Answer:
The answer would be .39
Step-by-step explanation:
So first we have to know the eqation to finding the area of a semicircle, this would be:
2r x π ÷ 2 (r stands for radius)
Ok so since our diameter is 2 we need to divide that in half to find our radius which we would then get .5
And then you we would fill in the blanks and make our eqaution :
2 x 0.5 x 3.14 ÷ 2 which would give us the answer of .39
i have no idea if this is right so pls lmk!
Answer:
480
Step-by-step explanation:
When solving for a variable, you get the variable you're trying to solve for on one side and everything to the opposite of that variable.
We have the equation <span>5w + 9z = 2z + 3w.
Usually the variable we're solving for we want on the left. But it's fine to have it on the right side, too.
Let's subtract 9z from the left-hand side. That way, the 5w will be alone on the left-hand side.
And remember, anything we do on one side we do to the other side.
</span><span>5w + 9z - 9z = 2z + 3w - 9z
</span><span>5w = -7z + 3w
The 3w term on the right-hand side needs to be removed. So, subtract each side by 3w.
5w - 3w = -7z + 3w - 3w
2w = -7z
Now, we need to divide each side by 2 to see what the w variable is equal to.
2w / 2 = -7z / 2
w = -7z / 2 or w = -3.5z
So, w is equal to -3.5z.

Answer:
- 7 - i
Step-by-step explanation:
Given
(- 10 - 2i) + (3 + i) ← remove parenthesis
= - 10 - 2i + 3 + i ← collect like terms
= - 7 - i
