Answer:

Question 6 answer is 35

Step-by-step explanation:

using pythagoras theorem, hypotenuse²= opposite²+ adjacent²

since it is said that we're looking for the hypotenuse then the values given are for opposite and adjacent.

therefore, hyp²= 21²+28²

hyp²= 1225 take square root of both sides to eliminate square and find hypotenuse

hyp= 35

Suppose the average yearly salary of an individual whose final degree is a masters is $46 thousand less than twice that of an in
zepelin [54]

Answer:

  • <em><u>average yearly salary of an individual whose final degree is a masters:</u></em><u> $ 66 thousand</u>

<u></u>

  • average yearly salary of an individual whose final degree is a bachelors:<u> $ 56 thousand</u>

Explanation:

You can set a system of equation using the following steps:

1. Name the variables:

  • average yearly salary of an individual whose final degree is a masters: x

  • average yearly salary of an individual whose final degree is a bachelors: y

2. Set the equations that relate the variables:

  • the average yearly salary of an individual whose final degree is a masters is $46 thousand less than twice that of an individual whose final degree is a bachelors:

        equation (1): x = 2y - 46

  • combined, two people with each of these educational attainments earn $122 thousand:

         equation (2): x + y = 122

3. Solve the system:

  • x = 2y - 46 . . . equation (1)
  • x + y = 122 . . . equation (2)

Substitute equation (1) into equation (2)

  • 2y - 46 + y = 122

Solve for y:

  • 3y = 122 + 46
  • 3y = 168
  • y = 168 / 3
  • y = 56 (this means that the average yearly salary with a bachelors degree is $ 56 thousand).

Subsitute the value on y in equation 1, to find the value of x:

  • x = 2y - 46 = 2(56) - 46 = 112 - 46 = 66.

Thus, the average yearly salary of a person with a masters degree is $ 66 thousand.

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.
