Answer and explanation:
To find : Calculate to the nearest 1/10th meter the length of the side of a 7th, 12th, and 30th hectare square plot.
Solution :
The area of the square is given by,
where s is the side length.
We know, 
1) The area of square plot is 7 hectare.
Area in meter square is 
Substitute the value in the formula,
Side nearest to 1/10th meter is 264.8 meter.
2) The area of square plot is 12 hectare.
Area in meter square is 
Substitute the value in the formula,
Side nearest to 1/10th meter is 346.4 meter.
3) The area of square plot is 30 hectare.
Area in meter square is 
Substitute the value in the formula,
Side nearest to 1/10th meter is 547.7 meter.
All you have to do is divide the 120 by 4 because you will be splitting it up into a individual hour. So 120 divided by 4 = 30.
The plumber charges $30/hour.
First we see the cost of making 200 cookies:
(200) * (1.50) = 300 $
Then, we see the amount of cookies that are not broken:
(200) * (0.30) = 60
200-60 = 140
Arley wants to 50% markup on cost and produces 200 cookies:
(300) * (1.50) = 450 $
Arley can sell the broken cookies for $ 1.40 each:
(1.40) * (60) = $ 84
For each unbroken cookie the price will be then:
(450-84) / (140) = 2.61 $
Answer:
Arley should charge $ 2.61 for each unbroken cookie
Answer: 1 and 3
Step-by-step explanation: math is easy
Answer:
x=2
Step-by-step explanation:
5 ( x - 2) + 4 ( 3 + x) = 20
Distribute
5x -10 +12 +4x = 20
Combine like terms
9x +2 = 20
Subtract 2 from each side
9x+2-2 = 20-2
9x = 18
Divide each side by 9
9x/9 = 18/9
x = 2
