Answer 1

Answer:

A) 3/56 + 27/56 = 30/56 ÷ 2/2 = 15/28

Step-by-step explanation:

So, there's 3/56 cities that have a lake and 27/56 cities that have a river.

Since the question is asking how much have a lake or river, we add them up.

3/56 + 27/56 = 30/56

(Divide by 2 since that's the common factor)

30/56 ÷ 2/2 = 15/28

6. How far is it from the point (-5, 7) to the point (6,-2)? Round your answer to the nearest tenth.

Answers

Answer:

14.2 units

Step-by-step explanation:

Here x increases by 11 from -5 to +6.  This is the length of the horizontal leg of a right triangle.  Then y decreases by 9 from 7 to -2.  This is the length of the vertical leg.  The hypotenuse of this triangle may be found using the Pythagorean Theorem:

11^2 + 9^2 = (hypotenuse)^2, or

hypotenuse = √(121 + 81) = √202 ≈ 14.2 units

Answer:

≈ 14.2

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 5, 7) and (x₂, y₂ ) = (6, - 2)

d = [tex]\sqrt{(6+5)^2+(-2-7)^2}[/tex]

  = [tex]\sqrt{11^2+(-9)^2}[/tex]

  = [tex]\sqrt{121+81}[/tex]

  = [tex]\sqrt{202}[/tex]

  ≈ 14.2 ( to the nearest tenth )

-5 = 1/7a

Answers

Answer:

-35

Step-by-step explanation:

[tex]-5 = \frac{1}{7}a\\-35 = a[/tex]

I got this by multiplying the numerator by 7. This allows the denominator to be the same as the numerator, thus equalling 1.

1 * a = a

Answer: a = -35

Step-by-step explanation:

1. -5 = 1/7(a) || GIVEN

2. -5 * (7) = (7) * 1/7(a) || Isolate "a" on one side of the equation by multiplying 7 to the other side.

3. -35 = a

In if GS ⊥ XJ and XJ⊥EA what is true about GS and EA

Answers

Answer:

([tex]GS[/tex]) || ([tex]EA[/tex])

Step-by-step explanation:

When two lines are parallel, all four angles formed by the intersection of the two lines are right angles, meaning their angle measures are (90°). This means that alternate interior angles are congruent because all alternate interior angles measures equal (90°). Therefore, by the alternate interior angles converse theorem, lines ([tex]GS[/tex]) and ([tex]EA[/tex]) are parallel.

The alternate interior angles converse theorem states if two angles are congruent and they have the relation of being a part of two lines intersected by a third line, then the two non-intersecting lines are parallel.

82+2x=180
2x=98
x=49
answer is x=49

X=49°

Step-by-step explanation:

we have an isosceles triangle

thus our equation is

x+x+82=180°

=>2x+82°=180°

cancel 82 from both sides

=>2x=98

divide both sides by 2

therefore

X=49

Answers

Answer:

  C.  25°

Step-by-step explanation:

A useful relation for this geometry is "an exterior angle of a triangle is equal to the sum of the remote interior angles." The measure of arc BC is the same as the measure of central angle BDC, which is an exterior angle of triangle ACD.

__

Triangle ACD has sides AD and CD that are radii of the circle, so it is an isosceles triangle with angle A ≅ angle C. Exterior angle BDC is the sum of those congruent angles:

  ∠BDC = ∠CAD +∠ACD

  50° = 2×∠ACD

  25° = ∠ACD . . . . . . . . divide by 2

PLEASE 100 POINTS Write the polynomial in factored form and explain how you did it.

Answer: f(x)=(x-5)(x+5)(x+2)

Points given: (5,0),(-5,0),(-2,0)
To get the factors do x- the roots above:
Solve for x:
X+5=0 X=-5
X-5=0 X=5
X-2=0 X=2
Now we have (x-5),(x+5),(x+2)

what is the slope of this graph?​

Answer:

Slope = -1

Step-by-step explanation:

Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,

Slope = [tex]\frac{4-2}{1-3}[/tex]

          = (-1)

Therefore, slope of the line is (-1).

On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places

Answers

Answer:

The probability that two of them

die is 0.257

Step-by-step explanation:

From the question, we have that the mortality rate is 0.1

So the probability that they will survive is 1-0.1 = 0.9

Now, we want to check that two will die

We are going you use the Bernoulli approximation of the Binomial theorem as follows

= nCr * p^n * q^(n-r)

where n = 16

r = 2

P = 0.1

q = 0.9

Substituting these values;

14 C 2 * 0.1^2 * 0.9^12

= 0.257

For the polynomial, list each real zero and its multiplicity. Determine whether the graph
crosses or touches the x-axis at each x -intercept.
f(x) = 3(x + 7)(x + 3)^2?
A? B? C? D?

Answers

Answer:

B

Step-by-step explanation:

You find the multiplicity by looking at the power of the original root. You can imagine it as [tex](x+7)^1(x+3)^2[/tex]. Now set those equal to 0 to find the value of them as roots.

[tex]x+7=0\\x+3=0[/tex]

Solve them both and you get:

[tex]x=-7\\x=-3[/tex]

Now as we saw in the origin of the roots above that (x + 7) was raised to the first power. That means it has a multiplicity of one, which also means it crosses when it reaches the x-axis. (x + 3) however had a multiplicity of 2, since it was squared. That means that (x + 3) will touch and turn the x-axis.

Therefore the answer is B since that agrees with everything we said.
