Here is a picture of a cube, and the net of this cube. What is the surface area of this cube?
Answers
Answer: 864mm
Step-by-step explanation:
A cube has 6 faces and each side of the face is 12mm. Cubes are square, so each of the sides is the same value.
We take 12mm x 12mm = 144mm as an area for ONE side.
There six sides, so take 144 x 6 = 864
The area is 864mm
34.0157 (inches)
86.4 (cm)

17 + x = 6 please help need fast
Answers
Answer:
x= -11
Step-by-step explanation:
17 + x = 6
Get x by itself on the left side of the equal sign by doing the opposite of (+) which is (-)
So subtract 6 - 17 = -11
So now we have:
x = -11
This is true:
17 + (-11) = 6
17 - 11 = 6
6 = 6
Answer: x = - 11

Patricia and Greg are both planting rectangular flower gardens. Patricia’s garden measures 7 ft × 12 ft .Greg’s garden measures 8 ft. × 15 ft. Each garden will have a fence put around it. Including tax, the fencing materials cost $1.25 per foot.
Answers
Answer:
Patricia = $47.5 ;
Greg = $57.5 ;
$10
Step-by-step explanation:
Perimeter of a rectangle : 2(l + b)
Patricia :
7ft * 12 ft
2(7 + 12) = 2(19) = 38 ft
Total fencing cost :
1.25 * 38 = $47.5 ft
Greg:
8ft by 15ft
2(8 + 15) = 2(23) = 46ft
Total fencing cost :
1.25 * 46 = $57.5
Difference in cost :
57.5 - 47.5 = $10

Critical value = -1.677
We find t test

= -0.2/0.9/√50
= -1.5713
-1.5713 is greater than -1.6777 so we fail to reject the null hypothesis
Using excel p value = 0.061 which is greater than 0.05
So we conclude that college students sleep less than typical american

Airport A is located on a coordinate plane at (-18, 14). Airport B is located at (8, 14). How far apart are the airports?
Answers
Answer:
26 units
Step-by-step explanation:
Use the distance formula, d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2[/tex]
Plug in the points:
d = [tex]\sqrt{(-18 - 8)^2 + (14 - 14)^2[/tex]
Simplify:
d = [tex]\sqrt{(-26^2 + (0)^2}[/tex]
d = [tex]\sqrt{676}[/tex]
d = 26
So, the airports are 26 units apart

=============================================================
Explanation:
Refer to the diagram below.
Draw a line through point D such that it is perpendicular to side BC. This new line intersects BC at point E.
In other words, E is on BC such that segments DE and BC are perpendicular.
Notice how triangle CED is a right triangle with legs DE and EC. The hypotenuse is DC = 16.
Let h be the height of the trapezoid. It's also the height of triangle CED where EC is the base. In other words, h = length of DE.
--------------------------------------
Focus on triangle CED. We'll use the sine ratio to find h
sin(angle) = opposite/hypotenuse
sin(C) = DE/DC
sin(30) = h/16
0.5 = h/16
0.5*16 = h
8 = h
h = 8
The height of triangle CED is 8, so the height of the trapezoid is also 8.
--------------------------------------
Apply the area of a trapezoid formula
Area = height*(base1+base2)/2
A = h*(b1+b2)/2
A = 8*(27+21)/2
A = 8(48)/2
A = 8*24
A = 192
The trapezoid's area is 192 square units

Step-by-step explanation:
1. the equation of the required line in slope-interception form is:
y=s*x+i, where s - slope, i - interception;
2. according to the condition s=2, then the required equation is:
y=2x+i;
3. if the point (-3;8) belongs to the required line, it is possible to substitute their coordinates into the required equation and calculate the value of 'i':
8=2*(-3)+i; ⇒ i=14.
4. if s=2 and i=14, then the required equation of the line is:
y=2x+14.
