Answer:

Missing Information.

Answer:

A. 28

Step-by-step explanation:

A. 28

step 1.

We know that the diameter of the circle inscribed within the triangle is 28 miles, and we know that E is the incenter of triangle ABC.

step 2.

Next, we learned that the perpendicular legs from the incenter to the sides of the triangle are congruent, and we know that the radius of a circle is 1/2 of the diameter of the circle.

step 3.

Since the diameter of the circle is 28, we know the distance of segment DE is 14. Next, we know the perpendicular legs are equal to segment DE. Thus, we can solve for the amount of additional miles of road by writing 14 + 14 = 28.

The multiplication result to 2/15 and division result to 2/3.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

1/ 3 × 2 /5

Now, to multiply we have multiply numerator and denominator.

1/ 3 × 2 /5

=(1  x 2)/ ( 3 x 5)

= 2 /15

Now, 2/ 5 ÷ 3/ 5

We have to divide the fraction.

Fraction does not support division.

So,2/ 5 ÷ 3/ 5

= 2/5 x 5/3

= 2/3.

Answer:

7.9835

Step-by-step explanation:

Given that :

Mean snowfall per storm (µ) = 4.2 inches standard deviation (s) = 2.3 inches

Only the top 5% of storm should result in school being canceled :

Cut off snowfall for school to be canceled '

P(Z ≥ 5%) ; p(Z ≥ 0.05) = 1.645

Using the z relation :

Z = (x - m) / s

1.645 = (x - 4.2) /2.3

x - 4.2 = 2.3 * 1.645

x - 4.2 = 3.7835

x = 3.7835 + 4.2

x = 7.9835

Cut off snowfall for school to be canceled 7.9835

Step-by-step explanation:

8.50x156,6=1330,25

Answer:

x = 55°

y = 70°

z = 125°

Step-by-step explanation:

Based on the Isosceles triangle theorem, since two sides of the triangle are congruent, therefore, the angles opposite to each of the equal sides are congruent.

Thus:

x = 180° - 125° (angles on a straight line/linear pair)

x = 55°

If x = 55°, the other base angle will also be 55°.

Therefore,

y = 180° - (55° + 55°) (sum of ∆)

y = 70°.

z = x + y (exterior angle of a ∆ theorem)

z = 55° + 70° (substitution)

z = 125°

Equation x = 1 represents the vertical line passing through (1 ,-9).

" Equation of a line is defined as an algebraic expression which is represented by linear equation in two variables with highest degree 1. Minimum two coordinates required to draw a line."

According to the question,

Coordinates in the plane represented by (x, y)

We have

Line passing through the point  = (1 ,-9)

x = 1 for different values of y represents a line perpendicular to x-axis.

Therefore,

Vertical line passing through (1, -9) is equals x = 1.

In △ABC is a right angle triangle.

AC is 6 units longer than side BC.

[tex]Hypotenuse=2\sqrt{17}[/tex]

To find:

The length of AC.

Solution:

Let the length of BC be x.

So, Length of AC = x+6

According to the Pythagoras theorem, in a right angle triangle

[tex]Hypotenuse^2=Base^2+Perpendicualar^2[/tex]

△ABC is a right angle triangle and AC is hypotenuse, so

[tex](2\sqrt{17})^2=(x)^2+(x+6)^2[/tex]

[tex]68=x^2+x^2+12x+36[/tex]            [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]

Subtract 68 from both sides.

[tex]0=2x^2+12x+36-68[/tex]

[tex]0=2x^2+12x-32[/tex]

[tex]0=2(x^2+6x-16)[/tex]

Divide both sides by 2.

[tex]x^2+6x-16=0[/tex]

Splitting the middle term, we get

[tex]x^2+8x-2x-16=0[/tex]

[tex]x(x+8)-2(x+8)=0[/tex]

[tex](x+8)(x-2)=0[/tex]

[tex]x=-8,2[/tex]

Side cannot be negative, so x=2 only.

Now,

[tex]AC=x+6[/tex]

[tex]AC=2+6[/tex]

[tex]AC=8[/tex]

Therefore, the length of AC is 8 units.

