Answer:
Perimeter: 18 ft
Height: 7 ft
Base Area: 12
Surface Area: (7)*(8) + 2(47) = 150
Step-by-step explanation:
To find the perimeter add all the edges together.
5 + 5 + 8 = 18
To find the height look at the diagram. 7ft shows the height of the rectangle and thus is the height for the rest of the shape.
Base Area:
Multiply the length (8ft) of the base by the height of the base (3ft)
8 * 3 = 24
Then divide by 2 to get the total area of the triangle
24 / 2 = 12.
Surface Area:
To find the surface area you to need to find the specifics of each side.
The base area we already solved for which is 12. We'll get back to this in a minute. The other double sides are of 5 * 7. That equals 35. Add together 12 + 35 to get 47. That is what will go in the 2(___) box because both of those sides have 2. It is the same number when done this way versus just adding them up.
47 * 2 = 94
12 + 12 + 35 + 35 = 94
Then for the (___)(___) that would be 7ft * 8ft because it is the only side left and does not have a double so it must be separate.
7 * 8 = 56
56+94 = 150
The answer is 1. its a cube, 2. the area is 294 Square CM
Answer:
y = 1 and x = - 6
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c ( where c is the value of the y- coordinates the line passes through )
The line passes through (- 6, 1 ) with y- coordinate 1 , then
y = 1 ← equation of horizontal line
The equation of a vertical line parallel to the y- axis is
x = c ( where c is the value of the x- coordinates the line passes through )
The line passes through (- 6, 1 ) with x- coordinate - 6 , then
x = - 6 ← is equation of vertical line
Answer:
4.5
Step-by-step explanation:
The scale factor is 2
This means that the sides are proportional by a factor of 2.
In other words, you multiply 2 with the side lengths of first trapezoid to get the side length of second trapezoid.
You can see the pattern:
12 goes with 24
4.5 goes with 9
7 goes with 14
<u>X goes with 9</u>
<u></u>
The "X" is the missing side.
As you can see, we multiply each number on the left-hand side by 2 to get the number on the right-hand side (larger trapezoid).
So, that means:
X multiplied by "2" will gives us 9, we can write:
Complete the equation and find x:
The missing side length in the original trapezoid is "4.5"
