DT BREAKFAST ๐Ÿฅž QUESTIONS (Maths)๐Ÿ‘‡๐Ÿ•Š๏ธ๐Ÿ˜‹โœจ


1. Expand the expression:
(xยฒ-2x-3)(xยฒ+x+1)

A. xโด-4xยฒ-5x-3
B. -xยณ-4xยฒ +5x-3
C. xโด-xยณ-4xยฒ-5x-3
D. xโด-4xยฒ-5x-3

Correct Answer: C โœ
(xยฒ-2x-3)(xยฒ+x+1)
= xยฒ(xยฒ+x+1) - 2x(xยฒ+x+1) -3(xยฒ+x+1)
= xโด + xยณ + xยฒ - 2xยณ - 2xยฒ - 2x - 3xยฒ - 3x - 3
= xโด - xยณ - 4xยฒ - 5x -3 ๐Ÿค

2. The Interior angles of a pentagon are: 180ยฐ, 118ยฐ, 80ยฐ, 78ยฐ, and xยฐ. The value of x is?

A. 75ยฐ
B. 108ยฐ
C. 120ยฐ
D. 84ยฐ

Correct Answer: D โœ
no. of sides of polygon = 5
Sum of int. <s of a polygon = (n -2)180ยฐ
For a pentagon, (5-2)180ยฐ = 540ยฐ
x = 540ยฐ - (180ยฐ + 118ยฐ + 80ยฐ + 78ยฐ)
x = 84ยฐ

*It was singly ____ who organized the event.*

A. Her

B. They

C. Them

D. She

*Correct Answer: D โœ…*

In English, when using "singly" to emphasize singularity or uniqueness, the pronoun that follows should match the singular form, which is either "she" or "her".

However, which of the pronouns are we to use; the subject or the object?

We are to go for the subject pronoun for the reason below:

A relative pronoun like "who" can only describe a subject, not an object. "Her" is an object while "she" is a subject.

Hence, "she" is the correct option.

2. The sum of two numbers is 6 and the difference is 2. Find the numbers.

Solution

Let the numbers be x and y.

x + y = 6 .... (1)
x - y = 2 ....(2)

Eq(1) + Eq(2)
2x = 8
x = 4

Sub 4 for x in (1)
x + y = 6
4 + y = 6
y = 6 - 4
y = 2

The numbers are x = 4 and y = 2.

3. The sum of two books and a pencil is ยฃ6.00. The difference of cost between 3 books and 2 pencils is ยฃ2.00. Find the cost of a book and a pencil.

Let the cost of a book be x and that of a pencil be y.

2x + y = 6.....(1)
3x - 2y = 2.....(2)

Multiple (1) by 2
4x + 2y = 12..... (3)

Add (2) and (3)

=> 7x = 14
x = 2

Sub 2 for x in (1)
4 + y = 6
y = 2

The cost of a book and a pencil is ยฃ2.00 each.

1. Choose the option that best best completes the gap(s).

Olu brought his clothes and those of his _.

A) senior brother's
B) elder brothers
C) elder brother's
D) senior brother

The correct answer is B.โœ
It's "elder brothers", not "elder brother's." 'Those' is a pronoun referring to the clothes. Note that 'of' is serving a possessive function there. Thus, the phrase, "elder brother", cannot take the possessive " 's".


2. Choose the option that best completes the gap(s).

Everybody is allowed to _ his/her view on state matters?

A) air
B) hear
C) show
D) share

The correct answer is A.โœ
To air your opinion is to make your idea, opinion or argument known.

1. In photo-emission, the number of photoelectrons ejected per second depends on the

A) Intensity of the beam
B) Frequency of the beam
C) Work function of the metal
D) Threshold frequency of the metal

*The correct answer is A.*๐Ÿ’ข
_In the photoelectric effect, light incident on the surface of metal causes electrons to be ejected. The number of emitted electrons and their kinetic energy can be measured as a function of the intensity and frequency of the light._

_The intensity affects the number of electrons, and the frequency affects the kinetic energy of the emitted electrons. The number of electrons emitted per second (i.e. the electric current) is independent of frequency and increases linearly with the light intensity._

2. The mechanism of heat transfer from one point to another through the vibration of the molecules of the medium is

A) conduction
B) diffusion
C) convection
D) radiation

*The correct answer is A*โœ๐Ÿ’ข
_In heat conduction, energy is transferred from molecule to molecule by direct contact; the molecules themselves do not necessarily change position, but simply vibrate more or less quickly against each other._

*DT BREAKFAST PUTME QUESTIONS (Biology)*โœ๐Ÿ‘”๐Ÿงฌ๐Ÿฆ 



1. Leguminous plants, e.g Mucana, are usually planted in cultivated farmlands because they


A) enrich the soil with phosphates
B) provide animals with food
C) enrich the soil with organic nitrogen
D) protect the soil from being over-heated
E) protect the micro organisms in the soil

*The correct answer is C.*โœ
_Leguminous plants are grown alternately with non-leguminous plants to restore the fertility of the soil. Legumes have bacteria on nodules which are on the roots of the plant. The bacteria on the nodules takes nitrogen from the air and fixes it into the soil, so that other plants that require nitrogen can use it as well. This nitrogen cycle is used in what farmers call a crop rotation._


2. Oxygen from the atmosphere reaches the mammalian blood stream through one of the path indicated below. Indicate the correct path, a = mouth, b = trachea, c = bronchiole, d = nostril, e = bronchus, f = alveoli

A) a โ†’ b โ†’ e โ†’ f โ†’ d
B) b โ†’ d โ†’ f โ†’ e โ†’ c
C) d โ†’ b โ†’ e โ†’ c โ†’ f
D) b โ†’ a โ†’ f โ†’ e โ†’ c
E) f โ†’ e โ†’ c โ†’ d โ†’ c

*The correct answer is C.*โœ
_When we breathe in, air moves from our nostril to our trachea and bronchus and then to the bronchiole. Oxygen from the air then enters small air sacs, called alveoli, in the lungs. Oxygen diffuses from there into the bloodstream._
