Check the picture below.

$\bf A)\\\\
V(w)=(w+2)(w)\left( \cfrac{w+2}{4} \right)\implies V(w)=(w^2+2w)\left( \cfrac{w+2}{4} \right)
\\\\\\
V(w)=\cfrac{w^3+2w^2+2w^2+4w}{4}\implies V(w)=\cfrac{w^3+4w^2+4w}{4}
\\\\\\
B)\\\\
V(10)=\cfrac{(10)^3+4(10)^2+4(10)}{4}\implies V(10)=\cfrac{1000+400+40}{4}
\\\\\\
V(10)=360$

what does it tell us? hmmm when w = 10, h = 3 and l = 12, that just means is a short fat box like the one in the picture.

If 10 man can work 6hours.How many more men are needed towork in 4 hours

Lerok [7]

Answer:

5 more men

Step-by-step explanation:

10 men do a job in 6 hours.

To do the job in 2 hours, 1/3 of the time, you need 3 times as many men.

30 men do a job in 2 hours.

To do the job in twice the time, 4 hours, you need half the men.

15 men do a job in 4 hours.

15 men - 10 men = 5 men

You need 5 more men.

How do i figure out 9 1/6 - 8 5/6<br> and 10 3/4 - 6 4/4?

Westkost [7]

Answer:

1) $9\frac{1}{6}-8\frac{5}{6}=\frac{1}{3}$

2) $10\frac{3}{4}-6\frac{4}{4}=3\frac{3}{4}$

Step-by-step explanation:

You can convert he mixed numbers to improper fractions:

1. Multiply the whole number part by the denominator of the fraction.

2. Add the product obtained to the numerator.

3. The denominator does not change.

Then:

$9\frac{1}{6}=\frac{54+1}{6}=\frac{55}{6}\\\\8\frac{5}{6}=\frac{48+5}{6}=\frac{53}{6}\\\\10\frac{3}{4}=\frac{40+3}{4}=\frac{43}{4}\\\\6\frac{4}{4}=\frac{24+4}{4}=\frac{28}{4}$

Observe that, in each subtraction, the denominators are equal, then you can rewrite the denominator and subtract the numerators:

$1)\ \frac{55}{6}-\frac{53}{6}=\frac{55-53}{6}= \frac{2}{6}=\frac{1}{3} \\\\2)\ \frac{43}{4}-\frac{28}{4}=\frac{43-28}{4}= \frac{15}{4}$

Divide 15 by 4. The quotient will be 3 and the remainder 3.

Then:

$\frac{15}{4}=3\frac{3}{4}$
