Answer:
86.28 ft²
Step-by-step explanation:
The figure given consists of a rectangle and a semicircle.
The area of the figure = area of rectangle + area of semicircle
Area of rectangle = ![l*w](https://tex.z-dn.net/?f=%20l%2Aw%20)
Where,
l = 10 ft
w = 8 ft
![area = l*w = 10*8 = 80 ft^2](https://tex.z-dn.net/?f=%20area%20%3D%20l%2Aw%20%3D%2010%2A8%20%3D%2080%20ft%5E2%20)
Area of semicircle:
Area of semicircle = ½ of area of a circle = ½(πr²)
Where,
π = 3.14
r = ½ of 8 = 4 ft
Area of semi-circle = ½(3.14*4) = 6.28 ft²
Area of the figure = area of rectangle + area of semi-circle = 80 + 6.28 = 86.28 ft² (nearest hundredth)
Find how much greater 20 is than 5
20-5=15
the % is of 5, so the percent is percent out of 5
20 is x% of 5 greater than 5
20=(x%)5+5
minus 5 both sides
15=(x%)5
divide both sides by 5
3=x%
percent means parts out of 100
x%=x/100
3=x/100
times 100 both sides
300=x
answer is 300%
Answer:
No they are not proportional
Step-by-step explanation:
250/5 = 150/3.5
50 ≠ 42.857..
43 red beads
We can set up an equation to represent this problem if we substitute 'w' for the number of white beads:
6w+1+w=50
7w+1=50
7w=49
w=7
There are 7 white beads and we can multiply the number of white beads times six and add 1 to get the number of red beads.
