A solid has 6 faces and 8
vertices. How many edges
does it have?
Euler's Formula: F+ V - E = 2
Fnter
Answer:
4 edges
Step-by-step explanation:
the shape is a cube
Answer: 12
Step-by-step explanation:
Euler’s formula: F + V - E = 2
6 + 8 - E = 2
14 - E = 2
You find E by subtracting 14 with 2
14 - 2 = 12
E = 12

Answer:
452.2
Step-by-step explanation:
r x r x h x 3.14 (pi) = 6x6x3.14x4=452.16, rounded to tenth is 452.2
Answer:
452.4in³
Step-by-step explanation:
diameter= 12in.
radius= 12÷2
= 6in.
volume= πr²h
=π×6²×4
= π×36×4
= 113.097336×4

≈ 452.4in³
Is (8, 3) a solution to the system?
- x + 4y = 4
- x + 3y = 1
Answer:
Step-by-step explanation:
You can either substitute (8, 3) into both equations as a test, or you can find the solution yourself.
Rewrite
- x + 4y = 4
- x + 3y = 1
as
- x + 4y = 4
+ x - 3y = -1
and combine like terms. The result is y = 3. Then -x + 4(3) = 4, or 8 = x.
Yes, (8, 3) is a solution of this SYSTEM.

Answer:
1: x=18 2: x=7 3: x=12
Step-by-step explanation:
1: 7x+3=9x-33
2x=36
x=18
2: 16x+(6x=26)=180
22x=154
x=7
3: (10x-17)-(2x-3)=90
8x-14=104
x=12
Answer and Step-by-step explanation:
1.
7x + 3 = 9x - 33
Subtract 7x from both sides, and add 33 to both sides of the equation.
36 = 2x
Divide both sides by 2.
x = 18
2.
6x + 26 + 16x = 180
Combine like terms.
22x + 26 = 180
Subtract 26 from both sides of the equation.
22x = 154
Divide 22 from both sides of the equation.
x = 7
3.
90 + 2x - 3 = 10x - 17
Add 17 to both sides of the equation, subtract 2x from both sides of the equation and combine like terms.
104 = 8x
Divide 8 from both sides of the equation.
x = 13

A rectangular room is 7 times as long as it's wide and it's perimeter is 64metres. Find the dimension of the room.
Answer:
Length = 28 meters Width = 4 metersStep-by-step explanation:
Assume the width of the rectangle is x. That means that the length of the rectangle is 7x which is 7 times as long as it is wide.
Perimeter of a rectangle:
= Length + length + Width + Width
Therefore:
7x + 7x + x + x = 64
16x = 64
x = 64/16
x = 4 meters
Length is 7 times as long:
= 4 * 7
= 28 meters

Find the value of x. -1x + 72 = -3x + 84
Answer:
x=6
Step-by-step explanation:
First, add x to each side.
72=-2x+84
Subtract 84 from each side
-12=-2x
Dive each side by -2
6=x
Answer:
x=6
Step-by-step explanation:
-1x+72=-3x+84
+3x on both sides
2x+72=84
subtract 72 on both sides
2x=12
divide by 2 on both sides
x=6

In order, range, median, mode and mean. Round the mean to the nearest tenth.
PLS HELP ASAP
Answer:
Range: 40
Median: 55
Mode: 72
Mean: 54.6
Step-by-step explanation:
First, let's put all of the numbers down.
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
Now, to find the range, subtract 72 - 32 = 40
To find the median, find the number in the middle
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
Because there are an even amount of numbers we will find the mean of those two numbers which would be 55.
To find the mode, look for the number that appears the most.
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
To find the mean, add everything up.
32, + 34, + 35, + 40, + 41, + 54, + 54, + 56, + 63, + 69, + 70, + 72, + 72, + 72 = 764
Then, divide. 764 ÷ 14 = 54.6 when rounded to the nearest tenth.
I hope that this helps, and you have a great day! :)
Solve by graphing.
2x +y=1
x – 2y = 8
The solution to this system of equations is:
x-coordinate:
y-coordinate:
Given:
The given system of equations is:
[tex]2x+y=1[/tex]
[tex]x-2y=8[/tex]
To find:
The solution to this system of equations by graphing.
Solution:
We have,
[tex]2x+y=1[/tex]
[tex]x-2y=8[/tex]
The table of values for first equation is:
x y
0 1
1 -1
Plot the points (0,1) and (1,-1) on a coordinate plane and connect them a straight line.
The table of values for second equation is:
x y
0 -4
2 -3
Plot the points (0,-4) and (2,-3) on a coordinate plane and connect them a straight line.
The graphs of given equations are shown in the below figure.
From the below figure, it is clear that the lines intersect each other at point (2,-3). So, the solution of the given system of equations is (2,-3).
Therefore, the solution to this system of equations is:
x-coordinate: 2
y-coordinate: -3
What is the equation of a line parallel to the y axis and passing through the point (2,1)?
Answer:
x = 2
Step-by-step explanation:
lines parallel to the y-axis are always vertical and begin with 'x ='
Answer:
x=2
Step-by-step explanation:
Hi there!
A line parallel to the y-axis would make it a vertical line. Vertical lines have the equation x=d, where d is the x-intercept (the value of x when y=0).
We also need to know that every point a vertical line passes through has the same x-coordinate. Therefore, because this line passes through the point (2,1), we know that the x-intercept is (2,0).
Therefore, the equation of the line would be x=2.
I hope this helps!

Step-by-step explanation:
6.50 for the first hour only being charged once and the 5.75 being for the number of hours (n) she works after the first hour
Answer:
B
Step-by-step explanation:
n is how many additional hours after the first hour she babysits. She charges $5.75 for each additional hour. So, that would be:
5.75n
But for the first hour, she charges 6.50. So that would be:
6.50+5.75n
The graph below shows the equation y=2x+4
2
In the space below, describe the effect on this graph if the equation were changed to y=3x+4
Answer:
C. the lines will be intersecting but neither parallel nor perpendicular
Step-by-step explanation:
changing the x coeficient means you're changing the gradien/ slope. so it will intersecting in one point of y if the x = 0
y = 2x + 4
y = 2(0) + 4 = 4
y = 3x + 4
y = 3(0) + 4 = 4
Answer:
Step-by-step explanation:
If you type this equation onto the graphing calculator you can clearly tell the lines intersect therefore the right answer is the last one.

Sarah hiked a path that took her from 34 feet below sea level to 52 feet above sea level . What was the change in her elevation?
Answer:
86 ft
Step-by-step explanation:
First method: Logical thinking
Think of the position 34 ft below sea level as -34.
The position above sea level is 52.
You need to find the distance between -34 and 52.
You go from 34 ft below sea level, -34 to 0. That is 34 ft.
Then you go from sea level, 0 ft, to 52 ft above sea level. That is 52 ft.
The total is 34 ft + 52 ft = 86 ft
Answer: 86 ft
Second method: Calculate a distance in math
The distance between two points on a number line is the absolute value of the difference of their coordinates. The coordinates are -34 and 52. Subtract the numbers in either order, and take the absolute value of the difference.
|-34 - 52| = |-86| = 86
If you did it in the other order, you'd get the same answer.
|52 - (-34)| = |52 + 34| = |86| = 86
Answer: 86 ft
