Need to find surface area

Mathematics

Find the area for each shape.

For the triangle face you would do 4 times 6 divided by 2. Then times it by 2 because there are two triangle faces.

For the rectangle face do 5 times 12, then times 3 because there are 3 triangle faces.

Finally add both numbers together to get the surface area.

You have to break it down into their individual shapes
1st there are two triangles
To find the area for one of them
1/2bh. Or 1/2(4)(6()=12
Multiply the 12 by 2
The area for both triangles are 24
Although there are three triangles, you have to realize that only two of them have the same area
The base is 6*12=72 and there is only one of them
The two side rectangles are
5*12=60 multiply by 2 since there are 2
120

Add all of the areas together
24+72+120=216
Surface area 216 u^2

Write the equation of the line that passes through the points (2,-6) and (6,-6).
NeTakaya

Answ

Step-by-step explanation:

Two point slope =-(-6+6)/(6-2) =0

Equation is y+6 = 0(x-2)

y+6=0

y=-6

The point is -6 at y axis which is a horizontal line.

Answer:

C

Step-by-step explanation:

A triangle always consists of it being 180 degrees. The box on the triangle on angle A depicts that it is a right angle, 90 degrees. And since Angle B is given at 45, angle C must be 45 degrees as well, since 180-45-90 (triangle angles=given angles for A and B) equal up to 45. When the angles beside the right angle is both identical and the same, the sides that correspond with that triangle is also the same. AC is given at 9 feet, and since Angle C and B both have the same angles, AB must ALSO be a 9ft.

Now, since we know the two sides, it is very easy to find BC, or the hypotenuse of the triangle, using the Pythagorean Theorem: a^{2} +b^{2} =c^{2}, where a and b are sides, and c is the hypotenuse (or the long end) of a right triangle.

We can plug both 9s in for a and b since they're both the same, and it should equal to

9^2+9^2=c^2.

9^2 is 9*9, and that is 81. We have two of these so add them together to find 162. Since c^2 is equal to 162, we would need to square root both sides so we can find a number that equals c.

\sqrt{162} =c

We can either plug this into a calculator, and we should get something around 12.72, and that would be the same as C if you plug that value into a calculator.

You can also simplify the radical if you know how to. 162 is 81 times 2 (example) and 81 is 9*9, so we can add that to the outside and 2 is still under the radical. But this would only make sense if you know how to do that.

kenny6666 [7]
Milli means 1000
1 meter=1000 milimeters

therefor
9 times 1 meter=9 times 1000 milimeters
9 meter=9000 milimeters
