Answer:

Decimal=0.76 proportion=76%

Step-by-step explanation:

19/25 let's find the decimal first

long division:

25|19

25 goes into 1, 0 times so;

    0

25|19

   -0

     19

25 goes into 19 0 times so;

    00.

25|19.0

   -0

     19

     -0

     190

25 goes into 190 7 times so;

    00.7

25|19.00

   -0

     19

     -0

     190

    -175

       150

25 goes into 150  6 times so;

    00.76

25|19.00

   -0

     19

     -0

     190

    -175

       150

      -150

           0

now 19/25 as a proportion;

19........x

---- = ------

25.....100

25*4=100 so 19*4=x

19*4=76 so x = 76

and 76/100=76%

Surface Area of the figure is 1208 square centimeters
a=20
b=13
c=12
d=5
e=8
Top face:
A1=a×e=20×8
ae=160
Bottom face:
A2(a+2d)×e=(20+2×5)×8=(20+10)×8=30×8
(a+2d)e=240
Front face:
Rectangle
a×c=20×12=240
Triangle:
12c×d=12×12×5=6×5=30
A3Rectangle +2 triangles
240+2×30=240+60=300
(a+d)c=300
Slant face:
A4=b×e=13×8=104
be=104
Total surface area
A=A1+A2+2(A3+A4)
A1=160
A2=240
A3=300
A4=104
Thus,
A=160+240+2(300+104)
A=400+2(404)
A=400+808=1208
Surface Area of the figure is 1208 square centimeters

What is the solution to the system of equations? (7, 9) (9, 7) (–5, 11) (11, –5)
KIM [24]

Answer: (7, 9)

Step-by-step explanation: To solve this system, I would use addition.

To solve a system of equations by addition,

we need one of our variables to cancel out.

Notice that we have a 4x in our first equation.

If we had a -4x in our second equation, the x's would cancel.

To create a -4x in the second equation,

we must multiply the entire equation by -4.

So we have (-4)(x + 6y) = (61)(-4).

Rewriting this equation, we have -4x - 24y = -244.

Now let's rewrite both equations.

<h2>4x - 5y = -17</h2><h2>-4x - 24y = -244</h2><h2>_____________</h2><h2 />

Now when we add the equations together, the x's cancel.

So we're left with -29y = -261.

Now divide both sides by -29 and we have y = 9.

To find x, we plug a y back in for x in either equation.

So let's go with our second equation, x + 6y = 61.

Plugging a 9 in for y, we have x + 6(9) = 61 or x + 54 = 61.

Subtracting 54 from both sides, we have x = 7.

So x = 7 and y = 9 which we can write as the ordered pair (7, 9).
