Answer: 185 minutes
c is the correct option
Step-by-step explanation:
let x = number of minutes
0.46x = 85.10
x = 85.10/0.46 = 185 minutes
Answer:
185 minutes
Step-by-step explanation:
See the attached worksheet. Note that there are no inequalites mentued in the problem. That eliminates options 1 and 4. Option 2 is set up correctly, except that the units are incorrect. The unit for 0.46 is $/min, not just $. The final unit should be minutes, not $.
Option 3 has the correct equation, and units. Note how the word problem can be translated to an equation. Start with setting up an equation, before mentally trying to answer the question. An guess at the answer might be helpful, but work with the equation to insure the details are included. A correct equation will allow proper unit cancellation, which will help verify that the answer is correct. In this case we wanted an answer with just minutes. Dividing $ by $/min reduces to only minutes ($/$/min = min).
========
Making an estimate first is a good safeguard against mistakes. We can mentally round up $0.46 to 50 cents/minute. If the total bill is almost $90, we'd expect an answer around 180 minutes ((90/0.5). We got 185, so we can feel comfortable that the problem was done correctly and quickly move on.

For the function 4^x=(1/8)^(x+5), the value of x, using exponents' properties is obtained as option 2: x = -3.
What is an exponent?
The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.
The given function is - 4^x=(1/8)^(x+5)
This function can be solved using the properties of exponents.
The first property of exponents is - (a^m)^n = a^(m·n)
The second property of exponents is - 1/(a^n) = a^-n
Simplify the left hand side of the function -
4^x = (2²)^x
Using the first property of exponents -
(2²)^x = 2^(2x)
Simplify the right hand side of the function -
(1/8)^(x+5) = (1/2^3)^(x+5)
Using the second property of exponents -
(1/2^3)^(x+5) = (2^-3)^(x+5)
Using the first property of exponents -
(2^-3)^(x+5) = 2^(-3x - 15)
The function then becomes -
2^(2x) = 2^(-3x - 15)
Since, the base is same they cancel out.
2x = -3x - 15
2x + 3x = -15
5x = -15
x = -3
Therefore, the value of x is obtained as x = -3.

Eliminate the parameter in the equations y = t + 2 and x = t superscript one-half. How can the rectangular equation be described?.
The equation can be described as a quadratic equation.
What is a quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x or any algebraic equation of highest degree. The standard form of the quadratic equation in variable is ax^2 + bx + c = 0 with a ≠ 0, where a and b are coefficients and constant. Since a quadratic equation is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
In this case, we have given that:
y = t + 2
So, y – 2 = t
Now, substitute the value of t in the equation:
x = t^1/2
x = (y – 2) ^1/2
And, by squaring both sides we will get:
x^2 = y – 2
y = x^2 + 2

What is the solution to this system of equations 2x y 40 x − 2y − 20?
The system of equations 2x + y = 40 and x - 2y = -20 has a solution of x = 12 and y = 16. We can solve this system by using the method of substitution or elimination.
One way to solve the system is to use the method of substitution. We can first solve one of the equations for one of the variables and substitute that expression into the other equation.
For example, we can solve the first equation for y by isolating y on one side: y = 40 - 2x. Then we can substitute that expression into the second equation and solve for x:
x - 2(40 - 2x) = -20
x - 80 + 4x = -20
5x = 60
x = 12
Then we can substitute x = 12 into the first equation, or either equation to find the value of y:
2(12) + y = 40
y = 16
So the solution to the system of equations is x = 12 and y = 16.
Another way to solve the system of equations is to use the method of elimination. This involves adding or subtracting the equations to eliminate one of the variables. For example, we can add the equations and get:
3x - y = 20
Then we can solve for x or y and substitute it back into either of the equation to find the other variable.

Hikers are traveling at 3.5 miles per hour. They leave camp and hike N72°W for 2 hours. They change course to S23°W for 4 hours. How many miles is the trip directly back to camp? What bearing should the hikers take to head back to camp?
Answer: To solve this problem, we can use the law of cosines. The law of cosines is a useful tool for solving problems involving distances and angles between points in two-dimensional space. We can use the law of cosines to find the distance between the starting and ending point of the hike, and the bearing to get back to camp.
The law of cosines states that:
c^2 = a^2 + b^2 - 2ab * cos C
where c is the distance between the two points, a and b are the distances of the two legs of the hike, and C is the angle between them.
Using the given information, we can set a as the distance traveled at 3.5 miles per hour for 2 hours, which is 3.5 * 2 = 7 miles,
b as the distance traveled at 3.5 miles per hour for 4 hours which is 3.5 * 4 = 14 miles,
C as the angle between the two legs of the hike which is (72 + 23) = 95 degrees.
Now we can substitute this values into the law of cosines formula:
c^2 = 7^2 + 14^2 - 2(7)(14) * cos 95
Solving this equation will give us the square of the distance between the starting and ending point of the hike. To find the actual distance, we'll have to take the square root of that.
The distance directly back to camp is √(196 - 98*(√2/2)) = √(196 - 98*(√2/2)) ≈ 8.14 miles
To find the bearing to head back to camp, we must know that the bearing of a line is defined as the angle between the line and the North direction, measured clockwise.
We can use the bearing of N72°W and S23°W to find the back bearing to camp.
The back bearing is (180 + 72 + 23) = 275 degrees. The hikers should take a bearing of 275 degrees to head back to camp.
