Answer:
x = 15 5/6
Step-by-step explanation:
-4 1/4x-7 6/8x=-190
get a common denominator 8
-4 1/4*2/2 x - 7 6/8 x = -190
-4 2/8 x - 7 6/8 x = -190
combine like terms
-11 8/8 x = -190
-12x = -190
divide by -12
-12x/-12 = -190/-12
x = 190/12
divide top and bottom by 2
x = 95/6
change to an improper fraction
6 goes into 95 15 times with 5 left over
x = 15 5/6
Answer:
3,375mm^3
Step-by-step explanation:
To find the volume, you do the length times the width times the height. Since this is a cube, the length, width, and height are all 15 mm. Multiply 15 times 15 times 15 to get 3375. The answer is 3375 cubic inches or 3375mm^3

Answer:
246 cm^2
Step-by-step explanation:
Area of the rest of cardboard = Area of square - Area of the 4 sectors
Kindly note that at each corner of the cardboard, the angle is 90 degrees
Area of square = L^2 = 20^2 = 400 cm^2
Area of a sector = theta/360 * pi * r^2
Since we have 4 sectors;
Area of sectors =4 * 90/360 * 22/7 * 7 * 7
= 22/7 * 49 = 22 * 7 = 154 cm^2
Area of the remaining part of cardboard = 400 cm^2 - 154 cm^2 = 246 cm^2
The final area will be 392,040 square feet.
The area that is to be subtracted is 110 by 30. If we multiply those, we get 3300 square meet. Now, just subtract that from 395340..
395340 - 3300 = 392040
