Answer:
C. The arc lengths are proportional: Arc C D = 4 arc E F.
Step-by-step explanation:
The question is incomplete. Here is the complete question.
In each circle below, a 50° angle with a vertex at the center of the circle is drawn. How are minor arc lengths CD and EF related?
Circle A and B are shown. Line segments D A and C A are radii with lengths of 8 centimeters. Angle D A C is 50 degrees. Line segments F B and E B are radii with lengths of 2 centimeters. Angle F B E is 50 degrees.
They are the same because the central angle measure is the same.
The arc lengths are proportional: Arc C D = 2 arc E F.
The arc lengths are proportional: Arc C D = 4 arc E F.
The arc lengths are proportional: Arc C D = 6 arc E F.
Using the formula for calculating the length of an arc to find the length of both arcs.
[tex]L = \frac{\theta}{360} * 2\pi r[/tex]
For the minor arc CD:
[tex]\theta = 50^0\\[/tex]
r = 8cm
L = 50/360 * 2π(8)
L = 5/36 * 16π
L = 80π/36
Length of CD = 20π/9 cm²
For the minor arc EF:
[tex]\theta = 50^0\\[/tex]
r = 2cm
L = 50/360 * 2π(2)
L = 5/36 * 4π
L = 20π/36
Length of arc EF = 5π/9 cm²
Find the relationship between both lengths:
From CD = 20π/9 cm²
CD = 4 * (5π/9 cm²)
since length of arc EF = 5π/9 cm²
Then arc CD = 4* arc EF
This shows that the length of arc CD is four times that of arc EF
Five times the smallest of three consecutive odd integers is seven more than twice the largest. Find the largest
integer.
// we also have to se only one variable to solve this equation.
like this x+3 would be okay
Answer: 9
Step-by-step explanation:
Let the consecutive odd numbers be y, y+2 and y+4.
Five times the smallest of three consecutive odd integers is seven more than twice the largest. Find the largest integer can be expressed as:
5y = 2(y+4) + 7
5y = 2y + 8 + 7
5y = 2y + 15
5y - 2y = 15
y = 3
The smallest odd number is 5
The largest integer will be:
= y + 4
= 5+4
= 9

The scale factor from EFGH to ABCD is 2
Answer:
Close, but the answer is 1/2
Step-by-step explanation:
The answer would be 2 when you are finding the scale factor of ABCD to EFGH, but since it is going from EFGH to ABCD, then all you have to do is divide by 2 or multiply by 1/2.
EFGH to ABCD= 12 • 1/2 = 6 or 12 ÷ 2 = 6

A group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the trip. Each small car can hold 5 people and each large car can hold 8 people. A total of 5 cars were rented which can hold 34 people altogether. Determine the number of small cars rented and the number of large cars rented.
Answer:
2 small; 3 large
Step-by-step explanation:
Using s and L for the number of small and large cars, respectively, we have ...
5s +8L = 34 . . . . number of passengers
s + L = 5 . . . . . . . number of cars
5s +8(5 -s) = 34 . . . . substitute for L
-3s +40 = 34
-3s = -6 . . . . . . subtract 40
s = 2 . . . . . . . . divide by -2
L = 5-2 = 3
2 small cars and 3 large cars were rented.

What is |-6,035| ?
Plz help
Answer:
6,035
Step-by-step explanation:
(Forgive me, I'm not awesome at explaining). You are calculating the absolute value. For this you will be ignoring the negative sign if it is in-between the lines. Or, to simply put it, how far away it is from 0 on a number line, you can use a number line to calculate this for smaller numbers but 6,035 is waaaaay too big. So, I just ignore the negative because, for example, you wouldn't say you were -6 miles away from your house, you would say you were 6 miles away. That's kind of what we are doing here. If the negative was OUTSIDE of the lines then it wouldn't be cancelled out. Ex. -|2| it is 2 away from 0, BUT you need to add on the negative making the answer to the -2. I hope this helped I'm not good with explaining!

Answer:
x=1, y=2
Step-by-step explanation:
Answer: x = 13 and y = -2
Step-by-step explanation:
You need to use the elimination method for each equation, so that means being able to cross them out by equaling them to 0. You can choose x value or the y value, since you need to do 2 things to the y value I will show you an easier way with the x value since it is equal to one in the top equation.
Looking at the bottom equation, you need to find a way to set the x equation to cross 2x out making it 0. Removing x from this, how can you make 2 end up being 0? Subtract 2 from it, but x is not -2 on the first equation, so you have to times everything in that equation by -2 to make x -2.
so basically,
-2(x + 3y = 7)
your new equation is
-2x -6y = -14
put your other equation under it to eliminate the x value finally.
-2x -6y = -14
2x + 2y = 6
so you only need to combine like terms. X is no longer included because x is eliminated.
-4y = 8
divide to find the value of y
Y = -2
plug your newly found equation in for y in the original equation (either one is fine.
x + 3(-2) = 7
x -6 = 7
add 6 to both sides
x = 13

Step-by-step explanation:
1. Pilar and her sister Marisol live near the beach. Pilar has 80 seashells in her collection when Marisol started collecting seashells. Marisol started with zero seashells in her collection.
• Pilar adds 10 seashells to her collection each week for x weeks.
• Marisol adds 20 seashells to her collection each week for x weeks.
(a) Write an inequality to represent the situation when the number of seashells in Marisol's collection is greater than the number of seashells in Pilar's collection.
(b) Solve the inequality in part (a) for the x. Show your work and explain your answer.
Answer:
a. 20x > 10x + 80
b. •20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
Step-by-step explanation:
10x + 80 = number of seashells Pilar has.
20x = number of seashells Marisol has.
answer for a: 20x > 10x + 80
answer for b: 20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8

distance between (4, –1) and (8, –1)?
Answer: 4
Step-by-step explanation: compute the distance between (x1, y1), (x2, y2):
(8 -4)² + [ -1 - (-1) ]² = 4
Answer:
4
Step-by-step explanation:
X1 = 4
X2= 8
Y1 = -1
Y2= -1
Distance Formula = √(X2-X1)² + (Y2-y1)²
Step 1. calculate (X2-X1)²
(8 - 4)2 = 16
Step 2. calculate (Y2-Y1)²
(-1 - -1)2 = 0
Step 3. calculate √16 + 0

(a+b)^3+8c^3
Answer:
(a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
Step-by-step explanation:
Given
(a + b)³ + 8c³ ← this is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²)
Thus
(a + b)³ + 8c³
= (a + b)³ + (2c)³
= (a + b + 2c)( (a + b)² - 2c(a + b) + (2c)² )
= (a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
