Arectangular prism of volume 84 cm3 has a mass of 760 g. what is the density of the rectangular prism?

Answer : The density of the rectangular prism is, 9.05 g/ml.

Explanation :

Density : It is defined as the mass contained per unit volume.

Formula used :

Given :

Mass of rectangular prism = 760 grams

Volume of rectangular prism =

Now put all the given values in the above formula, we get:

Thus density of the rectangular prism is, 9.05 g/ml.

linda: 3 ; laura: 15

step-by-step explanation:

note that linda + laura's age is 18, and that linda is 12 years younger than her sister.

let "linda" = x , "laura" = y:

x + y = 18

x = y - 12

first, plug in y - 12 for x in the first equation:

(y - 12) + y = 18

simplify.

2y - 12 = 18

isolate the variable (y). note the equal sign, what you do to one side, you do to the other. do the opposite of pemdas. first add, then divide.

2y - 12 (+12) = 18 (+12)

2y = 18 + 12

2y = 30

(2y)/2 = (30)/2

y = 30/2

y = 15

next, plug in 15 for y in the second equation (the other equation would work too).

x = y - 12

x = (15) - 12

x = 3

linda's age is 3, laura's age is 15.
