Answer:
Using the ratio table the dogs weight is:
30 pounds = 13.5 kilograms
Step-by-step explanation:
For this case we have the following conversion:
20 pounds = 9 kilograms
To use the table what we must do is find another relationship that allows us to find the weight in kilograms for 30 pounds.
For example, half the weight in pounds is half the weight in kilograms.
Therefore, the given conversion is:
10 pounds = 4.5 kilograms
So, for 30 pounds, we multiply this last ratio obtained by three on both sides:
30 pounds = 13.5 kilograms
Then, the table is:
Pounds 10 20 30
Line 3.. It removed the 'x' from the 10, and it's adding, not subtracting.

Answer:
<u>x = 3</u>
Step-by-step explanation:
We should know that:
A straight segment joining the middle of two sides in a triangle is parallel to the third side and equal to half of it.
So,
3x + 1 = (1/2) * 20 = 10
3x = 10 - 1 = 9
x = 9/3 = 3
<u>So, the value of x = 3</u>
Answer:
640 m^2.
Step-by-step explanation:
There are 6 faces to this prism:
2 with dimensions 20*10 = 2*200 = 400 m^2
and 2*20*4 = 160 m^2
and 2*10*4 = 80 m^2
Total surface area = 400+169+80 = 640 m^2.
