One grain of this sand approximately weighs 6 x 10^-6g. b) How many grains of sand are there in 7200 kg of sand?
Give your answer in standard from.

1.2×10¹² grains

Step-by-step explanation:

1 grain = 6×10⁻⁶ g

7200 kg = 7200000 g = 7.2×10⁶ g = 7.2×10⁶ ÷ 6×10⁻⁶ = (7.2÷6)×10⁶⁻ ⁽⁻⁶⁾ =1.2×10¹² grains

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition.
