Total height of lumber, H = 10 1/2 feet = 21/2 feet .
Height of side panel, h = 5 2/3 feet = 17/3 feet .
Now,
Extra lumber required, L = 2 × Height of side panel - Total height of lumber
![L=[2\times (\dfrac{17}{3})]-\dfrac{21}{2}\\\\L = \dfrac{5}{6}\ feet](https://tex.z-dn.net/?f=L%3D%5B2%5Ctimes%20%28%5Cdfrac%7B17%7D%7B3%7D%29%5D-%5Cdfrac%7B21%7D%7B2%7D%5C%5C%5C%5CL%20%3D%20%5Cdfrac%7B5%7D%7B6%7D%5C%20feet)
Therefore, extra lumber required is 
feet.
Hence, this is the required solution.
B = rising slowly
C = constant
D = falling quickly
This graph could be an example of the Microsoft Share in the stock market.
Solution :
Give that a shark can chase prey about 30 miles per hour.
1 hour = 60 minute
by using unitary method, we will convert miles per hour into miles per minute
in 60 minutes the shark can chase the prey 30 miles
In 1 minute the shark can chase 
Hence the shark can chase the prey about 0.5 miles per minute.
Okay. So, the line shaded would have to be left to 2, because it's less than 2. In that case, A and C are eliminated, because they shade to the right, not left. B and D do this, but wait. The dotted line has to represent the less than, because the one that's fully filled in would mean less than or equal to. B would make sense, because the line is dotted and that makes an inequality symbol of less than, not less than or equal to. The answer is B.
Note: When the sign is < or >, the line on the graph is dotted. If the sign is <= or >=, then the line on the graph is solid.
Answer: There are 60 girls and 40 boys at the bar-b-que
============================================================
Explanation:
b = number of boys
g = number of girls
"The ratio of boys to girls is 4:6" so
b = 4*x
g = 6*x
where x is some positive whole number
Add up the counts of boys and girls. This count should equal 100
b+g = 100
Plug in b = 4x and g = 6x. Then solve for x
b+g = 100
4x+6x = 100
10x = 100
10x/10 = 100/10 ... divide both sides by 10
x = 10
If x = 10, then
b = 4*x = 4*10 = 40 ---> there are 40 boys
g = 6*x = 6*10 = 60 ---> there are 60 girls
we can see that the ratio
40 boys: 60 girls
reduces to
4 boys: 6 girls
In other words, for every 4 boys, there are 6 girls. The ratio 4:6 can be fully reduced to 2:3 which means for every 2 boys, there are 3 girls.
Side note: if the ratio of vegetarian girls to omnivorous girls is 1:1, then there are 30 of each
we can solve y+y = 60 to find that y = 30, or we can simply divide 60 in half to find this count. Saying "a ratio of 1:1" means that there are the same number of vegetarians as omnivorous girls.
