How do I alive that problem
Svetach [21]
This can be written as...
(1/2)/(1/4) = h/1

Then you solve all of the fractions by multiplying them by 4 to make them intergers;

4(1/2)/4(1/4) = 2/1 = h/1

This means h is equal to 2.

Hope this helps! :)

Find the value of x for the right triangle. Round your answer to the nearest hundredth
Anna007 [38]

Answer:38.56

Step-by-step explanation:

tan35=opposite ➗ adjacent

0.7002=27 ➗ x

Cross multiplying we get

0.7002(x)=27

Divide both sides by 0.7002

0.7002x ➗ 0.7002=27 ➗ 0.7002

x=38.56041131

x=38.56 nearest hundredth

Dante is a software salesman. Let represent his total pay (in dollars). Let represent the number of copies of History is Fun he
valentina_108 [34]

Considering the given linear function, we have that:

  • The change for each copy that he sells is of $120.
  • If he sells no copies, he makes $2400.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

His payment for x copies bought is:

y = 120x + 2400.

Hence:

  • The change for each copy that he sells is of $120, as the slope is of $120.
  • If he sells no copies, he makes $2400, which is the y-intercept.
