Ini apa we jawabannya pelasee​
kupik [55]

Answer:

<h3></h3><h2><u>kualitas terjemahannya mungkin tidak bagus. Jadi lihat 2 baris terakhir jika Anda tidak mengerti.</u></h2>

Jadi jumlah derajat tidak masalah. Mereka masih akan menempuh jarak yang sama.

Karena Anda mengatakan bahwa ekspres Marina berjalan pada 40 km / jam dan kami melakukan 2 jam. 40 * 2 = 80 km. Untuk Dumai Anda melakukan hal yang sama, 48 * 2 = 96.

Marina berjalan sejauh 80 km

Dumai berjarak 96 km

5. Find the squares of the following numbers by using the formula of (a + b)' or (a-b]². c) 98​
Dmitrij [34]

98^2 = (100-2)^2

Using (a-b)^2, we have

= (100)^2-2(100)(2)+(2)^2

= 10000-400+4

= 10004-400

= 9604

The answer is 9604.

a sum of RS 500 is in the form of denominators of RS5 &amp; RS 10..if the total no. of notes is 90 ,find the no. of notes of eac
Katarina [22]
Let rs.5 denominations be x , then rs 10 denominations will be 90-x

then total amount 5x + 10(90-x) which is rs.500

 5x + 10(90-x) = 500

900 - 5x = 500
400 = 5x
therefore x = 80
          therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10
