Answer:
48
Step-by-step explanation:
48
Let the tens digit be x.
Hence, the units digit will be 2x
Number =10×(x)+(2x)=12x
When 36 is added to the number, the new number formed =12x+36
As the digits are reversed, we can also write the new number as 10×(2x)+x=21x
Hence,
12x+36=10×(2x)+x
⇒12x+36=21x
⇒21x−12x=36
⇒9x=36
⇒x=4
Hence, the original number =12x=12×4=48
Change iny\change in x
change in y=4.4-2.2=2.2
change in x=11-5.5=5.5
slope=2.2\5.5=0.4
7. You have the equator's length of four planets, the distances are given in kilometers
8. Estimation for the Earth: 40.000 km. Jupiter: 400.000. These approximations come from the nearest whole number for each.
9. The relation is that if the Jupiter equator's length is divided by ten, you will get the Earth's equator length, which means that Jupiter's equator is ten times bigger than the earth.
Answer:
3 : 7
Step-by-step explanation:
Let the radii be 3x, 7x.
Circumference = 2πr, where r = radius
Thus, ratio of circumference:
2 × π × 3x : 2 × π × 7x
= 3 : 7
( as 2, π and x get cancelled out)
