Assuming that this field is rectangular with 2 semi-circles (one on both ends of the field), we must first calculate the total area of the field. this is done by adding the area of the rectangular portion and the circular portion. This is done below:
Given:
Rectangular length = 95 yards
Rectangular width = semi-circle diameter = 49 yards
Area of rectangle = length * width = 95 * 49
Area of rectangle = 4655 yd^2
The area of the 2 semi-circles can be obtained by treating both as one circle.
Area of circle = pi * (d/2)^2 = 3.1416 * (49/2)^2
Area of circle = 1885.74 yd^2
Total area = 1885.74 + 4655 = 6540.74
We multiply the area by the cost of fertilizing:
Total cost = cost per sq. yd * total area
Total cost = 0.08 * 6540.74
Total cost = $523.26
To check, we can solve how much sunscreen is in a family sized bottle first. We need to find what is 20% of 12. First, turn 20% into a decimal: 20%/100= 0.2. Now, multiply 0.2 by 12, which is 2.4. Then, you add this to 12 because it is 20% more. 12+2.4= 14.4. Multiply this by 4: 14.4*4=57.6. Since his number is close to 50, he is kinda correct, but a much more reasonable answer would be closer to 60. Hope this helped!
Answer:
Step-by-step explanation:
(–5g^5 h^6)^2 × (g^4 h^2)^4 the ^ carot symbol means raised to power X
(25 g^10 h^12) × (g^16 h^8) exponents raised to powers MULTIPLY
-5² = 25 g^5² = g^10 h^6² = h^12 do the same thing with (g^4 h^2)^4
25 g^(10+16) h^(12+8) collecting terms powers ADD
25 g^26 h^20 Which letter is the answer?

Answer:
- Q1. 86°
- Q2. B(2,0), D(3,1)
Step-by-step explanation:
Q1
<u>The angle of rotation is twice the angle of intersection:</u>
Q2
<u>Dilation by a scale factor of 2 resulted in:</u>
- (x, y) → (2x, 2y) for each point C' and D'
<u>The endpoints of the original segment are:</u>
- C = (4/2, 0/2) = (2, 0)
- D = (6/2, 2/2) = (3, 1)
Correct choice is B
