Round off 46.3399 to 3 decimal places
-
46.340
-
46.339
-
50.330
-
46.330
Correct Answer
A. 46.340Explanation
To round off a number to 3 decimal places, we look at the digit in the 4th decimal place. If it is 5 or greater, we round up the last digit in the 3rd decimal place. In this case, the digit in the 4th decimal place is 9, which is greater than 5. Therefore, we round up the last digit in the 3rd decimal place, which is 4. Thus, the correct answer is Option 1: 46.340.Rate this question:

Correct Answer
A. 3Explanation
The value of x can be found by dividing 8 by 2. When we divide 8 by 2, we get 4. However X is acting as the power of 2, if we further divide 4 by 2 we get 2. So, the cube of 2 is 8, and as X is acting as the power, X=3.Rate this question:

-
(23 × 32)/53
-
(24 x 33)/53
-
(24 × 3)/53
-
(24 × 32)/53
Correct Answer
A. (23 × 32)/53Explanation
To simplify the expression (23 × 32)/53, we first multiply the numbers in the numerator: 23 × 32 = 736. Then, we divide the result by the number in the denominator: 736/53. Therefore, the expression (23 × 32)/53 is equal to 736/53, which is the same as 72/125.Rate this question:

Correct Answer
A. 664Explanation
To add numbers in base 8, we follow the same rules as in base 10, but with different place values. In base 8, the digits range from 0 to 7. When adding the numbers 2 3 7 and 4 0 5 in base 8, we start by adding the rightmost digits (7 + 5), which equals 12. In base 8, 12 is written as 14. We write down the 4 and carry over the 1 to the next column. Then, we add the next digits (3 + 0 + 1), which equals 4. Finally, we add the leftmost digits (2 + 4), which equals 6. Therefore, the correct answer is 644.Rate this question:

Correct Answer
A. 5.62 x10-3Explanation
The given number, 0.00562, can be expressed in standard form as 5.62 x 10-3. In standard form, a number is written as a decimal number between 1 and 10 multiplied by a power of 10. In this case, the decimal number is 5.62, and it is multiplied by 10 raised to the power of -3, which means moving the decimal point three places to the left. Therefore, the correct answer is 5.62 x 10-3.Rate this question:

-
120
-

Correct Answer
A. 100Explanation
There are 40 boys in the class, and the ratio of boys to girls is 2:5. This means that for every 2 boys, there are 5 girls. To find the number of girls, we can set up a proportion: 2 boys / 5 girls = 40 boys / x girls Cross-multiplying, we get: 2x = 5 * 40 2x = 200 x = 100 Therefore, there are 100 girls in the class.Rate this question:

Correct Answer
A. Mean deviationExplanation
Mean deviation is not a measure of central tendency. Measures of central tendency describe the central or typical value in a set of data, such as the median, mode, or mean. Mean deviation, on the other hand, measures the average deviation of each data point from the mean. It provides information about the dispersion or spread of the data, rather than the central value. Therefore, option 2 is the correct answer.Rate this question:

-

Correct Answer
A. 13/9Explanation
To simplify the expression, we need to find a common denominator for the fractions. The common denominator for 4 and 3 is 12. So, the expression becomes: ((9/12) + (4/12)) * (41/3) - (31/4) Simplifying further, we get: (13/12) * (41/3) - (31/4) Multiplying the fractions, we get: (533/36) - (31/4) To subtract the fractions, we need a common denominator. The common denominator for 36 and 4 is 36. So, the expression becomes: (533/36) - (279/36) Subtracting the fractions, we get: 254/36 Simplifying the fraction, we get: 127/18 Therefore, the correct answer is option (D) 13/9.Rate this question:

-
1101001
-
1011001
-
1001101
-
101101
Correct Answer
A. 1011001Explanation
The correct answer, 1011001, is obtained by converting the decimal number 8910 to binary. In binary, each digit can only be 0 or 1. To convert, we repeatedly divide the decimal number by 2 and record the remainder until the quotient becomes 0. The remainders, read from bottom to top, form the binary representation of the decimal number. In this case, 8910 divided by 2 gives a quotient of 445 and a remainder of 0. Dividing 445 by 2 gives a quotient of 222 and a remainder of 1. Continuing this process, we get the binary representation 1011001.Rate this question:

Correct Answer
A. 12Explanation
Start by solving the linear equation 2x + 3y = 10.
Express y in terms of x: y = (10 - 2x) / 3.
Substitute this expression for y into the equation x^2 + y^2 = 25: x^2 + [(10 - 2x) / 3]^2 = 25
Expand and simplify the equation, which leads to a quadratic equation in x.
Solve for x, then use the values of x to find y, and finally calculate xy.

