Answer:

Mean time and 13

Step-by-step explanation:

Since in the given question it is mentioned that there is a five people and they spend the work in 7,10,13,20,15 hours respectively

So here the concept i.e. used is average time or the mean time

And, this can be calculated below:

= Sum of observations ÷ number of observations

= (7 + 10 + 13 + 20 + 15) ÷ 5

= 13

chef ollie has a community garden.she uses 2/6 of the farmland to grow beets and 1/6 of the farmland to grow kale. how much of t
Lorico [155]

Answer:

1/2 of farm land left.

Step-by-step explanation:

  Ok so we know that Chef Ollie has a community garden. And that she uses \frac{2}{6} of the farmland to grow beets. The denominator 6 lets you know immediately that the land is divided into equal 6 pieces. We also know that Chef Ollie uses another \frac{1}{6} of the farmland to grow kale.

  Because the we need to find out how much land Chef Ollie has left, we need to subtract the amount she used from the whole. Before we can do that we must add up the total amount of used land, and since the denominators are the same we can directly add and subtract with having to change the denominator.

Step 1: Write down important numbers.

\frac{2}{6}, \frac{1}{6},

Step 2: Add those numbers together.

\frac{2}{6} + \frac{1}{6} = \frac{3}{6} or \frac{1}{2}

Step 3: Write an expression/equation.

\frac{6}{6} - \frac{3}{6} \\or\\1 - \frac{1}{2}

Step 4: Solve

=    \frac{3}{6}\\or\\\frac{1}{2}

(can be written both ways)

  And you get your answer: After Chef Ollie has used \frac{2}{6} to grow beets and \frac{1}{6} to grow kale, she has \frac{1}{2} of her farmland left untouched.

  To represent this you could draw a circle divided in 6 pieces and shade 3 of them, or simply draw a circle and shade half. As well as drawing a rectangle and dividing it into 6 pieces, shading 3, or draw a rectangle, and shade half.

You are welcome ;) .

You can solve this question with pythagorean theorem > {a}^{2} + {b}^{2} = c^{2}

Based on the information, you already have one side (a or b, doesn't matter, 12) and the hypotenuse (the cut, c, 15)

So: 
1. 12^{2} + b^{2} = 15^{2}
2. 144+b^{2} = 225
3. b^{2} = 225 - 144 = 81
4. b=  \sqrt{81}
5. b=9
