Answer:
x = 50°
Step-by-step explanation:
The sum of angles on a line is equal to 180°.
Therefore,
x + 130° = 180°
x = 50°
Answer:
answer is 50 u add x plus 130 equals to 180

Are the two expressions equivalent when x=6?
4(3x+x)
12x
Answer: No.
Step-by-step explanation:
We are already given the value of x, so all we have to do is substitute the value of x into the expressions.
For the first expression :
1. Substitute the value of x (in this case the value of x is 6) into the expression. Like this: 4(3(6)+6)
We need to put the 6 next to the 3 into a parenthesis because an x next to a number means 3 times the value of x. The parenthesis symbolizes multiplication. So, 3x is the same as 3(6).
2. Solve the parenthesis "3(6)". All we would have to do is multiply 3x6. 3x6 = 24. Now the expression looks like this: 4(24+6)
3. Solve the parenthesis. All we have to do is multiply 4x24 and 4x6. We know 4x24 = 96. And, 4x6 = 24. So, we just fill that in. It will look like this: 96+24
4. Add it up. 96+24 is 120. So, the first expression equals 120.
For the second expression :
The second expression is simple. As I said before, a number next to x means x multiplied by that number, just like parenthesis. So, we would substitute the x to 6 and put that in parenthesis. Like so: 12(6).
Now, just multiply that. 12x6=72. So, the second equation is equivalent to 72.
Summary:
The first expression is equivalent to 120. The second expression is equivalent to 72. These two numbers are not equivalent. So, the expressions are not equivalent when x=6.
How the solving process would look for the first expression :
4(3x+x)
4(3(6)+x)
4(24+6)
96+24
120
How the solving process would look for the second expression :
12x
12(6)
72

A prism has right-triangular bases with side lengths of 3 cm, 4 cm, and 5 cm.
Part 1) If the volume of the prism is 576 cm³, what is its surface area?
Part 2) If you shrink the prism to create a similar prism with a volume of 9 cm³, what is the new surface area?
Answer:
volume of prism: S(base) * height = 576
Write an equation for this table of linear data.
y=-5-x
Step-by-step explanation:
x value for 0 which is y=-5 in this case then your going to find the difference between the the the 0 x value and another one in this case I used x value for -2 where y =-3 and i see that going into the negatives added 2 so for then I would get that x is a negative number and I went down two values and it got me up 2 values meaning that x is subtracting whatever your x value is
Which formula describes the following geometric sequence? Remember that n represents the term number.
2, 6, 18, 54, ...
Answer:
The formula on nth term is l=ar^(n-1)
The 1st term is 2 & r,the ration =3
Then is 2x3^(n-1). Mind you (n-1) is an exponent on 3

Answer:
should be 65
Step-by-step explanation:
first with triangles you split it in half so A=bh
b means base h means hight then you multiply the b and h when you get that you divide by 2 because you split it in 2 bhh

What is an outlier?
a group of data points around a value
a graph showing the relationship between two sets of data
a relationship between two variables
a data point that does not fit the general pattern in the data
Answer:
Your answer would be D, an outlier is a number that sets itself apart from the rest of the data.
Example:
23, 1, 25, 28, 31
The outlier here would be 1, as it sets itself apart from the rest of the data.
*Sorry if this doesn't help or is wrong*
Answer:
I’m pretty sure it’s D a data point that does not fit the general pattern and data

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 16 feet and a height of 19 feet. Container B has a radius of 18 feet and a height of 18 feet. Container A is full of water and the water is pumped into Container B until Container A is empty.
To the nearest tenth, what is the percent of Container B that is empty after the pumping is complete?
Answer:
16.6%
Step-by-step explanation:
You want the fraction of container B, a cylinder with radius and height of 18 ft, that remains empty after the contents of container A are pumped into it. Container A is a cylinder with radius 16 ft and height 19 ft.
VolumeThe volume of a cylinder is given by the formula ...
V = πr²h
FractionThe fraction of container B that is full after container A is emptied into it is ...
Va/Vb = (π(16 ft)²(19 ft))/(π(18 ft²)(18 ft)) = (16²·19)/18³
The fraction of container B that is empty, is the difference between 1 and this amount:
V'b = 1 -(16²·19)/18³ ≈ 0.166 = 16.6%
About 16.6% of container B remains empty.
