Find the area of the triangle.<br> 3 cm<br> 11 cm<br> C с<br> 14.5 cm
boyakko [2]

Answer: The answer is 43.5 because when using the formula you get this result.

Step-by-step explanation: Area of triangle is base x height divided by 2. So do our base 14.5 and our height 6 and multiply them together. 14.5 x 6 = 87 / 2 = 43.5

PLEASE ANSWER AS QUICK AS POSSIBLE
Lady_Fox [76]

Answer:

  (a)  h^-1(x) = (x+6)/6

Step-by-step explanation:

The inverse relation can be found by solving for y: x = h(y).

<h3>Solution</h3>

  x = h(y) . . . . . the inverse relation

  x = 6y -6 . . . . . use the function definition

  x +6 = 6y . . . . add 6

  (x +6)/6 = y . . . . divide by 6

The inverse function is ...

  \boxed{h^{-1}(x)=\dfrac{x+6}{6}}

I’m stuck, please give the explanation for the first question.

----------------------------------------------
Define x:
----------------------------------------------
Let x be the number of students in the second class:
⇒second class = x

There are 3 more students in the first class than in the second class:
⇒first class = x + 3

There are 2 more students in the third class than in the second class:
⇒third class = x + 2

----------------------------------------------
Expression for each class:
----------------------------------------------
First class = x + 3
Second class = x
Third class = x + 2

----------------------------------------------
Expression for total number of students:
----------------------------------------------
Total = x + 3 + x + x + 2
Total =  3x + 5

----------------------------------------------
Find x:
----------------------------------------------
There are 80 students in total, so
3x + 5 = 80
3x = 75
x = 25

----------------------------------------------
Find the number of students in each class:
----------------------------------------------
First class = x + 3 = 25 + 3 = 28
Second class = x = 25
Third class = x + 2 = 25 + 2 = 27

--------------------------------------------------------------------------------------------
Answer: There are 25 students in the second class.
--------------------------------------------------------------------------------------------
