Answer:
The mass of the grains = 120 ± 1 g
Step-by-step explanation:
we are given the following:
Total mass of container + grains = 185 grams
Mass of container = 65 grams
Therefore, mass of grains is calculated as follows:
Mass of grains = ( Mass of container + grains) - mass of container
= 185 - 65 = 120 grams.
since the scale has an absolute uncertainty of 1 g, the mass of the grains is written as 120 ± 1 g
The answer is 25 because u said it was 25
You should use the ratio so
2/ 4 = 6.5 / n
n= 6.5 x 4 / 2 = 13 inches
2- for two hours ------> four inches of snow
for x hours -----> y inches of snow
the equation is
2/4 = x/ y
x= 2y / 4
for x is the hours and y is the inches
exercice 2
5 gr granula ----------------------> 1750 calories
2 gr granula ----------------------> n ?? calories
by cross multiplication
n = 2 x1750 / 5 = 700 calories .
2-
she wants to eat 175 calories so
u put granula under granula and calories under calories to make this cross
<span>5 gr granula ----------------------> 1750 calories
</span>??? m granula ---------------------> 175 calories
<span>by cross multiplication </span>
m = 175 x 5 / 1750 = 0.5 gr of granula
