Step-by-step explanation:
Ok the points are (-1, 2) and (1, -2)
Put it in the formula
d = ![\sqrt{(1 - -1)^2 + (-2 - 2)^2} \\\sqrt{(2)^2 + (-4)^2} \\\sqrt{2 + 16} \\\sqrt{18} \\](https://tex.z-dn.net/?f=%5Csqrt%7B%281%20-%20-1%29%5E2%20%2B%20%28-2%20-%202%29%5E2%7D%20%5C%5C%5Csqrt%7B%282%29%5E2%20%2B%20%28-4%29%5E2%7D%20%5C%5C%5Csqrt%7B2%20%2B%2016%7D%20%5C%5C%5Csqrt%7B18%7D%20%5C%5C)
√18 = 4.2426 ≈ 4.2

Rita's error is in the sign of 2.75 in her equation. If x is her selling price, Rita needs to find the value of x in
.. 8(x -2.75) = 78
That value will be
.. x = 2.75 +78/8 = 12.50
Answer:
24
Step-by-step explanation:
To find the volume of the cube just cube one of the sides, so 1/8^3 is 1/512
Yes it's the actual volume, it didn't get smaller it's just cubic inches instead of a line.
The rectangle's volume is 1/4*3/8*1/2 which if you change them to have the same denominator it's 2/8*3/8*4/8=3/64
Now convert 3/64 to have a denominator of 512
3/64*8/8= 24/512
24/512 divided by 1/512 is 24
You can fit 24 cubes in the rectangle.
