Answer:
5
Step-by-step explanation:
2 3/4=11/4
2 1/4=9/4
11/4+9/4=20/4=5
Answer:
9+9=18
Step-by-step explanation:
as they are positive numbers so by adding it we get 18
Answer: 96 m²
Step-by-step explanation: Surface area is the sum of the areas of all of the faces of a 3-dimensional figure.
So to find the surface area of a cube, it's important to understand that each face of a cube has the same area so we can simply find the area of one face of a cube and multiply by the number of faces which is 6.
To find the area of one face of a cube, we can use the formula for the area of a square which is S².
Since the length of a side is 4 meters, we have (4 m)² or 4 meters x 4 meters which is 16 m².
Now, since there are six sides to a cube, we have 6 (16 m)² which is equal to 96 m². So the surface area of the cube is 96 m².
135/2.2=61.36 kg
61.36x2=122.72 mg
122.72/500 x 240=58.9 ml o.j. per day

-7(z - 6) = -70
-7z + 42 = -70
- 42 -42
-7z = -112
-7z/-7 = -112/-7
z = 16
Answer: z = 16
