Answer:
50 pounds = 22.7 kilograms
Step-by-step explanation:
Yes both are correct
Sabine :
2.2 pounds = 1 kilogram
1 pound = 1/ 2.2 kilogram = 0.454 kilogram
50 pounds = 50 * 0.454 =22.7 kilograms
To find equivalent ratios just factor the same number to both numerator and denominator. I will make the ratios simple by multiplying 2/2 and 3/3 to the originals. To check, set as fraction and cross multiply and you should have the same number. I will show you how to check by doing it to the first ratio.
8:5 16:10 24:15
Check:
8/5 = 16/10
(8)(10)=(5)(16)
80=80
8/5=24/15
(8)(15)=(5)(24)
120=120
4:19 8:38 12:57
6:23 12:46 18:69
This is a simple subtraction question,
y is a variable, so Jaron could be any age and still be 5 years older than dawn.
lets say Jaron is 20, since he is five years older, we can subtract 5 from 20 and get 15
so
y = 20
d = 15
d = dawn's age
You basically can solve for hypothetical sides of this triangle using sohcahtoa backwards. In the first column, it says that adjacent/hypotenuse = .97. We can come up with two values that satisfy this equation. For example, the adjacent side can be .97 and the hypotenuse can be 1. These values don't matter as long as adjacent/hypotenuse is .97.
The second column tells us that opposite/hypotenuse = .26. At this point, we already have a hypothetical hypotenuse with a length of 1, so we can plug that in and find that the opposite side of C is .26.
Now that we have a hypothetical triangle with sides .97, .26, and 1, you can use these values as well as sohcahtoa to solve for the rest with respect to angle A. Keep in mind that the line AB is .26 and that the line BC is .97.
Do you just want the mathematical definition of magnitude <span />
