2) Aliyah had $24 to spend on seven pencils.

Mathematics
1 answer:
Nata [24]4 years ago
6 0

Answer:

Step-by-step explanation:

she had $ 24 to spend on 7 pencils....and after buying them she had $ 10.

this means that the total of the pencils was (24 - 10) =  $14

and assuming each pencil cost the same price....

14/7 = $ 2 per pencil

or u can set it up as an equation

24 - 7x = 10....with x being the price of a pencil

24 - 10 = 7x

14 = 7x

14/7 = x

2 = x <==

Use the information frompart a to write an equation representing the number of colories burned each minute while bowling. Let m
Fofino [41]

Answer:

To find the number of calories burned:

Find the Metabolic Equivalent of Task (MET) value of the task.

Calculate the number of calories burned per minute. (MET x body weight in kg x 3.5) / 200.

Multiply the calories burned per minute by the number of minutes of activity.

Now, as per the question, weight is 125 pounds (lb), we will convert the weight in kilogram (kg) which is 1 lb = 0.453 kg, it means 125 lb = 56.7

Now we have to find the MET,

A metabolic equivalent (MET) value is a measurement of the energy cost of a specific physical activity for a specific period of time.

For example. A MET of 1 would be roughly equivalent to a person's energy expenditure from sitting still in a room temperature and not actively digesting food.

As per the Calorie guide value of MET for bowling is 3.9

Now the overall formula is

Calorie Burn (x) = ((MET * body weight in kg * 3.5) / 200) * (Number of minutes) m

x = ((3.9*56.7*3.5)/200) * m

Finally, x = 3.87 m represents the number of calorie burned (x) while bowling m minutes.
