Horsepower and watts are units of measure of
Leni [432]

The 2 horsepower is equal to 1492 watts.

Given that horsepower and watts are units of measure of power and they are directly proportional such that 5 horsepower is equal to 3730 watts.

Horsepower is a unit of measurement of power, or speed at which work is done, usually related to the power of an engine or motor. power is calculated by multiplying force (in pounds) by  speed (in feet per second).

Let H= horsepower, W=watt

As we are given horsepower is directly proportional.

So, the relation is W=kH where k is constant.

Here, H=5 and W=3730.

By substituting the value of W and H we will find the value of k,  we get

3730=k×5

3730/5=k

746=k

Now, substituting the value of k in relation and we get

W=746H

We have to find the power of 2 horsepower.

So, we will substitute H=2 in above relation, we get

W=746×2

W=1492 watts.

Hence, the 2 horsepower is equal to 1492 watts when 5 horsepower is equal to 3730 watts.

fgiga [73]
The correct answer is A) the area is 24 ft^2 and the perimeter is 20 feet

To find the perimeter:
2(6)+2(4)=12+8=20
2(L)+2(W)=perimeter
L=length and W=width

To find the area:
L*W=A
6ft*4ft=24ft^2

Again one question not two
Anettt [7]

Answer: A) 5m = 50; m = 10

Step-by-step explanation:

The diagram shows 5 "m"s, or 5*m equal to 50.  Thus, 5m=50.

Because 5m = 50, divide both sides by 5 to get that m = 10

Please answer all the questions shown in the image below
kompoz [17]

Answer:

A-

  • first x=1 and y=5
  • then x=2 and y=10
  • then x=3 and y=15
  • then x=4 and y=20

YES they are proportional because the answer every time is 5x

B- The x coordinate is growing by one and the y coordinate is growing by 5

C- for 0 t-shirts the y coordinate would be 0 as well, and for 5 shirts it would be 25 (5*5)

Focus on Math-

no it would not because instead of the equation looking like 5x it would look like 5x+4

Enjoy!!
