Correct Answer: C. 20cm³

Correct Answer: D. Illiterate

Explanation

(a) Area of the shaded segment = area of sector XOY - area of triangle OXY.

\(\implies 504 = \frac{\theta}{360°} \times \pi r^{2} - \frac{1}{2} r^{2} \sin \theta\)

\(\implies 504 = \frac{90}{360} \times \frac{22}{7} \times r^{2} - \frac{1}{2} \times r^{2} \sin 90\)

\(504 = r^{2}(\frac{22}{28} - \frac{1}{2})\)

\(504 = \frac{2r^{2}}{7} \implies r^{2} = \frac{504 \times 7}{2} = 1764\)

\(r = \sqrt{1764} = 42 cm\).

(b) In the diagram, \(a_{1} = a_{2}\) (base angles of an isosceles triangle)

\(\therefore a_{1} + a_{2} = 2a_{1}\)

\(\therefore 2a_{1} + 109° = 180° \implies 2a_{1} = 180° - 109° = 71°\)

\(a_{1} = a_{2} = \frac{71°}{2} = 35.5°\)

Hence, \(< RQS = 66° + 35.5°\)

= \(101.5°\)

Correct Answer: B. encourages the regeneration of grasses

Explanation

When a controlled fire burns through a grassland, it can remove accumulated dead plant material and woody debris, known as thatch. Thatch can hinder the growth of new grass shoots and prevent sunlight and rainwater from reaching the soil surface. By removing the thatch through controlled burning, the fire creates a favorable environment for grass regeneration.

Dear Oladele,

I was delighted to learn that you've gained an admission into Prospect High School, a boarding secondary school. I am therefore writing to tell you about some problems you are likely to face as you go into secondary school. I will also tell you the possible ways of solving these problems so that you will not experience a hard time at school.

The first problem you may have to face is coping with the challenges ofbeing a student in a totally new environment socially and educationally. As secondary school is quite different from primary school, you are likely to face new challenges. This level ofeducation is more tasking and challenging than primary school education.This means thatyou will have to sit tight to meet the demands of this great step in your life.

You must always do your school works on time and treat them with all the seriousness they deserve. This will put you in a good stead with your teachers. Try to do all your assignments very well, because they are added up at the end of the term, as your continuous assessment marks. You must try to be the best, this you can achieve by diligent study

Secondly, you are likely to experience bullying from the older students.Take heart, as this is an inevitable aspect of what you should expect as a newcomer.This is one ofthe worst things a young child ofyour age could face. Bullying is when seniors deprive juniors ofwhat is rightfully theirs, punish juniors unnecessarily and simply maltreat them.

You may not offend a senior but because he wants to show that he is a senior, he may just decide to treat you badly. I know it is very painful, because it happened to me when I was in your shoes. On the day in question, I went to fetch water from a stream.As I was getting to the entrance ofthe hostel, a senior just accosted me telling me to carry the bucket of water to his room. This made me cry bitterly but there was nothing I could do.

Thirdly, you may likely face the problem of getting new friends. It would be impossible to enjoy your secondary school life without friends. As you know, I had lots of friends while in school and I really enjoyed it. What you just have to make sure you do is that you must choose good and hardworking friends. Your friends must be friends with good qualities.An adage thus goes: show me your friends and I will tell you who you are? As a good child, if you keep bad friends, you will soon be like them. This will therefore make you a disgrace to our family and I am sure you don't want to be that.

In order to solve these problems, look for a teacher who you like best and make him your foster father. He will monitor your activities in the school. You should also look for a senior most probably in senior secondary school three. You will have someone to run to if you are bullied.

You must also be nice to your mates, seniors, teachers and in general be a very good child so th.at you can make our parents proud.

How are you? I hope that you are getting ready for the new challenges. My regards to Toni Shala Jide Mummy and Daddy. I hope that Aunty Seun and her children are fine.

Yours sincerely,

Boluwaji.
