問2の解説を詳しくお願いします。

次の英文は、裕太(Yuta)が書いたものである。これを読んで、後の各問に答えよ。 "So, let's continue making an introduction about your fathers," said our English teacher, Mrs. Yashima one month ago. This class was Dmind-numbing, and I was thinking of the way to kill the time during the class. 4 I didn't know much about my father He was always busy working, so I didn't have any memories of playing with him at all. He came home late at night, woke up earlier than me, and left for his workplace without having breakfast. On weekends, he was always watching news programs which never interested me. When I looked out of the window, a friend of mine who was living near my home was playing catch with his father, and I projected myself on him. When we were having dinner, he never asked me any nice question. He always said to me, "How are the school and the club going?" I only said, "Not bad," because I thought that he had no interest in my school life or club activity. I didn't know about my father well, but I remember the other face of him. He sometimes repaired things in our home such as the TV set, chair, or bicycle. I wasn't interested in it at all until a neighbor told me a story about my father. She always took care of me when my parents were busy. "Your father is a good person," she said. "He always repairs broken things with a smile. It was just like magic." And she gave me some cookies. I knew about my father a little. The other day, I visited a factory as a part of social study class, and a man spoke to me, "Oh, your last name is..., are you his son? When I was working for another company with him, he took good care of me. He sometimes scolded me, but taught me a lot of things. So, I respect him so much." I knew about my father well. When I told my father about the man, he said to me, "Keep the friendship all the time. If you give a hand to someone, the person will give you a hand back someday. Just remember it." At that time, I understood that my father was a hard worker and he was respected by many people. Though he was a serious and silent person, I felt I knew him for the first time. 2022(R4) LAMANG

(2)がわからないです、

8(2022年) 大阪府 (一般入学者選抜) 3 Fさんは、右の写真のように大きさの異なる2種類のコーンがそれぞれ積ま れているようすに興味をもち、図I. 図IIのような模式図をかいて考えてみた。 図1は、1個の高さが320mmのコーン Aだけを積んだときのようすを表す 模式図である。「コーン Aの個数」が1のとき「積んだコーン A の高さ」は 320mm であるとし、 「コーンAの個数」が1増えるごとに「積んだコーンAの 高さ」 は 15mmずつ高くなるものとする。 図ⅡIは、1個の高さが150mmのコーンBだけを積んだときのようすを表す模式図である。 「ンBの個数」が1のとき 「積んだコーンBの高さ」は150mm であるとし, 「コーン Bの個数」 1増えるごとに「積んだコーンBの高さ」は10mmずつ高くなるものとする。 次の問いに答えなさい。 図 I 320mm 15mm 15mm 15mm→ X 積んだコーン A の高さ y 図ⅡI 1 2 320 335 150mm 4 (ア) 10mm→ 10mm 10mm (1) 図Iにおいて,「コーンAの個数」がæのときの「積んだコーン A の高さ」をymm とする。 ① 次の表は,とyとの関係を示した表の一部である。 表中の(ア), (イ)に当てはまる数をそれぞ れ書きなさい。 (ア) ( )(イ) ( ) ..... 積んだコーン B の高さ 8 (イ) ) 4 次の [I] 辺形 に D F か ( (2 を自然数として,yをxの式で表しなさい。 ( (3) y = 620 となるときのxの値を求めなさい。 ( (2) FさんがコーンAを図Iのように,コーンBを図IIのようにそれぞれいくつか積んでいったと ころ,積んだコーンAの高さと積んだコーンBの高さが同じになった。 「コーンAの個数」をsとし, 「コーンBの個数」をt とする。 「コーンAの個数」と「コー 「Bの個数」との合計が39であり,「積んだコーンAの高さ」と「積んだコーンBの高さ」 とが じであるとき,s,t の値をそれぞれ求めなさい。 s の値 ( )tの値( )
