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.

what is percentage ?In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Occasionally, the acronyms "pct.," "pct," and "pc" are also used. But it is commonly indicated by the percent sign, "%." The % amount has no dimensions. Percentages are essentially fractions when the denominator is 100. Use the percent sign (%) to indicate that a number is a percentage by placing it next to it. For instance, you score a 75% if you properly answer 75 out of 100 questions on a test (75/100). Divide the money by the total and multiply the result by 100 to calculate percentages. The formula for calculating the percentage is (value/total) x 100%.

Answers
Using the division method it is obtained that Moses is left with 2 dog treats after feeding the 4 dogs with 3 dog treats each.
What is division?
One of the four fundamental mathematical operations—the others being addition, subtraction, and multiplication—is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things.
Number of dogs Moses volunteers with, x = 4
Number of dog treats Moses have, y = 14
Number of dog treats Moses gives to each dog = a
So, to find the value for a use the division method -
a = y/x
a = 14/4
a = 3(2/4)
Where, 3 is the quotient and 2 is the remainder.

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.

What is the role of the base and exponent in an exponential expression?
Answers
In an exponential expression, a base is a number that is raised to a certain power, represented by the exponent. The base can be any real number, while the exponent must be a positive integer.
Some key points to remember about the base and exponent in an exponential expression are:
The base represents the number being multiplied by itself a certain number of times.The exponent represents the number of times the base is multiplied by itself.The value of the exponential expression is the product of the base raised to the power of the exponent.The exponent can be positive or negative, and a base of 1 or 0 will always result in 1 or 0 respectively.The base can be any real number, but the exponent must be a positive integer.For example, in the expression "2^3" (read as "2 raised to the power of 3"), the base is 2 and the exponent is 3. This means that 2 is being multiplied by itself 3 times (222 = 8). So the expression evaluates to 8.

Tao rode his bike for 20 min at 12mph. How many miles did he go?
Answers
Tao rode his bike for 4 miles.
What are the speed, distance, and time?
Speed, distance, and time are related concepts in physics, and the relationship between them is often represented by the equation:
Speed = Distance/Time
To find out how many miles Tao rode his bike, you can use the formula:
distance = speed x time
In this case, the speed is 12 mph (miles per hour) and the time is 20 minutes. To convert the time to hours, you need to divide 20 minutes by 60 minutes (1 hour) which gives us 0.33 hours.
So,
distance = 12 mph x 0.33 hours = 4 miles
Hence, Tao rode his bike for 4 miles.

Answers
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
