Which of these are not a factor of 25 x 36 x 121? Options: 3 x 4 x 5, 5 x 6 x 11, 5 x 7 x 9, 5 x 9 x 11

Back

5 x 7 x 9

Answer explanation

To find the factors of 25 x 36 x 121, we can break them down: 25 = 5^2, 36 = 6^2, 121 = 11^2. The product 5 x 7 x 9 includes 7, which is not a factor of the original product, making it the correct answer.

How can (A^2)^3 be represented?

Back

a^2 x a^2 x a^2

Answer explanation

The expression (A^2)^3 means A^2 multiplied by itself three times, which can be written as A^2 x A^2 x A^2. Thus, the correct representation is a^2 x a^2 x a^2.

DEF(triangle)

CANNOT be a /an

Isosceles

,

Right angled

,

Equilateral

,

Obtuse angled

Back

Equilateral

Answer explanation

An equilateral triangle has all sides equal, which means it cannot be classified as isosceles (two sides equal) or right-angled (one angle 90 degrees). Thus, DEF(triangle) cannot be an equilateral triangle.

Find the area of the shaded part

Back

42cm^2

Answer explanation

To find the area of the shaded part, we calculate the total area and subtract the unshaded area. The calculations yield 42 cm² for the shaded area, confirming that the correct answer is 42 cm².

Ratio of chairs with wheels to without if 7/9 of the chairs have wheels.

Back

7:2

Answer explanation

In the office, 7/9 of the chairs have wheels, meaning 2/9 do not. The ratio of chairs with wheels (7) to those without (2) is 7:2, making the correct answer 7:2.

A number x when divided by 6 leaves the remainder as 0. What will be the remainder if it was divided by 2?

Back

0

Answer explanation

Since x leaves a remainder of 0 when divided by 6, it is a multiple of 6. All multiples of 6 are also multiples of 2, meaning when x is divided by 2, the remainder will also be 0.

A number P is obtained by multiplying a whole number M by 5 then adding it with 6. What will be the REMAINDER if P is divided by M + 1?

Back

M + 1

Answer explanation

Given P = 5M + 6, when divided by M + 1, we can rewrite P as 5M + 5 + 1. This shows that P is divisible by M + 1, leaving a remainder of 0.

In triangle PQR, angle Q = 50° and angle R = 75°. Which of these is true about the sides of the triangle? Options: QR=PQ, PQ

Back

PR

Answer explanation

In triangle PQR, angle Q is 50° and angle R is 75°. By the triangle inequality, the side opposite the largest angle (angle R) is the longest. Thus, PR < QR is true.

If “2n” is the form of writing any even integer then which of these will definitely be odd? Options:

n-1

,

2n-1

,

2(n+1)

,

2n+2

Back

2n-1

Answer explanation

Since 2n is even, subtracting 1 from it (2n-1) results in an odd number. The other options either remain even or become even when simplified. Thus, 2n-1 is definitely odd.

If ⭐️ + ⭐️ + ⭐️ + 🌙 = 80

And ,🌙 + ⭐️ = 30

Then what is the value of 🌙

Back

5

Answer explanation

From the equations, ⭐️ + ⭐️ + ⭐️ + 🌙 = 80 and 🌙 + ⭐️ = 30, we can express ⭐️ as 30 - 🌙. Substituting this into the first equation gives 3(30 - 🌙) + 🌙 = 80. Solving this leads to 🌙 = 5.
