J is not a function.

for y to be a function of x, it needs to have every input x value mapping to one, and only 1, output y value.

we see that for graph J, x = -3 maps to both -3 and -2.

can't be a function

tony spent $60.54 and bought 3 packs of notebooks and a calculator. how much does a pack of notebooks cost if a calculator costs

Amiraneli [1.4K]

First you need to find out the remaining value after he bought the calculator this would be 14.67.

60.54 - 45.87= 14.67

Next youll assume the packs of notebooks all cost the same and divide by 3

14.67 / 3 = 4.89

He spent 4.89 on one pack of notebooks

A light bulb consumes 2700 watts an hour in 4 days and 12 hours. How many watts does it consume in a day

yaroslaw [1]

Answer:

The light bulb will consume 600 watts in one day.

Step-by-step explanation:

Let us suppose the light bulb is continuously ON.

As a light bulb consumes 2700 watts an hour in 4 days and 12 hours.

4 days and 12 hours = 96 hours + 12 hours = 108 hours

So, a light bulb consumes 2700 watts in 108 hours.

Hence,

A light bulb consuming the watts per hour will be: 2700/108 = 25 watts

As a light bulb consumes 25 watts in one hour, there are 24 hours in a day.

Light bulb consuming total no of watts in a day = 25 × 24 = 600 watts

Therefore, the light bulb will consume 600 watts in one day.

<u>2ND METHOD</u>

4 days and 12 hours = 4.5 days

Total no of watts cosumed by a light bulb in 4.5 days = 2700 watts

Total number watts consumed in a day = 2700 / 4.5 = 600 watts.

Therefore, the light bulb will consume 600 watts in one day
