Answer:
(-2,-1)
Step-by-step explanation:
Midpoints are found when you do ([x(subscript A) + x(subscript B)]/2, [y(subscript A) + y(subscript B)]. Therefore your equation (for x of B) should look like this:
-4 = ([-6+x]/2)
After you solve for x, you should have gotten -2 for x.
Then you do the same for y:
2 = ([5+y]/2)
You should get -1. Your final answer should be (-2, -1)
I think you meant "wide." :) Since it is a pipe, you should know that it is the shape of a cylinder. Therefore, the formula would be: πr^2h. Substitute the height for h. (π(4.5)^2(13). Since it's 9 cm wide total, divide it by 2 to get the radius (part of formula), which is 4.5 So multiply π times 4.5^2 (which equals 20.25) times 13. This all will equal 826.605. You can simplify this decimal to 827. Therefore, the volume is 827 cm^3.
Answer:
1. 18 cent per apple
2. 84
3.$9.10
4. 460 meters
Step-by-step explanation:
1. divide 1.45 by 8 to get price per apple
1.45/8=0.18
2. convert 70% into a decimal
70%=.70
multiply by amount
120(.70)=84
3. convert 20% into a decimal
20%=.20
multiply by amount
45.50(.20)=9.10
4. 1 meter = 100 cm therefore 4.6 meters = 460 cm
