Answer:
B
Step-by-step explanation: Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
If you had an equation such as 50%x=20, I would convert the percent to a decimal first. So, 0.50x=20. Then I would change the decimal into a simplified fraction. In this case it is 1/2. So, 1/2x=20. Then I would reciprocate the fraction and multiply that by 20. So x=20*2/1. From this, we would get x=40/1, but the 1 is not necessary, so we can write the final answer as x=40.
The formula is A=B*H (A=BxH)
Answer:
the answer is 8
Step-by-step explanation:
1/2(8 + 4) = 6
0.5(8 + 4) = 6
(4 + 2) = 6
6 = 6
A number that names a part of a whole or part of a whole group is called a fraction.
