All measures of the cube are the same so to get the volume u just multiply themselves 3 times x^3
If are AC is 122 degrees and arc BC is 192 degrees, what is the measure of angle ACB
ACB = AC + BC
ACB = 122 + 192 = 314
The answer is b. 314 degrees
Please help thank you and explain please
Answer:
x = 48
Step-by-step explanation:
first you would add them together and set it equal to 180( because a straight line is 180 degrees): 3x - 12 + x = 180
Then you add like terms( the x's): 4x - 12 = 180
now add 12 to both sides: 4x = 192
now divide by 4 on both sides x = 48
hope this helps! : )

Number of practice problems completed in 30 minutes Sample 1 14 15 16 17 16 15 16 15 17 18 Mean = 15.9 Sample 2 16 18 17 14 15 14 18 14 15 16 Mean = 15.7 Sample 3 18 14 16 15 15 14 17 15 19 13 Mean = 15.6 Which statement is most accurate based on the data? A. A prediction based on the data is not completely reliable, because the means are not the same. B. A prediction based on the data is reliable, because each sample has 10 data points. C. A prediction based on the data is not completely reliable, because the means are too close together. D. A prediction based on the data is reliable, because the means of the samples are close together.
Answer:
A
Step-by-step explanation:
The statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.
What is Mean?Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers
From the given data,
Mean of the sample 1 = 15.9
Mean of the sample 2 = 15.7
Mean of the sample 3 = 15.6
All three mean are close together.
Therefore the data is reliable
Hence, the statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.

Evaluate functions from their graph g(-9)
Please help my teacher doesn’t teach us anything and just gives us khan academy assignments and I’m really stressing out from this assignment
At the coordinate of -9, the value of the function g(-9) will be 1.
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that in the graph the function is varies with the value of the coordinates, at the value of -9 the solution for the function g(-9) will be equal to 1
g(-9) = 1
Hence, the value of the function will be 1.

what is the value of x?
Answer:
probs too late, but i think the answer is x=12
Step-by-step explanation:
the angles should add up to equal 180
180-36=144
144=8x+4x
144=12x
now divide by both sides to isolate x
12=x
u can check by plugging in ofc, 36+(8x12)+(4x12)=36+96+48=180
