What percent of 180 is 45?
4.5
18
22
25

Hi there! :)

The answer is D. 25% of 180 is 45.

Step-by-step explanation:

Let's replace "what percent" with the letter "x" because it's what we are looking for.

The word "of" is the same thing as a multiplication sign, which means that the sentence "What percent of 180 is 45?" can turn into "x times 180 is 45".

The word "is" is the same thing as an equation sign, wich means that you can write this as an equation:

x × 180 = 45

180x = 45

Now all you have to do is solve this equation by isolating "x" to find your

180x = 45

Divide each side of the equation by 180 → 45 ÷ 180 = 0.25

x = 0.25

0.25 = 25 ÷ 100 = 25%

There you go! I really hope this helped, if there's anything just let me know! :D

回答：

答えはDです。180の25％は45です。

ステップバイステップの説明：

「何パーセント」を文字「x」に置き換えましょう。これが私たちが探しているものだからです。

「of」という単語は乗算記号と同じです。つまり、「180の何パーセントが45ですか？」という文です。 「x×180は45」になります。

「is」という単語は方程式の記号と同じものです。これは、これを方程式として記述できることを意味します。

x×180 = 45

180x = 45

今、あなたがしなければならないのはあなたの答えを見つけるために「x」を分離することによってこの方程式を解くことです：

180x = 45

方程式の各辺を180→45÷180 = 0.25で割ります

x = 0.25

0.25 = 25÷100 = 25％

18.36. give me brainliest!

step-by-step explanation:

you have to multiply 1.53 by 12 so the equation is 12x1.53 and then that is your answer.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
