Answer:
s =5*π/2 km
Step-by-step explanation:
arc length s = rθ
where θ =central angle in radians
r = 5km
θ = 90 degrees = 90 degrees/360degrees * 2π = [tex]\frac{1}{4}[/tex](2π) = π/2
s =5*π/2 km

Select all angles that MUST be supplementary to 9
Answer:
Angles supplementary to angle 9 = Angle 10, 7, 5, 1, 4, 3, 15, 12, 24, 22, 20, 19, and angle 16.
Step-by-step explanation:
Use the vertical, and corresponding angles theorem to find congruent angles.
Look for linear pairs (adjacent(next to each other, or share a side) angles that make 180° or a straight angle) from the corresponding angles.
Something is supplementary if it adds to 180 degrees.
The vertical angles theorem states that pairs of opposite angles made by interesecting lines are congruent.
The corresponding angles theorem states that corresponding or angles relative to the same position are congruent if the transversal crosses at least 2 parallel lines.

8 1/4 pounds of flour are used to make 4 1/8 papier-mâché pasta recipe how much flour is used in one recipe
Answer:
1/6
Step-by-step explanation:
ive seen that question b4
2 pounds of flour are required to make 1 recipe, as of the given condition.
Given that
8 1/4 pounds of flour are used to make 4 1/8 paper-mâché pasta recipe how much flour is used in one recipe is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Flour = 8 1/4
Flour = 8.25 pounds
The proportion of the recipe made corresponding to 8.25 pounds of flour = 4.125
Now,
For 1 recipe = 8.25 / 4.125 = 2 pounds of flour are needed.
Thus, 2 pounds of flour are required to make 1 recipe, as of the given condition.

the sum of the interior angles in a pentagon
Answer:
540°
Step-by-step explanation:
When you have a polygon (shape with 3+ sides), you can split the shape into the lowest number of triangles and use that to calculate the interior angles of the shape. Thus works because triangles have angles that always add up to 180°
A Pentagon can be split into 3 triangles minimum, which means you have 180 + 180 + 180. Or...
180 x 3 = 540

Which linear inequality is represented by the graph?
O y > 2x + 2
O yz 2x + 1
Oy> 2x + 1
O y z 2x+2
By analyzing the graph, we will see that the inequality is:
y > 2x + 1
How to know the inequality represented by the graph?
From a first look, we can see two things.
The line is a dashed line, so the values on the line are not solutions.The shaded region is above that line.From that we can conclude that the inequality is something like:
y > line.
To find the equation of the line, we can look at the graph.
We can see that it intercepts the y-axis at y = 1, and for each increase of one unit in the x-axis increases 2 units on the y-axis, so the line is:
2x + 1
Then the inequality is:
y > 2x + 1.

You and your friend are selling magazine subscriptions for a fundraiser. After w weeks, you have sold (3w+8) subscriptions and your friend has sold (6w+6) subscriptions.
Answer:
3w-2
Step-by-step explanation:
Given that, after w weeks you sold (3w+8) subscriptions and your friend sold (6w+6) subscriptions.
So, the difference between the number of subscriptions your friend has sold and you have sold after w weeks = (6w+6)-(3w+8)
=6w+6-3w-8
=3w-2
Hence, the required expression is 3w-2.

please answer
Answer:
a = 6
Step-by-step explanation:
Given that (x - 2) is a factor of P(x) , then P(2) = 0 , that is
P(2) = 2² - 5(2) + a = 0 , so
4 - 10 + a = 0
- 6 + a = 0 ( add 6 to both sides )

A rental car company is running two specials. Customers can pay $50 to rent a compact car
for the first day plus $6 for each additional day, or they can rent the same car for $20 the
first day and $12 for every additional day beyond that. Nora notices that, given the number
of additional days she wants to rent the car for, the two specials are equivalent. How many
additional days does Nora want?
Write a system of equations, graph them, and type the solution
Answer:
After 5 additional days it will be equal
Step-by-step explanation:
1st special: 6x + 50
2nd special: 12x + 20
6x + 50 = 12x + 20
Subtract 20 from both sides;
6x + 30 = 12x
Subtract 6x from both sides;
30 = 6x
Divide both sides by 6;
x = 5
Jim mowed 5/9 of a lawn. Sarah mowed 1/3 of the lawn. What fraction of the lawn remained to be mowed?
Answer:
1/9
Step-by-step explanation:
Because 1/3 is the same as 3/9, 5/9 + 3/9 = 8/9. so then 9/9 - 8/9 = 1/9. Giving them 1/9 of the lawn remained to be mowed.
