Logical Error: In computer programming language, a logic error is a bug or in a program or code that causes it to operate incorrectly, but not to terminate abnormally (or crash).

A logic error developed unintended or undesired output or other behavior, although it may not immediately be recognized as such.

For example, assigning a value to the wrong variable may cause a many of unexpected program errors.

These errors can be programmer mistakes or sometimes machine less memory to load the code.

if(x>=5) {

// program

}

else if(x==5) {

//program

}

else(x<=5) {

//program

}

they all do not give any error.

x=5 gave an error because it is value assigning to 5.

Step-by-step explanation:

Answer:

he would pay $73.40 for 8 games and 10 rides

Step-by-step explanation:

multiply 3.50 by 8 since it costs him 3.50 per each ride. when calculated u get 28.40.then when calculated multiply 4.50 by ten since that is how much each ride costs. the total should be 45.00. now add 28.40 to 45.00 to get ur answer

Answer:

Step-by-step explanation:

It looks much harder than it really is

Let the first number = 25

Let the second number = x

25 * x = 133600            divide both sides by 25

25*x/25 = 133600/25

x = 5344

Make sure the answer really is 133600 because the comma (one) should go before the 6.

The estimated product of 42,475 and 0.306 is 12,000.

To estimate the product of 42,475 and 0.306, we can round each factor to its greatest place.

42,475 rounds to 40,000 (rounded to the nearest thousand) since the digit in the thousands place is the greatest.

0.306 rounds to 0.3 (rounded to the nearest tenth) since the digit in the tenths place is the greatest.

Now we can multiply the rounded numbers:

40,000 × 0.3 = 12,000

Therefore, the estimated product of 42,475 and 0.306 is 12,000. This estimation provides a rough approximation of the actual product by simplifying the numbers and ignoring the decimal places beyond the tenths. However, it may not be as precise as the actual product obtained by performing the multiplication with the original, unrounded numbers.

Step-by-step explanation:

the ship is 472 m from the lighthouse

Step-by-step explanation:

from the question, we can know ∠OAS = 90°-23° =67° and AO = 200m

OS = A0 • tan 67°

= 200 m • 236°

= 472 m

Answer:

x = 42°

Step-by-step explanation:

You can mark the opposite angle from 96° as 96° and the 2 other unknowns as y.

96 • 2 + 2y = 360

168 = 2y

y = 84

x is half of y.

84 ÷ 2 = 42

Answer:

x<-4 or x≤4

Step-by-step explanation:

The solution of the inequality is x > -4 and x ≤ 4.

So, the graph B is correct.

Given is an inequality, x+7 > 3 and x-5 ≤ -1, we need to solve and identify the graph,

To solve the compound inequality, let's solve each inequality separately and then find the intersection of the solutions.

Inequality 1: x + 7 > 3

Subtract 7 from both sides:

x > 3 - 7

x > -4

Inequality 2: x - 5 ≤ -1

Add 5 to both sides:

x ≤ -1 + 5

x ≤ 4

Now, we need to find the intersection of the solutions for both inequalities.

Since the conjunction between the two inequalities is "and," we need to find the common solution.

The common solution is the values of x that satisfy both x > -4 and x ≤ 4. From the two inequalities, we can see that the common solution range is from -4 to 4, including -4 but not including 4.

Therefore, the solution to the compound inequality is: -4 < x ≤ 4

The total work required to fill all the shelves by multiplying the work done for each shelf by the total number of shelves: Total work = Work per shelf x Number of shelves= 61.6 J x 4 shelves= 246.4 J Therefore, it requires 246.4 joules of work to fill all the shelves.

The library shelf is made up of five shelves. The first shelf is 15 cm off the ground, and the other four shelves are spaced 38 cm apart. The average book has a height of 22 cm and a mass of 1.40 kg.
Each shelf can hold up to 28 books placed vertically, To solve this problem, we need to find the total amount of work required to move all books from the floor to the shelves. We can calculate the work done using the following formula:
Work = Force x Distance Since the books are initially lying flat on the floor, we need to lift them up to each shelf.
Therefore, the force required to lift the books is equal to the weight of all the books, which is given by:Force = mass x gravity where gravity is the acceleration due to gravity and is equal to 9.81 m/s^2.
The mass of each book is 1.40 kg, and the total number of books that can be stored on each shelf is 28 books.
Therefore, the mass of books on each shelf is given by:
mass of books on each shelf = 1.40 kg/book x 28 books= 39.2 kgNow, we can calculate the force required to lift the books on each shelf using:Force = mass x gravity= 39.2 kg x 9.81 m/s^2= 385 N
To find the work required to lift all the books onto each shelf, we need to multiply the force required by the distance lifted.
The distance lifted for each shelf is given by:Distance = shelf height - book height= 38 cm - 22 cm= 16 cm= 0.16 m

The cost of the Verizon plan for m messages is ...

  v(m) = 15 +0.10m

The two plans have equal costs when ...

  a(m) = v(m)

  25 + 0.05m = 15 + 0.10m

  10 = 0.05m . . . . . . . . . . . . . . subtract 15+0.05 m from both sides

Step-by-step explanation:

Right now, the average, or mean, is (23 + 35 + 27 + 48 + 18 + 35)/6 = 31

The number plus 23 + 35 + 27 + 48 + 18 + 35 and then divided by 7 should equal 35, that number is 45

(23 + 35 + 27 + 48 + 18 + 35 + 45)/7 = 33 = 231/7 = 33 = 33 = 33

Question:

Marshall models the data with the equation y = −1.5x + 121, where x represents the number of minutes spent watching television and y represents the number of minutes spent exercising.

A certain student watches television for an average of 38 minutes per night. Based on Marshall's model equation, how many minutes will that student spend exercising?

 Answer:

The student will exercise for 64 minutes

Step-by-step explanation:

Given

\(y = -1.5x + 121\)

x = minutes of TV

y = minutes on exercising

Required

Find y when x = 38

\(y = -1.5x + 121\)

Substitute 38 for x

\(y = -1.5 * 38 + 121\)

\(y = -57 + 121\)

\(y = 64\)

Answer:

h_max = 12.56 units

(the exercise does no specify the units)

Step-by-step explanation:

You have the following function:

\(h(t)=-16t^2+6t+12\)    (1)

To calculate the maximum height reach by you, you first derivative the function h(t) respect to t:

\(\frac{dh(t)}{dt}=-32t+6\)

Next, you equal the result of the derivative to zero and you obtain t:

\(-32t+6=0\\\\t=\frac{6}{32}=\frac{3}{16}\)

Then, you replace this value of t in the equation (1) and you obtain the maximum height:

\(h(t)=-16(\frac{3}{16})^2+6(\frac{3}{16})+12\)

\(h(t)=12.56\)

hence, the maximum height is 12.56 units

the answer is yes
