①、②、④は分かったのですが③、5が解説を見たのですがよく分かりません。誰か分かりやすく教えてくださいお願いします🙇‍♀️

ADL 内の先生と生徒の会話文を読んで、下の内の生徒が完成させた【証明】の から⑤に当てはまる数や式をそれぞれ答えなさい。 しからし 「姓 「一の位が0でない 900未満の3けたの自然数をMとし,Mに99をたしてできる自然 数をNとすると、Mの各位の数の和とNの各位の数の和は同じ値になるという性質が あります。例として583で確かめてみましょう。」 生徒「583の各位の数の和は5+8+3=16です。 583に99をたすと682となるので,各位の DAG 数の和は 6 +8 +2=16で同じ値になりました。」 先生「そうですね。 それでは、Mの百の位、十の位, 一の位の数をそれぞれ a,b, そして、この性質を証明してみましょう。 a,b,cのとりうる値の範囲に気をつ MとNをそれぞれa,b,c を用いて表すとどうなりますか。」 生徒「Mは表せそうですが,NはM+99 で…・・ 各位の数がうまく表せません。」 先生「99を100-1におきかえて考えてみましょう。」 生徒が完成させた 【証明】 3けたの自然数Mの百の位、十の位一の位の数をそれぞれα, b,c とすると 1以上8以下の整数,bは0以上9以下の整数,cは1以上9以下の整数となる。 このとき *MOHOTO00S10 M= ① xa+ また,N=M+99 よ N=| 1 xa+ ② x 6 + c と表せる。 HOTO VOUS (2) | xb+c + 100-1 となるから N= ①² x ③ +② v x ④ + ⑤ Nの百の位の数は 十の位の数は4円 一の位の数は ⑤ となる よって、Mの各位の数の和とNの各位の数の和はそれぞれ a+b+c となり、同じ値 pal ob 26 TERMASU HALL SMA

The prototype 4x2 bricks have been made from PET plastic from ( 12 ) bottles with additives to give them the strength of standard Lego parts, and are the result of three years of ( 13 ) with 250 variations of materials.

Tim Brooks, vice-president for environmental ( 16 ) at Lego Group, said the biggest challenge was "rethinking and innovating new materials that are as ( 17 ), strong and high (18) as our existing bricks and fit with Lego elements made over the past 60 years". He added: "We're committed to playing our part in building a sustainable future for generations of children.

ⅡI. 次の英文の空欄 ( 11 ) から ( 30 )に入る最も適切な語句を, a.〜d.の中から 1つ選びなさい。 解答は解答用紙1枚目 (マークシート方式)の所定の解答欄にマークし なさい。 Huy Fong Foods, the southern California company that produces 20 million bottles of sriracha (1) annually, has experienced a low ( 11 ) of red jalapeño chili peppers in recent years made worse by spring's crop failure. What is the cause? ( 12 ) weather and drought (2) conditions in Mexico. It's not (13) chili peppers. Mustard producers in France and Canada said extreme weather caused a 50% reduction in seed production last year, ( 14 ) to a shortage of the condiment on grocery store shelves. Blistering heat, stronger storms, droughts, floods, fires and changes in rainfall (15) are also affecting the cost and availability of staples, including wheat, corn, coffee, apples, chocolate and wine. The climate crisis is increasing the intensity and ( 16 ) of extreme weather events — and it's putting food production at risk. "Almost everything we grow and ( 17 ) in the US is facing some climatic stress," said Carolyn Dimitri, nutrition and food studies professor at NYU. Wheat and other grain crops are particularly ( 18 ). In the Great Plains region, (19) most of the US's wheat is harvested, drought depressed the winter crop. Farmers are abandoning farmland used for growing winter wheat in the US-primarily in Texas and Oklahoma - at the highest rate since 2002. Meanwhile in Montana, flooding is (20) grain crops. The impact of the climate crisis on grain crops ( 21 ) beyond the US. In India, a fierce heatwave damaged the wheat crop ( 22 ) record-setting temperatures throughout the spring and summer.

Food production is a driver of the climate crisis and a (24) of it. ( 25 ) the food system will require a wide variety of actions, including increasing crop diversity, delivering climate (26) to farmers around the world, expanding conservation programs and offering growers insurance that pays out when an index such as rain or wind speed falls above or below a fixed limit. The Biden administration is supporting research into "climate-smart" agriculture, an approach to managing cropland, forest, fisheries and cattle that attempts to address the intersecting challenges of the climate crisis and food ( 27 ). In May, the UN secretary general, António Guterres, said that climate-related disasters and extreme weather were a driver of global hunger and that 1.7 billion people ( 28 ) by the climate crisis over the last decade. Experts say (29) action is taken, we can expect to see increased food prices, decreased availability and conflict over water, which will primarily affect poorer countries and low-income Americans, (30) everything from school lunches to food aid programs. © Copyright Guardian News & Media Ltd 2023 (1) sriracha (2) drought かんばつ 世界中で人気のチリソース
