Step-by-step explanation:
Answer:
A=32
Step-by-step explanation:
Area of a trapezium=1/2(a+b)h
A=1/2(6+10)4
A=1/2(16)4
divide 16 by 2
A=(8)4
open the bracket
A=32
Check/ verify
A=1/2(a+b)h
32=1/2(6+10)4
32=1/2(16)4
divide 16 by 2
32=(8)4
32=32.
I hope this hopes?
Answer:5.4×105+2.3×104.

Hello from MrBillDoesMath!
Answer:
The solution set is the set all all real number m
Discussion:
3(2m-1) <= 6m-2 =>
3*2m - 3*1 <= 6m-2 =>
6m - 3 <.= 6m-2 => (Subtract 6m from both sides)
0-3 <= -2 =>
-3 < = -2
As -3 <=-2 is always true the solution set is the set all all real number m

The angles must add to 180 degrees.
Since the angles are in the ratio 7:9:4, their measures are not 7, 9, and 4 since 7, 9, and 4 do not add to 180. If you multiply 7, 9, and 4 by the same number, the new numbers will be in the same ratio. Since we do not know what that number is, we can use x for it.
Multiply 7, 9, and 4 by x to get
7x, 9x, and 4x.
Now add them and set equal to 180.
Then solve for x.
7x + 9x + 4x = 180
20x = 180
x = 9
Now that we know x equals 9, substitute x with 9 and evaluate 7x, 9x, and 4x to find the actual angle measures.
7x = 7 * 9 = 63
9x = 9 * 9 = 81
4x = 4 * 9 = 36
The angles measure 63, 81, and 36 degrees.
