, -3(t-7) = 24, does not yield the solutions t = 3.96 and t = -1.03 as the provided reference indicates. Instead, those solutions seem to be related to a different quadratic equation. To solve the given linear equation for t, you need to perform the following steps:
Distribute the -3 across the parenthesis: -3t + 21 = 24.Subtract 21 from both sides of the equation: -3t = 3.Divide both sides of the equation by -3: t = -1.Therefore, the solution to the equation -3(t-7) = 24 is t = -1.

A petroleum laboratory technician is working at a petroleum storage depot in the oil-analysis laboratory. The lab tech is running tests on a sample from a 45-gallon oil-solvent mixture that contains 18 gallons of oil.
What is the ratio of the number of gallons of oil to the number of gallons of solvent?
The ratio of the number of gallons of oil to the number of gallons of solvent is 2:3.
Explanation:The ratio of the number of gallons of oil to the number of gallons of solvent can be determined by subtracting the number of gallons of oil from the total volume of the mixture and then dividing by the number of gallons of solvent. In this case, the total volume of the mixture is 45 gallons and the number of gallons of oil is 18. So, the number of gallons of solvent is 45 - 18 = 27. Therefore, the ratio of the number of gallons of oil to the number of gallons of solvent is 18:27, which can be simplified to 2:3.

Step-by-step explanation:
Hello, you need to divide that form into two forms: a triangle and a square.
For square:
A1 = 7in X 7in = 49 in2
For triangle:
A2 = [(7in) X (11in-7in)]/2 = 10.5 in2
So, the total area is the sum of A1+A2

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 2 large boxes and 5 small boxes has a total weight of 57 kilograms. A delivery of 8 large boxes and 3 small boxes has a total weight of 126 kilograms. How much does each type of box weigh?
Final answer:
The large box weighs 13.5 kilograms and the small box weighs 6 kilograms.
Explanation:
To solve this problem, we can assign variables to represent the weight of each type of box. Let's say the weight of a large box is L and the weight of a small box is S.
From the given information, we can set up a system of equations:
2L + 5S = 57 (Equation 1)
8L + 3S = 126 (Equation 2)
We can solve this system of equations using the method of substitution or elimination. Let's use elimination:
Multiply Equation 1 by 8 and Equation 2 by 2 to eliminate the S variable:
16L + 40S = 456 (Equation 3)
16L + 6S = 252 (Equation 4)
Subtract Equation 4 from Equation 3:
34S = 204
Solve for S: S = 6
Substitute the value of S into Equation 1:
2L + 5(6) = 57
2L + 30 = 57
2L = 27
Solve for L: L = 13.5
Therefore, the large box weighs 13.5 kilograms and the small box weighs 6 kilograms.

Helaine graphed the equation 12x – 4y = 3. What was the slope of Helaine’s line?\
Answer:
[tex]\large\boxed{\text{The slope}\ m=3}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
We have the equation of a line in the standard form:
[tex]12x-4y=3[/tex]
Convert to the slope-intercept form:
[tex]12x-4y=3[/tex] subtract 12x from both sides
[tex]-4y=-12x+3[/tex] divide both sides by (-4)
[tex]y=\dfrac{-12}{-4}x+\dfrac{3}{-4}\\\\y=3x-\dfrac{3}{4}[/tex]
Answer: The required slope of the given line is 3.
Step-by-step explanation: Given that Helaine graphed the following equation :
[tex]12x-4y=3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We are to find the slope of the line.
We know that
the slope-intercept form of a straight line is given by
[tex]y=mx+c,[/tex] where m is the slope of the line.
From equation (i), we have
[tex]12x-4y=3\\\\\Rightarrow 4y=12x-3\\\\\Rightarrow y=\dfrac{12x-3}{4}\\\\\\\Rightarrow y=3x-\dfrac{3}{4}.[/tex]
Comparing with the slope-intercept form, we get
slope, m = 3.
Thus, the required slope of the given line is 3.

Answer:
80.73 each month
Step-by-step explanation:
The original price of the computer is $598. It is offered for 25% off. This means you pay 75% of the original price or 0.75(598) = 448.5. The sales price is $448.50. You will pay 8% tax on this price. This means you'll pay 100% of the price plus 8% more. So this is 1.08(448.5) = 484.38.
In total you pay 484.38 over 6 months. This means each month you pay 484.38/6 = 80.73.

what percent is 18 out of 30?
Answer:
60%
Step-by-step explanation:
p/100 = 18/30
Multiply each side by 100
p/100 *100 = 18/30 *100
p = 60
18 is 60 percent of 30
The number 18 out of the number 30 is 60 percent.
We need to find what percent is 18 out of 30.
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Here, 18/30
= 9/15
= 3/5
= 0.6
In percentage 0.6×100
= 60%
Therefore, the number 18 out of the number 30 is 60 percent.
