Answer:

1\frac{1}{3}

Step-by-step explanation:

Given the following question:

4\times\frac{1}{3}

To find the answer simply multiply the numerators and the denominators by each other.

4\times\frac{1}{3}
4=\frac{4}{1}
\frac{4}{1} \times\frac{1}{3}
4\times1=4
1\times3=3
=\frac{4}{3}
\frac{4}{3} =4\div3=1\frac{1}{3}
1\frac{1}{3}

Hope this helps.

Arrange these numbers from least to greatest:
zmey [24]
First let's put them all over 100.
-\frac{5}{8} would change to -\frac{62.5}{100}

-\frac{7}{9} to -\frac{77.7}{100}

-\frac{4}{5} to -\frac{80}{100}

-\frac{3}{7} to -\frac{42.8}{100}

Then if we put them from least to greatest it would be from highest to lowest (since they are negatives)

-\frac{4}{5}, -\frac{7}{9}, -\frac{5}{8}, -\frac{3}{7}

The answer would be B

A cable that weighs 6 lb/ft is used to lift 500 lb of coal up a mine shaft 400 ft deep. Find the work done. Show how to approxim
stealth61 [152]

Answer:

8.2 *10^5 ft lb

Step-by-step explanation:

Wcoal = 800*500  = 400000 = 4*10^5 ft lb

Wrope =\int\limits^{400}_0 {6(400-y)} \, dy

Using a right Riemann sum

The width of the entire region to be estimated = 400 - 0 = 400

Considering 8 equal subdivisions, then the width of each rectangular division is 400/8 = 50

F(x) = 6(400-y)

\left[\begin{array}{cccccccccc}x&0&50&100&150&200&250&300&350 &400\\f(x)&2400&2100&1800&1500&1200&900&600&300&0\end{array}\right]

Wrope = 50(2100) + 50(1800) + 50(1500) + 50(1200) + 50(900) + 50(600)

+ 50(300) + 50(0) = 420000 = 4.2 * 10^5 ft lb

Note: Riemann sum is an approximation, so may not give a accurate value

work done =  Wcoal + Wrope= 4*10^5+ 4.2 * 10^5 = 8.2 *10^5 ft lb

Find the center and radius of the circle described by the equation x2 + y2 + 6x - 4y - 27 = 0.
Lesechka [4]

Answer:

Step-by-step explanation:

hello :

x²+ y² + 6x - 4y - 27 = 0 means : (x²+6x+9)-9+(y²-4y+4)-4-27 =0

(x+3)²+(y-2)² = 40....standard form when the center is (-3 , 2) and radius √40
