Explanation

To find when both grades visit the lab on the same day again, we need to find the Least Common Multiple (LCM) of 16 and 30.

Multiples of 16: 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240

Multiples of 30: 30, 60, 90, 120, 150, 180, 210, 240

The LCM of 16 and 30 is 240.

Explanation

"The" is used for a specific person or thing known to the speaker and listener.

"Boy in red shirt" is a specific boy, so "The" is appropriate.

Explanation

To find the fourth proportional, let's denote it as x. The proportion will be:

3 : 9 = 7 : x

We can cross-multiply:

3x = 9 × 7

3x = 63

x = 63 / 3

x = 21

Explanation

Given:

Side of square = 1200 cm

Width of strip = 10 cm

Side of larger square (including strip) = 1200 + 2(10)

= 1200 + 20

= 1220 cm

Area of larger square = 1220² = 1488400 cm²

Area of square = 1200² = 1440000 cm²

Area of strip = Area of larger square - Area of square

= 1488400 - 1440000

= 48400 cm²

Explanation

A transitive verb requires a direct object to complete its meaning — here, "closed" acts on "the door".

The verbs sat, smiled, arrived are intransitive, meaning they do not take a direct object.

Explanation

The denotative meaning is the literal or dictionary definition of a word — in this case, a volunteer is someone who offers services willingly without pay.

Explanation

Child Centered Learning focuses on the interests, needs, and developmental level of the child.

It promotes active participation, exploration, and self-directed learning.

Explanation

In a Passive Learning Environment, students receive information and respond to stimuli with little active engagement.

This aligns with the stimulus-response method where learning is measured by correct reactions to teacher prompts.
