Answer:
r = 12
Step-by-step explanation:
DG + GM = DM , substitute values
r + 3 + 4r - 28 = 35 , that is
5r - 25 = 35 ( add 25 to both sides )
5r = 60 ( divide both sides by 5 )
r = 12

Answer:
The answer to your question is Volume left = 472.5 cm³
Step-by-step explanation:
Data
7 cm x 5 cm x 18 cm
She drank 1/4
Volume left = ?
Process
1.- Calculate the volume of the rectangular prism
Formula
Volume = length x width x height
Substitution
Volume = 7 x 5 x 18
Result
Volume = 630 cm³
2.- Divide the volume by 4
630 /4 = 157.5 cm³
3.- Subtract 157.5 from the original volume
630 - 157.5 = 472.5 cm³
Answer: 2.12 seconds
Step-by-step explanation:
From the question, we are informed that Josie ran a lap in 45.23 seconds while Erica ran a lap in 43.11 seconds.
To calculate the extra amount of time it took Josie to complete the lap, we subtract Erica's time from Josie's time. This will be:
= 45.23 seconds - 43.11 seconds
= 2.12 seconds
