The values of r and w will be 50 and 140 degrees.
What is the Exterior Angle of a Triangle Property?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.

What is 1637,984 rounded to the nearest ten
The number rounded to the nearest ten will be 1640. The number is grater than the 5 on the scale.
What are rule for finding a number rounded to the nearest ten?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;

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.

Velocity ( v ) = 9 kilometers per hour ( 9 km / h )
To find : Time ( t )
Formula : -
v = d / t
t = d / v

Solutions of a quadratic function
From the question, we are to determine the number of real solutions the quadratic function has.
NOTE:
If the graph of the quadratic function crosses the x-axis at two points then we have two solutions. If the graph touches the x-axis at one point then we have one solution.If the graph does not intersect with the x-axis then the equation has no real solution.From the given diagram, the graph of the quadratic function crosses the x-axis at two distinct points.
∴ The quadratic function has two real solutions
The solutions of a quadratic function are the points where the graph intersects with the x-axis.
In the given graph, the solutions to the function are x = -2 and x = 0

The sum of an arithmetic series where t1 = -2, t3 = 7, and n = 15 is
The sum of the arithmetic series with the parameters t1 = -2, t3 = 7, and n = 15 is 442.5
How to determine the sum of the series?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

The fourth term of an arithmetic sequence is 20, and the 13th term is 65. Find the sum of the first 13 terms
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

Find the solutions of the quadratic equation –9x2 + 49 = 0.
Answer:
x = 7/3
Step-by-step explanation:
Given equation:
–9x² + 49 = 0To 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.
⇒ –9x² + 49 - 49 = 0 - 49⇒ –9x² = -49We can see that the negative sign in on both sides of the equation. Remove it by dividing -1 to both sides of the equation.
⇒ –9x² = -49⇒ -9x²/-1 = -49/-1⇒ 9x² = 49Clearly, we can see that 9x² and 49 are perfect squares. Therefore,
⇒ 9x² = 49⇒ (3x)² = (7)²Take square root both sides of the equation:
⇒ √(3x)² = √(7)²⇒ 3x = 7To determine the value of "x", we need to isolate it "completely". This can be done by dividing 3 to both sides of the equation
⇒ 3x/3 = 7/3⇒ x = 7/3Therefore, 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.
