Answer:
y is also doubled.
Step-by-step explanation:
Direct proportionality between 
and 
means that
or
,
which indicates a linear relationship between and because they are related by a constant.
Therefore, if x is doubled, then the new value of is 
The new value of is 2 times the previous; therefore, is doubled as is doubled.

Answer:
8100g(i.e 8.1kg) is 5.8kg more than 2.3kg
Step-by-step explanation:
Let us convert 8100g to kg.
1000g = 1Kg
8100g = 8100/1000 = 8.1Kg
Now, to know how much is 8100g(i.e 8.1kg) than 2.3kg, we'll find the difference between them as follows
8.1 — 2.3 = 5.8
Therefore, 8100g(i.e 8.1kg) is 5.8kg more than 2.3kg
Answer:
4.5
Step-by-step explanation:
To find the hypotenuse of a right triangle, we use Pythagorean's Theorem which states that 
. Plugging in the values of the two legs given, we get 
. We can take the square root of each side and get that 
.
