After solving the equation, the time in minutes Bob rides the scooter will be equal to 97 minutes.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given information in the question,

Total price paid to start the scooter = $3

Price of ride per minute = 11 cents

1 dollar  = 100 cents

So, 11 cents = 11/100 = $0.11 per minute

Then, the equation will be,

$3 + $0.11(x) = $13.67

Here, x is the total number of minutes.

0.11x = 13.67 - 3

Answer: w = 4

Step-by-step explanation:

To solve the equation 10(w+3) = 70, we will work to get w by itself:

1. Divide by 10. This will get us closer to w.

(10( w + 3))/10 = 70/10

w + 3 = 7

2. We now have the equation w + 3 = 7. All we need to do now to get w by itself (or isolate it) is to subtract 3.

(w + 3) - 3 = 7 - 3

w = 7 - 3

w = 4

3. We can check our solution by inputting our found value, w = 4, into the equation.

10( 4 + 3 ) = 70

10(7) = 70

70=70

Because both sides of the equation are true, our solution of w = 4 is correct.

Answer: w = 4

Step-by-step explanation:

10(w+3)=70

10w + 30 = 70

10w = 40

w = 4

Answer:

3 (for the box), p=1

Step-by-step explanation:

Since they want you to follow the instructions, divide by 2 to get (5p-2p) alone.

6p/2 = 3p (exactly like 6/2)

You will get 3p=5-2p

To solve the rest of the equation, add 2p to both sides (once you add 2p to the left side, it gets rid of it on the right side by canceling it out)

3p=5-2p

+2p  +2p

5p=5

Divide 5p by 5 to get p by itself.

5p/5 = 5/5

That is p = 1

Step-by-step explanation:

You want the difference between the largest and smallest 5-digit numbers whose digits are from the set {1, 2, 3} and include each of these at least once. The numbers cannot be divisible by 2 or 3.

The number will be divisible by 3 when its sum of digits is a multiple of 3. Since 1, 2, and 3 are prescribed digits, the remaining two digits must not have a total of 3 or 6. The largest possible remaining digits are {2, 3}, and the smallest remaining digits are {1, 1}. (Using {3, 3} for the largest digits would give a number divisible by 3.)

The number will be divisible by 2 if the least significant digit is 2. The largest and smallest digits are not 2, so that will not be an issue.

The largest number will place the largest available digit in the place with the highest place value: 33221.

The smallest number will place the smallest available digit in the place with the highest place value: 11123.

The desired difference is the difference of these numbers:

  33221 -11123 = 22098 . . . . difference of largest and smallest

The difference between the two numbers will be 1998.

A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.

The factor form of 3x² 10x 3 is 3x(x+3)(x-3). This is because 3x² 10x 3 can be factored into three linear terms: 3x(x+3)(x-3).

Factor is a quantity or an expression that is multiplied to another quantity or expression to obtain a product. Factors are used in mathematics to solve problems involving multiplication, division, and equations. Factors can also be used in financial analysis to calculate interest payments, loan repayments, and other financial transactions. Factors can also be used to analyze supply and demand, market trends, and other economic indicators.
This is achieved by using the 'FOIL' method, which stands for First, Outer, Inner, Last. The first two terms, 3x and x+3, are multiplied together to give 3x². The outer two terms, 3x and x-3, are multiplied together to give 3x-9. The inner two terms, x+3 and x-3, are multiplied together to give x²-3. The last two terms, 3x² and x²-3, are added together to give 3x² + x²-3 = 3x² + 10x - 3.

A function can have an asymptote if it approaches a horizontal or vertical line but never touches it. There are several types of functions that can have asymptotes, including rational functions, exponential functions, and logarithmic functions.

A continuous function in mathematics is a function without discontinuities, or any sudden changes in value. If we can guarantee arbitrarily small changes in the input of a function by limiting small enough changes, then the function is continuous.

There is no function that is always discontinuous. A function is either continuous or discontinuous at a particular point, but it is not necessarily either one at all points.

For example, the function f(x) = x^2 is continuous at all points, but the function g(x) = |x| is discontinuous at x=0.

On the other hand, there are functions that are discontinuous at an infinite number of points, such as the Dirichlet function, which is defined as follows:

f(x) = { 1 if x is irrational

{ 0 if x is rational

This function is discontinuous at all rational points, but it is continuous at all irrational points

Answer:

Step-by-step explanation:

If you're wondering about what percent of 212 is 400, the answer is 189.3%. This means that 400 is 89.3% higher than 212. It’s easy to see that, when compared side by side, 400 is a much bigger number, almost twice as great as 212. Put another way, if you divide 400 by 212, you get 1.89—that’s your answer! Clearly, 400 is a great deal larger than 212 and this difference in size can be expressed as a percentage increase of 189.3%.

Approximately 19.05% of 212 is 400.

Answer:

Step-by-step explanation:

Solution for 212 is what percent of 400:

212:400*100 =

(212*100):400 =

21200:400 = 53

Now we have: 212 is what percent of 400 = 53

Question: 212 is what percent of 400?

Percentage solution with steps:

Step 1: We make the assumption that 400 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=400$.

Step 4: In the same vein, $x\%=212$.

Step 5: This gives us a pair of simple equations:

$100\%=400(1)$.

$x\%=212(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{400}{212}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{212}{400}$

$\Rightarrow x=53\%$

Therefore, $212$ is $53\%$ of $400$.  

the answer is 53 or 188.68%

Information can not be determined by histogram.

What is histogram?

A histogram is an approximation of the distribution of numerical data. This term was first introduced by Karl Pearson. The first step in creating a histogram is to "bin" (or "bucket") the range of values. That is, divide the entire range of values ​​into a series of intervals and count the number of values. At each interval fall. Bins are usually specified as consecutive, non-overlapping intervals of a variable. The bins (intervals) must be contiguous and often (but not necessarily) the same size.

If the bins are the same size, bars are drawn across the bins, with heights proportional to frequencies (number of cases in each bin). Histograms can also be normalized to display "relative" counts, which indicate the proportion of cases falling into each of multiple categories with sum of heights equal to 1.
