Divide it and get 0.6 then multiply by 100 so 60%
(I) $ 846
(II) 157.64 cm²
Step-by-step explanation:
(I)
The area of the rectangle is;
720 * 500 = 360,000
10,000 m2 = 1 hectare
Therefore to convert the area to hectare;
360,000 / 10,000
= 36
If the cost of spraying the pesticide is $23.50 per hectare, then total cost is;
36 * 23.50
= 846
(II)
To find the area of the trapezoid;
(sum of the parallel sides * height) / 2
Height is the diameter of the circle – 21 cm
((19 + 29)*21) / 2
= 504
Then the area of the circle;
πr²
π * (21/2)²
= 346.36
The shaded area;
Area of the trapezoid – area of the circle
504 – 346.36
= 157.64

Answer:
c.
Step-by-step explanation:
2 lines are cut by a transversal. At the intersection of the first line with the transversal, the bottom right angle is 130 degrees. At the intersection of the second line with the transversal, the uppercase right angle is 50 degrees.
Mean: 8
Median: 6. Since you get 4 and 8 left and the mean of 4 and 8 is 6
It is 120 because you do proportions. 540x=64800 and divide both sides by 540 and x=120
