Answer:

  x = 3

Step-by-step explanation:

Expand the left side and solve the resulting 2-step linear equation.

  x^2 -(4 -4x +x^2) = 8

  x^2 -4 +4x -x^2 = 8 . . . . . eliminate parentheses

  -4 +4x = 8 . . . . . . . . . . . . . collect terms

  -1 +x = 2 . . . . . . divide by 4

  x = 3 . . . . . . . . . add 1

Answer:

[tex]\frac{2}{n+2}[/tex]

Step-by-step explanation:

Given

Let the total probability be 1

Probability that Brian wins a raffle  = n/n+2

Probability that Brian does not win a raffle = 1 - Probability that Brian wins a raffle

Probability that Brian does not win a raffle = 1 - (n/n+2)

Probability that Brian does not win a raffle = [tex]\frac{n+2-n}{n+2}[/tex]

Probability that Brian does not win a raffle = [tex]\frac{2}{n+2}[/tex]

Hence required fraction is  [tex]\frac{2}{n+2}[/tex]

Answer:

D. 38%

Step-by-step explanation:

3/8 as a percentage is 37.5% and that is rounded to 38%! :) 37% is close but it is not rounded making it not the best estimate, therefore it is not correct.

  slope = -1/2

Step-by-step explanation:

For the rise of -1 and the run of 2, the slope is ...

  m = rise/run = -1/2 . . . . slope in simplest form

Additional comments

It usually works best if you can identify points on the graph where the line crosses grid intersections. Then the number of squares in each direction can be counted easily. If you work with two grid intersections that are closest together, then the ratio of rise to run will already be in reduced form.

On this graph, there are other grid crossing points that are 4, 6, 8 units to the right or left of the one where we started. You need to remember that "run" is positive in the "right" direction, and "rise" is positive in the "up" direction.

We have shown the "rise" and "run" lines above the graphed line. They can also be shown below the graphed line.

Here, the grid squares are 1 unit in each direction. You need to pay attention to the scale, because some graphs have different numbering vertically than horizontally. The values for "rise" and "run" need to be figured using the appropriate scale.

Answer:

X and y both equal 94 degrees

Step-by-step explanation:

Suplimentary angles equal 180 degrees so therefore a straight line equals 180 degree and 86 of those degrees are taken up so 180-86=94 and x and y are both the same angles so therefore x and y both equal 94 degrees

Brainiest ?  

Answer:

117 units

Step-by-step explanation:

if you use the ratio of the two longest sides then you can find all side lengths

[tex]\frac{52}{20}[/tex] = [tex]\frac{x}{10}[/tex];    x = half of 52, or 26

[tex]\frac{52}{20}[/tex] = [tex]\frac{x}{15}[/tex];    20x = 52 · 15

              20x = 780

               x = 39

add to get perimeter: 52 + 26 + 39 = 117 units

Perimeter of the larger triangle is 117 units

Given

Two triangles are similar. The smaller triangle has side lengths 10, 20, and 15 units.

When the triangles are similar then the sides are in proportion

the longest side of the smaller triangle is 20 units

The larger triangle's longest side is 52 units.

Lets find out the unknown sides of largest triangle

Let x  and  y be the unknown sides . Make a proportion and solve for x  and y

[tex]\frac{52}{20}=\frac{x}{10} \\x=\frac{52}{20} \codt 10\\x=26\\\\\\\frac{52}{20}=\frac{y}{15}\\y=\frac{52}{20} \codt 15\\y=39[/tex]

The unknown sides of largest triangle is 26 and 39 units

To find out the perimeter add all the sides of largest triangle

Perimeter =[tex]26+39+52=117[/tex]

Perimeter of the larger triangle is 117 units

Answer:

120

Step-by-step explanation:

-140 + 20 = 120

Step-by-step explanation:

Area of triangle = 1/2 (L*h)

let the num be a

/a÷5=20

/a=20×5

/a =100

square root of 100 is 10

so the number is 10

The number that she have to think of should be considered as the 10 when her answer is 20.

Since here we assume the number be a

And, now she have to determine the square root and then divide it by 5

So, it can be like

[tex]a\div 5=20\\\\a=20\times 5[/tex]

a =100

Now the square root of 100 should be 10

hence, a = 10

Therefore, The number that she have to think of should be considered as the 10 when her answer is 20.

Answer:

Step-by-step explanation:

The shortest sides are corresponding in similar triangles

One has side length of 5, another one is 20

Scale factor is:

Since perimeter is sum of 3 sides and each side has 4 times difference, the perimeter will have 4 times the difference. So it is:

Dilation doesn't affect angle measures. A and W are corresponding angles and they measure the same.

m∡W = 5x = 5*5 = 25°

Dilation doesn't affect angle measures. B and M are corresponding angles and they measure the same.

m∡B = 2x + 30 = 2*20 + 30 = 70°

Answer:

B. 47 degrees

Step-by-step explanation:

/_wxy = 56

/_xyw = 68

/_xwy = 180 - (56 + 68) = 56

[interior angles of a triangle =180]

/_wzv = 77

Answer:

52feet

Step-by-step explanation:

The set up will be a right angle

Let the angle of depression be 30°

The height above the sea level will be the opposite

The distance of the ship from the base is x (adjacent)

Using TOA

Tan theta = opposite/adjacent

Tan 30 = 30/x

x = 30/tan 30

x = 30/0.5774

x = 51.96

x ≈ 52 feet to the nearest foot
