Answer:
The mass of the object is 2.6 grams
Step-by-step explanation:
The density of an object is the ratio between its mass and its volume
The equation of the is d =
, where
Let us use this equation to solve the question
∵ An object has a density of 1.3 g/cm³
∴ d = 1.3 g/cm³
∵ Its volume is 2 cm³
∴ V = 2 cm³
→ Substitute them in the equation of the denisty above
∵ 1.3 = 
→ Multiply both sides by 2
∴ 2 × 1.3 = 2 × 
∴ 2.6 = m
∴ The mass of the object is 2.6 grams
Answer:
5 BAGS OF FLOUR
7 1/2 ÷ 1 1/2 = 5
Based on the given conditions, formulate: 7 1/2 / 1 1/2 Find common denominator and write the numeral.
Answer:
The answer is 2.
Step-by-step explanation:
Given: - 6 - (-6) + 7 + ( - 4) + ( - 1)
= - 6 + 6 + 7 - 4 - 1
= 6 + 7 - 6 - 4 - 1
= (6 + 7) - (6 + 4 + 1)
= 13 - 11
= 2
Hence, the answer.
