The height of a triangle is half the length of its base. The area of the triangle is 12.25cm. Find the height
pentagon [3]
Answer:  The height of the triangle is:  " 3.5 cm " .
_______________________________________________________
<u>
Note</u>:
 The formula/equation for the area, "A" , of a triangle is:

           A = (1/2) * b * h  ;  or write as:  A = (b * h) / 2 ; 
_________________________________________________
 in which:   "A = area of the triangle" ; 
                  "b = base length" ; 
                  "h = "[perpendicular] height" ; 
_________________________________________________
     Given:  h = (b/2) ;
                  A = 12.25 cm²
{Note:  Let us assume that the given area was "12.25 cm² " .}. 
_________________________________________________
 We are to find the height, "h" ; 

The formula for the Area, "A", is:   A = (b * h) / 2 ; 

Let us rearrange the formula ;
 to isolate the "h" (height) on one side of the equation; 

→ Multiply EACH side of the equation by "2" ; to eliminate the "fraction" ; 

2*A = [ (b * h) / 2 ] * 2 ; 

   to get:   " 2A = b * h " ; 

↔    " b * h = 2A " ; 

Divide EACH SIDE of the equation by "b" ; to isolate "h" on one side of the equation: 

        →  (b * h) / b  = (2A) / b ; 

to get: 
  
        →   h  =  2A / b ; 

Since  "h = b/2" ; subtitute "b/2" for "h" ; 
 
Plug in:  "12.25 cm² " for "A" ;

       →  b/2  =  2A/b ;   →  Note:  " 2A/b = [2* (12.25 cm²) ] / b " ;

Note:  " 2* (12.25 cm²) = 24.5 cm² ; 

Rewrite as: 

       →  b/2  =  (24.5 cm²) / b ;
_____________________________________
Cross-multiply:   b*b = (24.5 cm²) *2 ; 

to get:   b² = 49 cm² ; 

Take the "positive square root" of each side of the equation" ; 
            to isolate "b" on one side of the equation ; & to solve for "b" ; 

             →  +√(b²)  =  +√(49 cm²) ; 

             →  b = 7 cm ; 

Now, we want to solve for "h" (the height) :
_________________________________________________________
             →  h = b / 2 = 7 cm / 2 = 3.5 cm ;

Answer:  The height of the triangle is:  " 3.5 cm <span>" .

The ratios of the measure of the sides of a triangle is 4:10:7. Find the length of each side of the perimeter of the triangle is
dangina [55]

The given ratio of the sides of the triangles is 4:10:7. Let the sides be 4x, 10x and 7x .

And given perimeter is 252 meters .

Perimeter is the sum of all sides. So we get

4x+10x+7x=252 \\ 21x = 252

Dividing both sides by 21

x = 12

So the sides are

4*12=48 meters \\ 10*12=120 meters \\ 7*12= 84 meters

CALCULAR O PERÍMETRO DE UM RETANGULO, SABENDO-SE QUE SUA BASE E ALTURA DIFEREM 12 M E QUE ESTA É 1/3 DAQUELA
Ostrovityanka [42]

perimeter =48

18+18+6+6=48

x-12=x/3

Multiply both sides by 3

3x-36=x

3x=x+36

2x=36

x=18

18-12=18/3

6=6

One side 18 another side 6

At age 40 you deposit $150 at the end of each month into an IRA that pays 4% interest compounded monthly. At age 65, what will t
Svetlanka [38]

Answer:

Annuity= 242.4

Step-by-step explanation:

This is a compound interest problem.

The total amount at the end of 25 years will be

A = p(1+r/n)^(nt)

A = 150(1+(0.04/(25*12)))^ ((25*12)(25))

A= 150(1 + 0.04/300)^ (300*12)

A = 150(1+ 0.0001333)^ 3600

A = 150(1.0001333)^ 3600

A = 1500(1.615828808)

A= 242.374

A= 242.4 to the nearest cent
