Answer:

x+y=200

xy=9,600

Step-by-step explanation:

The diagram shows rectangular parking lot with sides of x feet and y feet.

1. The area of the rectangle is given by

A=Length \times Width

A = xy -------------------------(1)

We are given that the area of the parking lot is 9,600\ ft^2, then

eq(1) becomes

9,600 = xy ---------------------(2)

2. A parking lot has a 200ft fence built along two adjacent sides of lengths x and y, then

Then the perimeter of the two adjacent sides

x+y=200 ---------------------------------(3)

Thus ,The system of two equations are

x+y=200

xy=9,600

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.

Mr mehra spends 30% of his income in food 10% on charity 25% and is left with 15750 what is his salary? find his savings

nalin [4]

Answer:

Mr mehra's salary is 26250

Step-by-step explanation:

suppose,

Mr mehra's salary is x

so,

He spends in food = 30% of x

=(30/100) . x [x%=x/100]

= 30x/100

=3x/10

He spends in charity =10% of x

=10x/100

=x/10

Money left = 15750

so,

x = 3x/10 + x/10 + 15750

⇒x - 3x/10 - x/10 = 15750

⇒(10x-3x-x) /10 = 15750

⇒6x/10 = 15750

⇒6x=157500

⇒x = 157500/6

⇒x = 26250

∴Mr mehra's salary is 26250
