Answer:
The total number of barcodes printed by both machines during these two days is given by
Step-by-step explanation:
Given : Brent has two barcode printing machines. Each machine can print 25 barcodes per minute. On day 1, only the first machine was used, and it printed 95 barcodes. On the following day, the first machine printed for x minutes and the second machine printed for y minutes.
To find : Which expression shows the total number of barcodes printed by both machines during these two days?
Solution :
On day 1,
Only the first machine was used, and it printed 95 barcodes.
So, On 1 day the number of barcodes print = 95
On day 2,
The first machine printed for x minutes and the second machine printed for y minutes.
We have given that, Each machine can print 25 barcodes per minute.
In x minutes it print 25x barcodes.
In y minutes it print 25y barcodes.
So, On 2 day the number of barcodes print is
The total number of barcodes printed by both machines during these two days is given by

Answer:
Frank can put 5 cubes in the box.
Step-by-step explanation:
Formula:
Mass = Volume × density.
1 cubic centimetre = 0.001 liter= 1 millilitre
Given that,
Frank purchase a new ice box having 2 kg capacity.
So,the mass of the cubes is 2 kg.
Each ice cubes measured 3.5 cm by 3.5 cm by 3.5 cm.
The volume of a cube is =
The volume of a each ice cubes is = cm³
= 42.875 ml
The ice cubes have a density of 0.914 g/ml
The mass of each cubes are
=volume of each ice cubes × density
=42.875 ml ×0.914 g/ml
=39.18775 gram.
Let x number of ice cubes he can put in the box.
The mass of x cubes is = 39.18775x grams.
2 kg= 2,000 gram [ since 1 kg= 1000 gram]
According to the problem,
39.18775x=2,000
Frank can put 5 cubes in the box.
