Answer:
Area of big circle: 2463.01
Area of little circle: 615.75
Area of shaded space: 1,231.51
Step-by-step explanation:
thats what i came up with
First, 7 x 10 = 70, you now have 30 left, 7 x 4 = 28. 10 + 4 = 14 with a remainder of 2. That is your answer though many would put “14 2/7” as the answer with the 2 over the 7 because its the remainder over what was getting divided first. thus 100/7 is has the remainder of 2 with the quotient 14.
<span>5x−y=8 ; y = 5x - 8
7x+4y=22
substitute </span>y = 5x - 8 into 7x+4y=22
7x+4y=22
7x+4(5x - 8) = 22
7x + 20x - 32 = 22
27x = 54
x = 2
y = 5x - 8
y = 5(2)- 8
y = 10 - 8
y = 2
answer: x = 2 y = 2 or (2,2)
Answer: 88in^2
explanation: by separating the figure into easier pieces, simple triangles and rectangles, this problem becomes much easier.
by looking the overall length of the figure, we get 7, if you cut off the big rectangle in the middle from that seven, you end up with a diamond with a height of 10 and a length of 4. multiply those together to get the area of the points on either side.
10 x 4 = 40
now looking back at the rectangle, by adding up the heights, you get a height of 16. multiply this with the length of 3 and you get 48.
add the two and you get the total area.
40 + 48 = 88
8 and 19, because 2 times the length + 2 times the width = 54 :)
