Answer:
7.7 pounds = 3.5 kilograms
Step-by-step explanation:
Given that,
Weight of a gallon of liquid = 7.7 pounds
We need to find weight in kilograms.
We must know the relation between pounds and kilograms and it is as follows :
1 kilogram = 2.20 pounds
or
1 pounds = (1/2.2) kilograms
7.7 pounds = (7.7/2.2) kilograms
= 3.5 kilograms
Hence, 7.7 pounds is equal to 3.5 kilograms.
The formula for area of a triangle is: 1/2 x base x height.
You are given the height of 4 and the area of 4.
Replace those in the formula and solve for x ( base)
4 = 1/2 x base x 4
Divide both sides by 4:
1 = 1/2 x base
Multiply both sides by 2:
2 = base
x = 2
