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

To solve the problem we must know about Sine Rule.
<h3>What is Sine rule?</h3>The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,
where
- Sin A is the angle and α is the length of the side of the triangle opposite to angle A,
- Sin B is the angle and β is the length of the side of the triangle opposite to angle B,
- Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.
The value of w is 4.0 cm.
Given to us
- VW = 3.3 cm,
- ∠U = 31°,
- ∠W = 39°,
Substitute the values,
w = 4.03224 cm ≈ 4.0 cm
Hence, the value of w is 4.0 cm.
