What is the surface area?

Answer:

x = 3/2 or 1.5.

y = -1/2 or -0.5.

Step-by-step explanation:

Solve for one equation, one variable.

2x + 4y = 1

subtrract 4y from both sides.

2x = 1 - 4y

divide by 2 to get x by itself.

x = 1/2 - 2y

Now that we have this, we can put it into the other equation.

3x - 5y = 7

Substitute variable.

3(1/2 - 2y) - 5y = 7

Distribute the 3.

1.5 - 6y - 5y = 7

Combine terms.

-11y + 1.5 = 7

Subtract by 1.5.

-11y = 5.5

Divide by -11.

y = -1/2, or -0.5.

Now we can find x. Substitute this into the initial equation.

2x + 4y = 1

Substitute variable.

2x + 4(-1/2) = 1

Multiply.

2x + (-2) = 1

Simplify.

2x - 2 = 1

Add 2 to both sides.

2x = 3

Divide by 2.

x = 3/2, or 1.5.

x = 3/2 or 1.5.

y = -1/2 or -0.5.

Answer:

x = 106.5

Step-by-step explanation:

sin 28 = opp/hyp = 50/x

0.4695 = 50/x

0.4695x = 50

x = 106.5

Step-by-step explanation:

inside of a triangle is 180 degrees

[tex]180=90+5x+2+4x-11\\180=5x+4x+90+2-11\\180=9x+81\\180-81=9x+81-81\\99=9x\\99/9=9x/9\\11=x[/tex]

now that we have our x we can find the angles

Answer:

34.8 to 1 dp

Step-by-step explanation:

18/2 = 9

Area of rectangle 18 X 9 = 162 cm^2

diameter of each circle 9

radius = 4.5

Area of a circle = πr^2

π X 4.5^2 = 63.6172512

63.6172512 X 2 (there are 2 circles) = 127.234502

162 - 127.234502 = 34.7654975

34.8 to 1dp

Answer:

Symmetric

Step-by-step explanation:

The dot plot provided is almost symmetric :

Obtaining the median value :

2, 3, 5, 5, 6, 6, 6, 6, 7, 7, 7, 9

1/2 ( n + 1)

n = 12

1/2 (13) = 6.5

(6 + 6) /2

12 /2

= 6

Counting the number of points to the left and to the right of the median vlaue in the plot, we'll see that the difference in values aren't entirely different, and as such folding along the median value won't leave too much on one side than the other. Hence, the plot is symmetric.

Answer:

7:20 A.M.

Step-by-step explanation:

Answer:

X=4

Step-by-step explanation:

3x-2y=8

x+y=6

multiply second equation by 2 so you can eliminate y

2(x+y)=2(6)

2x+2y=12

now add two equations together

first equation:                          3x-2y=8

modified second equation     2x+2y=12

added together eliminates y. 5x+0=20

Answer:

  5.3

Step-by-step explanation:

The Pythagorean theorem applies. The square of the hypotenuse is equal to the sum of the squares of the other two sides.

  8² = x² + 6²

  64 = x² +36

  28 = x²

  √28 = x ≈ 5.3

The missing measure is 5.3.

Comment on the question

The triangle isn't marked, but we must assume it is a right triangle. If it is not a right triangle, we cannot find the missing measure.
