Answer:
30.3m^2
Step-by-step explanation:
I started off by finding the area of the semi circle. The formula πr^2 divided by 2. The radius of the circle is 2 because it is half of the diameter which is 4. So π(2)^2 divided by 2 is 6.3.
Next I broke apart the the shape into a rectangle and a triangle for simplicity sake. So doing this I had to know where to cut and if you look at the top of the figure it shows 2m for the length at the top. So I put a vertical line there. Thus changing the 10m on the bottom to a 8m section and a 2m section. So the rectangle's area will be the length times the height which is 2x4=8.
The triangle's area can be found with the equation BH/2 and we the 8 base we found and a height of 4 it is 8x4/2. Which ends up as 16.
Finally you add up all three area's that you found 8+16+6.3=30.3
Hi there. :)
I'll try to make this simpler for you.
Let's focus on the equation from left to right, to avoid clutter.
-4(3 * 1/2) = -4(1.5)
Now to the right.
+ 2(3) = + 6
Now combine!
-4(1.5) + 6 =
-6 + 6 = 0
The answer is 0.
Answer: 3. 26
Step-by-step explanation:
For how many years?
In any case I will give you the formula & you will plug into the number of years"
Remaining Value (or Salvage Value) = initial cost(1 - rate%)^n(number of years
Remaining value after n years = 15000(1-23%)^n
Answer:
129° and 37°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
(a)
∠ 1 is an exterior angle, thus
∠ 1 = 62° + 67° = 129°
(b)
∠ 1 + 115° = 152° ( subtract 115° from both sides )
∠ 1 = 37°
