Vedmedyk [2.9K]

Answer:

$2 for soda and $1.5 for a bottle of water

Step-by-step explanation:

You start by turning both situations into an equation

Let x represent bottles of water and y represent sodas

Saturday:

40x+25y=110

Sunday:

50x+45y=165

You then want to start by cancelling out the x in this equation, to do that you want 40x to become -50x so you:

50÷40=1.25

You then times the whole equation by -1.25

40x+25y=110

×-1.25

-50x+-31.25y= -137.5

You then add this equation by Sunday's equation

50x+45y=165

-50x+-31.25y=-137.5

          13.75y=27.5

You now want to make the co-efficient of y a whole number (for example 15) so you divide 15/13.75=1.09 recurring

13.75y=27.5

×1.09 recurring

    15y=30

15y/15=30/15

     y=2

Now that we know y = 2

We can use either Saturday or Sunday's equation to figure out the value of x

Let's use Sunday's:

50x+45×2=165

50x+90=165

50x+90-90=165-90

50x/50=75/50

x=1.5

Let's check our answer with Saturday's equation

40×1.5+25×2=110

This equation is correct

Therefore the prices for each beverage option is $1.5 for a bottle of water and $2 for a soda

konstantin123 [22]

Answer:

AB = 5.6 cm

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 62°

Hypothenus = BC = 12 cm

Adjacent = AB =?

The lenght of side AB can be obtained by using Cos θ ratio. This is illustrated:

Cos θ = Adjacent / Hypothenus

Cos 62 = AB / 12

0.4695 = AB / 12

Cross multiply

AB = 0.4695 × 12

AB = 5.6 cm

Thus, length AB is 5.6 cm

at a school there are 10 students taking only chemistry, 9 students taking only physics 5 students taking both, and 16 students
sveticcg [70]

Answer:

If there are 10 students taking only chemistry, 9 students taking only physics, and 5 students only taking both chemisty and 16 students are taking neither; I would add 10+9+5+16=40 (total students) and divide 10/40 (25% chemistry) 9/40 (22.5% physics) 5/40 (12.5% both) 16/40 (40% neither)

Step-by-step explanation:

1. Determine a single event with a single outcome.

2. Identify the total number of outcomes that can occur.

3. Divide the number of events by the number of possible outcomes.
