Here we have to know the conversion between feet and inches.
1 Feet = 12 inches (This is given and is to be known)
So the 5 feet wide footbridge when converted to inches would be about 5*12 = 60 inches
The width of the footbridge in inches = 60 inches
Each wooden plank is 6 inches,
So the number of wooden planks that are required to build the foot bridge of 60 inches = 60/6 = 10 planks
Hence, the path path is 10 planks wide
Answer: i think its implied
Step-by-step explanation:
The answer is A. -2+5i.
First you set up the problem like this: (6+2i)-(8-3i)
Then you distribute the (-) into the second parenthesis. After doing that you should have something that looks like this: 6+2i-8+3i
Then you add like terms.
Answer:
5.714 liters of the 5% solution and 4.286 of the 40%.
Step-by-step explanation:
Let x be the volume of 40% solution and y = volume of the 5% solution.
x + y = 10
0.40x + 0.05y = 0.20(x + y)
From the first equation x = 10 -y so we have:
0.40(10 - y) + 0.05y = 0.20( 10 - y + y)
4 - 0.40y + 0.05y = 2
-0.35y = -2
y = 5.714 liters of the 5%.
and x = 10 - 5.714 = 4.286 liters of the 40% solution.