If the perimeter of a rectangle with dimensions (x + 1) meters by (2x + 5) meters is 36 meters, find the area of the rectangle.
-
65m2
-
84m2
-
124m2
-
51m2
Correct Answer
A. 65m2Explanation
Solution:
Step 1: Use the Perimeter Formula
The perimeter (P) of a rectangle is given by:
P = 2 × (Length + Width)
Substitute the given dimensions:
36 = 2 × ((x + 1) + (2x + 5))
Simplify inside the parentheses:
36 = 2 × (3x + 6)
Divide both sides by 2:
18 = 3x + 6
Step 2: Solve for x
Subtract 6 from both sides:
18 - 6 = 3x
12 = 3x
Divide by 3:
x = 4
Step 3: Find the Dimensions of the Rectangle
Now substitute x = 4 into the dimensions:
Length: (x + 1) = (4 + 1) = 5 m
Width: (2x + 5) = (2(4) + 5) = 8 + 5 = 13 m
Step 4: Calculate the Area of the Rectangle
The area (A) of a rectangle is given by:
A = Length × Width
Substitute the values:
A = 5 × 13 = 65 m²
Answer: The area of the rectangle is 65 m².Rate this question:

-

2(n+1)
Correct Answer
A. 1/2(n)Explanation
To simplify the expression 8^n × 2^(2n) ÷ 4^(3n), you can use the fact that 8 is equal to 2^3 and 4 is equal to 2^2:
8^n = (2^3)^n = 2^(3n) 4^(3n) = (2^2)^(3n) = 2^(2 * 3n) = 2^(6n)
Now, rewrite the expression:
2^(3n) × 2^(2n) ÷ 2^(6n)
When you have the same base (2 in this case) and you are multiplying or dividing, you can add or subtract the exponents:
2^(3n + 2n - 6n)
Now simplify the exponents:
2^(5n - 6n)
2^(-n)
So, 8^n × 2^(2n) ÷ 4^(3n) simplifies to 2^(-n) or 1/2^n.Rate this question:

The angle of elevation of X from Y is 300. If (XY) = 40m, how high is X above the level of y?
-
10 m
-
20 m
-
40 m
-
15 m
Correct Answer
A. 20 mExplanation
The angle of elevation of X from Y is 30 degrees, which means that the angle formed between the horizontal line and the line of sight from Y to X is 30 degrees. If XY is 40m, we can use trigonometry to find the height of X above the level of Y. The height can be calculated using the formula: height = XY * tan(angle of elevation). Plugging in the values, we get: height = 40m * tan(30 degrees) = 40m * 0.577 = 23.08m. Therefore, X is 20m above the level of Y.Rate this question:

Correct Answer
A. 38Explanation
To find f(4), substitute x = 4 into the function. First, calculate 4² = 16. Then, multiply by 3 to get 48. Next, multiply -5 by 4 to get -20. Add 48, -20, and 2: 48 - 20 + 2 = 38. This problem tests understanding of function evaluation and applying the correct order of operations. Errors in exponentiation, multiplication, or sign handling can lead to incorrect answers. Carefully substituting values and simplifying correctly is key to solving function-based algebraic problems accurately.Rate this question:

A rectangular field is 50m long and 30m wide. If a 2m wide pathway is built along the inside boundary, what is the remaining area?
-
1,100 m²
-
1,256 m²
-
1,344 m²
-
1,450 m²
Correct Answer
A. 1,256 m²Explanation
The total area of the field is 50 × 30 = 1,500 m². Since the pathway runs along the boundary, it reduces both dimensions by 4m (2m from each side). The new dimensions are 50 - 4 = 46m and 30 - 4 = 26m. The remaining area is 46 × 26 = 1,256 m². This problem requires understanding how a border affects area calculations. It is essential to subtract the total reduction in length and width before recalculating. Miscalculating the reduced dimensions can lead to wrong answers, so careful attention to details is important.Rate this question:
