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
Answer:
Question 2) 96 Question 3) 246
Step-by-step explanation:
Question 2:
The area of one side of the square is 4x4 which is 16 then you know a cube has 6 sides so 16x6 which is 96.
Question 3:
Well we know the two sides are squares with 3x3 which is 9 and then there are two so 9x2 which is 18
Then the front side with dimensions of 19x3 which is 57 and we know there are 4 sides so we do 57x4 which leads us to 228
Then we add 18 and 228 to find 246
Answer:
the answer is x<2
−2x+2>3x−8
Step 1: Subtract 3x from both sides.
−2x+2−3x>3x−8−3x
−5x+2>−8
Step 2: Subtract 2 from both sides.
−5x+2−2>−8−2
−5x>−10
Step 3: Divide both sides by -5.
−5x

4% of $1500 is 0.04 x 1500
= 60
So each month, $60 interest is saved
180 ÷ 60 is 3, so therefore the money was in the bank for 3 months.
