A decimal which can be written in fraction of the form of p/q is called.
A. Irrational number
B. Rational number
C. Terminating decimal
D. Non terminating decimal
Explanation: A rational number is a number that can be expressed as a fraction p/q, where p and q are integers and q is not equal to zero. Rational numbers can be written as either terminating decimals (decimals that have a finite number of digits after the decimal point) or repeating decimals (decimals that have a recurring pattern of digits after the decimal point). In both cases, they can be expressed as fractions.
30 ÷ 5 = 6, then the quotient is……..
A. 6
B. 5
C. 30
D. 0
HCF of
14, 35 and 98 is……..
A. 5
B. 7
C. 14
D. 35
Explanation: To find the Highest Common Factor (HCF) of 14, 35, and 98, we need to determine the largest number that divides evenly into all three given numbers.
Let's factorize each number:
14 = 2 × 7
35 = 5 × 7
98 = 2 × 72
From the factorizations, we can observe that the common factor among all three numbers is 7. Therefore, the HCF of 14, 35, and 98 is 7.
Hence, the correct answer is B. 7.
Find the value of x in the expression
2x – 7 = -8
A. 0
B. 15/2
C. 1/2
D. -1/2
Explanation: To find the value of x in the expression 2x - 7 = -8, we can solve the equation by isolating x.
First, we can add 7 to both sides of the equation to eliminate the constant term on the left side:
2x - 7 + 7 = -8 + 7
This simplifies to:
2x = -1
Next, we divide both sides of the equation by 2 to solve for x:
(2x)/2 = (-1)/2
This gives us:
x = -1/2
Therefore, the value of x in the expression 2x - 7 = -8 is -1/2.
Hence, the correct answer is D. -1/2.
In regular Hexagon the size of each angle is:
A. 900
B. 1080
C. 1200
D. 1350
Explanation: In a regular hexagon, each interior angle has the same measure. To find the measure of each angle in a regular hexagon, we can use the formula:
Interior angle = (n-2) × 180° / n
where n is the number of sides of the polygon.
For a regular hexagon (n = 6), we can substitute the value into the formula:
Interior angle = (6-2) × 180° / 6
= 4 × 180° / 6 = 720° / 6 = 120°
Write in expression six times the sum of x and five.
A. 6(x + 5)
B. 6 + 5x
C. 6x + 5
D. 6x + 5x
