PLZ HELP 50 POINTS AND BRAINLIEST!!!!!!!! Karen has a large pile of colored rods. Each color is a different length. She is trying to connect different colored rods to make triangles as part of a hanging sculpture. Here is a list of rod lengths.
Red: 3 inches
Orange: 4 inches
Yellow: 5 inches
Green: 7 inches
Blue: 9 inches
Purple: 12 inches
1. How many triangles can she make with them if each side is a different color? List the combinations that work.
2. Karen was just trying different combinations of colored rods one at a time, placing the colored rods together to see if they make a triangle. What method did you use to determine the triangle options? Which method do you think is better and why?
Answer:
9 possible combinations: RGB, RYG, RGB, OYG, OGB, OBP, YGB, YBP, GBP
Step-by-step explanation:
We need to consider The Triangle Inequality Theorem which states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.Let's see what are the possible combinations:
3+4= 7 so possible 3rd side is 5
3, 4, 5 or ROY3+5= 8 so possible 3 rd side is 7
3, 5, 7 or RYG3+7= 10 so possible 3rd side is 5 or 9 (5 is repeat of the one above)
3, 7, 9 or RGB3+9= 12 so possible 3rd side is 7, see one above
3+12= 15 so possible 3 rd side is none
4+5=9 so possible 3rd side is 7
4, 5, 7 or OYG4+7= 11 so possible 3rd side is 9
4, 7, 9 or OGB4+9= 13 so possible 3rd side is 12
4, 9, 12 or OBP5+7= 12 so possible 3rd side is 9
5, 7, 9 or YGB5+9= 14 so possible 3rd side is 12
5, 9, 12 or YBP7+9= 16 so possible 3rd side is 12
7, 9, 12 or GBPSo the possible 9 combinations are:
RGB, RYG, RGB, OYG, OGB, OBP, YGB, YBP, GBP

Answer:
x = 3
y = 1
Step-by-step explanation:
9x - y = 26 ---------------(I)
9x + y = 28 ---------------(II)
9x - y = 26
9x = 26 + y
Substitute 9x = 26 + y in equation (II)
26 + y + y = 28 {add like terms}
26 + 2y = 28 {subtract 26 from both sides}
2y = 28 - 26
2y = 2 {divide both sides by 2}
y = 2/2
y = 1
Substitute y =1 in equation (I)
9x - 1 = 26
9x = 26 + 1
9x = 27
x = 27/9
x = 3
x = 3
y = 1

A parking garage allows users to park the first hour free and then charges $2.50 for each additional hour or fraction of an hour. Which equation represents this situation?
Answer:
An equation that could be used to represent this equation is:
y = 2.5x - 2.5
Step-by-step explanation:
x = number of hours
y = the amount that the user has to pay
You have to multiply the number of hours by $2.50. Then subtract $2.50 from that amount for the first hour that is the parking garage allows the user to park for free.
Answer:
f(x)=2.50[x-1]

"Ashley and Beth drove from city A to city B in exactly 5 hours, not taking any rest stops. Ashley drive up to the area located half way between the two cities at the average speed of 40 miles per hour and then Beth drove the other half at an average speed of 60 miles per hour. How many hours did Beth drive on their trip?"
Answer:
Time taken by Beth = 2 hours
Step-by-step explanation:
Given:
Average speed of Ashley = 40 miles per hour
Average speed of Beth = 60 miles per hour
Total time taken = 5 hours
Distance covered by Ashley = Distance covered by Beth
Find:
Total time taken by Beth
Computation:
Assume, Distance covered by Beth = x
So, Distance covered by Ashley = x
Time taken by Beth = t
Time taken by Ashley = 5 - t
So,
Distance covered by Ashley = Average speed of Ashley × Time taken by Ashley
x = 40 × (5 - t)
x = 200 - 40t................Eq1
Distance covered by Beth = Average speed of Beth × Time taken by Beth
x = 60 × t................Eq2
From Eq2 - Eq1
100 t = 200
t = 2 hours
Time taken by Beth = 2 hours

Answer:
<B = 108 degrees
Step-by-step explanation:
<A = <B (Alternate Angles are congruent)
So,
6x+18 = x+93
=> 6x-x = 93-18
=> 5x = 75
Dividing both sides by 5
=> x = 15
Now,
<B = x+93
=> <B = 15+93
=> <B = 108 degrees

Given that tan θ = –8∕15 and θ is in quadrant IV, find sin θ. Question 19 options: A) 15∕17 B) –15∕17 C) –8∕17 D) 8∕17
Answer: C
Step-by-step explanation:
In the quadrant IV, it is only a cos θ that is positive.
Given that tan θ = –8∕15
Where tan θ = opposite ÷ adjacent
Where opposite = 8 and adjacent = 15
We can find the hypothenus by using pythagorean theorem
Hypothenus = sqrt(15^2 + 8^2)
Hypothenus = sqrt(289)
Hypothenus = 17.
Sin θ = opposite ÷ hypothenus
Sin θ = 8/17
Since Sin θ is also negative in the fourth quadrant, therefore
Sin θ = - 8/17
Option C is correct.
plz help find the equation of the circle
Answer:
[tex](x-2)^2+(y+4)^2=34[/tex]
Step-by-step explanation:
The standard form for the equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex], where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius. Since you already know the coordinates of the center of the circle, all you need to do is find the radius. Using the distance formula:
[tex]r=\sqrt{(7-2)^2+(-1-(-4))^2}=\sqrt{5^2+3^2}=\sqrt{25+9}=\sqrt{34}[/tex]
The equation of the circle is therefore:
[tex](x-2)^2+(y+4)^2=34[/tex]

John goes running every morning. He can run 3 miles in 1 hour. How many miles would he be able to run in 1 and ½ hours? A. 4.5 miles B. 2 miles C. 6 miles D. 10 miles
Answer:
2
Step-by-step explanation:
well less than 3
Answer:
A
Step-by-step explanation:
The easiest way to do this problem is to find out how far he can go in 1/2 hour.
If he goes 3 miles in 1 hour
he will go 3/2 miles in 1/2 hour
=============
Now just add this onto the distance travelled in 1 hour.
3 + 3/2 = 3 + 1.5 = 4.5
The answer is A
The answer can be obtained another (perhaps better ) way.
Set up a proportion
1 hour gives 3 miles
1.5 hours gives x
1/1.5 = 3/x Cross multiply
1*x = 1.5 * 3 Combine
x = 4.5 miles

Is the value of 9−y twice as much as the value of y?
Answer:
I think it is greater because when you put the y alone it has the value of 1.
So, 9-y it will always be greater. It can be double and triple as well. I hope this helps you.