Answer:34.17601498.

Step-by-step explanation:

Newton's method of approximation is used to approximate values.

The value of [tex]\mathbf{4\sqrt{73}}[/tex] is 34.17601498

Let the number be x.

So, we have:

[tex]\mathbf{x = 4\sqrt{73}}[/tex]

Square both sides

[tex]\mathbf{x^2 = 1168}[/tex]

Subtract 1168 from both sides

[tex]\mathbf{x^2 - 1168 = 0}[/tex]

Express as a function

[tex]\mathbf{f(x) = x^2 - 1168 }[/tex]

Set x1 to 73/2.

So, we have:

[tex]\mathbf{x_1 = \frac{73}{2} = 36.5}[/tex]

Where:

[tex]\mathbf{x_{n+1} = x_n- \frac{x_n^2-1168}{2x_n}}[/tex]

So, we have:

[tex]\mathbf{x_{1+1} = x_1- \frac{x_1^2-1168}{2x_1}}[/tex]

[tex]\mathbf{x_{2} = x_1- \frac{x_1^2-1168}{2x_1}}[/tex]

This gives

[tex]\mathbf{x_{2} = 36.5- \frac{36.5^2-1168}{2 \times 36.5}}[/tex]

[tex]\mathbf{x_{2} = 34.25}[/tex]

[tex]\mathbf{x_{3} = x_2- \frac{x_2^2-1168}{2x_2}}[/tex]

[tex]\mathbf{x_{3} = 34.25- \frac{34.25^2-1168}{2 \times 34.25}}[/tex]

[tex]\mathbf{x_{3} = 34.1760948905}[/tex]

[tex]\mathbf{x_{4} = x_3- \frac{x_3^2-1168}{2x_3}}[/tex]

[tex]\mathbf{x_{4} = 34.1760948905- \frac{34.1760948905^2-1168}{2\times 34.1760948905}}[/tex]

[tex]\mathbf{x_{4} = 34.1760149814}[/tex]

[tex]\mathbf{x_{5} = x_4- \frac{x_4^2-1168}{2x_4}}[/tex]

[tex]\mathbf{x_{5} = 34.1760149814- \frac{34.1760149814^2-1168}{2\times 34.1760149814}}[/tex]

[tex]\mathbf{x_{5} = 34.1760149813}[/tex]

The values of x4 and x5 are the same up till the 8th decimal place.

Hence, the value of [tex]\mathbf{4\sqrt{73}}[/tex] is 34.17601498

Each side is 6 units.

Step-by-step explanation:

The problem is not how to do the question. The problem is how to get your calculator to do the question.

V = s^3

s = ?

V = 216

So what you need is the cube root of 216

s^3 = 216

cube root(s^3) = cube root(216)

s = cube root 216

Your calculator should have a y^x or x ^y key.

Put in 216

Press the y^x key or the x^y key

Put in 0.33333333333

You should get something like 5.999999 which you should round to 6.

Answer:

There are 2 given situations:

Plant A and Plant B growing in 3 weeks. Find which plant grows proportional

Plant A

=> 1st week = 18 inches

=> 2nd week = 36 inches

=> 3rd week = 56 inches

=> 18 + 18 = 36 + 20 = 56

Thus, this is not proportional

Plant B

=> 1st week = 18 inches

=> 2nd week = 36 inches

=> 3rd week  = 54 inches

=> 18 + 18 = 36 + 18 = 54 inches

thus, the growth of this plant is proportional

Answer:

Since the slope of KM and ST are different, they are not parallel

Step-by-step explanation:

Slope of line KM = [tex]\frac{5}{8}[/tex]

 Slope of ST = [tex]-\frac{8}{5}[/tex]

Determine whether the lines are perpendicular;

Solution:

We can use the slope of a line to determine whether they are perpendicular or parallel to one another.

Parallel lines do not meet one another

Perpendicular lines cross one another at an angle of 90°

Two lines are parallel if their slopes are the same;

  Since the slope of KM and ST are different, they are not parallel
