The values of r and w will be 50 and 140 degrees.

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

From the Exterior Angle of a Triangle Property;

38° + 103° = w

w = 140°

Let x be the exterior angle so that

x = r + 90°

Similarly,

By vertically opposite angle;

w = x

So, x = r + 90°

140 = r + 90°

r = 140 - 90

r = 50

Hence, the values of r and w will be 50 and 140 degrees.

Step-by-step explanation:

 is the answer to the question.  

To understand these questions, first look at the way the answers are written out.

Alia questions three students from her class, that might be an answer, but she didn't randomly pick them.

Miles randomly surveys a group of customers at a coffee shop, that might be one, but he might have surveyed a 25 year old instead of a 24 year old, so thats not one.  

Carson interviews students working part-time to gather data, he didn't select random students, he interviewed all of them, so that is not a valid option.

 Lea speaks with the managers at half of the town's 10 supermarkets, which stock similar items, to find out which breakfast cereal is most popular among the town's residents, that one is not stating that she interviewed, but she interviewed half of the 10, which is five, which can be selected randomly.  

So the correct answer is D.

9 is the square root of 81

Answer:

x = 7/3

Step-by-step explanation:

Given equation:

To determine the value of "x", we need to isolate the x-variable and it's coefficient on one side of the equation. This can be done by subtracting 49 to both sides of the equation.

We can see that the negative sign in on both sides of the equation. Remove it by dividing -1 to both sides of the equation.

Clearly, we can see that 9x² and 49 are perfect squares. Therefore,

Take square root both sides of the equation:

To determine the value of "x", we need to isolate it "completely". This can be done by dividing 3 to both sides of the equation

Therefore, the value of "x" must be 7/3.

Answer:

x = 7∕3, –7∕3

Step-by-step explanation:

To find the solutions of the quadratic equation -9x^2 + 49 = 0, we can solve for x by isolating x^2 first:

-9x^2 + 49 = 0

-9x^2 = -49

Dividing both sides by -9, we get:

x^2 = 49/9

Taking the square root of both sides, we get:

x = ± 7/3

Therefore, the solutions of the quadratic equation -9x^2 + 49 = 0 are x = 7/3 and x = -7/3.

Answer:

5/3 hours ( answer in fraction )

1.66 hours ( answer in decimal )

Step-by-step explanation:

Given,

Distance ( d ) = 15 kilometer ( 15 km )

Velocity ( v ) = 9 kilometers per hour ( 9 km / h )

To find : Time ( t )

Formula : -

v = d / t

t = d / v

= 15 / 9

t = 5/3 hours

Answer: 1 28/100 or 1 7/25

Step-by-step explanation:

The number rounded to the nearest ten will be 1640. The number is grater than the 5 on the scale.

If the digit in the units place is between 0  and 10 i.e., 5, then the unit digit is substituted by 0.

If the digit in the units place is between 5 and 9, that is, > or 5 but less than 10, the units place is replaced by '0,' and the tens place is incremented by 1.

The given number is;

x=1637.984

The number is 7.9 grater than 5. So that the number is rounded to the nearest whole number,i.e.1640

Answer:

S₁₃ = 455

Step-by-step explanation:

the sum to n terms of an arithmetic is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

We require to find both a₁ and d

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

given a₄ = 20 and a₁₃ = 65 , then

a₁ + 3d = 20 → (1)

a₁ + 12d = 65 → (2)

subtract (1) from (2) term by term to eliminate a₁

9d = 45 ( divide both sides by 9 )

d = 5

substitute d = 5 into (1) and solve for a₁

a₁ + 3(5) = 20

a₁ + 15 = 20 ( subtract 15 from both sides )

a₁ = 5

Then

S₁₃ = [tex]\frac{13}{2}[/tex] [ (2 × 5 ) + (12 × 5 ) }

     = 6.5 (10 + 60)

     = 6.5 × 70

The diameter length is 30.

We know that the general equation for a circle is(x−h)²+(y−k)²=r²,

where ( h, k ) is the center and r is the radius.

As we know form of a circle.

We will use this form to determine the diameter of the circle.

(x−h)²+(y−k)²=r²

Given equation is :

(x-7)²+(y-2)²=225

(x-7)²+(y-2)²=(15)²

On comparing the above equation with the with equation of circle, we have

r²=(15)²

r=15

So, the diameter will be the twice the radius.

Step-by-step explanation:

For independent events A and B,

P(B | A) = P(B)

P(A | B) = P(A)

P(A ∩ B) = P(A)P(B)

If P(A) = x   and   P(B) = y  then:

⇒ P(B | A) = y

⇒ P(A | B) = x

⇒ P(A ∩ B) = xy

The sum of the arithmetic series with the parameters  t1 = -2, t3 = 7, and n = 15 is 442.5

The given parameters are:

t1 = -2

t3 = 7

n = 15

Start by calculating the common difference using:

Tn = t1 + (n- 1)d

So, we have:

7 = -2 + (3 - 1) * d

Evaluate

7 = -2 + 2d

Add 2 to both sides

2d = 9

Divide by 2

d = 4.5

The sum  is then calculated using:

[tex]S_n = \frac n2 * (2a + (n - 1) * d)[/tex]

So, we have:

[tex]S_{15} = \frac {15}2 * (2*-2 + (15 - 1) * 4.5)[/tex]

Evaluate

[tex]S_{15} = 442.5[/tex]
