I guess 7x but it not a choice so...
In order to prove that two lines are parallel to each other, you need to show that they have the same slope.
Line 1 is perpendicular to a line that has slope m, thus it has a slope of -1/m.
Line 2 is perpendicular to the same line with slope m, thus it has a slope of -1/m.
Line 1 and Line 2 have the same slope so they are parallel.
Answer:
29/40 = 0.725 34/25 = 1.36 12/10 = 1.2 17/50 = 0.34
Step-by-step explanation:
Just divide the first number by the second number. So 29 divided by 40 is 0.725 and so on.
Since the percent increase is bigger than 100%, it definitely has to be more than 54,000.
so let's break this down:
250%= 100% + 100% + 50%
we know 100% is the whole price so if there are 2 100% we have to multiply the price by two!!!
54,000•2 = 108,000
now, 50% is half of the whole price, divide the price by two:
54,000÷2= 27,000
so add your results and you will get this!
108,000+27,000= 135,000
Answer:
![4\sqrt{\pi}](https://tex.z-dn.net/?f=4%5Csqrt%7B%5Cpi%7D)
Step-by-step explanation:
- The cross section of a sphere is a circle with area
, where radius is given as 4 - The cross section of the cube is a square with area
, where a is side length of square
The circle area = the square area. Thus we have:
![\pi r^2 = a^2 \\\pi(4)^2=a^2\\16\pi=a^2\\\sqrt{16\pi}=a\\ a=\sqrt{16} \sqrt{\pi} \\a=4\sqrt{\pi}](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%20%3D%20a%5E2%20%5C%5C%5Cpi%284%29%5E2%3Da%5E2%5C%5C16%5Cpi%3Da%5E2%5C%5C%5Csqrt%7B16%5Cpi%7D%3Da%5C%5C%20a%3D%5Csqrt%7B16%7D%20%5Csqrt%7B%5Cpi%7D%20%5C%5Ca%3D4%5Csqrt%7B%5Cpi%7D)
