verify that the segment lengths form a triangle. is the triangle acute, right, or obtuse?
bc Answer: They form an obtuse triangle
Step-by-step explanation:
the length of one side must be greater than the difference and less than the sum of the lengths of the other two sides. In this case the third side must be greater than 3 and less than 31. 3(squareroot) 55 is 22.25 so it fits.

Find a polynomial that represents the surface area of a sphere with a radius of (3x – 5) cm.
The surface area of a sphere is 4π^2. Leave your answer in terms of it.
Answer:
π(36x^2 - 120x + 100)
Step-by-step explanation:
4π(3x - 5)^2 = 4π[(3x)^2 - 2*3x*5 + 5^2] = 4π(9x^2 - 30x + 25)
= π(36x^2 - 120x + 100)

Angle STV is a straight angle. The measure of WTV angle is 40. The measure of STW angle is x . What is the value of x?
Answer: 140
Step-by-step explanation:
We know that the angle measures must add to 180 deg, so:
40 + x = 180
x = 140.

Answer:
s = 71
j = 23
71 = 3j+2
71 - 2 = 3j
39 = 3j
j = 23
Answer:
j=23
s=71
Step-by-step explanation:
Here we have two parallel lines lines( UB and DK).
And we have another line, called a transversal that intersects( crosses) both parallel line. Doing so creates the following angles,
Vertical Angles, Angles are equal in measure Alternate Exterior Angles, Angles are equalAlternate Interior Angles. Angles are equalConsective Angles. Angles are equalLinear Pair Angles. Angles add up to 180So now we look at the graph
First, we know that 3j+2 and s are vertical angles since they are across of each other. So they are equal to each other so let look at another angle first.
3j+s and 71 are Alternate Interior Angles since they lie inside the transversal and are across from each other.
Since they are Alternate Interior Angles, they are equal.
So we set them equal to each other.
[tex]3j + 2 = 71[/tex]
Subtract 2 from both sides
[tex]3j = 69[/tex]
Divide both sides by 3
[tex]j = 23[/tex]
The value of j is 23.
Know to find S, we know s is equal to 3j+2, which when we plug in 23 for j, we get 71.
So s=71

19. A bird flies at 12 miles/hour. How long does he take to fly 36 miles?
Answer:
He flew for 3 hours
Step-by-step explanation:
in this question we can use the formula :
[tex] \boxed{t = \frac{s}{v}} [/tex]
t is time
s is distance
v is Speed
_________________
We know that :
v = 12 miles/hour
s = 36 miles
So :
[tex] t = \frac{s}{v} = \frac{36}{12} [/tex]
[tex] \boxed{t = 3 \: hours}[/tex]

What is the lcm of 12 and 18
Answer:
36
Step-by-step explanation:
Hi there!
We want to find the least common multiple (LCM) of 12 and 18
One easy way to do that is to split up the numbers into one of their factor pairs, find the factor pairs between the numbers we just split apart, and then keep on going, until we only get prime numbers (numbers that only have 1 and itself as multiples)
Let's start with 12.
There are multiple ways to multiply to get to 12, but we can use 3 and 4 for example
12= 3*4
4 is 2 * 2
Substituting 2*2 for 4, 12 is equal to 2*2*3
Now for 18.
18 can also be split up multiple ways; one way would be 9 and 2
18 = 2*9
9 is 3*3
Substitute 3*3 for 9.
18=2*3*3
Now look at 2*2*3; 2 shows up twice in that string of numbers
In 2*3*3, 3 shows up twice in that string of numbers
We multiply the numbers based off of the highest number of times that they occur
In other words, we will multiply 2 * 2 and 3 * 3 together
2 * 2 * 3 * 3 = 4 * 9 = 36
The LCM of 12 and 18 is 36
Hope this helps!

amelia mom baked 48 cookies after amelia and her friends walk in the kitchen there are 18 cookies left
Can someone please help me with all of these. And thank you.
Answer/Step-by-step explanation:
1. x = -3.6
Add 1 on both sides.
18x = 23x + 18
Subtract 23x on both sides.
Combine like terms.
Divide the answer.
-5x = 18
x = -3.6
2. x = 11/3 (2.66666...)
Add 5 on both sides.
6x = 3x + 11
Subtract 3x on both sides.
Combine like terms.
Divide the answer.
3x = 11
x = 11/3
3. x = 23
Subtract 12 on both sides.
5x = 6x - 23
Subtract 6x on both sides.
Combine like terms.
Divide the answer.
-x = -23
x=23
(that's all.)

A clothing store is having a sale on shirts and jeans. 4 shirts and 2 pairs of jeans cost $64. 3 shirts and 3 pairs of jeans cost $72. What is the cost of one shirt? What is the cost of one pair of jeans
Answer:
Shirt:8 ; jsans:16.
Step-by-step explanation:
Let’s shorten these terms: shirt=s ; jean=j.
3s+3j=72
4s+2j=64 => =2j=64-4s => j=(64-4s):2 => j=32-2s
3s+3j=72 => (instead of j we write 32-2s=> 3s+3*(32-2s)=3s+96-6s=72
=> -3s=72-96
-3s=-24
s=24:3
s=8.
=> j=32-2s => j= 32-16 => j=16.
A lookout tower above a canyon is 4 meters above ground level. The depth of the canyon is 16 meters below ground level. If 0 represents ground level, which number sentence correctly compares their distances above and below ground level?
A) 4<-16
B)4>-16
C)-4<16
D)-4>16
Answer:
B
Step-by-step explanation:
4 meters above. So 4 will not be negative, this eliminates C and D.
16 is definitely negative. So that eliminates C and D again.
< the number on the left of this is smaller than the right
> the number of the right of this is bigger than the left
4 is larger than -16
4>-16

Bernard typically runs x km/hour. While he was sick, he only ran 41. 5 km/hour. What equation represents that the difference in his speeds is 13. 5 km/hour? x – 41. 5 = 13. 5 41. 5 x = 13. 5 13. 5 – x = 41. 5 13. 5 – 41. 5 = x.
Step-by-step explanation:
Typical speed of Bernard= x km/hr
Bernard's speed while sick= 41.5 km/hr
the difference in the speed=13.5 km/hr
the equation representing the difference will be:
x-41.5=13.5 km/hr
