1. A = (1/2)bh = (1/2) * 30 ft * 12 ft = 180 ft^2

2. 21/25 * 100 = 84%

3. $13.26/(3 boxes) = $4.42/box

Digiron [165]

Answer:

d= 8.6 ft

Step-by-step explanation:

In similar triangles, the corresponding sides are in proportion.

\boxed{\dfrac{AW}{MZ}=\dfrac{AJ}{MJ}=\dfrac{WJ}{ZJ}}

To find the value of x,

\dfrac{AJ}{MJ}=\dfrac{WJ}{ZJ}\\\\\\\dfrac{6}{7}=\dfrac{d}{10}\\\\\\\dfrac{6}{7}*10=d

d = 8.6 ft

Alekssandra [29.7K]
Answer: option d. C (0,3), D (0,5).

Justification:

1) The x - coordinates of the vertices A and B are shown in the diagrama, They are both - 4, so the new vertices C and D must be in a line parallel to y = - 4.

2) The y-coordinates of the  vertices A and B are also shown in the diagrama. They  are equal to 3 and 5 respectively.

3) We can see that the new points C and D must be over a parallel line to y = - 4 and that their distance to the points A and B has to be the same distance of the point R and S to U and T.

That distance is 4, so the line may be y = - 7 or y = 0.

4) If the line is y = 7 the points C and D would have coordinates (-7,3) and (-7,5), but this points are not among the options.

5) If the line is y = 0 the points C and D would have coordinates (0, 3) and (0,5), which is precisely the points of the option d. That is the answer.

The function f(x)=g(x), where f(x)=2x-5 and g(x)=x^2-6. The table below shows the process of solving using successive approximat
valkas [14]

Answer:

The positive solution is 2.4.

Step-by-step explanation:

The given functions are

f(x)=2x-5

g(x)=x^2-6

It is given that

f(x)=g(x)

2x-5=x^2-6

0=x^2-6-2x+5

0=x^2-2x-1

The quadratic formula:

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

x=\frac{2\pm \sqrt{(2)^2-4(1)(-1)}}{2(1)}

x=\frac{2\pm \sqrt{8}}{2}

x=\frac{2\pm 2\sqrt{2}}{2}

x=\frac{2(1\pm \sqrt{2})}{2}

x=1\pm \sqrt{2}

x=2.4,-0.4

Therefore the positive solution is 2.4.

LenKa [72]

Answer:

n + 3

Step-by-step explanation:

6 is 3 + 3, 11 is 8 + 3 and 12 is 9 + 3 so the output seems to be the input plus 3. Therefore, when the input is n, the output is n + 3.
