Answer:
B
Step-by-step explanation:
2.97 divided by 11= 0.27
2.88 divided by 12= 0.24
3.68 divided by 14= 0.26
3.75 divided by 15= 0.25
Answer:
<h3>#1</h3>
<u>Trapezoid</u>
- A = (b₁ + b₂)h/2
- A = (4.8 yd + 29.4 ft)(8 yd)/2 = (14.6 yd)(4 yd) = 58.4 yd²
<h3>#2</h3>
<u>Rectangle</u>
- A = ab
- A = 2 yd * 3.1 yd = 6.2 yd²
<h3>#3</h3>
<u>Equilateral triangle</u>
- A = √3/4a²
- A = √3/4(10²) = 25√3
<h3>#4</h3>
<u>Regular octagon</u>
- A = aP/2
- A = 14.5(12*8)/2 = 696
Answer:
Step-by-step explanation:
y= 2x+4.
-x- 5y=2x+4
-2x+y=4
-3x-5y
To solve this problem you must apply the proccedure shown below:
1. Clear the radius from the formula for the circumference of a circle and substitute values, as following:
![C=2\pi r\\ r=C/2\pi \\ r=37.699in/2\pi \\ r=5.99in](https://tex.z-dn.net/?f=%20C%3D2%5Cpi%20r%5C%5C%20r%3DC%2F2%5Cpi%20%5C%5C%20r%3D37.699in%2F2%5Cpi%20%5C%5C%20r%3D5.99in%20)
2. Substitute the radius calculated into the formula for calculate the surface area of the sphere:
![SA=4\pi r^{2} \\ SA=4\pi(5.99in^{2})\\ SA=450.88in^{2}](https://tex.z-dn.net/?f=%20SA%3D4%5Cpi%20r%5E%7B2%7D%20%5C%5C%20SA%3D4%5Cpi%285.99in%5E%7B2%7D%29%5C%5C%20SA%3D450.88in%5E%7B2%7D%20%20)
The answer is: ![450.88in^{2}](https://tex.z-dn.net/?f=%20450.88in%5E%7B2%7D%20%20)
1.b 2.34 is the correct answer
